Abstract: A method and apparatus for assigning location estimates from a first transceiver of a plurality of wireless transceivers to a second transceiver is disclosed. The present invention makes use of a low power short-range auxiliary communication link incorporated within networked devices to interact with nearby devices for obtaining location estimates of the current location of a device. Confidence levels are then assigned to the information obtained from the interactions with the nearby devices, and a determination of whether to update the location estimate is made.

Abstract: In a model of a wireless communication system service area (160), a set of characteristics associated with the reception of a model signal (210) are calculated (308), preferably using ray-tracing techniques, wherein the model signal (172) is transmitted from a selected location (162) to a receiver location (166). Next, a set of characteristics that describe a received signal at a receiver location in the wireless communication system service area are measured (316), wherein the receiver location corresponds to the receiver location in the model (160). Thereafter, a relationship between the calculated set of characteristics and the measured set of characteristics is determined (318), and the location of the subscriber unit that transmitted the received signal is estimated (320) in response to the relationship between the calculated set o f characteristics and the measured set of characteristics.

Abstract: A peer device (132) is arranged and programmed for maintaining a virtual queue for an event, and a personal presence identifier (122) is carried by a user and coupled to the peer device by a short-range two-way wireless link. The peer device and the personal presence identifier are arranged and programmed to establish (58) a two-way personal area network with one another when the personal presence identifier is within wireless transmission range of the peer device. The personal presence identifier and the peer device are also arranged and programmed to exchange (82) needs specifications and capability specifications with one another after establishing the two-way personal area network.

Abstract: A method and apparatus for determining the location of a communication unit in a CDMA system includes in a first embodiment, sending a location request via a spread spectrum signal to the subscriber (140), and receiving in return a subscriber signal including a response message showing a receive time of a particular symbol of the base's spreading sequence and a transmit time of a particular symbol of the subscriber's spreading sequence. The base (130), along with other receiving base(s) (140), also receives a predetermined symbol of the subscriber spreading sequence, and each determines a respective receive time of the predetermined symbol. The received information is then processed, along with known base location and delay information, to determine the subscriber location. If insufficient number of bases are capable of communicating with the subscriber, for example due to high loading/interference, auxiliary bases (121) are also provided for receiving from or transmitting to the subscriber.

Abstract: A method for determining a subscriber unit location in a communication system is provided. The method includes the steps of receiving a signal from the subscriber unit at a first base station, determining a first receive time of the signal based on a sequence of spreading symbols at the first base station, determining a first angle of arrival of the signal at the first base station, and determining the location of the subscriber unit from the first receive time, the first angle of arrival, and further predetermined information about the first base station. The signal is formed via modulation by the sequence of spreading symbols.
