  • Patent number: 7929907
    Abstract: A remote satellite modem, in conjunction with a mediation device configuration propagates frames over a cellular backhaul link so as to preserve PRC traceability by receiving a frame based signal, in which the frame based signal conforms to a hub timing signal operable to demarcate frames in the frame based signal, and identifies a start of frame in the received frame based signal, such that the start of frame is independent of the symbol timing of the hub timing signal. In response to the start of frame, the modem generates a timing packet corresponding to a remote timing signal, and forwards the timing packet and the frame based signal, in which the timing packet is for decoding the frame based signal corresponding to the hub timing signal using the remote timing signal.
    Type: Grant

  • Patent number: 7072296
    Abstract: Wireless network demands continually increase as wireless service providers pursue additional service capabilities. In a cellular communication system, leased lines between remote cell sites and the corresponding Mobile Switching Offices (MSOs) remain a major operating cost. Bandwidth reduction by identification and elimination of payload data and control information which need not be fully replicated because it can be deduced from information accessible or previously transmitted allows fewer lines to support the same bandwidth. A wireless access gateway is operable to aggregate such redundant and regenerable data on a backhaul link between a wireless cell site and the corresponding mobile switching office (MSO) to provide low-latency, type specific lossless bandwidth reduction. The wireless access gateway identifies regenerable information and eliminates portions of the data which the device need not transmit because the data is redundant, or accessible or recreatable, at the receiving side.
