wireless, MAC, WATM and QoS.


A proposal of a medium access scheme with distinction of service classes for Wireless ATM is presented in this paper. The proposed protocol uses an efficient scheme of reservation for uplink channels and it allows facility to satisfy the QoS of each service class. The structures of uplink and downlink frames are explained in details. The delay analyses for the contention channel (uplink) and for data transmission channels (uplink and downlink) are carried out. The results show the number of average terminals in backlog can be kept very low in the contention channel and the cell delay at terminals or at base station for each of service class can be controlled to satisfy easily the QoS.
