Quality of Service Management for Wireless ATM

ATM operates on reliable wire-line backbones providing high-quality transport services in terms of delay, data corruption and data loss. When moving to the mobile radio channel, specific actions are undertaken to cope with a much tougher communication environment where noise, interference, and terminal mobility drastically cut down the network reliability and performance. This paper identifies alternative ways to improve the performance of Wireless ATM links. Forward error control schemes are analysed. In particular, Block coded and convolutional coded cells are simulated and evaluated throughout the frequency bands and data rates recommended for the WATM channel mode. Finally, some consideration of code selection will be discussed
