A wireless network is a computer network that uses wireless data connections between network nodes. 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. This implementation takes place at the physical level layer of the OSI model network structure. Examples of wireless networks include cell phone networks , wireless local area networks WLANs , wireless sensor networks, satellite communication networks, and terrestrial microwave networks. The first professional wireless network was developed under the brand ALOHAnet in at the University of Hawaii and became operational in June Wireless personal area networks WPANs connect devices within a relatively small area, that is generally within a person's reach. A wireless local area network WLAN links two or more devices over a short distance using a wireless distribution method, usually providing a connection through an access point for internet access.
