Wireless Access and Transport Technologies


This course addresses radio resource allocation, sharing, control and management for wireless and cellular networks. It basically addresses PHY and MAC layers. The first and major emphasis is on radio access network architectures, procedures and methods. We will address resource sharing and radio resource allocation, control and management for TDMA, CDMA and OFDMA systems.

The course addresses Uplink and downlink interference management, scheduling issues and capacity evaluation for the air interface or the radio access network. Physical to logical channel mapping for GSM and UMTS networks are also described along with the RAN architecture and the associated procedures and protocols. QoS management and service classes will be presented and debated.

The course also addresses transport technologies. The use of dedicated lines, ATM and IP and therefore the evolution from circuit to packet switched technologies are discussed and analysed. The impact of current choices on QoS and mobility management as well as the trends and evolutions toward beyond 3G networks will be discussed.
