Teledesic Comes Down to Earth 176
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."

The groundbased technology will be cheaper and easier to install and upgrade, and it will have a lower latency, and it will have a far lower initial investment cost, laying the ground for more competition.
This means that the whole cost of the global satellite network will have to be covered by the customers who cannot obtain the ground based two-way communications; the people who live out of range from a >3K people population center. Not very many people. That in turn means the prices per in-the-woods-hermit-connection are going to be so prohibitively high that very few could afford it. Probably so high that you could pay for your own fibre connection for the yearly charges if you're living in a civilized country.

Satellite broadband for the masses won't work (Score:3, Interesting)
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.

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.

Is no one happy about this? (Score:3, Insightful)
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.

If the West aren't careful, India could end up owning worldwide broadband multimedia on demand.
i did some of the modelling for teledesic (Score:3, Interesting)
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.
