Abstract: A method for reducing power consumption in a transceiver front-end circuit for a cellular radio. The transceiver circuit includes a receiver module having a delta-sigma modulator that converts analog receive signals to a representative digital signal in an interleaving process, where the delta-sigma modulator includes a combiner, a low noise amplifier (LNA), an LC filter and a quantizer circuit. The LC filter is a multi-order filter and the quantizer circuit is an interleaving quantizer circuit that interleaves multiple groups of bits from the filter. The method includes selectively reducing the order of the LC filter in situations where a full dynamic range of the cellular radio is not required and reducing a bit resolution of the quantizer circuit so as to reduce the power requirements of the cellular radio.

Abstract: A TPMS that uses a unique signature, such as RSSI signal levels and statistics or Doppler shift information, to identify the location of where the TPMS signal is being transmitted from. The TPMS includes a separate transmitter unit provided in each tire, where each transmitter unit transmits TPMS signals including an ID code identifying the tire and the pressure in the tire. The TPMS also includes a receiver unit that receives the TPMS signals from each of the transmitter units, where the receiver unit stores an average or other classification of the signature over time to identify the location of the transmitter unit for a particular ID code. The receiver unit compares the new received TPMS signals to the classified signals to identify whether the ID code indicates that the position of the tire has changed.

Abstract: A method of controlling data communication between a vehicle and a plurality of wireless networks includes tracking a location of the vehicle over time to identify a known route, and tracking a signal duration for each of the plurality of wireless networks. One of the plurality of wireless networks that provides the longest signal duration for the vehicle, and which is available for data communication with the vehicle along the identified known route, is identified. When a current route of the vehicle is the same as the known route, data communication from the vehicle is connected to the available wireless network identified as providing the longest signal duration for the vehicle when moving along the identified known route.
