Abstract: A wireless characteristic of a wireless signal may be used to trigger generation of a position fix. A mobile computing device may include a wireless transceiver, a location determination circuit and a processing circuit. The wireless transceiver may be configured to receive a wireless signal over a short range wireless network from a wireless system. The processing circuit may be configured to detect a change in the wireless signal and, in response to the detected change, to generate a position fix using the location determination circuit.

Abstract: A mobile computing device comprises a memory, a processor and a transceiver. The memory is configured to store at least one type of position assist data. The processor is configured to provide a position fix based on the position assist data. The transceiver is configured for wireless communication. The memory is configured to store updated position assist data for the type of position assist data. The processor is operable in a first operating mode in which the type of position assist data is not updated and operable in a second operating mode in which the type of position assist data is updated in response to at least one triggering event.
