Clear as mud :)
Something to consider is there are a lot of call/PCS/whatever you want
to call them phones out there that can use all three modes: AMPS,
~900MHz digital (PCS), and 1800MHz digital. Most people do not
understand the difference, let alone what the "A" or "D" indicators on
their phone mean.
Something else to consider, some handsets inadvertently radiate
off-frequency.
The last thing to consider, can a 0.6W (or less) transmission, coming
from within the fuselage, on its intended or unintended frequency (or a
harmonic), realistically interfere with UHF/SHF band avionics
(transponder/TCAS, GPS come to mind)? Pretty unlikely.
That was a mouthful. :)
I always turn off my phone on airliners, but usually forget and leave it
on when I am flying light aircraft. Flying over BFE for more than a few
hours usually kills the battery anyway.
The airlines are moving towards allowing people to use wireless phones
and Blackberrys in flight.
