Apparatus and method for maintaining communication with a stolen vehicle tracking device
First Claim
1. A method of maintaining communications between a base station and a stolen vehicle tracking (SVT) module disposed with a vehicle, the method comprising:
- at the stolen vehicle tracking (SVT) module at the vehicle;
determining whether jamming is occurring with communications between the SVT module and the base station,measuring a temperature at the SVT module;
when jamming is detected, determining an adjustment for a frequency of an oscillator of the SVT module, the adjustment based at least in part upon the temperature;
adjusting the frequency of operation of an oscillator according to the adjustment;
transmitting a message to the base station according to the adjusted frequency.

Abstract
Communications are maintained between a base station and a stolen vehicle tracking (SVT) module disposed with a vehicle. At the SVT module at the vehicle, it is determined whether jamming is occurring with communications between the SVT module and the base station and a temperature is measured at the SVT module. When jamming is detected, an adjustment is determined for a frequency of an oscillator of the SVT module and the adjustment is based at least in part upon the temperature. The frequency of operation of an oscillator is adjusted according to the adjustment. A message is transmitted to the base station according to the adjusted frequency.
