The fastest average wifi speed is in South Korea. The shape of wifi waves is spherical or ellipsoidal.
Wifi works on radio waves. The wifi works mostly on two frequencies, 2.4 GHz and 5 GHz.
The largest free wifi zone is 20 Km, and it is located in Patna, Bihar.
The latest version of wifi is wifi 6 or 802.11ax.
The invention of Wifi is done by an accident.
The Wifi alliance owns the Wifi logo. The headquarter of Wifi Alliance in Austin, Texas, USA.
