Facebook, Ka-band and Africa

Tuesday, October 13th, 2015

Using state of the art satellite technology, Eutelsat and Facebook will each deploy Internet services designed to relieve pent-up demand for connectivity from the many users in Africa beyond range of fixed and mobile terrestrial networks. Satellite networks are well suited to economically connecting people in low to medium density population areas and the high throughput satellite architecture of AMOS-6 is expected to contribute to additional gains in cost efficiency.

That quote is not from a press release issued in 1999. It’s from Eutelsat’s announcement of a partnership with Facebook on 5 October 2015, leasing Ka-band capacity on Spacecom’s forthcoming spacecraft. In 1999, satellite was seen as the “leapfrog” technology, intended to bypass old wireline or tower-based schemes to get the Internet out to the people of Africa. Although “good for data” Ka-band payloads were not widely available back then, the same disadvantages are still lingering:

  1. the high cost of space segment
  2. customer premises equipment is not cheap
  3. latency will always be an issue

Unless Facebook dollars subsidize the first two costs, we’ll only need to deal with physics.

The RF signal to and from the geosynchronous spacecraft will always require a 1/4-second to complete, then add a little bit of time to get the content, then another 1/4-second to serve it up. We’re not getting into video or any rich media — just the basics. Fine. People without any connection will be happy with whatever they get. High-throughput or not, you get what’s allocated to you.

Let’s consider reliability. First, there’s the issue of a reliable electric supply. Do we have enough of that in Sub-Saharan Africa? Next, there’s the signal itself. Even with a good link budget, and backing-off on the data rate a bit, you’re dealing with a considerable amount of rainy conditions for wider areas, so you can expect the signal to fade or experience complete outages during the rainy season.

Considering satcom’s promise hasn’t been kept for so many years, true “leapfrogging” is happening everywhere. In Rwanda, for example, 4G LTE is being built out and it kills any comparison to satcom alternatives using geo satellites. Using LEOs from O3b Networks works well, but somebody stills has to make the economics work.

So good luck to to Facebook and their internet.org effort.

Sabrett’s Satellite

Friday, March 27th, 2015

This week’s news that traces of nitrates were found by SAM on Mars — and the Fark headline linking it to hot dogs — reminded me to ponder the one decent rumor to come out of the Satellite Show in Washington last week: Apple is buying a spacecraft from Boeing.

You might as well sell one to Sabrett’s to connect all their hot dog carts around the world. Hey, they’re selling branded merchandise, so why not?

Google, Facebook or Amazon might buy one, too. Does anybody at Reuters check this stuff? One call to anybody in the business would tell you “you’re way off on this one.” This is link bait.

Designing, building, launching and operating a spacecraft takes a long time and costs a lot of money. Understand this. This cannot change.

You can have all the bandwidth and high-throughput possible on the spacecraft’s payload, but it means absolutely nothing if you can’t make use of it on the ground. One-to-many distribution is where this technology makes sense — not point-to-point or multipoint-to-multipoint. That’s why TV loves satellite. This network topology can’t change much. Higher frequencies need better antennae for reception — and transmit has its own challenges. If you plan on using mobile frequencies such as those used by Thuraya in Asia and the Middle East, you’d be planning on coordinating with terrestrial and mobile telecoms for more years than it would take to build the spacecraft.

Get over it, people. Building a new satcom network isn’t worth it. It’s like selling hot dogs on Mars: who are you going to sell it to?

With O3b Networks actually operating and building out globally, get in that space and figure out how you can work with it. Latency is minimized on the tech side, and terrestrial connectivity is being added for “the other 3 billion people” inhabiting this planet who are without Internet access.

And put some mustard on it.


O3b Launch — “пуск!”

Happy people at O3b Networks, watching their payload launch into space yesterday.


Happy Antennas for O3b

Wednesday, August 8th, 2012

Here’s a time-lapse video of three new antennas being installed at the Sunset Beach East Station in Hawaii. They’re likely tracking antennas, as the O3b spacecraft will be LEOs.

Dig the “happy antenna dance” at the end.

More Money for O3b

More interesting news for O3b Network: $1.2 billion in funding. As reported by the WSJ

 Satellite communications company O3b Networks said Monday it has raised $1.2 billion from a group of investors and banks, its final funding round before the launch of its global satellite broadband network.

O3b, which is backed by Google Inc., plans to launch its fiber-quality Internet service serving emerging markets in the first half of 2013, after securing $770 million of debt financing and $410 million of equity investment.

The firm’s name refers to the “other 3 billion” people in the world currently without access to broadband Internet.

“We are looking to connect the unconnected, now we can start to do that,” Chief Executive Mark Rigolle said in an interview.

The company already has around 10 customers for its service, who have signed deals valued at $500 million to $600 million to use its infrastructure, Mr. Rigolle said.

O3b is selling capacity on its network on a wholesale basis to Internet service providers and telecom companies. Mr. Rigolle said he expects the strongest long-term demand to come from mobile phone companies in emerging markets, which lack the fiber-optic infrastructure to offer their subscribers high-speed Internet access. O3b’s network will be able to offer “backhaul” connections in place of a fiber network.

Chicken & egg contingencies aside, this is a positive step for O3b. Or is it?

Yes, they’re fully funded for design, build and launch, but will it work well enough to really get some cash coming in? We’ll have to wait another two years to see whether that question will be answered. In real “Internet time,” two years is a very long time and things could change materially — especially in high-risk space-based ventures.

Curiously, this venture is still referred to as “backed by Google,” while SES will increase its ownership to 34%. And they only have to contribute US$75 over the next two years. Judging by the composition of its board of directors, SES seems to be in control here.

Considering the utter lack of connectivity in the regions where “the other 3 billion” people are situated, this is still a good idea. 100-millisecond latency is good enough. Add the possibility of micro-payments via mobile Internet, this could prove to be a real winner. Now hurry up and launch the spacecraft!
