Course Details

GSM and GPRS remain the foundation technologies for many mobile networks worldwide, offering voice and data services through globally standardized network infrastructures. This course explores the network architecture for both circuit and packet switched services, detailing the air interface and the initial procedures required for network access. Network usage is also explained, showing how calls, texts and data sessions are established and maintained as the subscriber moves around the network.
