 Wireless network A wireless network is a computer network that uses wireless data connections between network notes. 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. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level layer of the OSIO model network structure. Examples of wireless networks include cell phone networks, wireless local area networks, WLANs wireless sensor networks, satellite communications networks, and terrestrial microwave networks.
