Abstract
Official abstract text for this publication.
A communications device includes a housing, an antenna carried by the housing, an oscillator carried by the housing to generate a reference signal, and an RF receiver carried by the housing, and coupled to the antenna and the oscillator, the RF receiver demodulating a received signal from the antenna based upon the reference signal. The communications device also includes a GPS receiver carried by the housing to generate a calibration signal, a temperature sensor carried by the housing to generate a sensed temperature value, and a processor carried by the housing and coupled to the oscillator, the RF receiver, the GPS receiver, and the temperature sensor. The processor may enter an oscillator calibration mode based upon the sensed temperature value for selectively calibrating the oscillator based upon the calibration signal.
