GPRS is a packet-switching data network that is overlaid on the existing cellular voice network, using the same radio frequencies and cellular towers. When combined with the existing Global System for Mobile communication (GSM), GPRS offers a complete voice and data solution with significant advantages over other solutions. Intel views GPRS as an important step in the evolution of wireless communications, and is helping to advance this technology. Organizations that rely heavily on wireless Wide Area Networking should consider implementing a GPRS solution. This paper is intended to provide a detailed introduction to GPRS technology. Sources for further information are provided at the end of the paper.
