Part A

125 marks
a

Compare and contrast the system architectures of GSM and GPRS.

2 marks

Answer

GSM is a circuit-switched architecture designed primarily for voice communication using dedicated channels. In contrast, GPRS is a packet-switched overlay on the GSM network that introduces the SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node) to handle data packets, enabling always-on connectivity and efficient resource utilization for data services.

b

Demonstrate the process of handover in mobile communications.

3 marks

Answer

Handover is the process of transferring an ongoing call or data session from one base station to another as a mobile station moves. It involves: 1) Initiation, where the mobile or network detects signal degradation; 2) Resource reservation at the target base station; 3) Execution, where the connection is switched; and 4) Completion, where the old connection is released.

c

List the types of Medium Access Control (MAC) techniques used in wireless networks.
