Satellites Providing Internet To the 'Under-Connected'
Taco Cowboy writes "Today, a Russian Soyuz rocket shot the first 4 of 12 satellites in a new constellation that are designed to provide affordable, high-speed Internet to people in nearly 180 'under-connected' countries. The orbiters, part of a project dubbed O3b for the 'other 3 billion' people with restricted Internet access, were built by the Franco-Italian company Thales Alenia Space. They will orbit at 8,062 km and will weigh only 650 kilogrammes (1,400 pounds) each. 'There are already geostationary satellites providing this type of services, but at a prohibitive cost for many end-users. Existing satellites generally obit at an altitude of some 36,000 kilometres (22,000 miles) above Earth, weigh in at a hefty four to six tonnes each, and take much longer to bounce a signal back to Earth—about 500 milliseconds to be exact, according to an O3b document.
"It is such a long delay that people speaking over a satellite link will shorten conversations, interactive web has an extremely poor experience and many web-based software programmes just won't function." Crucially, they will communicate with Earth four times faster, said the company, and six would be enough to assure permanent coverage. "O3b's prices will be 30 — 50 percent less than traditional satellite services," said the document. ... Launch company Arianespace, which will put the satellites in orbit, said the O3b constellation will combine "the global reach of satellite coverage with the speed of a fiber-optic network." ... The next four satellites will be launched within weeks, according to Arianespace, and a final four "backup" orbiters early next year.'"

Have gnu, will travel.
I was wondering when bandwidth would be available to those of us that live south of downtown.

The private investors are just the public face of this venture.
Their accounts receivables are insured against loss by the French government. This is a way for the French government to partially subsidize its own aerospace industry (in this case, the satellites are made by a French and an Italian joint effort), and at the same it's a way to control which war lords/governments in Congo, Ivory Coast, Mali, or Syria get free satellite internet access, and which war lords/governments in those parts of the world do not.
In other words, this infrastructure is a way to buy yourself some influence in those parts of the world (where French influence has been slowly shrinking otherwise).
Geostationary sats are exactly what they're trying to avoid.

In theory round trip latency should be 53ms. ( (8062km *1000) / 299792.458 = 26.8ms one way). That is almost a factor of 10 better than current satellite offerings. It may even make games playable.
Silence is a state of mime.
I actually RTFA and couldn't find a list of the "180 under connected countries" but as a satellite internet customer for several years the US should be on the list.
My Stats: ~900 ms latancy, 1.5 MBit, daily cap of 300 MB download, all for 3x the price of the lowest cable or DSL plan not available in my area.
It's amazing how all the telecom companies talk about providing great service until you live a mile and a half down a dead end road they have no plan to ever run lines down (Cable), or you are too far from the nearest DSLAM for DSL.
Why would you use lasers when you have microwaves?
