A method and implementation disclosed for detecting interference. A state machine controller is provided for establishing an interference detection cycle including a power sample period and a periodic sampling interval. A receiver component, responsive to the state machine controller, performs an energy measurement at a predetermined wireless band during the power sample period. A threshold comparator determines whether the energy measurement exceeds a predetermined threshold. A processing implementation processes the energy measurement to determine whether it corresponds to interference on the predetermined wireless band, if the measurement exceeds the predetermined threshold. A deactivating implementation is used to instruct the state machine controller to await the next power sample period, if the energy measurement does not exceed the predetermined threshold.
