Abstract

A power control device for adjusting power output levels can include a transmitter configured to transmit at least one first signal, and a receiver configured to receive at least one second signal. In addition, the power control device can have a processing unit configured to determine at least one location information based on the first signal and the second signal, and a power adjusting unit configured to adjust a power output level corresponding to the at least one location information.

Claims

1. A method of adjusting power output of a device in a wireless network, said method comprising the steps of:

activating a power control device;

transmitting a first signal from the power control device;

receiving a second signal at the power control device;

determining a location information on at least one wireless device based on the first signal and the second signal; and

adjusting a power output level corresponding to the location information.

2. The method of claim 1, further comprising the step of:

transmitting a third signal from the power control device at the adjusted power output level.

3. The method of claim 2, wherein the step of transmitting a first signal comprises the step of:

transmitting the first in pulses at a predetermined power level.

4. The method of claim 3, further comprising the step of:

adjusting the power output level when a predetermined period of time has lapsed.

5. The method of claim 3, further comprising the step of:

adjusting the power output level when the second signal contains an amount of errors equals to or exceeds a predetermined threshold.

6. The method of claim 3, further comprising the step of:

adjusting the power output level when the second signal contains a power saturated signal.

7. The method of claim 1, wherein the step of determining the location information comprises the steps of:

determining at least one distance range information; and

determining at least one geographic position information.

14. The power control device of claim 7, wherein the processing unit is configured to determine at least one distance range based on the first signal and the second signal;

and wherein the processing unit is configured to determine at least one geographic position based on the first signal and the second signal.

8. A power control device for adjusting power output levels of a device in wireless network, said power control device comprising:

a transmitter configured to transmit a first signal;

a receiver configured to receive a second signal;

a processing unit configured to determine a location information on at least one wireless device based on the first signal and the second signal; and

a power adjusting unit configured to adjust a power output level corresponding to the location information.

9. The power control device of claim 8, wherein the transmitter is configured to transmit a third signal from the power control device at the adjusted power output level.

10. The power control device of claim 9, wherein the transmitter is configured to transmit the first signal in pulses at a predetermined power level.

11. The power control device of claim 10, wherein the power adjusting unit is configured to adjust the power output level when a predetermined period of time has lapsed.

12. The power control device of claim 10, wherein the power adjusting unit is configured to adjust the power output level when the second signal contains an amount of errors equals to or exceeds a predetermined threshold.

13. The power control device of claim 12, wherein the power adjusting unit is configured to adjust the power output level when the second signal contains a power saturated signal.

15. A system for adjusting power output of a wireless device in a wireless network, said system comprising:

an activating means for activating a power control device;

a transmitting means for transmitting a first signal from the power control device;

a receiving means for receiving a second signal at the power control device;

a determining means for determining a location information on at least one wireless device based on the first signal and the second signal; and

an adjusting means for adjusting a power output level corresponding to the location information.

16. The system of claim 15, wherein the transmitting means transmits a third signal at the adjusted power output level.

17. The system of claim 16, wherein the transmitting means transmits the first signal in pulses at a predetermined power level.

18. The system of claim 17, wherein the adjusting means adjusts the power output level when a predetermined period of time has lapsed.

19. The system of claim 17, wherein the adjusting means adjusts the power output level when the second signal contains an amount of errors equals to or exceeds a predetermined threshold.

20. The system of claim 17, wherein the adjusting means adjusts the power output level when the second signal contains a power saturated signal.

21. The system of claim 15, wherein the determining means determines at least one distance range information, and wherein the determining means determines at least one geographic position information.

22. A method of controlling transmission signal levels of a device in a wireless network, said method comprising the steps of:

determining a location information of a device; and

transmitting a signal for controlling transmission signal levels of the device, wherein the transmission signal levels do not cause transmission interference.

23. A transmission signal level controlling device for controlling the transmission signal levels of a device in wireless network, said device comprising:

a determination unit configured to determine a location information of a device; and

a transmitting unit configured to transmit a signal to adjust transmission signal levels of the device, wherein the transmission signal levels do not cause transmission interference.

24. A system for controlling transmission signal levels of a wireless device in a wireless network, said system comprising:

a determining means for determining a location information of a device; and

a transmission means for transmitting a signal for controlling transmission signal levels of the device, wherein the transmission signal levels do not cause transmission interference.
