Systems and methods for adjusting system tests based on detected interference
First Claim
1. A method for testing a distributed antenna system (DAS), the method comprising:
- disabling generation of at least one tone, where the at least one tone is transmitted to a remote antenna unit;
measuring at least one of the reverse power and the forward power at the remote antenna unit;
determining whether the remote antenna unit is receiving an interfering signal based on at least one of the measured reverse power and the measured forward power; and
adjusting at least one subsequent system test based on the determination of whether the remote antenna unit is receiving an interfering signal.

Abstract
Embodiments of the present invention provide improved systems and methods for adjusting system tests based on detected interference. In one embodiment, a system comprises a host unit; a system test controller to control the performance of system tests, wherein a system test to detect the reception of an interfering signal comprises disabling the generation of tones for transmission through the communication system. The system also comprises multiple remote antenna units communicatively coupled to the system test controller to transmit signals to multiple wireless terminals, wherein a remote antenna unit comprises: an antenna; a transceiver, coupled to the antenna; a signal detector that measures reverse and forward power of signals transmitted to and received from the antenna; and a microcontroller to control the antenna unit, wherein upon receiving a command to perform interference testing, the microcontroller adjusts a subsequent test based on measurements of the reverse power by the signal detector.
