An ATM-based wireless network capable of supporting integrated voice, video and data services with Quality-of-Service (QoS) control is proposed as a key element of the future distributed multimedia computing scenario. A specific architecture for "wireless ATM" is described, and design issues are briefly discussed for each major functional layer of the network. The system approach is based on the incorporation of wireless channel specific medium access, data link and wireless control layers into a mobility-enhanced ATM protocol stack. Selected software emulation results are given for applicable Medium access Control (MAC) and Data Link Control (DLC) protocols. The paper concludes with a brief view of related ongoing prototyping activities aimed at demonstrating a seamless wired plus wireless multimedia networking environment.
