June 20 - International Wi-Fi Day

But how much do we know about Wi-Fi?

🌏Wi-Fi in its modern form was invented in Australia.

Modern Wi-Fi operates in two frequencies.

The problem is that in addition to routers and gadgets, most of our home electrical equipment works in the same range.

A microwave oven, a radio nanny, a TV, other electrical appliances, including other routers – all of them produce certain radiation that can interfere with the good operation of the Internet.

But there are also advantages of Wi-Fi
▪ Mobile devices connect to the home Internet, which was not possible with the old wired system.
▫️ You can watch movies online and talk via Skype in the hall, kitchen, utility room and even on the roof — anywhere in the coverage area.
▫ the Internet is available simultaneously to all households. No one bothers each other.
