Abstract

Apparatus having corresponding methods and tangible computer-readable media comprise: a measurement module adapted to generate measurements of a wireless television signal received by the apparatus and measurements of a wireless satellite positioning signal received by the apparatus; a location module adapted to determine a location of the apparatus based on the measurements of the wireless television signal and the measurements of the wireless satellite positioning signal; and a time module adapted to provide a clock control signal for the apparatus based on at least one of the measurements of the wireless television signal, and the measurements of the wireless satellite positioning signal.

Claims

1. An apparatus comprising:

a measurement module adapted to generate measurements of a wireless television signal received by the apparatus and measurements of a wireless satellite positioning signal received by the apparatus;

a location module adapted to determine a location of the apparatus based on the measurements of the wireless television signal and the measurements of the wireless satellite positioning signal;

a time module adapted to provide a clock control signal for the apparatus based on at least one of;

the measurements of the wireless television signal; and

the measurements of the wireless satellite positioning signal;

an oscillator adapted to provide one or more clock signals based on the clock control signal; and

a transceiver adapted to transceive wireless mobile telephone signals based at least one of the clock signals.

2. The apparatus of claim 1, further comprising:

a receiver adapted to receive the wireless television signal and the wireless satellite positioning signal.

3. The apparatus of claim 1, further comprising:

a time base module adapted to provide a periodic time base signal based on one or more of the clock signals;

wherein the transceiver is further adapted to transceive the wireless mobile telephone signals based on the periodic time base signal.

4. The apparatus of claim 1, further comprising:

a network interface adapted to transceive network signals representing the wireless mobile telephone signals.

5. A method comprising:

generating measurements of a wireless television signal received by an apparatus and measurements of a wireless satellite positioning signal received by the apparatus;

determining a location of the apparatus based on the measurements of the wireless television signal and the measurements of the wireless satellite positioning signal;

providing a clock control signal for the apparatus based on at least one of;

the measurements of the wireless television signal; and

the measurements of the wireless satellite positioning signal;

providing one or more clock signals based on the clock control signal; and

transceiving wireless mobile telephone signals based at least one of the clock signals.

6. The method of claim 5, further comprising:

receiving the wireless television signal and the wireless satellite positioning signal.

7. The method of claim 5, further comprising:

providing a periodic time base signal based on one or more of the clock signals; and

transceiving the wireless mobile telephone signals based on the periodic time base signal.

8. The method of claim 5, further comprising:

transceiving network signals representing the wireless mobile telephone signals.

9. Non-transitory computer-readable media embodying instructions executable by a computer to perform a method comprising:

generating measurements of a wireless television signal received by an apparatus and measurements of a wireless satellite positioning signal received by the apparatus;

determining a location of the apparatus based on the measurements of the wireless television signal and the measurements of the wireless satellite positioning signal;

causing the apparatus to provide a clock control signal for the apparatus based on at least one of;

the measurements of the wireless television signal; and

the measurements of the wireless satellite positioning signal;

causing the apparatus to provide one or more clock signals based on the clock control signal; and

causing the apparatus to transceive wireless mobile telephone signals based at least one of the clock signals.

10. The non-transitory computer-readable media of claim 9, wherein the method further comprises:

causing the apparatus to provide a periodic time base signal based on one or more of the clock signals; and

causing the apparatus to transceive the wireless mobile telephone signals based on the periodic time base signal.

11. The non-transitory computer-readable media of claim 9, wherein the method further comprises:

causing the apparatus to transceive network signals representing the wireless mobile telephone signals.
