Bollocks it could. If that was the case someone standing next to the BTS would knock out everyone else using it. You might confuse the cellular network, but you won't 'drown out' anything.

A GSM phone has a 2 watt transmitter.
Sutton Coldfield is a TV and radio transmitter station, near Birmingham in the UK. It puts out a million watts on TV, and 250,000w on FM radio i.e. at least 125,000 times the power of a phone.
Sutton Coldfield is fairly near Birmingham airport, which has a radar system. I don't know the output of it, but it will be several kilowatts.
A mobile phone's output is insignificant compared to them, and yet planes don't fall out of the sky.
