Mobile and wireless technologies have evolved beyond recognition when the first radio signal was transmitted by pioneers in the late nineteenth century. Since then Radio waves have been used as basis of telephony, audio & video broadcast and in radar system. Thus it is utmost vital to provide a safe and secure channel to user for communication. Topic covered under this paper will cover brief of cellular network, their architecture, security issue and mechanism to depict it through Wireless Application Protocol (WAP) & new 3G cellular network architecture. Accordingly, through this paper they survey issues and dilemma in enhancing the survivability of mobile wireless network through designing of end to end communication in different environments where path from source to destination is not available at any given instant of time.
