A method for calibrating signal transmission equipment. The equipment includes at least two signal transmission subsystems, a first subsystem implementing a first signal transmission technology and a second subsystem implementing a second signal transmission technology. The method includes transmitting, by the first subsystem, a signal at a predetermined transmission power; measuring, by the second subsystem, an amount of noise perceived on at least one channel associated with the second subsystem; and recording, in a data structure, the amount of noise for the at least one associated channel.
