Abstract
A system and method of extending the range of a vehicle telematics unit includes determining that a vehicle telematics unit is outside of a geographic range beyond which time division multiple access (TDMA) transmissions sent from the vehicle telematics unit to a base station arrive at the base station after a time slot allocated to the vehicle telematics unit in a time frame has passed; calculating a time delay that causes the TDMA transmissions to arrive at the base station in the allocated time slot of a subsequent time frame; and sending TDMA transmissions from the vehicle telematics unit at a time determined using the time delay.
