Planes & Cell phones

Huh? Maximum output of most handheld cell phones is 0.6 watts with the old
in-car and bag phones going up to 3 watts. It can't output more than it's
maximum no matter how far you are away from the tower. The radius of
interference from 0.6 watt phones transmitting from inside an aluminum can
would be rather small. And it's a little hard to imagine a plane full of
people with bag phones.

I thought I might just toss this out there. I quickly looked. I did not
have any trouble finding modern, handheld phones, with 2-watts output.
So, I think it's safe to say that we know for sure it's at least 2-watts.

Both of my run-of-the-mill Nokias have a maximum transmit power of 600
mW. They are two different digital/analog models.

Well, that's an interesting point. I know if I leave my phone on in the
air, it tends to degrade to analog mode (dual band phone). While I am
aware the digital mode uses far less power (just didn't realize that
little), perhaps the 5-watt maximum number is representative of phones
operating in analog mode? I dunno. That's my best guess.

0.7 watts is the maximum that is considered "safe" for handheld use by
medical experts. Any more than that gets your brain frying, so they say.
;-)

I've had cell phones for fifteen years (novatel, motorola, mitsubishi, etc.)
and all the handhelds except the ericssons were 0.6 watts. The ericssons
were only 0.5 watts! Way back then I remember if you complained about bad
reception with a handheld they'd tell you to "upgrade" to a transportable.

Any links or names of the ones you found?

All I did was a quick google and this was the first one that popped up.
It says, 2 watts, 1 watts, and 1 watts for it's maximum output for the
three supports networks. It is a tri-band phone.

The second link is a power amplifier which cranks output up to 3-watts.
Keep in mind, just bacause a phone may output less than maximum power,
doesn't have to mean they are not allowed to output higher. Perhaps we're
playing with semantics here. Perhaps the maximum allowed is 5-watts? And
most phones output less? I dunno. At any rate, right off the bat, I
didn't have any trouble finding a phone that has a maximum output of
2-watts.

They almost certainly are not cell phones. Probably PCS.

This marriage is off to a shaky start. The groom just asked the band to
play "Your cheatin' heart", and the bride just requested "Don't come home
a'drinkin' with lovin' on your mind".

I'm using layman's terminology, which would cover PCM, GSM, etc, etc, etc...

Oh, surely not! NOBODY (except me) calls those "cell phones".

Good thing we still have George around to explain this to us. I think we've
lost the brilliant educator Jerry Bransford.
