Abstract

Apparatus, and an associated method, for providing WLAN (wireless local area network) service through a fixed wireless access communication system. WLAN transceivers are fixed in position at subscriber stations of the fixed wireless access communication system. Each WLAN transceiver defines a coverage area. Through appropriate positioning of the WLAN transceivers at the subscriber stations, overlapping coverage areas are formable and between which handovers of communications with a mobile station are effectuated when a mobile station travels out of one coverage area and into another coverage area.

Claims

1-24. -24. (canceled)

25. For use in a wireless access network comprising a plurality of base stations capable of bidirectional time division duplex (TDD) communication with wireless access devices disposed at a plurality of subscriber premises, a TDD frame transmission synchronization apparatus comprising:

a frame allocation controller capable of receiving from a first radio frequency (RF) modem shelf associated with a first base station access requests generated by a first group of wireless access devices communicating with said first base station and determining from traffic requirements associated with said access requests a time duration of one of the longest downlink portion of TDD frames used by a first one of a plurality of RF modems in said RF modem shelf to communicate with a first wireless access device, wherein said frame allocation controller further determines a frame allocation of the downlink portion and the uplink portion of TDD frames used by said plurality of RF modems to communicate with said first group of wireless access devices.

26. For use in a wireless access network comprising a plurality of base stations, each of said plurality of base stations capable of bidirectional time division duplex (TDD) communication with wireless access devices disposed at a plurality of subscriber premises in an associated cell site of said wireless access network, a method of transmitting a beam, the method comprising:

transmitting directed scanning beam signals in a sector of a cell site associated with a first base station of the wireless access network, wherein said transmit path circuitry transmits at a start of a TDD frame a broadcast beam signal comprising a start of frame field and subsequently transmits downlink data traffic in a downlink portion of said TDD frame to at least one of said wireless access devices using at least one directed scanning beam signal.
