Comprehensive Study of Mobile Networks

:In telecommunication a Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor .Wireless operations permit services, such as long-range communications, that are impossible or impractical to implement with the use of wires. The term is commonly used in the telecommunications industry to refer to telecommunications systems which use some form of energy to transfer information without the use of wires. Information is transferred in this manner over both short and long distances. In this paper we are reviewing different wireless technologies and discussing about the future of wireless technologies used for cellular or mobile networks.
