Abstract

A method of dynamically adjusting a wireless transceiver may include acquiring a geographical location of the wireless transceiver and determining transmission characteristics that are compliant with wireless regulations covering the geographical location. The wireless transceiver may be adjusted to conform to the transmission characteristics, and data may be transmitted with the adjusted wireless transceiver.

Claims

1. A method of dynamically adjusting a wireless transceiver, comprising:

acquiring a geographical location of the wireless transceiver;

determining transmission characteristics that are compliant with wireless regulations covering the geographical location;

adjusting the wireless transceiver to conform to the transmission characteristics; and

transmitting data with the adjusted wireless transceiver.

2. The method of claim 1, further comprising:

storing the geographical location in a memory.

3. The method of claim 1, wherein the acquiring includes:

receiving a global positioning signal with a global positioning system receiver, and

calculating the geographical location from the global positioning signal.

4. The method of claim 1, wherein the acquiring includes:

receiving a wireless area network signal including location information embedded therein.

5. The method of claim 1, wherein the acquiring includes:

receiving a cellular telephone signal including location information embedded therein.

6. The method of claim 1, wherein the determining includes:

looking up the transmission characteristics based on the geographical location.

7. The method of claim 1, wherein the adjusting includes:

changing a transmission frequency or a transmission power of the wireless transceiver.

8. A machine-readable medium having stored thereon instructions, which if executed by a machine causes the machine to perform a method comprising:

determining a geographical location of the machine;

ascertaining transmitter characteristics that are compliant with regulations in a regulatory area based on the geographical location; and

adjusting a wireless transceiver to wirelessly transmit data according to the transmitter characteristics.

9. The medium of claim 8, further comprising instructions, which if executed by a machine causes the machine to perform:

storing the geographical location.

10. The medium of claim 8, wherein the determining includes:

determining the geographical location based on a received global positioning system signal.

11. The medium of claim 8, wherein the determining includes:

determining the geographical location based on a received radio frequency signal having location information embedded therein.

12. The medium of claim 8, wherein the ascertaining includes:

finding the regulatory area that includes the geographical location, and

looking up the transmitter characteristics based on the regulatory area.

13. The medium of claim 8, wherein the adjusting includes:

setting a transmission frequency and a transmission power for the wireless transceiver.

14. A system to wirelessly transmit data, comprising:

a first transceiver to extract a geographical location of the system from a received signal;

a second adjustable transceiver to wirelessly transmit data in accordance with input transmission parameters;

a memory to store a set of transmission parameters that is indexed by geography; and

a processor connected to the first transceiver, the second adjustable transceiver, and the memory to choose the input transmission parameters from the set of transmission parameters based on the geographical location of the system and to adjust the second adjustable transceiver with the input transmission parameters.

15. The system of claim 14, wherein the first transceiver is arranged to extract the geographical location from a received global positioning system signal.

16. The system of claim 14, wherein the first transceiver is arranged to extract the geographical location from a received radio frequency signal.

17. The system of claim 14, wherein the second transceiver is arranged to wirelessly transmit data according to a wireless area network protocol.

18. The system of claim 14, wherein the second transceiver is arranged to wirelessly transmit data according to a cellular communication protocol.

19. The system of claim 14, further comprising:

an antenna coupled to the first transceiver or the second adjustable transceiver.

20. The system of claim 14, wherein the processor is further arranged to store the geographical location of the system in the memory.

21. The system of claim 14, further comprising:

a third adjustable transceiver to wirelessly transmit data in accordance with other transmission parameters using a communication protocol different from the second adjustable transceiver,

wherein the processor is further arranged to choose the other transmission parameters from the set of transmission parameters based on the geographical location of the system and to adjust the third adjustable transceiver with the other transmission parameters.

22. The system of claim 14, wherein the input transmission parameters include one or more transmission frequencies or channels.

23. The system of claim 22, wherein the input transmission parameters further include one or more transmission powers.
