Teledesic Comes Down to Earth
hibachi writes "Teledesic, the ambitious plan to build a constellation of low-earth orbiting satellites for global broadband services, has died on the assembly room floor. According to this press release, "the company does not believe that it is prudent, purely on speculation, to continue the substantial capital expenditures required to construct and launch the satellites consistent with the timing required to meet FCC and ITU regulatory milestones." Brainchild of Bill Gates and Craig McCaw, Teledesic held the promise of globally ubiquitous high speed Internet. It seems Teledesic's plans grew less ambitious over the years until finally the painful lessons of Iridium, and the current telecom climate, drove the last nails in its coffin. I am sad to see this happen."
Gives a whole new meaning to "never got off the ground".
...someone DID imagine a Beowulf cluster of them.
If they're going cheap, they might make a pretty impressive IEEE 802.11 antenna.
I think that a big part of their problems comes from trying to provide internet acess to 3 billion people who previously didn't have it (is it that few?). Not that this goal isn't admirable, but I think it would be better to concentrate on getting consistant electricity, clean water, and high quality food to the world poor, instead of internet access (lack of computers/electricity to run them could also be a problem).
Galium Arsenide is the material of the future, and always will be.
Unfortunatly we see this kind of thing happening everywhere. Telecom companies devaluating their recent investments for UMTS licenses, Companies like Worldcom and KPN QWEST in serieus trouble (right to the point that at least KPN QWEST goes bankrupt). It is no surprise that Teledesic does not want to venture into a territory which is hostile to say the least at this moment. To uphold their promise they must not only build, launch and exploit the satelites but they must also create the groundstations and maintain them for the governments and regional governments. Otherwise those satelites would be very expensive space junk.
So they are looking at a very substantial investment in a time where no-one would invest because of unstable markets.
Unfortunatly there is no forseeable uplift for the telecom sector. It's a wise decision to stop now and to evaluate the situation. Perhaps when the worldeconomy is seeing some uplift the company can start again with its original plans. Until then i'm afraid those 3 billion people will still not have access. Although they will never miss it by the way, nor am i afraid that they are worse off then those who do have access.
...to have something better than ISDN in my house here in Japan. At least its better than dialup where I paid $300 a month.
Apparently, this country needs to learn what does "national coverage" mean, and that linking two islands with 45mbit link and selling it to 35000 dsl, isdn, and dialup customers is not exactly the correct way of doing things.
Oh, and no signs of current-gen satellite internet in Japan either. DirectPC Japan sells "only to enterprises" with $2000-some for setup and after that billed PER MEGABYTE downloaded.
Does anyone know what the bandwith would have been? I dread to ask about ping...
The Helios project will provide the same functionality, but with cheaper maintenance and launch costs. It is a solar-cell powered flying wing that will soar at about 60000 feet or so, with 200 pounds of payload. It may very well be the specific reason they pulled the plug on Teledisc, since they realize that most satelites will be obsoleted too soon for them to proceed with the project.
Stop the brainwash
Iridium bugs me. I've seen a lot of people claim it failed because of the technology. But this just isn't the case! It *might* have failed based on the technical [de]merits, but it never made it that far.
I know this because I tried to buy an Iridium phone. I spent months and months trying. I tell you they WOULD NOT SELL ME ONE. It was a joke! No resellers had them, and there was no plan. The best I ever did was find a fly-by-night in Taiwan who would sell me a phone, but not a service plan. Who would buy a phone with no service plan?
It was frustrating too, reading their glossy pamphlets and their web sites. They actually gave you (the customer) examples of what type of people would use an Iridium phone. Topping the list was Saudi Oil Sheiks! I'm not kidding! I tried to tell them, im not an oil sheik, but I HAVE MONEY and I want to BUY.
Iridium failed because of internal failures inside the company (and motorola). They got caught up in internal politics and self-absorbsion. Apparently they forget to do marketing and build distribution channels.
Here in the UK it was perfectly possible to buy an Iridium phone. Almost every electronics shop on Tottenham Court Road stocked them. I even once saw someone buy one.
The problem Iridium had was deeped. When the economics were first calculated in the mid-1980s, nobody envisaged a ubiquitious cell phone service and global roaming. (Nor did they imagine that cell phone services would price their minutes at $0.20 or less.) The key demographic of Iridium users - i.e. travelling businessmen - already had cell phones, and weren't prepared to swap them for larger devices, with lower quality sound, and which cost 30x as much per minute.

Being a "victim" of the telecom crash myself, I feel like speaking freely about the not so positive parts here...
In the last 5-10 years, there's been a constant push to develop more and newer technology to sell to willing customers (in the highly developed parts of the planet). This was in blind disregard of then common sense that enough is enough, if you don't need more features you're not going to buy it.
Meanwhile, the amount of technology standards and "blueprints" for communication systems is advanced enough to last quite a while without new developments. Some refinement is good, but wider implementation of this technology would do much more good in the world, for peace and equality (thereby reducing risks of conflict between nations and peoples!). If every moderately developed country would have basic internet and telephony services available for 80-90% of the people for reasonable prices. The world would be much better off than with another way to get broadband for a few above average rich people.
Of course, the need for food, shelter, education and freedom rises far above the need for communication and internet facilities. Also 3 million people a year are dying of aids, and so on and so forth... Life is not about more bandwidth (really!)

Ever see an Iridium Flare?
Satellite broadband for the masses won't work. Period.
Here's the math to back that up.
Assume a bird at LEO - about 100 miles up, serving about a 500 mile footprint.
Assume said bird is running a 1 GHz wide communications channel (not a 1 GHz center frequency, 1 GHz bandwidth. That puts the center freq around 10 GHz at least, where there are very large space losses - just getting your signal down costs you a lot of signal).
Assume the protocol used by the bird gets about 4 bits per second per Hz (That's a pretty high value - the signal to noise ratio will have to be VERY low for this to work.)
Assume an overhead of 2 bits per byte transmitted. This includes all protocol below TCP/IP, error correction, collisions, retransmits, etc.
OK, given those numbers, you get about 400 Mbytes/sec downlink throughput.
Assume you want to supply everyone with DSL equivelent speeds - 40 kByte/sec.
400 Mbyte/sec divided by 40 kByte/sec = 100 thousand users per bird.
100 thousand users per 500 * pi miles = 64 users/square mile. Anyplace the user density is higher than that would swamp the system.
And remember, I've been using very LARGE (i.e. very favorable to satellite downlink) numbers.
Satellite is GREAT for wide-open, low population density areas. The problem then becomes you cannot get enough people to pay for the birds.
In high density areas, land based wireless and wireline are MUCH more cost effective. In less populated areas, ideas like the solar aircraft are more feasible than satellites. In REALLY unpopulated areas, there just ISN'T a technology that can do the job without some sort of subsidy.

because what Teledesic could have offered has so much potential.
Apart from the fact that you save wiring up hundreds of countries that cannot afford it - and hence provide internet access to millions upon millions of people that previously could not get online - but what's more, for those of us road warriors, it could have been a godsend.
Yeah, it's all very well to have broadband internet - but it's only available at your desk! What happens if you're out in the field and you want to send/stream a movie back to base? At the moment, it's damn hard (and expensive) to do it... but allow for this to take off, everywhere you go, fast internet. Teledesic is to the internet what the mobile phone is to voice telephony.
I know there are still latency issues to work out, but eventually it could become like many households (especially students) where there are no landline phones, just mobiles - instead of having a fixed, wired access point, everybody has wireless, move anywhere mobile access... anywhere in the world.
I'm sure it'll happen, but minus the backing of the big guns like Gates et co, it may take a while longer.

This project was BillGatus's dream of having ubiquitous internet access for _windoze_users_only_ It was going to be a way to push Palladium off onto the rest of the world by being the only way to access the internet globally.
That the project died is a very great thing for Freedom. We should be happy because now Gates can't force people to use _his_ internet.
Do you seriously think that Gates would have allowed open source software to access his internet? Do you think we'd be able to access slashdot? Of course not.
To paraphrase Lyndon Johnson:
"I myself do not want to go to bed by the light of a Microsoft moon."
Evil is the money of root.
If the West aren't careful, India could end up owning worldwide broadband multimedia on demand.
Seastead this.
the specs probably changed considerably from when i was doing this, but at that time, they were considering a network of 840 satellites! in some areas of the world you had maybe 10 or 20 satellites visible at once. if this thing had ever got off the ground, you'd have had some pretty spectacular displays around dawn and dusk.
what an amazing waste of money. personally i think that high altitude balloons sound like an excellent idea as a cheap alternative to behemoths like teledesic.
