I could be wrong, but I think 2.4 Gig is the lowest frequency range used 
by cell phones in NA, and the sites use antennas with a very narrow 
vertical pattern, designed to shoot over the heads of folks in the near 
field. Unless one of the antennas is very close and fairly low with 
respect to the victim, the most likely RFI would seem to be radiated by 
poorly shielded electronics or power supplies. The latter is what I'd 
expect the power guys to know about.
