The race for Internet service from space is on, again.

After a series of failed satellite Internet projects over the past two decades, fresh investment is coming into the sector, and at least three high-profile projects are moving forward.

OneWeb, a London-based consortium backed by tycoon Richard Branson, announced in June it had raised $500 million from investors including Airbus, Qualcomm and Intelsat to advance its plan for satellite broadband to underserved parts of the world.

Also this year, US-based space exploration firm SpaceX secured a $1 billion investment that could help founder Elon Musk's plan to build a satellite Internet network, with backing from Google and the financial firm Fidelity.

US-based LeoSat, backed by Europe's Thales Alenia Space, is also working on a satellite broadband project aimed at business. And Samsung outlined plans in a research report this year "to make affordable Internet services available to everyone in the world via low-cost micro-satellites."

The projects seek to launch hundreds of low-orbit satellites to beam the Internet from space. The initial costs could be high, but would avoid the expense of building ground-based systems for wired or .

If the plans sounds familiar, we've seen this before.

Teledesic, a 1990s project backed by Microsoft's Bill Gates and Saudi royal family investors, died before it went into service, as did another venture called SkyBridge, whose assets were eventually acquired by OneWeb.

Greg Wyler, chief executive of OneWeb, said much has changed since Teledesic abandoned its "Internet in the sky" plan more than a decade ago: the cost of satellite technology has come down, and most people now realize that connectivity is needed to spur economic development.

"If your goal is to end extreme poverty, boost the things that contribute to economic growth like health care and education, all of those things sit on a foundation of connectivity," Wyler told AFP.

OneWeb plans to begin launching its 648 low-orbit satellites in 2017, and begin connecting customers by 2019, Wyler said.

The company has "contractual arrangements" to operate in more than 50 markets and is looking at a broad global footprint.

"More than half the world is not connected," he said.

In some developed markets like the United States, individuals who live in remote areas could subscribe to Internet broadband. In developing countries, it may be schools, centers and other government entities.

"Our technology fundamentally reduces the cost of connectivity," he said.

Musk vs Branson

An equally ambitious plan is being developed by Musk and SpaceX, which could launch as many as 4,000 satellites.

Musk said on Twitter that he sees "advanced micro-satellites operating in large formations" that would provide "unfettered (Internet access) certainly and at very low cost."

Details of the SpaceX plan are still sketchy, but the company filed plans with the US Federal Communications Commission to begin testing. Eventually, FCC approval could allow the SpaceX project to offer broadband services globally.

LeoSat's plan calls for between 78 and 108 satellites for a broadband network aimed at high-volume business customers such as major corporations, governments, maritime operators and the oil and gas industry, said chief executive Mark Rigolle.

While LeoSat, a startup created in 2013, is aiming at only a few thousand customers, it can also serve as a "backbone" for other operators, which would mean millions could use its connections.

"We want to become 'fiber from the sky' from anywhere to anywhere," Rigolle told AFP.

"It's not a product that is available in today's market."

The company was created by former oil and gas industry executives who understood the need for better connections in remote parts of the world, Rigolle said.

These low-earth orbit systems require more satellites but can cover areas not served by the higher-orbit systems, with better connectivity because of faster transmission speeds.

Rigolle said LeoSat will be able to transmit around the globe "from satellite to satellite without ever touching the ground," create a system which is "effectively faster than fiber" and more secure.

Natural advantages

Scott Pace, director of the Space Policy Institute at George Washington University, said now may be an opportune time to launch a space broadband service because of advances in technology and growing needs for connectivity.

"Space has a lot of natural advantages" over terrestrial systems, he said.

"Space systems provide a way to cover massive amounts of territory very quickly, and the new satellites are increasingly sophisticated."

Because growing numbers of people around the world rely on wireless broadband, Pace said that "demand is more intense than in the 1990s and satellite systems have a chance of meeting that demand and being a player."

Still, he said it's not clear if satellite systems can compete effectively with ground-based systems. And he said that any new entrant will still have to compete for airwave spectrum and deal with regulators in various countries.

With a number of firms competing, it is not clear if all will survive, Pace said.

"It's a question of who can get there quick enough and surmount the regulatory hurdles," he said.

"I don't know that there is room for multiple systems. there might be room for one, maybe two."

I live for the day.
One Caveat. I hope that they are going to incorporate end-of-life de-orbiting of these satellites.

It will be great if you need broadband on your yacht in the middle of an ocean, or in a rural somewhat undeveloped area. For the rest, its just another internet provider with all the attendant billing.

If you live in the middle of nowhere, great.

For the rest of us, Cable will always be better, because you can have theoretically infinite bandwidth on Cable, which is to say just add more lines with any number of lines using any number of frequencies. Satellite is limited.

Therefore wireless will always be inferior.

"Faster than fiber..." is impossible unless the laws of physics are repealed.

The speed of light from earth to geostationary orbit and back is a delay. This delay is (23000mi + 23000mi)/186000mi/sec. = 0.247 seconds added to the time of signal travel on the ground. Satellites in synchronous orbit must be on the equator, and 3 is the least count that can see over the horizon. Distance between satellites will be an additional (2 * sqrt(3) * 23000mi) = 79,672mi., 0.428 seconds. Add both = 0.675 sec one way, 1.351sec round trip.

Internet uses Transmission control protocol (TCP) which sends an acknowledgement (ack) for each good packet received and a neg-ack (nak) for corrupt ones. An ack for several good pkts in a row (count of good before ack is sent is called a "window"). The usual window (7 pkts) closes transmission at the sender until the ack is received. Data rate is throttled to very slow by long transmission times.

Fiber delay is much less so throughput is more.

LEO satellites will have higher throughput, but will need exceptionally good switching and linking technology. The more satellites in LEO, the more complicated the possible routes are through these satellites. Each such LEO Sat is also a router. These flying routers are constantly changing position relative to the earth and to each other. The spectrum these Sats use must also be very carefully arranged so that no Sat steps on another Sat's transmission. Receivers must know what to listen to and what to ignore. All very complex. TCP acks and nacs will complicate matters even more. Maintaining a routing table for each satellite that changes dramatically every few minutes may cause more traffic than customer traffic.

Not using TCP (both cases) means user defined protocol (UDP) which will be proprietary. Data trans errors will increase. Skype will only work on LEO, GEO Sats will have delays that are unacceptable.

Whatever happened to the idea of near space communications platforms like the Dark Sky station? Low latency, some maneuverability, ability to be brought down for upgrades and re-launched - without expensive rockets.
