ABSTRACT:
A method (300) of extending battery life in a communication device having a plurality of receivers includes receiving information with a primary receiver that is configured to operate on a first network (303) and controlling a secondary receiver that is configured to operate on a second network that is independent from the first network in accordance with the information obtained with the primary receiver. A corresponding communication device (201) includes: a primary receiver (221) configured to operate on a first network (203); a secondary receiver (227, 233) configured and arranged to operate as a short range receiver with an access point (205, 207) that is independent of the first network; and a controller (225, 231, 237) that is configured to control the secondary receiver in accordance with information obtained from the primary receiver.
