[RFI] Fw: cell phone interference on airplanes

[WX5L]

Would someone in the know explain why technically the cell phones in the 
headrest(Verizon?) Airphones don't cause the same problems as customer owned 
cell phones. Why are they immune from causing RFI to the aircraft and also 
from causing massive interference to cell sites below?

Thanks,

Randy
