Way it was explained to me (when I was working at a wireless phone company) was that all the towers that can "see" the phone arbitrate to decide who has the best signal, and when to hand off.

Not such a big deal when you're driving up the freeway @ 55 MPH and two or maybe three towers are involved, but significant when you can "see" a 100 towers or more, and are moving @ 600 knots to boot, and then multiply that by 50+ phones on the aircraft...

If there's effectively a tower on the aircraft, it's a slam dunk for the phone, it only talks to that...

Heck yes. It's bad enough that no airline provides a "no children" area, much less service. Yet.

I love children, but I couldn't eat a whole one...
