Netwoeks Global System for Mobile communications or Grouped Specials Mobile communications, initiated by the European Commission, is the second-generation mobile cellular system aimed at developing a Europe-wide digital cellular system.
The main objective of GSM is to remove any incompatibility among the systems by allowing the roaming phenomenon for any cell phone. It also supports speech transmissions between MSs, emergency calls, and digital data transmissions.
Every time the MS has to communicate with a BS, it must correctly identify itself. A MS does this by storing the phone number or the number used to contact the MSpersonal identification number for the station, authentication parameters, and so on in the SIM card.
A wireless bridge is a wirleess component used to connect two or more network segments LANs or parts of a LAN which are physically and logically by protocol separated. Netwlrks wireless local area network WLAN links devices via a wireless distribution method typically spread-spectrum or OFDM radioand usually provides a connection through an access point to the wider internet.

The aim of IEEE The major protocols include IEEE A MANET mobile ad hoc networks consists of a number of mobile devices that come together to form a network as needed, without any support from any existing Internet infrastructure or any other kind of fixed stations.
MANET can be defined as an autonomous system of nodes or MSs also serving as routers connected by wireless links, the union of which forms a communication network modeled in the form of an arbitrary communication graph.
