Basic Concepts of Wireless Network

A wireless network is the computer network that uses wireless data connections for connecting 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. Wireless 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. In this paper we study different types of wireless networking systems and their topologies used.
