In the future, a lot of things in smart cities will happen automatically: the application of the clinic, based on the data from the fitness bracelet, will sign up for a medical examination, and the city services will clean the trash can according to the data from the sensors. Artificial intelligence will identify people with weapons in the crowd, and the fire brigade will go to the place before the call of eyewitnesses – on a signal from video cameras.

Wi-Fi is an integral part of the digital infrastructure that is being deployed in major cities around the world. Most often, its development is hampered by a lack of Wi-Fi investment and the unpreparedness of cities for technological changes.

If these obstacles are overcome, the state and business will be able to interact more effectively with residents and change the urban environment to suit their needs. Studies shows that free Wi-Fi can change life in the city, infrastructure management and give new opportunities to private and public companies.

Tourists and startups choose Wi-Fi

The rise of Wi-Fi could turn cities into technology hubs, with fast public internet attracting young entrepreneurs. For example, in Lithuania, according to Ooma, the fastest public Wi-Fi in the world – it is to him that the mayor of Vilnius assigns a big role in turning the city into a startup hub in Eastern Europe. Wi-Fi also affects tourist activity. The quality of public Wi-Fi is one of the main factors in tourist satisfaction . For these reasons, in Taiwan, two years after the launch of free Wi-Fi for citizens, free access to the public network was also given to guests of the island.

Some countries use free Wi-Fi as one of the gentrification tools. Together with other measures – the emergence of public spaces, subsidies for small businesses – this helps to increase the attractiveness of residential areas.

Now city authorities and businesses that make money on advertising in networks are investing in this. But in the future, operators of “home” Wi-Fi may join the creation of public networks. For example, Comcast, Fon, and Liberty Global are running projects in which city residents provide a small portion of home Wi-Fi power to city networks, and users switch between these points as they move between homes.

Wi-Fi controls road traffic and utilities

Wi-Fi allows you to plan urban infrastructure based on anonymized aggregated data. Like many Internet resources, the network can predictively determine the approximate age of the user, gender and interests. And if there are many young people with children in the area, for example, the authorities can plan the construction of new kindergartens.

One of the main areas Wi-Fi is transforming is transportation. Networked video cameras, touch sensors, smart fare terminals and other gadgets help analyze traffic in public transport and suggest new interchanges, adjust the number of buses, reschedule stops, etc.

In UAE, Wi-Fi is available almost everywhere. It is he who is used by city services to manage the life of the city. To control traffic on the roads, there is an intelligent transportation system that relies not only on a network of gadgets installed on the roads, but also on sensors, cameras and GPS devices that are in a taxi.

Moreover, the system makes it possible to adapt the urban environment for people with disabilities – for example, it automatically identifies them at crossings and increases the green light time.

In UAE, public Wi-Fi is available almost everywhere. Even trash cans give it away.
Wi-Fi also powers other services that enable cities to collect big data, reduce costs, and improve service efficiency—smart parking and smart lighting, smart video surveillance, and automatic water and power supplies.

For example, in Dubai Downtown, smart lighting systems are powered by city Wi-Fi, a key element of the city’s carbon neutral strategy to reduce carbon dioxide emissions.

Even as hospitals around the world are cutting back on non-COVID-19 patients, Wi-Fi is helping patients with other ailments take advantage of telemedicine.

Giving away free internet on the hospital grounds will aloow visitors to consult a doctor without leaving their car. Those who do not have a phone or computer with them can be given a tablet in the parking lots with installed software for communicating with doctors.

Florence has reduced traffic congestion with its “ Smart Traffic Management ” program by adding a few hundred more devices to its existing network of cameras and Bluetooth sensors. They are interconnected and transmit information via Wi-Fi to the local traffic police and administration. Based on the data, these authorities manage traffic lights and parking lots in the city.

Wi-Fi will attract customers who pass by

Not only city services get the opportunity to change their work. For offline businesses, especially local ones, Wi-Fi is a new way to communicate with potential buyers. Businesses such as a hairdresser, a repair shop, a coffee shop cannot yet transfer their services online, but it becomes easier to get to know the consumer virtually.

This is possible with the help of smart phone MAC address identification technology. The business engages with an audience that has recently been around through Wi-Fi ads when they connect and through social media or SMS. The owner can target ads to potential visitors to a particular establishment instead of buying huge coverage of an unnecessary audience.

In addition, both private and public companies can use Wi-Fi to personalize the user experience. This possibility seems too futuristic for now, but it is quite feasible in the near future.

Users will be able to customize their preference profiles in the services of Wi-Fi operators. Then, for example, when entering a train compartment, lighting, temperature, types of entertainment content and other parameters will automatically adjust to the user.

Anonymized data will allow you to offer users the necessary services. Thus, urban information content will be issued depending on the profile of the resident.

Wi-Fi serves as a backbone for cellular networks

There are more and more cases in the world when Wi-Fi becomes the basis for the services of cellular operators. Global telecommunications companies have long considered Wi-Fi as a partner in building infrastructure for smart cities. Public Internet access is an opportunity to reduce the load on cellular network.

In order to digitize the cities, it is necessary to deal with economic feasibility – it is costly to build such infrastructure in non-millionaires. Not so long ago, Google closed Stations, a project to develop free Wi-Fi around the world. It failed to monetize. This task can be solved if the state becomes more active in attracting private business in exchange for future income from the commercial use of digital infrastructure.

In addition, city authorities do not always have time to adapt to technological changes and find experienced personnel to process data and ensure the operation of new systems. Cooperation with businesses will help reduce the shortage of qualified personnel. New programs should also influence the development of infrastructure.

One of the options for implementation is the refusal of mobile operators to pay for access to such resources. Another option that will help develop the infrastructure for smart cities is urban Wi-Fi, using which you do not have to pay for access not only to socially significant, but also to any resources.

These are not insurmountable obstacles, but the next tasks that it is beneficial for the state and business to solve in order to provide the metropolis with ubiquitous Internet access. Only with the help of developed infrastructure will it be possible to spread the digital ecosystem throughout the country and provide citizens with access to personalized services.

DNS, DHCP, IPAM – together they form what we often refer to as DDI. They all work together to manage, assign, and resolve IP addresses and form an important part of any network. we explain below what each of these components are, what they are used for, and why you need them.

Today we start our journey by discussing IP addresses, what they are and why we use them. We will then introduce the DHCP system, how it works and what are its various components. After that, we will discuss the interaction between DNS and DHCP and why it is so important. And we’ll end this article by explaining what DDI is and why it’s so important. And after we’ve finished learning all the basics, we’ll move on to reviewing the multiple versions of EZELINK DDI/IPAM solutions for various industries.

IP addresses are at the very center of the Internet. They uniquely identify each device connected to the network. There is an important distinction to be made between public IP addresses and private IP addresses. The former are those used on devices connected to the public internet. For example, a web server often has a public IP address. The Internet router installed by your ISP in your home also has a public IP address. On the other hand, private IP addresses are the ones we use in home and corporate networks. They must also be unique, but only within a particular network.

Back in the prehistory of the Internet, when the IP protocol was defined, each connected device was manually configured with a separate IP address. We called it static or fixed IP addressing. It was cumbersome but ok since the number of connected hosts was low. As networks (both public and private) grew, it became increasingly difficult to manually configure IP addresses, as the process was error-prone and often resulted in duplicate IP addresses on the network. It took until the early 1990s before a durable solution was introduced in the form of DHCP.

DHCP

The Dynamic Host Configuration Protocol – or DHCP as we commonly call it – was invented to dynamically assign IP addresses and allow connected hosts to connect. DHCP eliminates the need to manually configure IP addresses. DHCP not only configures IP addresses, it can configure most of the connected host’s network settings, such as IP address, subnet mask, name servers, WIND server(s) in the Windows environment, and a few other settings. All parameters are dynamically configured each time the host is started on the network.

No matter what exact parameters are configured by DHCP, the host configuration process is always the same. This is a four step process called DORA which stands for Discovery, Request, Offer and Acknowledgment. Here’s what happens when the host starts.

During the discovery phase, the host sends a broadcast message – this is a message that will be received by any host connected to a network called DHCPDISCOVERY. The message must be transmitted because the host does not currently know the address of the DHCP server.

In the second step, the server responds with a DHCP offer. The offer contains all the host network interface configuration options. Now, this is where things get a little more complicated. Because there can be multiple DHCP servers on a network, a host can receive multiple offers. When this happens, the host will simply select one of the offers and move on to the next step. Which one to choose? He usually chooses the first offer he gets.

In the next step, the host sends a DHCP request. It turns on the offer it chooses and will instruct the server whose offer it decides to proceed with, telling other servers that sent offers they had rejected and that they can release the offered IP addresses.

In the final step, the server sends a DHCP acknowledgment to the host confirming that it has correctly reserved the proposed IP address for that host.

DHCP Client Component

The DHCP configuration information received by the client and used to configure the network interface is invalid forever. In fact, it is leased, not assigned, by the DHCP server. And that lease expires.

It is one of the most important tasks of a DHCP client to ensure that the interface configuration remains valid. It does this by periodically trying to renew the lease before it expires. The update process uses the same DORA sequence. The only difference is that during the discovery phase, the client requests the same IP address that it already has.

Another important function of the DHCP client is the release mechanism. Whenever the client no longer claims its IP address, as it can when it terminates, it will notify the DHCP server to release the IP address so that it can be reused by the server.

DHCP Server Component

As far as a DHCP server is concerned, its main job is to send configuration information to any host that requests it, and have it send unique options to each individual host. IP addresses can be assigned by a DHCP server in one of three ways: dynamic, automatic, or static.

Dynamic allocation assigns a new IP address to each IP address. Automatic allocation is similar, except that the server will keep track of what IP address was assigned to each host and will try to assign it the same address the next time it connects.

And finally, with manual allocation, the administrator must manually associate a specific host, identified by its MAC address, with a specific IP address. This is also called a DHCP reservation because it reserves a specific address for a specific host.

Interaction between DHCP and DNS

The Domain Name Service – or DNS – is used to map hostnames to IP addresses. In a private network using dynamic DHCP allocation, there is often some integration between DNS and DHCP. So DNS always knows the current IP address of each host.

This is why many DHCP servers also include a DNS server. This applies, for example, to the Microsoft DHCP server, which is fully integrated with the DNS server.

DDI (DNS, DHCP, IPAM)

DDI is an acronym for DHCP, DNS and IPAM or IP address management. While we have not yet discussed the latter. IPAM refers to any software used to manage IP addresses. Such systems can typically be used to manage both DHCP-assigned addresses and statically-assigned addresses that are manually configured on hosts.

With the tight integration that is required between the three, it is quite normal that many vendors have three products built into each other, or that they offer all three products separately.

EZELINK 5 versions of DDI/IPAM Systems

Every DDI Solution of EZELINK can be used with all 3 features of (DNS, DHCP, IPAM) or as an individual product model of (EZE-DNS, EZE-DHCP and EZE-IPAM) in a standalone and can be inetgrated with many popular DNS and DCHP servers, such as the ones we find on Windows and Linux.

EZELINK Platinum Network DDI

EZELINK Platinum DDI is one of the best in network management. The product conist of some of the best tools for helping administrators. It allows you to use built-in DHCP and DNS servers making it a complete DDI system, and the software can also communicate with DHCP and DNS server from Microsoft and Cisco so you don’t have to replace all your infrastructures.

The software allows you to use several distribution methods for IP addresses. For example, you can use reservations for servers and other equipment and dynamically allocated addresses for workstations. Everything is fully integrated into DNS. In addition, a configuration wizard is included to assist in configuring DHCP scopes.

EZELINK Platinum Network DDI uses user accounts with different access levels. You can grant only partial access to some junior administrators, or allow managers to view reports. There is also a good logging system that records all changes with a timestamp and the username of the operator who made the changes. This can help with compliance issues.

EZELINK Large Enterprise DDI

EZELINK Large Enterprise DDI is one of the industry leaders in this field. The address management is best suited for large corporations with a network management team. The IPAM system is actually a complete DDI system that includes DHCP and DNS. It can also communicate with DHCP and DNS servers from Microsoft.

It’s a is a dual stack system, which means it can work with both IPv4 and IPv6 at the same time. It’s really a great tool to use when moving from one to the other. From a security point of view, the system has workflows and approval schemes, as well as user accounts with hierarchical rights.

The system uses network templates. They allow the administrator to use information layouts that prevent important tasks from being overlooked and that all important data is present. In a nutshell, the EZELINK Large Enterprise IPAM system automates as many network administration tasks as possible. As a result, problems caused by human error are less common. It is a premium package so you can expect premium prices, but if you manage a large network it’s worth the investment. You can visit our DDI Solution page for more information.

EZELINK Centralized DDI

EZELINK Centralized DDI is ideal for management of the IP address space. It can handle both IPv4 and IPv6 addresses. The built-in IP manager software helps network administrators determine whether an IP address is currently available or not. The IP Address Manager tool periodically scans the subnets and updates the availability status of the IP addresses on each subnet.

Users can use the IP Address Manager tools to quickly and easily check if a particular IP address is reserved or available. The tool accepts multiple subnet inputs, which helps when scanning the entire network to get the status of all IP addresses.

Request for a free demo of the product, with limited to one subnet. It is enough to give the product a trial run. It might even be all you need if you run a smaller network. Visit the EZELINK website for more information.

EZELINK SME IPAM & DHCP

EZELINK SME IPAM & DHCP is better suited for small to medium networks. Like other SME systems, it has templates for automating routine tasks. It also comes with excellent standard reports. And if you don’t find existing templates or reports to your liking, you can customize them to your liking.

SME IPAM & DHCP allows managers to track key resource usage. It also has snooping features that help you manage your DHCP usage efficiently. Security-wise, this is great, as it also includes the ability to identify external addresses and isolate rogue devices. This is a pretty unique feature that you won’t find on other systems. It shows how EZELINK treats security like it does IPAM and has safeguards built into the system.

New nodes can be centrally integrated into the network through the DDI user interface, and per-node usage comparison is also simplified with efficient MAC address records as well as IP address tracking

EZELINK IP Manager

EZELINK IP Manager is a great DDI kit is an automated Internet-based IPv4/IPv6 address management software (IPAM). It has powerful network discovery features and offers search and filter functions for networks and host by resolving equivalent expressions in the Internet search engine. This allows you to find information that administrators often require easily and quickly.”

In concrete terms, it’s a great system, especially for small businesses that might not be able to afford large solutions like Centralized DDI and SME IPAM & DHCP. It includes all the features a network administrator could want with minimal price. And it also has some unique features like subnet calculator and IP address plan builder. This is definitely a package worth looking into.

Conclusion

EZELINK has a big range of multiple versions of DDI platform suited to every organization as per heir requirements and features. The above five are the ones we think will cover most of the industry business requirements for large and small networks. But if you feel you need a turnkey solution EZELINK R&D team can be a big help to deliver customized solution as per your requirements .

https://ezelink.com/i/blog/wi-fi-6e-extends-the-wi-fi-6-capabilities-into-the-6-ghz-domain/

With more than 1,200 MHz of unlicensed spectrum available, more than triple the number of high-bandwidth channels available, and freedom from supporting legacy devices, Wi-Fi 6E promises a massive leap in
wireless performance and efficiency.

The WiFi 6E standard is relatively recent. How is it different from the previous generation?

WiFi 6E is a new standard based on WiFi 6. It differs from its predecessor with 14 new 80 MHz channels, plus 7 160 MHz channels, as well as the ability to operate in the 6 GHz band. All this provides greater bandwidth, the ability to support more devices and transmit a large amount of data at the same time.

How will these differences affect the Dubai based business? Who will need this standard first? If the company has a small office, does it need such WiFi?

https://g.co/kgs/7GW5vR

The new standard is needed primarily where the density of devices is high. If employees in your office sit close to each other, if each of them has several devices connected to the Internet at the same time, if they have to work with a large amount of information, WiFi 6E will make work more comfortable even in a small organization with a small number of employees. Not to mention enterprises with a large number of equipment, sensors and other devices connected by IoT.

Wi-Fi 6E for 8K video streaming, online gaming, and virtual reality

But the new format will also be relevant in large rooms or spaces: these are stadiums, concert and exhibition halls: in all these places there are many visitors, each of whom has a device connected to the Internet, and WiFi 6E allows them to work without disturbing each other friend.

Does the Dubai consumer need 6E at all? Will a person who mostly just watches series online notice a difference?

Technology is constantly evolving, and Dubai is leading for the front. Video resolution is getting higher, cloud gaming is gaining popularity, and the number of devices owned by the average consumer is not decreasing. Dubai needed WiFi 6E for multiple category of consumers like gamers who want to play without delay (and not only on a computer or console, but also in virtual reality glasses), and ordinary consumers who want to watch Netflix shows on a tablet while lying on the couch after work. And so as not to interfere with other people in the apartment. The same thing is critically important for Dubai business and consumer: high speed, good communication quality and absence of interference. In homes and offices, WiFi 6E helps make this happen.

Is the UAE Ready for Wi-Fi 6(E)?

One of the lessons learned during the recent pandemic is that companies are changing how they do business. For example, employees may not need to report to the office or campus. Instead, they may prefer to work remotely, either part-time or full-time, but expect the same company’s enterprise Wi-Fi experience as well. As a result, the company is not just in one building but distributed everywhere employees work. We now have an infinite enterprise. Wi-Fi 6 and Wi-Fi 6E are part of a wireless paradigm shift toward infinitely distributed connectivity. Corporate organizations need connectivity for anyone anywhere with devices or applications to ensure productivity on an ongoing basis.

Why is 6E even better than Wi-Fi 6?

Technically, there is no theoretical performance difference between Wi-Fi6 and Wi-Fi6E when it comes to speed. Both are based on the same IEEE802.1ax-2020 standard. The only difference is one operates in the legacy 2.4GHz and 5GHz band, and Wi-Fi 6E operates in the newly opened 6GHz band.

However, Wi-Fi6E will more likely be faster in practice because the 6GHz frequency spectrum offers more Wide-Band channels (HT-80 and HT160) and no interference from legacy (802.11a/n/ac) devices.

80MHz and 160MHz channels were available in previous generations (802.11ac and 802.11ax in the 5GHz band) but were not required and were often not supported or used due to lack of spectrum availability.

The 6 GHz band opens a contiguous spectrum sufficient to take full advantage of these wide channels and will be part of most 6 GHz implementations to take advantage of the highest multi-Gbps throughput. For example, a 2×2 802.11ax module would offer a 2.4 Gbps maximum theoretical data rate. The results would be better and close to the theoretical max in 6GHz frequency.

1200 MHz of contiguous spectrum in 6GHz enables 7 new 160 MHz channels and 14 new 80 MHz channels. Network administrators can enable the widespread use of wider channels without the risk of interference from overlapping channels. Deployment of a wider channel will unlock multi-gigabit Wi-Fi speeds for end-users.

Is the transition to 6E inevitable? And what will happen after it?

Dubai is the city adopting the change of latest technologies quickly and Wi-Fi 6E sooner or later will be generally accepted – it’s only a matter of time. As for the new communication standards that will replace 6E, today the industry is working on a new generation of WiFi technologies – WiFi 7 (IEEE 802.11be).

Help carriers upgrade their existing LTE networks , generate additional Trusted Wireless Access ( TWAG ) revenues and accelerate 5G deployments.

Gateway operates on the same 5G band (up to 6 GHz) that operators will use to upgrade their LTE networks , which will expand coverage for trusted wireless access and enhanced mobile broadband services.

The TWAG market is projected to grow by about 50% from 18.5 million to 27.5 million households by 2022. Operators are increasingly using TWAG technologies to grow their business and monetize new services. Wireless networks will play a critical role in supporting new broadband access services, with a 16% market share of TWAG by 2022.

The EZELINK TWAG solution will help operators gain significant value from this growing market segment. This solution is a hardware device that can be easily installed indoors and connected wirelessly to a mobile network.

The gateway provides gigabit speeds to home subscribers based on the 3GPP wireless New Radio (NR) standard. Using carrier aggregation, the gateway improves network performance and reliability by selecting the most reliable 4G and 5G signals.

Wi-Fi in the office is convenient, but not always secure Office Wi-Fi can be a weak point in your security system. Almost every office has its own Guest wifi solutions, and sometimes there is more than one. In the modern world, it is difficult to do without wireless Internet: few people want to connect laptops using a cable, and with smartphones and tablets this is often completely impossible. However, a wireless network can be a weak point in your IT infrastructure.

Password Guessing

Not all companies come up with a complex and unique password for their wireless network. Disable the broadcast of the network name – and even less. And only those who limit the signal power in order to exclude the possibility of connecting to the network from the outside are generally few. Thus, nothing prevents an attacker from locating near the office and trying to penetrate the corporate network via Enterprise wifi solutions. After all, it can take only a few seconds to brute force simple passwords. Hacking complex combinations will take more time, but if you do not change your password for a long time, then the attacker has nowhere to rush. However, this is not always necessary – in the case of some routers, an attacker can also take advantage of “holes” in the firmware.

Enterprise WiFi Solution

Vulnerabilities are constantly discovered in network equipment that allow attackers to attack the network bypassing passwords and other protective mechanisms of your Wifi6 wireless solutions router. In some cases, thanks to this, they can obtain superuser rights on the device and then dispose of them at their discretion. Patches for such vulnerabilities are released regularly enough. The only trouble is that many organizations are in no hurry to install them in a timely manner.

Office WiFi Solutions

Many companies use different Outdoor wifi solutions networks for employees and guests. This is a reasonable measure: on the one hand, clients and other visitors to the office can connect to the Internet, on the other hand, they will not have access to the corporate network and internal resources of the company. However, guest Wi-Fi can also work against you.

Getting a password for a guest Wi-Fi is easy enough – that’s his idea. At the same time, in some cases – with incorrect configuration of network policies – through the guest network, you can get access to individual elements of the corporate infrastructure. For example, attackers can often get to printers in this way.

Even with proper configuration of guest Wi-Fi, your employees can unwittingly put you in jeopardy. Let’s say one of them wanted to go to a site that is denied access by corporate policies. Without thinking twice, he connects a laptop or smartphone with work data to a visitor hotspot. If attackers connect to the network at this moment, they will be able to launch a MitM attack and infect the employee’s computer.

WiFi Vulnerabilities

How to make office Wi-Fi less vulnerable?
Ditching Wifi solution for safety reasons is like ditching your car because you risk getting into an accident. We believe it is better to be smart about organizing and configuring your network:

Update the firmware of access points: manufacturers are constantly patching existing vulnerabilities in them.
Set a unique, long, complex, and non-obvious password for Hotel wifi solution access. It will be enough for your employees to enter it once on each device, and for cybercriminals, network hacking will become much more difficult.
Limit signal strength so that your network is not available outside the office. Better to hide the name of the network altogether – this will make it harder to find. By the way, it is better to use an unobvious name too (at least without the name of the router model): otherwise, it will be easier for attackers to find a suitable vulnerability.

Office Cloud Managed WiFi

Do not give users of the guest network access to internal Cloud managed wifi solutions company resources. You may have to deny your visitors some conveniences (like the ability to print a document on your printer), but you will significantly reduce the risk of data leakage.

Use reliable Office wifi security solutions. In this case, attackers, even if they get into your network, will not be able to do significant harm to workstations and servers.

Today wi-fi has become an integral part of any mass event. The bulk of the participants are business people who must constantly be in touch, have access to corporate resources and the Internet. Therefore, Wi-Fi should not only “shine”, but also “work”.

Some of the major aspects you need to consider for any event wi-fi solution:

Event WiFi Solutions

A large number of users (up to several thousand) are concentrated in a limited area. Often, such events have a main conference room, which brings together almost all participants (plus speakers, organizers) who need Internet access. You also need to organize Wi-Fi in other rooms with a lower density of users.

Connecting to the network should be simple. Those. to connect to a wireless network, the participant does not have to perform any settings on his mobile device (setting the type of authentication / encryption).

Festival WiFi Solution

Festival Wi-Fi Solution users should be divided into groups (participant, presenter, organizer). Each group has corresponding connection policies (speed limits, services, directions).

Wi-Fi users should be divided into groups (participant, presenter, organizer). Each group has corresponding connection policies (speed limits, services, directions).

The system should keep statistics about users: the total number of associated users, their distribution by AP, the average user traffic. It is also useful for a wireless network administrator to have the operation logs of the radio environment monitoring system (for the presence of “alien” APs and wireless attacks).

Outdoor WiFi Solutions

To meet the above requirements, as well as to fulfill the main task of event organizers (Wi-Fi must “work”), wireless installers must adhere to some recommendations. These rules are not a dogma and are not described in any international standards for organizing Outdoor Wi-Fi Solution networks at public events. Variations are also possible depending on the configuration of the premises (area, type of partitions: open space, light partitions, brick walls, etc.), the total number of participants, their distribution in the halls, requirements for access speed. Everything described below is based on the experience of installing such systems by the specialists of EZELINK.

A little about our experience. In all projects we use the inhouse manufactured equipment. Since 2004, we have been participating in the Wi-Fi installation at the annual events and exhibitions in Dubai. More than 20, 000 people gather at the conference and actively use Wi-Fi.

Dubai Outdoor Events

EZELINK also organized Wi-Fi at the Rugby7 (event WiFi Rental), Interpol, KISS, Dua Lipa events in Dubai. Let’s describe the basic principles of Wi-Fi network installation using the example of the Emirates Rugby Sevens Annual Sports event.

Before the start of the event, our specialists went to the site. According to the requirements of the organizers, the total number of simultaneous connections is 3,000. All users during the event were spreader over 3 sq km area including, retail outlets, recreation areas, commentary box, contractors, staff and guests. For normal operation of the AP (and the speed per client was slightly less than 3 Mbps), we believe that each AP radio should have no more than 35 simultaneously working clients. From the experience of past installations, it can be seen that about 30% of clients work at 5 GHz and 70% at 2.4 GHz, we get 210 g / n Wi-Fi clients and 90 a / n Wi-Fi clients.

Multiple SSIDs were organized for all participants: broadcasted in the 2.4 GHz band and 5 GHz band. Dedicated SSIDs were allocated for presenters, staff and hosts. The role (policy) was assigned to the client based on the results of his authentication.

When registering each Wi-Fi participant, he was given a PIN-code. The participant connected to the open SSID, then, when the Internet browser was opened, he was redirected to the registration WEB page, where he entered his PIN-code. For all PIN-codes in the system, users were created who were assigned the corresponding role. Thus, all participants connected to any of SSID (depending on the selected range) and received a role according to the requirements of the organizers.

Wi-Fi Access Points were located according to preliminary survey at a height of no more than 3 m above the floor. This was done to increase the coverage area of ​​the AP (due to the radio signal conflict of mobile devices of the conference participants). Wi-Fi clients who were in the coverage area of ​​one AP saw neighboring APs with a noticeably lower signal level (by 10-15 dB) and do not try to “jump” on them, which increases the speed of their work by reducing service traffic. In addition, local coverage areas allow channel reuse in the 2.4 GHz band.

Event WiFi Access Points

By placing the AP on the ceiling (high on the walls) and without limiting the radiation power, we got large coverage areas that was overlap. In the case when there was more than three APs operating at a frequency of 2.4 GHz in the room (as in our case, there were many of them in the stadiums), using the same frequency channels, we got a strong mutual influence and, as a result, an increase in bandwidth.

Since there were only three non-overlapping channels in the 2.4 GHz band, and in the stadium alone, 39 APs were used, the level of the radiated power of the APs in this range was manually underestimated. In a practical way, it was determined that the optimal level is 13 dBm (20%).

In the 5 GHz range, the number of non-overlapping channels were 12. 8 and allowed to be used indoors without obtaining frequency permission (channels 36 – 64). In our configuration, only two channels were reused, so the transmit power was left at 100%.

AP operating modes settings system has a Minimum Transmit Rate (MTR) parameter. On all APs, it was set to 24 Mbps. The 802.11 standard contains a procedure for switching a Wi-Fi client to a lower speed when receiving conditions deteriorate – Dynamic Rate Shifting (DRS). The client reduces the modulation rate, which decreases the operating speed, and increases the sensitivity threshold. In our case, this could have been lead to serious problems. Since each client makes the decision on roaming individually, many (mobile wifi for festivals )mobile devices would try with their last bit of strength to cling to the AP with which they were originally associated. In this case, the speed could drop to a minimum (1 Mbps) and there was a large number of retransmits.

Event WiFi Advantages

MTR does not allow the Wi-Fi clients to slow down below the specified speed. Therefore, it cannot reduce the modulation rate below a certain value, and accordingly increase the sensitivity threshold. MTR 24 Mbps limits modulation to 16 QAM. Due to this, clients will not “see” distant APs and try to associate with them, and when switching to another AP, they will make the decision about roaming faster.

We disabled 802.11b support for all APs operating in the 2.4 GHz band. Accordingly, only 802.11g / n clients were supported. This restricted our network from “slow” and “overly sensitive” clients that could create the problems described above.

In 2020, the world will spend $ 124 billion on the smart city industry. Citizens can already receive documents, make appointments with doctors and pay fines online.

In the future, a lot in smart cities will happen automatically: the application of the polyclinic based on the data from the fitness bracelet will register for a medical examination, and the city services will clear the trash can according to the data from the sensors. Artificial intelligence will identify people with weapons in the crowd, and the fire brigade will go to the scene before the call of eyewitnesses – on a signal from video cameras.

Wi-Fi is an integral part of the digital infrastructure that is being deployed in major cities around the world. Most often, its development is hampered by the lack of investment and the unpreparedness of cities for technological changes.

Tourists and startups choose Wi-Fi

The rise of Wi-Fi could turn cities into technology hubs – fast public internet is attracting young entrepreneurs. Wi-Fi also affects tourist activity. The quality of public Wi-Fi is one of the main factors in the satisfaction of tourists. For these reasons, in Taiwan, two years after the launch of free Wi-Fi for citizens, guests of the island were given free access to the public network.

Some countries use free Wi-Fi as one of the gentrification tools. Together with other measures – the creation of public spaces, subsidies for small businesses – this helps to increase the attractiveness of the sleeping areas.

Now the city authorities and businesses are investing in it, which makes money on advertising in the networks. But in the future, operators of “home” Wi-Fi may join the creation of public networks. Companies are implementing projects in which city residents provide a small portion of their home Wi-Fi power to urban networks, and users switch between these points, moving between houses.

By the way, US residents with free access to such points for 60 days to help people stay connected during the coronavirus pandemic.

Wi-Fi manages road traffic and utilities

Wi-Fi allows you to plan urban infrastructure based on anonymized aggregated data. Like many Internet resources, the network can predictably determine the user’s approximate age, gender, and interests. And if in the district, for example, there are many young people with children, the authorities can plan the construction of new kindergartens.

One of the main areas that Wi-Fi can transform is transportation. Networked video cameras, touch sensors, smart toll terminals and other gadgets help analyze public transport traffic and suggest new interchanges, adjust the number of buses, move stops, etc.

In Singapore, Wi-Fi is available almost everywhere. It is he who is used by city services to manage the life of the city. To control traffic on the roads, an intelligent transportation system operates here , which relies not only on a network of gadgets installed on the roads, but also on sensors, cameras and GPS devices that are in taxis.

Moreover, the system makes it possible to adapt the urban environment for people with disabilities – for example, it automatically identifies them at crossings and increases the green light time.

Wi-Fi is also powered by other services that enable cities to collect big data, reduce costs and improve service efficiency – smart parking and smart lighting, smart video surveillance, and automatic water and power supplies.

Advantages over 802.11ac

• Minimize wireless connection failures
• 3x speed increase
• Ability to transfer significantly more data
• Reducing battery consumption by improving energy efficiency
• Improvements for 2.4 GHz band
• Integration with 5G networks

Since the standard is still being certified, the market has not yet presented hardware for Wi-Fi 6. However, many large manufacturers of network equipment, including EZELINK, have already presented a new generation of access points based on the latest standard, which will soon appear in the Sales. Ideal for large branch offices with a large number of employees, where it is necessary to process a huge amount of data from dozens or hundreds of workplaces every day.

The first wireless networks of the 802.11 standard could provide only 11 Mbps, and even then these 11 megabits were shared among all devices in the network segment. The 802.11g standard raised this figure to 54 Mbps, at the same time the first timid attempts to look beyond the 100 Mbps mark began, however, which did not lead to the emergence of a single standard. Meanwhile, the popularity of Wi-Fi grew and the 2.4 GHz band gradually became narrow, so in 2009, with the advent of the 802.11n standard, an attempt was made to fully master the 5 GHz band, but only in 2013 with the ratification of 802.11ac this frequency segment began to be used en masse. This generation of Wi-Fi is commonly referred to as the fifth generation.

The fifth generation was able to achieve and even surpass the performance of wired gigabit Ethernet, but to provide really high speeds required the use of transceiver-antenna formulas from 4 × 4 and the principles of MU-MIMO. And only the sixth generation of Wi-Fi has become what could be called a truly effective wireless network: even at CES 2018, prototypes of 802.11ax devices capable of developing up to 11 Gbps were demonstrated. This is reflected even in terms: Wi-Fi 6E and HEW (High-Efficiency Wireless), in both cases, the letter E means “efficiency”.

The final version of the IEEE 802.11ax specifications was presented last year and approved in September this year. Nevertheless, despite unification and standardization, the leading manufacturers of wireless equipment have their own vision of Wi-Fi 6. EZELINK stands out as company is well aware that the IT world has changed a lot since the introduction of 802.11ac, and old technologies are poorly suited to implement a number of scenarios, such as the active use of augmented reality, modern video surveillance systems with high-definition cameras, or the organization of large networks in trade and industry.

In addition, EZELINK actively takes into account the fact that many companies, applications and services have migrated or are migrating to the clouds today, and reliable and stable communication is essential for high-quality work with cloud systems. Therefore, in its Wi-Fi 6 devices and systems, EZELINK implements the principle of “100 Mbps to everyone” – of course, this is not yet 1 Gbps, as in wired GbE, but there are more and more clients in modern networks, and not even all of they generally have the ability to wired connections, for example, various IoT devices, such as “smart price tags” in large supermarkets.

The company follows the standard quite creatively: so, realizing that the 5 GHz band will soon become very tight, in its implementation of Wi-Fi 6+ EZELINK proposes the use of a new, additional 6 GHz band, which has not yet been mastered en masse by anyone. This will not affect the performance of devices in the 5 GHz range in any way, since a separate, new radio module with its own antennas optimized for this range will be used for 6 GHz.

But even the old features implemented in previous standards may function differently in Wi-Fi 6. So, even channels with a width of 20 MHz can be cut into subcarriers in steps of up to 2 MHz, which means that several stations can broadcast in the allotted time slot, which in general will increase the efficiency of the network and reduce delays.

The new access points have 16 receiving antennas, the points themselves are optimized taking into account the experience gained during the modernization of WiMAX and 5G networks. In addition, the antennas at these points are new, made using the proprietary Smart Antenna technology, due to which they are more resistant to signal interference. Supports up to 12 spatial streams, which is 1.5 times higher than solutions from other manufacturers, and the number of spatial streams with a width of 160 MHz can reach eight. The tests carried out have shown that EZELINK is ahead of devices from other manufacturers in terms of signal-to-noise ratio (SNR).

It is also worth mentioning the IoT expansion function – in the new access points there will be two slots in which you can install expansion modules, for example, with ZigBee support or even specialized ones developed in cooperation with any client in need of a certain IoT service. For example, it could be an RFID module for dealing with the increasingly popular “smart” price tags in large retail supermarkets. Also, in some models, one more expansion module can be connected using a USB port.

One cannot ignore the fact that all of EZELINK’s new Wi-Fi 6 access points use Software Defined Radio (SDR). This automatically provides them with increased flexibility – depending on the future scenario of operation, the administrator of the future network can fine-tune any of the three available radio modules or all three if necessary. For example, two modules can work as client modules, and the third one can act as a scanner of the radio environment, monitoring its state and transmitting the corresponding telemetry to the cloud control center. Or, if this particular point has few clients, but they are demanding, you can configure the link aggregation so that each client is allocated a wider bandwidth, for example, 80 instead of 20 MHz.

EZELINK’s implementation of MU-MIMO in new access points is smart: it simultaneously tries to maximize the entire antenna complex, but at the same time use it smartly – the priority will be more powerful and more bandwidth-intensive devices, for example, industrial or laboratory AR- systems with their heavy traffic volumes. Physically, EZELINK’s new access points can operate at a speed of 10 Gb/sec, in fact, with an efficiency of about 80%, this means approximately 8 Gb/sec, the results of testing a message showed 8.37 Gb/sec; Of course, this does not mean that each client will receive the same amount, but he will receive his guaranteed 100 Mbit/sec.

EZELINK sees Wi-Fi 6 not just as a replacement for Wi-Fi 5, but as a foundation for the functioning of business processes. Naturally, the “foundation” status imposes special requirements, including increased reliability and unified controls. The usual response to network problems and their subsequent “manual” resolution is not enough – you need proactive controls to prevent the very occurrence of problems that could affect the workflow. This requires modern technologies, including predictive analytics and machine learning tools, and EZELINK has such technologies, moreover, integrated into a single complex.

EZELINK reliable and high-quality equipment with extensive research & development in wireless technologies delivering successful projects in every industry irrespective of their size and complexity. Our specialists have the appropriate education, knowledge and experience, so you can rely on us.

We are beginning to make requirements for the devices, be it a laptop, tablet computer or any other specialized equipment. That is why more and more often there is a need for modernization or implementation of wireless networks, which can exist in parallel or completely replace the wired network.

"A full-fledged transition to a wireless network has become possible thanks to the EZELINK Turnkey Wi-Fi Solutions, which are now fully capable of meeting the requirements for corporate, commercial or industrial networks."

AMAN KHAN, PROJECTS HEAD

Current stage of development of wireless technologies allows using Wi-Fi networks to solve almost any problem of building an access network, be it an office, hotel, shopping center or cottage village. When considering the implementation of an external (street) Wi-Fi network project, it is worth paying attention to the fact that in the absence of a large demand for Wi-Fi at the moment, it is enough to introduce one or more access points instead of covering the entire facility with wireless coverage. And then, as requests come in, gradually expand your business. This method of developing a wireless network will reduce the likelihood of costs and the size of the initial investment.

Wi-Fi Solutions for Small Businesses

Small business solutions are simple, cost effective and fast to install. Wireless access in such solutions is provided for access to the internal network and the Internet. Support for voice and video communications, as well as streaming data, is significantly limited. Typically, the number of access points in these solutions does not exceed 4-5, with about 6-8 clients connected to each. Such configurations do not require the use of hardware controllers; all access points are configured separately. To manage the network, it is necessary to carry out identical manipulations with each point separately, which requires higher qualifications of IT personnel and reduces the functionality of the system as a whole.

Corporate Solutions

In installations of this level, hardware controllers of wireless Wi-Fi networks are always used. Solutions of this class assume the use of up to 3000 access points, and support the simultaneous operation of up to 30,000 client devices. When using specialized radio sensors and access points with the function of monitoring the radio broadcast, a system for determining the location of subscribers, sources of interference and intruders posing a threat to the security of the network can be implemented. At the same time, the system has the ability to self-repair: in the event of interference, a dynamic selection of the channel least affected by the interference occurs. Fail-over mechanisms are implemented. If an access point fails, its clients are intercepted by neighboring access points without losing the connection.

Hotels, Restaurants and Cafes

The specificity of Wi-Fi solutions for hotels, hotels, restaurants involves the use of a wireless network for Internet access, e-mail, VoIP telephony and video communication. Such schemes do not require the implementation of client roaming functions without breaking the connection, since the main traffic flow comes from fixed points. A software controller can be used to configure and monitor access points. To ensure the security of guests’ data and to facilitate the configuration of client devices, WPA2 password-based encryption is used, since this excludes the possibility of eavesdropping on the air and intercepting confidential information. For the convenience of administration and sale of Internet access services via Wi-Fi, you can provide a Personal Account for each mobile subscriber.

Education

In addition to commercial use, the trend of deploying Wi-Fi networks in educational institutions is gaining momentum. In schools and universities, wireless access from tablet PCs completely translates the entire educational process into an interactive environment, which significantly improves the quality and level of education. To attend lectures, it is not necessary to be physically in the classroom; the issue of access to information carriers is being resolved: paper manuals, libraries, timetables. Interaction between teacher and student becomes available anywhere in the world.

Healthcare

Using Wi-Fi in medicine means instant access to the most up-to-date information from the Internet, any reference manuals, the ability to write prescriptions with one touch of the screen, storage and backup of all patient records on servers, etc.

Wireless Solutions For Telecom Operators

The main problem when deploying a cellular network is the limited bandwidth of each cell. All the speed available to the base station is divided between the subscribers. To increase the speed, operators are trying to reduce the number of subscribers, reducing the coverage area of ​​each cell. This entails unreasonably high costs for increasing the number of expensive base stations to cover the same area. In this case, Wi-Fi is used. Cheap Wi-Fi hotspots provide Internet access exactly where you need it most. Subscribers’ voice calls are made through the existing GSM and 3G networks. There is no need to deploy additional 3G base stations. In another scenario, Wi-Fi is deployed in conjunction with short-range cells (pico and femto cells) in places with the highest subscriber density, to reduce the load on cellular base stations.

In addition, the vast majority of mobile devices are equipped with Wi-Fi, even entry-level tablets and e-readers that do not have any other wireless communications. All these devices can be connected via Wi-Fi to the operator’s networks, expanding the subscriber base and increasing the economic feasibility of deploying such networks. The same situation is observed in 4G networks (WiMAX / LTE). These technologies are often used as a backbone to deliver traffic to specific points. This traffic is then distributed locally over the Wi-Fi network. This process is called offload. At the same time, the subscriber of the cellular network continues to receive voice calls and SMS through the cellular network, and all Internet traffic goes through Wi-Fi. At the same time, Internet telephony and video conferencing services such as Skype and Lync remain available. Billing for Wi-Fi at local points can be organized in any available way: through payment terminals, paid SMS with temporary passwords, etc.

BYOD (Bring Your Own Device)

The BYOD concept is a security policy under which company employees are allowed to bring their own portable devices (laptops, tablets, communicators) to the workplace and use these devices to access the company’s privileged data and services. The term is also used to describe the same practice in educational institutions where students use personal devices for educational purposes. With this approach, all corporate security policies are implemented, the local network remains protected from possible threats. It is more convenient for staff and students to work from their personal devices, and this practice has become a general trend. Our task is to design and configure a Wi-Fi network in accordance with the modern needs of the Customer.

High Level of Security

Wi-Fi uses sophisticated encryption methods that cannot be bypassed or “broken” with modern computing power. Access is provided both by password and by a security certificate. Logging into a wireless Wi-Fi network is as secure as connecting to a corporate switch port.

Scalability

Not every implementation requires further scalability (e.g. hotels, restaurants, cafes). But if you are faced with the task of building a scalable wireless network, then the main point is the choice of the manufacturer and the line of access points. Not all access points scale from a standalone access point to a cloud of lightweight access points managed by a Wi-Fi controller. In scalable wireless networks, the first step is to install and configure multiple access points. The development of the company and the increase in needs will not entail a complete replacement of equipment. It will only be necessary to update the software (firmware) on the existing access points and add wireless components.

Seamless Roaming

To implement voice (VoIP) or video communication, the corporate infrastructure uses fast roaming mechanisms (analogous to handover in cellular networks). The Wi-Fi wireless network controller transfers service to mobile subscribers as they move from one access point to another without delays or packet loss.

Automatic control and management of radio resources of the system. The WLAN controller performs dynamic redistribution of frequency channels and transmitter powers of access points according to specified algorithms. This reduces the level of interference created by neighboring points. Mechanisms of redundancy of access points are implemented – if one of the devices fails, the neighboring points increase the power and “intercept” clients, the service does not suffer.

Protection of radio air from interference and malicious clients. Standard Wi-Fi wireless LAN equipment is not capable of detecting interference from non-IEEE 802.11 devices. The task of monitoring the radio broadcast falls on access points with an additional spectrum analysis function, or specialized radio sensors that complement the infrastructure of a wireless Wi-Fi network. In some cases, this role is assumed by access points that are switched to analysis mode and do not serve clients. After detecting interference, the system rebuilds the channel plan of the access points. Moreover, so that channels adjacent to interference are assigned to access points that are as distant as possible from their sources. In addition, the system allows you to record attempts to “jam” the network and block malicious attempts to guess the access password.

Determining the location of devices. Dedicated services running on the Wi-Fi controller allow you to determine the location of emitters based on the signal strength received by multiple access points. These include both client gadgets and computers, and sources of interference (microwave ovens, cameras), malicious devices (“jammers”, access points – twins). The system determines their location and displays them on the floor plan. There are several options for the implementation of such systems, their accuracy is about 3-5 meters. Location data can be used to collect statistics, as well as to prohibit the use of mobile devices in certain areas on the building map, for example, meeting rooms or bathrooms.

Consistently high access speed. To ensure high speeds of access to the network, it is necessary to fulfill a number of factors, the main of which remains the competent design of the WLAN. The job of the surveyor or point placement engineer is to provide continuous coverage throughout the building. In this case, the system must be configured in such a way as not to accept connections from clients outside of a stable connection. In this case, the network will not be overloaded with re-sending packets, and all clients will be provided with a guaranteed connection speed, regardless of the load of each.

Increased user loyalty. In the service sector (hotels, hotels, hostels, restaurants, cafes, bars, business centers, shopping centers and malls, etc.), the provision of free Wi-Fi Internet access services significantly affects the client’s attitude to the service provider and increases “stardom”. For some potential customers, being able to access the internet is critical. In large malls, shoppers receive additional information and product reviews online and are more likely to shop. In addition, on the basis of free access to a wireless Wi-Fi network, an interactive product catalog can be implemented on the web portal platform, as well as a shopping cart, contextual advertising, an interactive shopping center scheme, and other services.

Web Authentication

Popular solution for hotels, airport terminals, shopping centers. Its essence is that a mobile subscriber connects to a Wi-Fi network without a password, opens an Internet browser and enters an arbitrary URL. The authorization system automatically redirects him to the authentication page, where he can enter a username and password. After successful input, the user gains access to the Internet. Web authentication systems are also popular in corporate wireless Wi-Fi networks, where data from Active Directory are used as login and password.

Guest portal for hot spots. Often in places with open access, before getting on the Internet, users go to the service provider’s page (restaurant, store, mobile operator, etc.). From where, after viewing the mandatory advertisements, the client is redirected to the Internet. This approach is similar to web authentication, but does not require a username / password pair. The portal is a web page on the basis of which any web services, statistics collection services, connection duration, etc. can be implemented. It should be noted that advertising covers the costs of clients’ Internet access, which, among other things, may be limited in speed / time / volume, etc.

Quality of Service (QoS)

The Quality of Service (QoS) mechanism classifies traffic by type and importance, sending high priority data packets first. Without this mechanism, it is impossible to simultaneously pass large amounts of simple data and voice communication (VoIP – Voiceover Internet Protocol) or video conferencing over the network. In the absence of this technology, the connection “croaks”, is interrupted, the image of the interlocutor is fragmented and covered with “squares”.

Designing and installing Wi-Fi wireless networks is a complex engineering task, in the solution of which specialists from several directions take part. In order for the network to meet all customer requirements and provide a reliable service, at all stages of implementation, the requirements for the placement of access points, antenna orientation, installation of SCS for powering access points via PoE and connections with switches are strictly met. Equipment tuning done by engineers who have knowledge of the technique and physics of radio wave propagation, as well as have experience with the equipment installation. Otherwise, you may be sold a large amount of equipment that individually meets all the requirements, but installed in such a way that it is a “pile” of expensive non-functioning “hardware”. Our specialists have the appropriate education, knowledge and experience, and are also certified for industry leading standards, so you can rely on us. This is evidenced by EZELINK, successful projects and the confirmed qualifications of our engineers.

To implement them, broadband access channels are required, which telecom operators and service providers must be prepared to provide. At the same time, convergence occurs in telecommunications, which is widely discussed at the turn of the 20th and 21st centuries - this is the unification of networks, services and access equipment (with appropriate security and quality assurance). Let's take a quick look at some of the hardware and technology trends that will shape the near future of info telecommunications. First of all modern integrated components, microcircuits and their specialized sets (chipsets) do not cease to amaze with their capabilities. Communication equipment based on modern electronic components already today makes it possible to provide device interaction speeds of more than 100 Gbps on backbone lines, and from 1.3 to 7 Gbps at the access level of subscriber devices. For example, the new Wi-Fi chips of the American company Broadcom, which implement the protocols of the preliminary specification of the IEEE 802.11ac standard, are three times more productive and up to six times more energy efficient than their counterparts for the IEEE 802.11n standard.

According to the forecast of the analytical company In-Stat, by 2015 the volume of production of chips supporting the IEEE 802.11ac standard will exceed 650 million pieces. They will be used in smart TVs, mobile phones, tablet computers, laptops, in the automotive industry, Wi-Fi communication devices. And researchers at the Tokyo Institute of Technology have unveiled a prototype wireless communications system that transmits data at 542 GHz at 3 Gbps. Their plans are to increase the speed up to 100 Gbps

After analyzing the technical, operational and cost characteristics of various equipment, we recommend the EZELINK equipment. The carrier based equipment provides a bandwidth of up to 1 Gbit / s for a distance of up to 4.5 km in the frequency range 71-76 GHz with an output signal of 5-8 dBm (with a 99.99% availability level in the rain zone E). It is possible to adjust the speed of the duplex channels asymmetrically in proportions of 50/50, 75/25 and 90/10%. The experience of using this equipment shows that during heavy showers due to the built-in mechanism of adaptive modulation of transmitted signals, the bandwidth is only slightly reduced without disrupting communication.

1. A number of telecommunications equipment manufacturers, such as Cisco and EZELINK, are already implementing the IEEE 802.11ac standard in their Wi-Fi routers (Linksys EA6500 and EZELINK EZ1900 models), providing gigabit speeds. It is essential that this equipment is backward compatible with IEEE 802.11a / b / g / n devices. Transmitting data at a frequency of 542 GHz with a speed of 3 Gbps. Their plans are to increase the speed up to 100 Gbps

The popularity of smartphones, tablet computers, and mobile subscriber devices is constantly growing. At the same time, the user is completely uninterested in which telecommunication platform and how he receives this or that service. The main thing for him is to have access to any telecommunication services, including telephony, video chat, interactive television, the Internet, at any time and anywhere (at work, on the street or at home). It is also important that smartphones and tablets are increasingly entering the IT infrastructure of many companies. But in order for these devices to become a full-fledged production tool in the enterprise, the issues of their accounting, safety and control-ability must be resolved.

In addition, so that operators and customers can receive the requested service or services, it is necessary to ensure and control the appropriate level of communication services quality - from the management of service level agreements (SLA), conflict management, control of obligations for the lease of channels and services, quality management of Internet services, order management, to customer support and restoration of services.

To solve this problem, a number of leading telecom operators and large organizations are already successfully using the solution from EZELINK (www.ezelink.com) . Its fully virtualized WaaS platform allows you to implement the full range of service and quality management functions.

Today, the problem of building the backbone infrastructure of networks is very urgent, including networks of broadband wireless information transmission. While building and upgrading their high-speed communication networks, without detracting from the advantages of SDH / PDH technology, operators are increasingly paying attention to more flexible, cost-effective and scalable packet communication networks that support higher transfer rates.

A number of well-known telecommunications equipmentmanufacturers are already implementing Carrier Ethernet, for example, the Canadian company BTI Systems and the Israeli company RAD Data Communications. In particular, EZELINK Systems' mobile infrastructure solution is a cost-effective and direct path from 2G cellular infrastructure to 4G networks and beyond. This solution consolidates voice, data and control traffic into a single packet infrastructure, creates a reliable and secure foundation for deploying next-generation broadband networks, supports higher bandwidth, and allows service providers to gradually build highly available, fully packet-based infrastructure. EZELINK supports the necessary security functions, prioritization and protection to carry different types of traffic as well as backhaul traffic from different wireless carriers over the same packet connection. This fully integrated end-to-end solution includes the Transmission and Aggregation Platform as well as EZELINK Service Manager and SLA Portal management solutions.

Another end-to-end solution that supports the Carrier Ethernet standard is offered by EZELINK. It is based on the Ethernet service aggregation platform, interface devices, Carrier Ethernet demarcation devices, and the portal for monitoring Carrier Ethernet service performance.

It is part of the EZELINK Network Management System. It is optimized for the needs of operators in terms of service quality assurance. It provides real-time visibility into the performance of Ethernet services using KPIs (Key Performance Indicators) collected over the network from all devices. Measurements are carried out according to ITU-T Y.1731 recommendation. Frame latency and jitter (forward and backward) are controlled,

New radio electronic devices operating in the E-band (E-Band, 71–76, 81–86 and 92–95 GHz) are also of interest. According to the Decision of the State Committee for Radio Frequencies of July 15, 2010 No. 10-07-04-1, for radio relay systems in this range, no permission is required to use frequency ratings (but registration is carried out in accordance with the established procedure). Such equipment is convenient for quickly connecting business centers, exhibitions, video surveillance systems, switching on corporate clients, base stations, organizing backup channels, crossing rivers, etc. Among the manufacturers producing E-band point-to-point communication equipment are EZELINK Wireless.

To expand the operator's network and connect remote base stations or corporate clients, along with the well-known products of EZELINK, new radio equipment has appeared on the telecommunications market. The line of equipment includes radio bridges, which can operate in the frequency ranges 700-900 MHz, 2.4; 3.3-3.8; 4.9; 5, x and up to 7 GHz. Communication range in one span - up to 130 km, throughput - up to 270 Mbit / s, high immunity to interference. By purchasing the appropriate license, a point-to-point radio link can be converted into a point-to-multipoint radio link. The solution based on radio links is quite budgetary when comparing other equal indicators of equipment from other manufacturers (according to our estimates, up to 40%).

Telecom operators are successfully using Wi-Fi technology as an effective addition to their existing wired network. On the basis of these devices and various additional equipment, it is possible to provide a full range of modern communication services to any organization and population. Wi-Fi technology allows you to handle multiple connections, transfer significant amounts of data. This continues to make it a popular solution for indoor, high-traffic and corporate environments. Due to the high bandwidth of Wi-Fi devices, the era of gigabit speeds will come in the next three to four years.

To build Wi-Fi networks, telecom operators are required to use carrier-grade equipment that provides the necessary parameters for bandwidth, reliability, quality and safety. Obviously, the cost of such projects is significantly higher compared to home segment equipment (SOHO). For example, the regional operator EZELINK Telecom in its solutions uses carrier-grade Wi-Fi equipment.

EZELINK Telecom has deployed more than 12,000 Wi-Fi hotspots across the region connected to multiple WLAN controllers. EZELINK Telecom executives said their products and technology provides reliable communications: " EZELINK is the easiest to manage and deploy.
