Abstract
A wireless communications system includes a base station and a plurality of terminal units which can be mobile. The base station establishes connections among sets of two or more of the mobile units so as to permit private, full-duplex conversations to take place within each set of terminal units. A number of such conversations can take place concurrently. The base station allocates packet time slots for each active terminal unit to transmit, and dynamically reduces the allocation per terminal unit only as the number of active terminal units increases. The terminal units are able to transmit the same isochronous information (such as voice) regardless of the number of packet time slots allocated to the terminal unit, by compressing the data by a greater amount when fewer packet slots are allocated, and by a lesser amount when a greater number of packet slots are allocated per unit of time. The system is able to support a range of numbers of concurrent conversations, while dynamically maximizing the quality of such communications at different times.
