One step in the evolution of the real-time GSM services is the Enhanced Circuit Switched Data (ECSD) which is being developed in ETSI as GSM Phase 2+ work item (EDGE Phase 1) parallel to Enhanced General Packet Radio Service (EGPRS). ECSD radio interface deploys 8-PSK modulation in addition to GMSK and thus enables higher data throughput per time slot. This paper gives an overview of the ECSD concept and examples of applications that it supports. The focus is in the link level and the radio network level performance of different ECSD data rates in various test environments. It is shown that by utilising the proper link adaptation mechanism, even demanding transparent high data rate services, like video, can be supported with a good coverage.

Abstract| W e investigate the feasibility o f transmitting MPEG-2 AAC Advanced Audio Coder music over packetswitched bearers of an Enhanced General Packet Radio Services cellular network. Streaming data applications like AAC music di er from conversational voice in that they permit a larger transmission delay and delay jitter than the former. In addition, AAC m usic can tolerate a higher frame error rate than voice by using error concealment techniques at the receiver. This creates the opportunity t o transmit AAC m usic over data-optimized, high-throughput and nominally high-error rate, wireless networks, by using appropriate performance enhancing techniques. In particular, we i n vestigate the performance with the following techniques: i Link-layer retransmissions; ii Dynamic packet assignment; and iii Packet interleaving or shu ing. We nd that all the above techniques are desirable in order to simulateneously achieve a high spectral e ciency and the required quality. While this paper is focused on one application, the conclusions and insights are applicable to most streaming audio and video applications.
