Wifi in electronics

Wi-Fi is a wireless technology used to connect computers, tablets, smartphones and other devices to the internet. Wi-Fi is the radio signal sent from a wireless router to a nearby device, which translates the signal into data you can see and use.

What is Wi-Fi and its types?

The five Wi-Fi technologies are A, B, G, N and AC. B and G use the 2.4 GHz frequency; A and AC use the 5 GHz frequency; and N uses both 2.4 and 5 GHz frequencies. Your choice for your home or business will come down to three: Wireless G, N or AC. Routers that only support Wireless B are no longer manufactured.
