|20090285134||Wireless access system using multiple modulation formats in TDD frames and method of operation - There is disclosed a radio frequency (RF) modem shelf for use in a fixed 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. The radio frequency (RF) modem shelf comprises: a) a first RF modem for communicating with a plurality of the wireless access devices using TDD frames, each TDD frame having an uplink for receiving data and a downlink for transmitting data; and b) a modulation controller associated with the RF modem shelf for determining an optimum modulation configuration for each of the plurality of wireless access devices communicating with the first RF modem. The modulation controller causes the first RF modem to transmit downlink data to a first wireless access device in a first data, block having a first optimum modulation configuration and to transmit downlink data to a second wireless access device in a second data block having a different second optimum modulation configuration.||11-19-2009|
|20090111457||Wireless communication system and device for coupling a base station and mobile stations - A wireless communication system is provided that includes a wireless communication device in wireless communication with a base station and mobile stations. The wireless communication device includes first and second transceivers coupled to each other. The first transceiver is coupled to an antenna and is operable to communicate with the base station, which is also in wireless communication with other wireless communication devices. The second transceiver is coupled to another antenna and is in wireless communication with the plurality of mobile stations. The first transceiver receives a first signal from the base station intended for a one of the mobile stations, and in response the second transceiver transmits the first signal to the mobile station. The second transceiver receives a second signal from the mobile station intended for the base station, and in response the first transceiver transmits the second signal to the base station.||04-30-2009|
|20080268835||Wireless communication system and device for coupling a base station and mobile stations - A wireless communication system comprising first and second transceivers. The first transceiver communicate with a base station, wherein the base station communicates with the first transceiver and a plurality of other wireless communication devices according to a wide area wireless communication protocol. The second transceiver is coupled to the first transceiver and communicates with a first mobile station, wherein the second transceiver communicates with the first mobile station according to a local area wireless communication protocol. The first transceiver receives from the base station a first downlink signal intended for the first mobile station and transmits the first downlink signal to the second transceiver. The second transceiver re-transmits the first downlink signal to the first mobile station as a second downlink signal according to the local area wireless communication protocol.||10-30-2008|
|20080261588||TDD FDD communication interface - TDD access equipment modified by introducing a frequency change at the normal TDD guard point, with respective downlink or uplink periods for individual subscriber stations offset to form overlapping frames. Cyclo-stationary processing, block equalization, and burst timing coordination allow the boundary between downlink and uplink portions of both frames to be set dynamically, improving spectral efficiency. Fast frequency switching within an allotted physical slot enables synchronization of time-sharing the dedicated frequencies to be maintained among subscriber stations. Duplex spacing between downlink and uplink frequencies for individual subscriber stations, combined with in-depth filtering of received signals, prevents spurious out-of-band transmission signal strength from reaching an interference level.||10-23-2008|
|20080259868||Wireless communication system and associated method for routing messages to wireless networks - A wireless communication system is provided that includes a base station and a routing map. The base station is in wireless communication with a plurality of wireless networks. The routing map stores information relating to a location of a mobile station in wireless communication with a first wireless network. The base station receives a signal for the mobile station and transmits the signal to only the first wireless network, according to information retrieved from the routing map related to the location of the mobile station. The wireless network may be a wireless local area network. A handover of the mobile station from the first wireless network to a second wireless network may be made based upon a measured signal characteristic between the mobile station and the first and second wireless networks.||10-23-2008|
|20080259826||System for coordination of communication within and between cells in a wireless access system and method of operation - 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.||10-23-2008|
|20080254801||Method and apparatus for establishing a priority call in a fixed wireless access communication system - A wireless communication system has a plurality of subscriber stations linked by radio with a network infrastructure coupled to a correspondent node. A call is originated at a subscriber station apparatus. The apparatus includes a call establishment message generator coupled to receive an origination indication of the call. The call establishment message generator generates a call establishment message to initiate call set-up procedures that precurse a request to establish the call between the subscriber station and the correspondent node. The apparatus also includes a response detector coupled to receive an indication of a network-infrastructure generated response to the call establishment message. The response detector detects whether the response to the call establishment message indicates that communication resources are available to establish the call. The apparatus further includes a call set-up emulator coupled to the response detector. The call set-up emulator emulates normal call set-up operations at the subscriber station at least for a period responsive to detection by the response detector of unavailability of the communication resources to establish the priority call.||10-16-2008|
