Abstract
A location-enabled wireless device includes a wireless receiver and a positioning-signal receiver. The wireless device further includes an oscillator adapted to output a reference-frequency signal to the wireless receiver and the positioning-signal receiver and a detector adapted to output a control signal upon detection of at least one of a frequency error and a phase error between wireless signals and the reference-frequency signal. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
Claims23
A location-enabled wireless device comprising:
- a wireless receiver;
- a positioning-signal receiver;
- an oscillator adapted to output a reference-frequency signal to the wireless receiver and the positioning-signal receiver;
- and
- a detector adapted to output a control signal upon detection of at least one of a frequency error and a phase error between wireless signals and the reference-frequency signal.
A method of reducing a time to fix in a location-enabled wireless device, the method comprising:
- receiving wireless signals;
- receiving positioning signals;
- outputting of a reference-frequency signal to a wireless receiver and a positioning-signal receiver;
- responsive to detection of at least one of a frequency error and a phase error between wireless signals and the reference-frequency signal, outputting a control signal;
- and
- wherein the control signal provides an indication that the reference-frequency signal is being updated.
