1. What is the maximum range of Wi-Fi operation?
The most remote connection that could be established between two devices operating under the 802.11
standard is 382 km. This record was set by Ermanno Pietrosemoli. To do this, he needed to finish the Intel
serial equipment a little and set up 2 directional antennas on each other so that they fell into the line of
sight. Ermanno managed to squeeze out 3 Mbit/s, and he spent only $ 60 on equipment.

2. Wi-Fi has been around for a long time!
Back in 1991, At&t company launched the first devices for wireless data transmission at 2.4GHz radio
frequency. Then this standard was called WaveLAN. It could provide data transmission at speeds from 1
to 2 megabits per second.
In 1997, the world saw the first 802.11 specifications. It was essentially the same WaveLAN from At&t.
And the following specification has already received the proud name of WI-FI — 802.11b. This standard
allowed data to be transmitted already at a speed of up to 11 megabits per second.

3. Wi-Fi can transmit information faster than over
wires
Now the fastest standard is considered to be 802.11ac, it is capable of transmitting information at a
speed of 1.3 GB/s, which is faster than gigabit fiber-optic Internet. And they are also currently developing
a new standard that will be able to deliver a speed of 7 GB/s.
