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.
