Abstract
A method, and related apparatus, for detecting interference at a first communications terminal comprising establishing a communications link between the first communications terminal and a second communications terminal. Then monitoring a noise floor of the communications link over time, the noise floor representing a base level of noise present in the communications link and calculating a long term noise floor power level without interference in response to the monitoring of the noise floor of the communications link over time. Then monitoring a noise floor of a current communication through the communications link, representing a current level of noise present on the communications link and calculating a short term noise floor power level in response to the monitoring of the noise floor of the current communication through the communications link. Finally, comparing the short-term noise floor power level with the long term noise floor power level without interference.
