  • Publication number: 20110201357
    Abstract: A mobile device receives data transmissions, via a coupled receiver antenna array, from a transmitter antenna array of a serving base station. The mobile device determines relative distances, with respect to the serving base station, associated with signal strength measurements on the received data transmissions. The signal strength measurements are compensated, at the mobile device and/or a remote location server, in three-dimensional space based on corresponding transmitter and/or receiver antenna pattern, and/or mobile orientation information for estimating the relative distances. The estimated relative distances are refined by fitting a function of the azimuth and elevation angles. A location for the serving base station and/or the mobile device is determined or refined based on the refined relative distances to be shared among a plurality of users of the remote location server. Fixed or adaptive antenna patterns are supported at the serving base station and/or the mobile device.

  • Publication number: 20110199185
    Abstract: A RFID reader of a RFID enabled mobile device receives RFID information from a RFID tag attached to an object. In instances where the RFID enabled mobile device is GNSS enabled, a GNSS position of the RFID enabled mobile device is determined to associate, for example, by location stamping, with the received RFID information. The location-stamped RFID information is communicated to a remote location server, where location-based RFID information is received from a plurality of users. The RFID enabled mobile device may communicate at least a portion of the received RFID information to the remote location server. When GNSS is not enabled, the RFID enabled mobile device estimates its own location utilizing location information, if available, for the object in the received RFID information. Otherwise, the RFID enabled mobile device acquires location-based RFID information from the remote location server so as to determine its own location.

  • Publication number: 20110201336
    Abstract: A multi-radio mobile device receives data transmission of a session from a serving access network in a heterogeneous network system comprising difference access networks. A handoff is performed based on the received data transmissions. User-level QoS for the wireless communication session is adjusted during the handoff based on connection QoS information in the current location of the multi-radio mobile device and/or a velocity of the multi-radio mobile device. Location-based network connection information, comprising call drop information and the connection QoS information, in the current location of the multi-radio mobile device is acquired from a location server. A target access network or a different base station in the serving access network associated with the highest connection QoS is selected. The user-level QoS is adjusted during the handoff for receiving the wireless communication session from the selected target access network or the different base station in the serving access network.

  • Publication number: 20110199262
    Abstract: A GNSS enabled device that is communicatively coupled to a network, receives time stamps via the network. The time stamps are generated based on reference clock signals within the network. GNSS receiver clock signal frequency may be adjusted based on the time stamps. When GNSS satellite signals and/or SRN signals are not available, the time stamps enable synchronization with GNSS satellites. Network clock signals and/or time stamps may be generated by an access point, a DSL modem, a cable modem and/or a primary reference clock within the network. A series of time stamps may be utilized for adjusting frequencies. Clock signals may be generated for adjusting frequencies based on a comparison between time stamps and oscillator or mixer output. Clock signals are generated for baseband, intermediate and/or RF frequency signal processing. GNSS satellite signals may be demodulated, correlated with a pseudonoise code sequence and/or synchronized based on the time stamps.
