How I would like to change the cell phone industry [was AM electromagnetic waves: 20 KHz modulation frequency on an astronomically-low carrier frequency]

I are an radio/RF/wireless/communications/whatever engineer and I
agree with John Navas that cellular is nowhere near 3GHz.

That should have been about 30%, but in any case, I am an engineer
and there isn't a whole hell of a lot of anything different between
1.9 GHz and 3 GHz.

Zoom in to the area between 1.9GHz and 3.0GHz. There's a huge amount
of point to point, wi-fi, WiMax, satellite, XM/Serius, radar,
military, etc, stuff in that area. That's also where Sprint and
others have recently purchased bandwidth for advanced data services.

What? Some trivial differences in path losses? Antennas a bit different
in size by what, 4 mm unless I slipped a decimal point in my head?

There's no disgrace in admiting that you've made a misake. There's
plenty in trying to bluster your way out of admitting it followed by
trying to trivialize your mistake.

I agree there is a lot of stuff allocated between 1.9 GHz and 3 GHz,
but FCC regulations wasn't the point.

Lemme try again.

Put up two transmitters with everything identical in terms of lambda,
one on 1.9 GHz, one on 3 GHz.

Run around all you want with a field strength meter.

There isn't going to be spit worth of difference.

Antenna sizes? A matter of millimeters.

Equipment construction techniques, part availability, etc? Negligable
differences.

There isn't much difference between 2 GHz radio and 3 GHz radio.

Do the above with 800 MHz and 3 GHz. Now you start seeing some
differences.

- S N I P -

RADIUM,

The please keep 'your' OT crap! OFF of Rec.Radio.Shortwave
* The Theard Goes Where The Thread Goes
* That Is The Nature Of NewsGroups

- I had to start a new thread because some
- jerks decided to post irrelevant nonsense.

Relevance in in the Mind of the Poster.

Right now since the 'topic' is CellPhones - I makes me wonder
what kind of Cellphone and Service Provider others here may
have . . .

OK starting with me :
I have a Motorla RAZR V3 via AT&T {Cingular} Wireless
and I do not want any changes to the Cellphone
Broadcasting System [.]

Keep Posting Your Scientific and Cellphone BS to
Rec.Radio.Shortwave and you will see replying to
it with what ever comes into my mind and inviting
others hear to do the same.

However, leave Rec.Radio.Shortwave "Off" your
Cross-Posting List and you won't have to deal
with me. Now woldn't that be nice.

Say Cuhulin do you have a CellPhone ?

David I know you must have a Cellphone.

Bet-Ya Telamon has a Cellphone.

Wondering -if- DX Ace has a Cellphone ?

Burr way over in the PI - you got a Cellphone over there ?

Hey Back At You "Radium" Wondering . . .
You Gotta Cellphone and who is your Service Provider ?

IF YOU GOT A CELLPHONE LET RADIUM HEAR ABOUT IT !

I B 'rhf' Listening to my Shortwave Radio
with my Cellphone near-by bye bye ~ RHF
