    Abstract: A method an apparatus for selecting a forward link and return link data rate for a constant power, variable data rate two-way, mobile satellite communications link. The forward link and return link signal strength (in the form of carrier power to noise power spectral density ratio) is measured, cataloged, and the values are used for the data rate selection. In addition, a ping can be sent by the network operation center to the mobile unit and the response to the ping is used for updating the information of both forward link and return link signal strength, so the chance of wrong data rate selection can be reduced. Multiple re-transmission attempts combined with gradually increased retransmission margin ensures the proper data rate decision can be eventually achieved even with occasionally inaccurate signal strength information.

    Abstract: A self-correcting mobile antenna control system and method. A method is provided for controlling the direction of an antenna mounted on a vehicle. The method includes determining a position decision based on a direction change signal output from a direction sensor, determining an energy decision based on a signal strength indicator, combining the position decision and the energy decision to produce an antenna control signal, and adjusting the antenna's direction based on the antenna control signal. The system also operates to periodically calibrate itself to offset any sensor errors so that intensive calibration procedures can be avoided.

    Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). A physical layer frame is generated. The frame being used for wireless M2M communications on a forward link in the M2M wireless WAN. The frame including no more than three channels. The physical layer frame including a first channel including paging channel, a second channel including a traffic channel, and a third channel including an acknowledgment (ACK) channel. A time division multiplexing (TDM) operation is performed on pilot symbols and data symbols to obtain a TDM pilot burst. At least one TDM pilot burst is inserted into each channel of the physical layer frame. The physical layer frame is transmitted on the forward link at a low data rate.
