But don't you think it's funny that you can use a cell phone in the airport but not on the plane? With the broadcasted signal, incoming flights and out going flights should be affected too, even though the person might not physically on the plane, the signal is everywhere!!!
You bring up a good point actually.
The signal can reflect quite a ways. However the issue AFAIK would be plane to ground, not ground to plane. On the ground they have "unlimited" power to transmit a signal that can reach the aflicted area that particular airport needs to cover. From the plane however, there is not, and sometimes the signal needs to be broadcasted quite a ways away, and from however high up, to the ground.
Interference can cause trouble, and even devices like Wifi which broadcast in a specific frequency can potentially put out interference on frequencies it was not designed to broadcast at.
Now really the FAA and FCC kind of overhype the issue, but communication is really important, because there is information about weather, airport closures, emergency stuff, and the most important part, landing (so you don't land on top of another plane).
Back to the power, on the ground they can broadcast with way more power than any Bluetooth and Wifi device, more than enough to break by any interference. But on the plane it could be a different issue, what with limited power availability and all.
