Wireless ATM (W-ATM) networks have been studied extensively in recent years. Extension of ATM network services to the wireless environment Faces many interesting problems. The original ATM network was designed for high-speed, noiseless, reliable channels. None of these characteristics are applicable to the wireless channel. One of the most critical aspects of a W-ATM network is the medium access control (MAC) protocol used by mobile terminals (MTs) to request service from the base station (BS), which has to consider the quality of service (QoS) of the specific application. In this article the authors analyze some recently proposed MAC protocols, particularly those for TDMA systems, and discuss their advantages and disadvantages.
