Abstract
A dynamic, efficient, and full-duplex wireless local network is presented. The local central station equipment is implemented by implementing a Frequency Division Multiple Access (FDMA) technique on local inbound data and a Time Division Multiple Access (TDMA) technique on at least local outbound data. Conversely, each subscriber unit implements the TDMA technique on local outbound data and the FDMA technique on local inbound data. In so doing, wireless two-way communications can be established between the central station, subscriber units, and remote stations wherein the allocated carrier frequency band is fully utilized and the outbound data bandwidth can be dynamically adjusted to accommodate the bandwidth requirements of different communication applications.
