No. They are the same thing. In Britain, what you call a cell phone, is called a mobile phone. The CAA mean cell-phones not walk-around-the-house style things.
> Imagine the area of towers you could hit at 30,000ft in the sky
Quite a few, if the signal was strong enough to travel 30,000 feet. That's 10,000 yards. Which in (British at least - don't know about US) miles, is about 5.5 miles. This might work along the ground, but straight up in the air???
I worked for a while almost at the top of the new HSBC building in London's Docklands. It's only a little shorter than Canada Tower (Britain's tallest building), but above about the 40th floor, you lose your phone signal and can only intermittently make calls.
Therefore, I think that the danger comes not from communicating with cells, but the phones continually searching for cells (which does involve transmission I believe). They do this every few seconds. An unscientific way of showing this is when you are out of range, the battery life of phones left on standby reduces dramatically, due to all the extra transmissions.
