1. A mobile computing device comprising:
- a wireless transceiver;
a processing circuit comprising a host processor and a radio processor which are distinct processing components, the processing circuit 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, while the host processor is configured to operate in a reduced power mode, to compare the detected wireless access point identifier to the identified wireless access point, and to initiate location determination based on the comparison, wherein the host processor is configured to switch to a normal power mode in response to the initiation of location determination based on the comparison.
