It can carry a maximum of three non-overlapping channels. Often referred to as the 2.4 GHz band, this spectrum is the most widely used of the bands available for Wi-Fi. The main bands used for carrying Wi-Fi are those in the table below: Whilst the ISM bands are available globally, there are some differences and restrictions that can occur in some countries. The ISM bands are not only used by Wi-Fi, but everything from microwave ovens to many other forms of wireless connectivity and many industrial, scientific and medical uses. This gives access to everyone to use them freely. These bands have been internationally agreed and unlike most other bands, they can be used without the need for a transmitting licence. Wi-Fi is aimed at use within unlicensed spectrum - the ISM or Industrial, Scientific and Medical bands. By using some simple settings in the Wi-Fi router and wireless extenders, it is possible to make improvements to the Wi-Fi installation network speed. Using many Wi-Fi access points around a large building or area, frequency planning is essential so that the best performance can be obtained from the wireless LAN.Įven for home systems where Wi-Fi extenders and Wi-Fi repeaters are used, it is helpful to understand which frequencies are available and how these can be best used. 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.
