Gain measurement and monitoring for wireless communication systems
First Claim
1. A method of monitoring at least one signal repeating element implemented in a wireless communication system, the method comprising:
- obtaining an operational noise measurement in a signal path of the operating signal repeating element by measuring an operational noise level in a frequency band that is outside of a bandwidth of a first device in the signal path of the signal repeating element, but that is also within a wider bandwidth of a second, subsequent device in the same signal path;
retrieving a stored parameter that includes a previously determined reference noise level for the signal repeating element; and
comparing the measured operational noise level to the retrieved parameter and using the comparison to evaluate the gain of at least a section of the signal repeating element to determine a failure or malfunction of a device in the signal repeating element.

Abstract
A method of monitoring an element in wireless communication system is provided. An operational noise measurement is obtained by measuring a noise value outside of a bandwidth of a first device, but within a bandwidth of a second, subsequent device. The operational noise measurement is alternatively obtained by tuning an input band of the element to shift the input band partially or completely outside of a bandwidth of a first device to create an open band or by suppressing an input of the antenna and measuring noise within the open bandwidth of the element of the wireless communication network. A stored parameter is retrieved and compared to the measured operational noise. Alternatively, a leakage signal of the element may be received at a signal receiver and compared to a reference. The reference is a function of components of the wireless communication system in a leakage path of the leakage signal.
