My father got his first cell-phone in the mid-eighties...
All right, it weighed in at several kilos and was nearly as big as an attache case(It was an NMT450 analog system), but as he was driving a JCB at the time, he had the power to transport it...
weren't those classed as "mobile phones" as opposed to cellular!?

every year my family would vacation in montegue, la. (there were no phones in the camp)
in august 2001 (and for several preceding years) there was a single carphone in a leather carrying case that was 12" long.... the next year, august 2002, there were 8 cellphones for 12 people charging on the kitchen table.
i'm sure different areas may have experienced the cellular revelution differently, but thats how it happened in louisiana

I bought my first phone in 1996. It was a Nokia 2110 (possibly named 2190 in the USA) and was considered the best on the market back then. (Nokia introduced the 'banana'-phone, 8110 the same year)
It lasted me until 2002 when it was damaged by water condensation.
And I recently got ahold of another 2110 to use in my car as the modern junk has too poor reception. (Besides, I have a good hands-free set for the 2110)
haha....I wonder if they realized the dangers of RF emissions exposure and maybe that's why your old phone works better!

Yesterday's NPR "All Things Considered" has a story of the difficulty of American soldiers dealing with IEDs in Iraq. They made mention the military is rushing thousands of jamming devices for installation on vehicles.

I heard that too awhile ago, I forget the source.....Why they have to announce their plans in advance will always be a mystery to me.·
If someone in the military had a brain, you would think they would come up with a method of a) detecting phones along the road and b) detecting phones that are calling phones along the road, and not tell the·whole world of their plans before doing it.
Its not like they don't have the money to hire some smart telcom techs to put something together....
I had a comment in the post I took out later, basically it expressed shock in a very snide manner that it took more than 1250 soldier deaths by IEDs before the military responded.
I remember there was a story enemy combatants purchasing old Russian jamming devices. Apparently they worked quite good but only had a distance of a few hundred feet.
Their intended jamming target was incoming missiles and of course, at a few hundred feet away... you still get points for being close in horeshoes!!

Say your on a bus and the bus gets in an accident. You had a jammer running to stop from having to listen to ppl talk about nothing (Seinfeld!). You're knocked unconscious and for 200ft around you, nobody can use their cells to call for help (I don't know the actual coverage). I'd hate to see what happens to the guy with the jammer if someone dies from lack of emergency services.
Put a momentary power switch for the jammer·(one with·decent spring pressure) so if anything happens and you drop it, it turns off. I mean, if you want to kill everyones cell phone, putting a little work into it isnt too much to ask. Plus it would be more fun to kill the phones, turn them back on and have everyone start talking again, kill them again, repeat endlessly... Do this enough times they will quit using the phones entirely and you wouldnt even need a jammer.
Not that I promote using these things in public But it would be an interesting project tho.
OR put a deadmans switch on it (only stays on while being held)....
Nevertheless it is still illegal....perhaps a blowhorn to their face might get them to hang up!

Have you heard of the ultrasonic speakers? They project ultrasonic frequencies, but when they hit an object the patterns interfere to create frequencies in the audible range, making it appear as though the sound was eminating from the object. You could use one of these and surreptitiously point them at the person on the cellphone, to them it would appear that the sound was coming from themselves, you of course would be transmitting some really embarassing comment in an effort to shame them into hanging up, also other people arround them would hear the message and percieve it coming from them. Its not illegal, and would probably be effective if you can hide the transmitter from thier view enough, or point it at the ceiling and the entire bus would hear the comment as if god were speaking from the roof of the bus.

"Inside each and every one of us is our one, true authentic swing. Something we was born with. Something that's ours and ours alone. Something that can't be learned... something that's got to be remembered."
Different names, same (expletive)...
They're usually called 'mobile phones' in Europe, and 'Cell phones' in America.
Mobile because the first models were car-mounted, and well... mobile...
'Cell' is from the cellular structure of the networks.
in august 2001 (and for several preceding years) there was a single carphone in a leather carrying case that was 12" long.... the next year, august 2002, there were 8 cellphones for 12 people charging on the kitchen table.
i'm sure different areas may have experienced the cellular revelution differently, but thats how it happened in louisiana

"Inside each and every one of us is our one, true authentic swing. Something we was born with. Something that's ours and ours alone. Something that can't be learned... something that's got to be remembered."
But it also has an extendable antenna, something which is no longer built into phones.
