A communications apparatus capable of detecting a signal transmitted by another apparatus in a first band of spectrum is described. The apparatus identifies at least one second band of spectrum, different from the first band of spectrum, in which no signal is detected and then determines a noise characteristic for the at least one second band of spectrum. The determined noise characteristic may then be used by an energy detector operating in the first band of spectrum to ensure reliable detection of signals transmitted by the other apparatus.
