  • Patent number: 7852581
    Abstract: PMR spacing is measured by writing a pattern on a magnetic storage layer in non-return-to-zero notation, reading the pattern from the magnetic storage layer, analyzing a first harmonic component of the pattern that has a first amplitude, analyzing a second harmonic component of the pattern that has a second amplitude, measuring a ratio between the first and the second amplitudes of the first and second harmonic components, and determining a first spacing based on the ratio. In another embodiment, spacing is measured by analyzing a third harmonic component on the magnetic storage layer that has a third amplitude, measuring a difference in the amplitudes of the second and the third harmonic components while varying the first spacing and taking the ratio of the difference of the two each harmonic components.

  • Patent number: 7844281
    Abstract: Emergency Services architecture for determining the location of a wireless caller. The architecture leverages a synchronization feature of GSM networks of the Base Station Subsystem (BSS) to enable employment of sparse networks by removing WLS (Wireless Location Sensor) equipment from selected cell sites. Thus, the location of a wireless caller within a sparse site can be determined. Sparse network location services can be provided further utilizing Time Difference of Arrival (TDOA) technology, and other network-based location technologies such as Enhanced Observed Time Difference (EOTD) and Angle of Arrival (AOA). Hybrid network-based/handset-based location technologies may also be used with the disclosed invention.

  • Patent number: 7826868
    Abstract: A soft switch providing wireless PBX voice services to a local area network (WLAN) is used to extend PBX functionality to the cellular domain. A dual mode remote unit is capable of receiving signals both in the cellular system as well as the WLAN. The cellular system is comprised of a data-bearing path and a voice-bearing path. When the dual mode remote unit is within the WLAN, it communicates both voice over IP (VoIP) signaling as well as session initiation protocol (SIP) control signaling over the WLAN. When the remote unit is outside the WLAN, it communicates voice signaling over the voice-bearing path of the cellular network using a standard cellular voice channel. In parallel, it uses the data-bearing path of the cellular network to transmit SIP control signaling.

  • Patent number: 7792533
    Abstract: A cellular communication system comprises a set of base stations (201,203) which transmit downlink resource exchange discovery messages to remote terminals in resource allocations of a Media Access Control, MAC, frame structure. The discovery messages may indicate that a base station has resource available for reallocation to another base station or that a base station is seeking resource to be allocated from another base station. A remote terminal (205) comprises a receiver (401, 403) which receives a first message of the downlink resource exchange discovery messages from at least a first base station (201). A discovery message transmit processor (407) generates a second message, which is an uplink resource exchange message comprising resource exchange data determined from the first message, and transmits this to a second base station (203). The second base station (203) then initiates a temporary air interface resource reallocation with the first base station in response to receiving the second message.
