• Sommario/riassunto: Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form ofwire) carry the signal over part or all of the communication path and the network is the totality of switches, transmission links and terminals used for the generation, handling and receiving of telecoms traffic.Wireless networks are rapidly evolving, and are playing an increasing role in the lives of people throughout the world and ever-larger numbers of people are relying on the technology directly or indirectly.The area of wireless communications is an extremely ric
