Fundamental of wireless network

Learn the answer by reading our in-depth guide to wireless technologies.

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.

Some of these terms may be familiar to you: radio and television broadcasting, radar communication, cellular communication, global position systems (GPS), WiFi, Bluetooth and radio frequency identification are all examples of “wireless”, with wildly different uses in some cases.
