Abstract

The present invention provides methods, apparatuses and a program relating to detecting passive intermodulation in broadband communication. The present invention includes transmitting, at a base station, a first signal at a first centre frequency and a second signal at a second centre frequency with a predetermined transmit power, capturing, at the base station, received signal at a reception frequency, obtaining, at the base station, a delay between the transmitted signal and a passive intermodulation caused received signal.
