High speed Asynchronous Transfer Mode (ATM)wireless networks are assuming a growing interest inthe personal communication area [1–6]. This paperdescribes the design of a wireless ATM system, whichis being implemented in the ’’MEDIAN‘‘ project belongingto the European Community (EC) Advance CommunicationsTechnologies and Services (ACTS) programme.The Medium Access Control (MAC) aims at providinga simple and efficient transport for ATM cells from aBase Station (BS), interfaced with the ATM BroadbandIntegrated Service Digital Network (B-ISDN), to ATMPortable Stations (PSs) and vice versa. A TimeDivision Duplex (TDD) scheme is adopted in whichuplink and downlink frame durations can be variedframe-by-frame, in order to fit the presentuplink/downlink traffic mix. Moreover, in the uplink,a contention-free based technique is considered inwhich the slots are assigned to the calls depending onthe present load of the PS uplink buffers.The proposed interworking with the ATM network isbased on the concept of intercepting the ATMSignalling and Management Cells at the BS, in order todeduce from the ATM Q.2931 messages informationrelevant to the registration, the call set-up and theMAC procedures.
