  • Patent number: 8175550
    Abstract: Elimination of intermodulation interference in a wireless communication system by removing a portion of the spectrum of transmitted signals. According to a received indication of an occurrence of intermodulation interference experienced by a narrowband receiver, mappings are performed between the predetermined narrowband channel frequency on which the narrowband receiver operates and the occupied channel frequencies of at least one broadband transmit signal. Narrowband candidate frequency ranges that linearly combine into frequencies that overlap the predetermined narrowband channel frequency are determined based on the mappings. The narrowband candidate frequency ranges that potentially contribute to the intermodulation interference are then selectively filtered by at least one notch filter until the intermodulation interference is substantially eliminated.

  • Patent number: 7480486
    Abstract: A wireless repeater and method for managing air interface communications is provided. A repeater may include a donor antenna, a coverage antenna, a mobile station modem, a processor, and data storage. The donor antenna will receive a plurality of air interface beams on the forward link from a radio access network. The coverage antenna will pass each forward link beam received to a mobile station being served by the repeater. Further, the donor antenna will pass each forward link air interface beam to the MSM, where the MSM will apply a rake receiver to identify a signal characteristic of the forward link of each beam received, and the processor will record in the data storage the signal characteristic corresponding to each beam. Given this data, the repeater will select an air interface beam with the most preferable signal characteristic, and will keep only this beam active for reverse link communications.

  • Patent number: 7437159
    Abstract: An apparatus and method for overcoming pilot pollution in a wireless communications network. The apparatus boosts a preferred pilot signal within a geographical area that is suffering from pilot pollution. The boosted pilot signal is stronger than the pollution in this area, and causes mobile stations to lock onto the boosted pilot signal rather than the pollution. A directional receiving antenna on the apparatus receives the preferred pilot signal from a selected base station. After amplifying the preferred pilot signal, the apparatus transmits the boosted pilot signal from an antenna within the geographical area. In this manner, mobile stations lock communicate with the selected base station when within the geographical area rather than the base station responsible for the pilot pollution. This may result in fewer dropped calls from the network and fewer inappropriate hand-offs.

  • Patent number: 7277735
    Abstract: A method and system for simultaneous ringing in a wireless communication system. Upon receipt of a request to connect a call to a given wireless communication device (WCD), a switch or other entity will determine that the given WCD subscribes to a simultaneous ringing service and will identify one or more other WCDs to simultaneously ring. The switch or other entity will then determine which of those one or more WCDs, if any, are currently operating in the same wireless coverage area as the given WCD and will then simultaneously ring the given WCD and each of the other WCDs, if any, that is determined to be operating in the same wireless coverage area.

  • Patent number: 7035587
    Abstract: A wireless signal repeater that cuts off output transmission when the repeater is receiving less than a threshold level of input signal strength (e.g., too low or nonexistent). When operated in the reverse link of a cellular wireless system, the repeater advantageously reduces transmission of noise toward a cellular base station when the repeater is receiving no (or insufficient) signal from the a mobile station. Similarly, when operated in the forward link direction of a cellular wireless system, the repeater advantageously reduces transmission of noise toward a mobile station when the repeater is receiving no (or insufficient) signal from a base station.

  • Patent number: 6959196
    Abstract: A method and system for reporting outside temperature. A temperature source continually provides a measure of outside temperature to a base station in a wireless communications system. The base station responsively inserts an indication of outside temperature into control channel messages and broadcasts the control channel messages for receipt by mobile stations being served by the base station. A mobile station receives the control channel messages, extracts the temperature indication from the messages, and continually displays an indication of outside temperature for viewing by a user. Conveniently, the temperature source can be a simple temperature gauge mounted to a base station tower or other entity in or near the cell site being served by the base station, so that mobile stations in the cell site can be made to display the local temperature.
