Not thousands of satellites, you just need bigger pipes. You could technically have a few satellites in geosync orbit, but the antenna on your cell phone and power needed for such communication would be big. Enjoy your 3 minutes talk/10min idle cell phone talk time.

But hey what do I know I'm a kirby~! That's now looking up old Oscillators for nefarious purposes.

Then you run into major power issues. Bandwidth isn't free. I'm sure there is a solution (like an improved spread spectrum), why don't you get a PHD in EE and invent it?

Prolly may become an EE, it's the only field of science that interests me. Radio stuff and the manipulation of radio waves imo is such an exciting science. Really, look at your cell phone; and be fucking amazed how it communicates on a spectrum of frequiences that carry your voice/data/message/communication/packets over the fucking world.

The way it used to be in the 1900's, 1950's is long gone. It's fucking 2010 and one person can communicate with the whole world in a matter of fucking seconds.

nah, a cell to cell phone call half way around the world spends probably less than a mile total going over cell towers.

I was including from your mobile station (cell phone) to tower, to central office, where it's routed off to the co/tower of the destination phone to then the person you wish to speak.

well those other OTA xmissions can use big antennas so that's cheating.

Cell phones to towers are also OTA...

A GPS receiver only calculates the difference in tone and time between 3 or more satellites. The GPS satellites only kick out tone. Nothing else.

You do realize that GPS is just a fucking tone, right?

Nobody uses pulse dialing anyways. Its all tone.

Well, just "tone" apart from the 2 different carrier frequencies, a pair of PN spreading sequences modulated onto the carriers in quadrature, and the downlink data the contains almanac, timing and supervisory data.

APart from that, it's just "tone".

Can't believe nobody got the correct answer to the question. Nothing to do really with bandwidth at all.

What kind of answer are you looking for?

The biggest issue is money/performance.

Money being the biggest motivator, outside military almost nothing.

As for performance, location on earth to the satelites location in space wouldbe the biggest issue; Between low orbit and geostationary. And of course inb4 congestion due to few voice channels.
