  • EXTENSION OF A LOCAL AREA PHONE SYSTEM TO A WIDE AREA NETWORK WITH HANDOFF FEATURE
    Publication number: 20120069754
    Abstract: A soft switch 134 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.

  • Active cancellation tuning to reduce a wireless coupled transmit signal
    Patent number: 6915112
    Abstract: An active cancellation controller receives a signal strength indicator that indicates a power level of a coupled signal from a local wireless transmitter at a local wireless receiver. The active cancellation controller tunes an active cancellation circuit to reduce the signal strength indicator. The active cancellation circuit is to generate a cancellation signal to combine with the coupled signal at the local wireless receiver.
