1. A mobile computing device comprising:
- a wireless transceiver;
a processing circuit including a radio processor and a host processor; and
a memory storing instructions that, when executed by the processing circuit, cause the mobile computing device to;
identify at least one wireless access point identifier from a database of wireless access point identifiers;
detect a local wireless access point identifier using the wireless transceiver;
compare the detected local wireless access point identifier with the at least one wireless access point identifier while the host processor operates in a reduced power mode; and
switch an operating mode of the host processor from the reduced power mode to a normal power mode based, at least in part, on the comparison.

Abstract
A mobile computing device comprises a wireless transceiver and a processing circuit. The processing circuit is configured to identify a location, to identify a wireless access point within a predetermined distance of the location, to detect a wireless access point identifier using the wireless transceiver, to compare the detected wireless access point identifier to the identified wireless access point, and to initiate location determination based on the comparison.
