There are several frequency bands within the radio spectrum that are used for the Wi-Fi and within these there are many channels that have been designated with numbers so they can be identified.Īlthough many Wi-Fi channels and Wi-Fi bands are normally selected automatically by home Wi-FI routers, for larger wireless LANs and systems it is often necessary to plan the frequencies used. It is used as the main wireless communications bearer in wireless LANs as well as for small home WLANs as well.

Wi-Fi IEEE 802.11 is used by very many devices from smartphones to laptops and tablets to remote sensors, actuators televisions and many more.
