A wireless network is a special case of a computer network where computers and digital devices are interconnected using radio signals rather than physical wires.
The term “wireless network” is often used to refer specifically to connections made using the Wi-Fi wireless radio protocol.
Wireless networking is a method by which homes, telecommunications networks and business installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Admin telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure.
