Mobile Communications Network Technology

Principles of data communications

• Providing error free transmission (automatic repeat/request and cyclic redundancy checking)
• Circuit and packet switched networks (PSTN, ISDN, ATM)
• Voice/video transmission (sampling, coding, packetization)
• Radio system transmissions (CDMA, FDMA, TDM)

2nd generation mobile networks (GSM/CDMA)

• GSM air interface (frequency and time division multiplexing)
• GSM cellular architecture (BSC, MSC, HLR, VLR)
• Call initiation and mobility management procedures

General Packet Radio Service (GPRS)

• GPRS bandwidth usage
• GPRS architecture (SGSN, GGSN, packet switch domain)
• GPRS air interface (coding options and security)

3rd generation mobile networks

• 3rd generation evolution (from 2G core to R5 all IP network)
• UMTS service capabilities (WCDMA, over-the-air channel structure)
• Call initiation and mobility management procedures
