This course introduces the principles of cellular communications systems. Second-generation (2G) digital, mobile cellular, and personal communications systems (PCS) concepts are discussed, including the cellular concept, frequency reuse, propagation, multiple access, power control, handoff, and traffic engineering. Limitations of 2G cellular systems are described, and improvements proposed by 2.5G and 3G cellular standards to support high-rate data services are presented. Emphasis is placed on layer 2 and above, such as retransmission protocols, medium access control, call processing, interworking, radio resource management (e.g., frequency, time, and power), QoS provisioning, scheduling, and mobility management (e.g., mobile IP). The Wireless Local Area Networking IEEE 802.11 WLAN, the Wireless Metropolitan Area Networking IEEE 802.16 (Fixed and Mobile) WiMAX, and Wireless Personal Area Networking IEEE 802.15 Bluetooth are discussed for their roles in 3G. The Media Independent Handover standard IEEE 802.21 (e.g., integrating WLAN and 3G cellular networks to provide session/service continuity) is also introduced. Cellular standards are examined, including US 2G code-division multiple access (CDMA) IS-95A, 2.5G IS-95B, 3G cdma2000 1x, and 1x-EVDO. Other standards discussed include European 2G time-division multiple access (TDMA) Global System for Mobile communication (GSM), 2.5G General Packet Radio Service (GPRS), 2.5G Enhanced Data Rates for GSM Evolution (EDGE), 3G wideband-CDMA (W-CDMA), and 4G Long Term Evolution (LTE).
