The internet back bone is Sat. based.
Wire/Fiber is expensive to install and maintain. We have a Fiber net in the USA that is replacing the old coax net but Arthur C. Clarks idea of bouncing radio off of a satellite is still the fastest extreme bandwidth communication we have.
Hughes Aerospace designed an emitter that can transmit and receive 125+ channels and a satellite can hold hundreds of emitters. That is the reason we have Direct TV( Hughes Aerospace), Sirius and the like. one satellite can handle many different types of traffic. One satellite equals hundreds of OC3 lines- OC3 service is a super high speed service with 155 megabits per second (compare with a T1 at 1.5 megabits per second, or T3 at 45 megabits per second). OC3 is equivalent to 100 T1s or three T3s.
So the satellite is an old but still way ahead of what wire line can offer. | |

If the internet "backbone" was over satellite, you'd never get better than 800ms on a long haul ping. | |

| said by keyboard5684  :The internet backbone, most of it, has very little to do with sattelites anymore. Most of it is fiber, ever under ocean fiber cables. Your speeds you talk about and services that actually benefit from sattelite is one way. That is because the delay it takes to get to you really does not matter much because it is a steady data stream, like a TV broadcast. Fiber is limited only by electronics so your OC-48 (2.488Gbps) or higher far beats your Sat speeds with about 300 times less latency. No, the cool thing about the internet is it was built to have multi routes it is Sat. and Fiber based. Right now all of the long distance companies are hiding the fiber routes and working on their sat contracts. It makes since to route fiber to Europe, Japan, and Asia but the cost per mile is still in line with having a bird in the sky. Also, when the internet went into the public domain it was kicked off of the sat net that the new internet that the research universities and companies are working on. They have both dark fiber and dark sat. channel routes to connect the world to it.
Right now there is a back log of birds to go up because of NASA, EAS problems with payload delivery. So right now fiber is holding its own.
The public at one time could see on the web the fiber routes and pictures of the IXC CO but because of concerns of terror attacks MCI, AT&T, Global Crossings and others are working to get more birds in the sky in addition to the fiber and coax. | |

| Re: Who needs those classic things Those are comm links in the event of a catastrophic failure. Those are not used to route data or voice at the moment and won't be unless they are absolute last choice.
You have been watching to much tv. Data and voice over satellite is very expensive. And there is not data routed over a satellite link for any backbone needs at all. No one is stupid enough to do that.
Nasa does not launch the satellites I'd hate to tell you that. A separate company does. And they ship the satellites out to the equator to launch them from a boat or even from places in Europe and china. Nasa releases government only satellites.
As of this writing you can still view their fiber hops that are lit. Even level3 lets you view them.

| Ahhh who ever has you believing that really has you fooled and fooled well.
First off bouncing waves off a satellite takes a long time compared to fiber. And has finite bandwidth because of both the atmosphere and the amount of frequencies that can be used without interfering with other equipment.
One satellite is not equivalent to hundreds of oc lines. Read a bit more at what an optical carrier line is capable of. 12.5 gig a second in the real world. If any satellite could send 100 times that down the pipe without nuking the people in it's foot print we would be able to have crap loads of bandwidth for little to no cost via a satellite.
OC are not equivalent to any t1 or t3's , they are different uses entirely. An oc is a carrier class optical line. It carries anything raw. A t1 does not have that ability.
Satellites are relatively new compared to your "wire line" concept since copper is in that base. And so is fiber, a satellite link can not beat out a fiber link. Go back and do a bit more reading about the differences between links.

So the satellite is an old but still way ahead of what wire line can offer. You must be kidding me. Sat's are one of the slowest forms of communication we have. Not the fastest. Averaging about 500ms latency and disruptions in bad weather. And the fastest bandwidth we have is fiber for your information. DWDM can handle over 400GBps according to the fiber optic faq. » Fiber Optic Forum FAQ » What is Dense Wavelength Division Multiplexing (DWDM)? And saying its way ahead of what wire can offer is just ridiculous Those are lab speeds not real world efforts YET. But it's coming.... Man oh man the new technology is coming. Wonder when Verizon will use this on the poles

| For the nth time, cell phones don't use satellites. The energy required to propagate a signal that far and still have it be meaningful at the other end would drain the battery on a modern phone in about 30 minutes, I'd guess. Traditional cellular networks use big towers standing on the ground to provide coverage, with building-mounted panels in more urban areas to supplement that.
There are satellite phones, but they're larger, bulkier, and ridiculously expensive (pay per minute, usually something like $2 per minute). That's where those airphones you find on planes get their service, IIRC.

| Re: Quick call tech support... Iridium's network works sort of like a cell phone. The cells are formed by spotbeams and are 30 miles in diameter. Most of the other satellite phone networks use stationary satellites. You point a panel antenna at the direction of it and select the band/frequency for the satellite you want.

| SWAG Well, it's probably another case of "whiskers" shorting out the power.
Various metal components grow "whiskers" in space--when these become long enough, they short between circuits.
The solution is easy, and was long used: just add a tad of lead in the alloy.
Problem is, the rabid enviros banned lead--even in tiny amounts where it is desperately needed. So we get whiskers.
Reminds me of the foam insulation on the space shuttle external fuel tank. Didn't have a problem with it falling off and damaging the orbiter until it was re-formulated for environmental reasons. I guess some folks think it's better to reduce those volatiles released into the atmosphere than to keep astronauts alive....
(It's not that I'm anti-environment. It's that both of these possible pollution sources pale in comparison with the wildly toxic by-products of any space launch. I'm sure that both the foam and the total absence of lead in satellites does about as much good as using water-based paint instead of oil-based paint to mark nuclear waste containers....)

And Geo Comsats don't fall back to Earth. They use the last of their fuel to boost themselves out to a graveyard orbit.
