Abstract

Claims (34)

1. A method for detecting uplink capacity of a repeater within a wireless network, the repeater having a server antenna and a donor antenna, the method performed on a computer have at least one processor, the method comprising:

determining, by the at least one processor, the maximum gain of the server antenna in a downlink direction, the determination performed in response to transmissions in the uplink direction being turned off;

measuring the uplink transmission power level at an input to the server antenna of the repeater;

measuring the uplink transmission power level at an input to the donor antenna of the repeater;

determining, by the at least one processor, whether the uplink transmission power level measured at the donor input is greater than, or equal to, the maximum uplink power level;

calculating, by the at least one processor, the uplink gain based on the difference between the uplink transmission power level at the donor input and the uplink transmission power level at the server input;

determining, by the at least one processor, whether the calculated uplink gain is less than the maximum gain in a downlink direction; and,

generating, responsive to a determination that the calculated uplink gain is less than the maximum gain in the downlink direction, a notification of a power error condition.

2. The method as in claim 1 , further comprising:

disabling the repeater in response to the generated notification of a power error condition.

3. The method as in claim 1 , further comprising:

increasing the power allocated to the uplink transmission in response to the generated notification of a power error condition.

4. The method of claim 1 , wherein measuring the uplink transmission power level at the server input provides an indication whether the uplink is active.

5. The method of claim 4 , wherein, responsive to a determination that the uplink is inactive, repeating the step of measuring the uplink transmission power level at the server input.

6. The method of claim 4 , wherein responsive to a determination, by the at least one processor, that the uplink transmission power level measured at the donor input is less than the maximum uplink power level, the method further comprises repeating the step of measuring the uplink transmission power level at the server input.

7. The method of claim 1 , wherein responsive to a determination, by the at least one processor, that the uplink gain is greater than, or equal to, the downlink gain, the method further comprises repeating the step of measuring the uplink transmission power level at the server input.

8. The method of claim 1 , further comprising:

outputting the notification of the power error condition.

9. A repeater for retransmitting wireless signals comprising:

a server input configured to receive and transmit signals between the repeater and one or more wireless devices, the transmitted signals including uplink transmissions and downlink transmissions, the server input comprising a sensor configured to measure the transmission power of the uplink transmissions at the server input;

a donor input configured to receive and transmit signals between the repeater and a base station, the transmitted signals including uplink transmissions and downlink transmissions, the donor input comprising a sensor configured to measure the transmission power level of the uplink transmissions at the donor input; and,

at least one physical computer processor configured to:

determine the maximum gain of the server antenna at the server input, the determination performed in response to a transmission in the uplink direction being turned off;

determine whether the uplink transmission power level at the donor input is greater than, or equal to, a maximum uplink power level at the server input;

calculate the uplink gain based on the difference between the uplink transmission power level at the donor input and the uplink transmission power level at the server input;

determine whether the calculated uplink gain is less than the maximum gain in a downlink direction at the server input; and,

generate, responsive to a determination that the calculated uplink gain is less than the maximum gain in the downlink direction, a notification of a power error condition.

10. The repeater as in claim 9 , wherein the at least one physical computer processor is further configured to disable the repeater in response to a notification of a power error condition.

11. The repeater as in claim 9 , wherein the further at least one physical computer processor is further configured to increase the power allocated to the uplink transmission in response to a notification of a power error condition.

12. The repeater as in claim 9 , wherein measuring the uplink transmission power level at the server input provides an indication whether the uplink is active.

13. The repeater as in claim 12 , wherein, responsive to a determination that the uplink is inactive, the at least one physical computer processor is further configured to repeat the step of measuring the uplink transmission power level at the server input.

14. The repeater as in claim 12 , wherein, responsive to a determination that the uplink transmission power level measured at the donor input is less than the maximum uplink power level, the at least one physical computer processor is further configured to repeat the step of measuring the uplink transmission power level at the server input.

15. The repeater as in claim 9 , wherein, responsive to a determination that the uplink gain is greater than, or equal to, the downlink gain, the at least one physical computer processor is further configured to repeat the step of measuring the uplink transmission power level at the server input.

16. The repeater as in claim 9 , wherein, responsive to generation of a notification of a power error condition, the one or more physical computer processors may be further configured to output the notification.
