SpaceX Says Satellite Broadband Is the Future, But It's Actually Already Here

If everything goes according to program this morning, then Space Exploration Technologies Corp. (SpaceX) will have launched a pair of experimental internet satellites into orbit past the time you lot read this. Slated to launch onboard a rocket from Space Launch Complex 4 East (SLC-4E) at Vandenberg Air Force Base in California, the two satellites are intended to exam the feasibility of using a space-based cyberspace service that can provide high-speed, depression-latency data communications worldwide. According to the Federal Communications Commission (FCC) filings that SpaceX used to get its license to operate those satellites, the ii satellites exist operational for at least six months, and volition be used for a few minutes per solar day as they pass over the SpaceX office in the Seattle area.

SpaceX is ane of one-half a dozen companies that have practical to the FCC to operate satellites that'll provide this broadband access. These satellite networks are in varying stages of development, but if they're successful, they should provide substantially ubiquitous, high-speed broadband to consumers and businesses anywhere. If they're too practical, and then they should dramatically ease the brunt of networking businesses with multiple employees at many different locations.

Not And then Far In the Future

But you'll notice that I used the give-and-take "if" a few times. This is because information technology takes a lot more than than a couple of examination satellites to be successful in this detail game. And information technology also needs to be practicable, pregnant that the costs and complexities need to be rational enough to make sense to the IT folks who have to manage it and to the Chief Fiscal Officer (CFO) who has to pay for it.

To make things more interesting, satellite internet access isn't new. In fact, information technology's been effectually long enough that I first tested information technology over 20 years ago past using a service called DirecPC, which was provided past Hughes Network Systems LLC. While satellite net in those days provided an important culling for companies that needed to communicate with remote offices, information technology wasn't as useful every bit these new networks will be.

That's because satellite-based networking in those days had a major drawback: latency. The satellites back so were in a geostationary orbit, meaning they were located approximately 22,236 miles above the earth. That'due south not simply a big hop; it also meant that a information packet would take nigh one 2d to make the round trip betwixt a computer at 1 cease and a server at the other. A full second is basically forever in the universe of high-speed networking, and that hasn't gotten any less important as business organization applications have evolved with the internet in mind. If anything, low-latency functioning is more important than e'er, even to businesses using only standard concern apps, only certainly to whatever using technologies such every bit streaming, such as video conferencing or fifty-fifty loftier-speed information analytics.

What'south Really New

What's changed from those days is that SpaceX and a number of other companies are planning to place satellites in orbits much closer to the globe. That means the latency is going to exist much lower because the delay from cease to end is just a few milliseconds—much closer to what you're used to when dealing with the internet using today'south commercial broadband networks.

But because those satellites will be much closer to the earth, they tin can't also appear to remain stationary in the heaven. They're going to exist moving at a pretty good clip and that can take its own detrimental effects. To solve for that, there needs to be a lot more satellites so that they remain in view of the ground at all times. Worse, those satellites need to be fairly close to the ground and then that users there don't need powerful radios to achieve them. The way to fix that is to add fifty-fifty more satellites so that they're always shut plenty.

No surprise then that SpaceX is proposing to orbit something like 12,000 small satellites to build out their satellite network. Equally y'all might imagine, information technology'll have a while to get all of those satellites into their respective orbits and figure out a reliable manner to manage them. The other competing services have plans of varying complexity only they all have ane affair in common too low latency. That one thing in common is that they're all still plans, not existing services. Given the number of satellites it'll accept to move from the plan to the service stage, they're probable to remain that way for a while.

Only before you dismiss the concept, let'southward point out that satellite internet access with gigabit speeds and low latency already exists and its in apply globally. What'due south more than, you may accept used it. If you've ever used Wi-Fi on an airliner, peculiarly ane traveling internationally, or made a FaceTime call from a cruise transport, then you've used a satellite connectedness, and it was probably provided by Luxembourg-based satellite network provider SES.

SES uses a constellation of 12 satellites, with 8 more than being launched in 2022, orbiting at nearly 5,000 miles above the surface of the earth. This is close enough to continue latency down to 120 milliseconds while orbiting the earth virtually three times per twenty-four hours. The low latency and loftier bandwidth—up to one gigabit per second—make the SES satellites a good solution for cloud operations.

Co-ordinate to Sergy Mummert, Senior Vice President of Deject Services at SES, satellite network access is at present both bachelor and practicable. This ways that its bear upon on the data eye is minimal, and getting a adept, usable connection can be done at a reasonable cost. "People aren't waiting for a cobweb connection," Mummert said. He pointed out that information technology'due south not uncommon for a adept cobweb connectedness to take months to be put in identify.

In fact, depending on where your operations are located, a fiber connectedness may not be available for years, if information technology's ever bachelor. Fifty-fifty if your operations aren't in the air or at ocean, they can still be in areas with poor network admission and satellite networking is always there. And even when cobweb is bachelor, a satellite connection can still brand sense, both equally a backup for the solar day when a backhoe takes out the fiber or simply every bit extra capacity that'south available when y'all demand information technology.

And so, while SpaceX and the others may eventually provide admission to a ubiquitous, low-latency, and fast cyberspace connexion, you don't need to await if that's your only solution, though your options today are somewhat limited. But if and when those options expand with SpaceX and its competitors, then you just might find an answer to your fiber provider headaches upwards in the heaven.
