  • Patent number: 7945263
    Abstract: Method for transferring service for a mobile station call signal from a first base transceiver station to a second base transceiver station in a wireless mobile telecommunication system, while a call is in progress. The method can include receiving at a base transceiver station an access burst from a mobile station with a call already in progress and requiring service from the base transceiver station. Based on the received access burst, the base transceiver station can electronically steer a beam of an adaptive antenna array of the base transceiver station toward a location of the mobile station.

  • Patent number: 6952408
    Abstract: A method of frequency hopping is supported by a basestation having a broadband transceiver. The method permits changing physical channels upon which mobile subscribers communicate with the basestation, wherein the broadband transceiver is operated using static transceiver frequencies, the method exclusive of switching communication signals between transceivers. In one embodiment, the method maps baseband output signals from a digital channelizer which represent physical channels to ones of digital signal processors representing logical channels and baseband input signals of a digital combiner to ones of logical outputs of digital signal processors according to a mapping signal.

  • Patent number: 6230026
    Abstract: A wireless telephone architecture employs a broadband transceiver that is coupled to a digital channelizer and digital combiner, such as may employ a real-time Fast Fourier Transform, to extract or combine a set of simultaneous baseband signals. The baseband signals which represent physical channels are mapped to a bank of digital signal processors representing logical channels according to a mapping instituted at the initialization of the call. The mapping is changed on a periodic basis to follow a predetermined frequency hopping schedule. Frequency hopping is thus enabled in a statically tuned broadband transceiver.
