Each electromagnetic source has it’s own characteristic sound, which is demodulated by broadband-meters to allow evaluating the source from the sound. Although GSM-900 and GSM-1800 can’t be differentiated by their sound as it is the same. Other sources are easily detectable, here are a couple of examples. If you’d like to listen to some other source, please contact us.
