2G Cellular Series

Series Highlights

Second Generation (2G) cellular services were the first digital cell services and were quickly followed by 2.5G services, that is, GPRS to facilitate the first cellular text-based web services and GPRS remains the basis for many Machine to Machine (M2M) telemetry today. The Ossidian 2G Cellular Series comprises six fundamentals and advanced modules addressing 2G and 2.5G core network architecture and radio frequency standards.
