Wireless networking (also known as “WiFi”) is the use of radio waves and/or microwaves to maintain communication channels between computers or other network devices. In short, wireless is a radio signal between a transmitter and a receiver access point.
While conventional networking ('wired networking') makes use of copper or fibre optic cabling between network devices, wireless networking instead relies on radio signals to connect network devices such as laptops, smart phones and tablets. Wireless allows users to be mobile, by providing network access from areas which are not usually wired, such as green spaces and other outdoor areas.
Wireless networks are affected by environmental conditions such as physical obstructions, weather conditions, and other radio equipment which can cause interference and reduce signal strength and range.
