1. A mobile computing device, comprising:
- a wireless transceiver configured to receive a wireless signal over a short range wireless network from a wireless system;
a location determination circuit including at least one member of the group consisting of a global positioning satellite (GPS) receiver, an access point, and a cellular receiver;
a memory resource;
a display; and
a processing circuit to;
(i) determine whether there is a change in the wireless signal, (ii) in response to determining that there is a change in the wireless signal, generate a position fix using the at least one member of the group consisting of the GPS receiver, the access point, and the cellular receiver of the location determination circuit, (iii) in response to generating the position fix, store the position fix and an identifier of the wireless system in the memory resource, and (iv) control the display based on the position fix and the identifier of the wireless system.

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.

9. A method for generating a position fix for a mobile computing device, the method being performed by one or more processors and comprising:
-
receiving a wireless signal over a short range wireless network from a wireless system via a wireless transceiver of the mobile computing device; determining whether there is a change in the wireless signal; in response to determining that there is a change in the wireless signal, generating a position fix using at least one member of the group consisting of a global positioning satellite (GPS) receiver, an access point, and a cellular receiver provided within a location determination circuit; in response to generating the position fix, storing the position fix and an identifier of the wireless system in a memory resource of the mobile computing device; and controlling a display of the mobile computing device based on the position fix and the identifier of the wireless system. - View Dependent Claims (10, 11, 12, 13, 14)
