Abstract
High-speed asynchronous transfer mode (ATM)wireless networks are assuming a growing interest in thepersonal communication area. This paper proposes anaccess technique for such networks, which is being implemented in the MEDIAN project belonging tothe European Community (EC) Advanced CommunicationsTechnologies and Services (ACTS) program. The proposedaccess technique aims at providing a simple, efficient, and transparent transport for ATM cells from abase station (BS) interfaced with the ATM network, toATM portable stations (PSs) and vice versa. Atime-division 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. In the uplink, anappropriate packet reservation multiple access(PRMA)-based technique is considered.
