Sorry dirtybird, but yours sounds like a layman's understanding of 2.4Ghz operations; just enough knowledge to get into trouble.

My brother was an electronics tech, and we would experiment for fun with different devices, from synthesizers to radar jammers. One predicate I learned in HS electronics is that ANY frequency can be jammed/swamped if one has enough power (wattage). I found this to be the case with police radar when it was first introduced.

Heli fliers on another popular site first noticed the odd phenomenon years ago. When their smart phones rang while on the flight line, and nearby helis would get suddenly skittish, they put 2+2 together and banned cell phones on the flight line. It seems that phones put out the strongest signal when making or ending a call. It wouldn't happen every time, but enough to give notice. Keeping cells off the flight line, or back inside the car, seemed to be the solution.
