Wireless network
Computer network not fully connected by cables / From Wikipedia, the free encyclopedia
A wireless network is a computer network that uses wireless data connections between network nodes.[1] Wireless networking allows homes, telecommunications networks and business installations to avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.[2] 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.[3]
For radio broadcast affiliations and two-way radio systems, see radio network.
