Abstract
A radio base station in a Fixed Wireless Access System broadcasts downlink data packets, each packet being transmitted on a single logical channel. A plurality of network subscribers in a sector may be members of a user group, each user group configured to receive and transmit packets transferred on a specific single logical channel only. Packets include a destination address which specifies a member of the user group. The packets include a token which specifies which user group member may transmit uplink data to the base station on the next frame. Logical channels are yielded for use by circuit switched traffic when required.
