Abstract

A level of interference to a wireless receiver may be controlled by determining a set of frequencies to be assigned to a wireless transmitter, responsive to a power level associated with the wireless transmitter. The set of frequencies is then assigned to the wireless transmitter. Related systems, methods and devices are described.

Claims

1. A method of controlling a level of interference to a wireless receiver, the method comprising:

determining a set of frequencies to be assigned to a wireless transmitter responsive to a power level associated with the wireless transmitter; and

assigning the set of frequencies to the wireless transmitter;

wherein determining comprises increasing a frequency distance between the set of frequencies and a band of frequencies used for reception by the wireless receiver as the power level increases; and

wherein determining further comprises decreasing a frequency distance between the set of frequencies and a band of frequencies used for reception by the wireless receiver as the power level decreases.

2. A method according to claim 1 wherein increasing comprises monotonically increasing a frequency distance between the set of frequencies and the band of frequencies used for reception by the wireless receiver as the power level increases.

3. A method according to claim 1 wherein decreasing comprises monotonically decreasing a frequency distance between the set of frequencies and a band of frequencies used for reception by the wireless receiver as the power level decreases.

4. A method according to claim 1 wherein the set of frequencies is in a satellite band of frequencies.

5. A method according to claim 1 wherein the wireless receiver is a wireless transceiver and wherein determining is further responsive to a detection of a signal from the wireless transceiver.

6. A method according to claim 5 wherein the detection is performed by a base station serving the wireless transmitter.

7. A system for controlling a level of interference to a wireless receiver, the system comprising:

a wireless transmitter; and

a controller that is configured to determine a set of frequencies to be assigned to a wireless transmitter responsive to a power level associated with the wireless transmitter;

wherein the controller is further configured to increase a frequency distance between the set of frequencies and a band of frequencies used for reception by the wireless receiver as the power level increases; and

wherein the controller is still further configured to decrease a frequency distance between the set of frequencies and a band of frequencies used for reception by the wireless receiver as the power level decreases.

8. A system according to claim 7 wherein the controller is configured to monotonically increase a frequency distance between the set of frequencies and a band of frequencies used for reception by the wireless receiver as the power level increases.

9. A system according to claim 7 wherein the controller is configured to monotonically decrease a frequency distance between the set of frequencies and a band of frequencies used for reception by the wireless receiver as the power level decreases.

10. A system according to claim 7 wherein the set of frequencies is in a satellite band of frequencies.

11. A system according to claim 7 wherein the wireless receiver is a wireless transceiver and wherein the controller is further configured to determine the set of frequencies responsive to a detection of a signal from the wireless transceiver.

12. A system according to claim 11 wherein the detection is performed by a base station serving the wireless transmitter.
