Hybridization of advance technologies in the field of WLAN

Wireless communication is the transfer of information over a distance without the use of enhanced electrical conductors or "wires”. The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications). Wireless wide area cellular network solutions have been around for many years. Widespread adoption has been slow due to issues with coverage, cost, performance, and secure remote access to business networks. The deployment of the Global System for Mobile Communications (GSM)-based General Packet Radio Service (GPRS) has the potential to change this situation and to provide connectivity “anytime and anywhere.” This paper reviews the underlying GSM circuit switched technology and the packet-data capabilities added by GPRS. Here we give the brief description of GPRS technologies and its comparision with GSM technology.
