Starlink Will Hit 300Mbps and Expand To 'Most of Earth' This Year (arstechnica.com) 161

Posted by msmash from the up-next dept.
Starlink broadband speeds will double to 300Mbps "later this year," SpaceX CEO Elon Musk wrote on Twitter this week. SpaceX has been telling users to expect speeds of 50Mbps to 150Mbps since the beta began a few months ago. From a report: Musk also wrote that "latency will drop to ~20ms later this year." This is no surprise, as SpaceX promised latency of 20ms to 40ms during the beta and had said months ago that "we expect to achieve 16ms to 19ms by summer 2021." It sounds like the speed and latency improvements will roll out around the same time as when Starlink switches from beta to more widespread availability. Two weeks ago, Starlink opened preorders for service expected to be available in the second half of 2021, albeit with limited availability in each region. Reader xonen writes: Starlink has become available in my country, The Netherlands. I verified pricing -- it's the same prices in Euros as in the USA in dollars, which was to be expected due to sales taxes being about equal the difference in value between dollars and euro's, so 99 euro monthly, and 499 up front for the hardware. From the email:

Starlink is now available for order to a limited number of users in your coverage area. Placing your order now will hold your place in line for future service. Orders will be fulfilled on a first-come, first-served basis. During beta, users can expect to see data speeds vary from 50Mb/s to 150Mb/s and latency from 20ms to 40ms in most locations over the next several months as we enhance the Starlink system. There will also be brief periods of no connectivity at all. As we launch more satellites, install more ground stations and improve our networking software, data speed, latency and uptime will improve dramatically. The Starlink team will provide periodic updates on availability as we launch more satellites and expand our coverage area. Depending on your location, some orders may take 6 months or more to fulfill. To check availability for your location, visit Starlink.com and re-enter your service address. Thank you for your interest in Starlink and your continued support!

  • ..in theory, its possible that a low orbit network can ultimately provide lower latency than terrestrial solutions on average.
    • Really depends on what or where you're trying to connect to. If you're in South Korea playing Starcraft against another opponent in South Korea it's effectively zero ping. Unless you have a country that spans a massive amount of land (U.S. or Russia for example) or have mostly international traffic, the terrestrial network is probably faster.

      • If they can do satellite to satellite optical communication and the opponent is on the opposite end of South Korea, then the ping would be indistinguishable from ground fiber, maybe the ground fiber would be slower because light travels slower in glass than a vacuum.

      Each satellite supports IIRC ~20 Gbps of throughput and covers (ignoring overlap) a circle with a radius of 941km, which is ~2.8 million square kilometres. They'll achieve full global coverage pretty soon, after that adding more satellites are mostly about increasing the available capacity per square kilometer, as well as the benefits of having more satellites visible in terms of dealing with obstructions and failures.

      Consumers are going to be icing on the Starlink money cake. The big money is going to be in the commercial and government spaces. Washington state was already testing it out during their last wildfire outbreak and it was working well for them. Military is testing it too. Then there are all the remote, ass-end of nowhere facilities (gov and private) out there. Monitoring stations, oil fields, large commercial agriculture, etc. Once they get laser links fully deployed (currently testing on their polar orbit sats) it will be able to displace the really, really expensive sat services used in the marine industry. Plus the high-frequency traders are salivating over a sat-to-sat link from the major cities to the big stock exchanges.

      For consumers, I don't think that it will be much competition for Verizon or AT&T, at least no where they actually care about. Places that already have true high-speed internet are probably going to be too crowded for Starlink to be a viable alternative to those other ISPs. Even Musk has said it's more for lower population areas.

Your Starlink is assigned to a single cell. If you move your Starlink outside of its assigned cell, a satellite will not be scheduled to serve your Starlink and you will not receive internet. This is constrained by geometry and is not arbitrary geofencing.

          They do, actually. The system as a whole is very much targeted for fixed service right now. Beta users have already tried moving their terminals away from their official service addresses and they do stop working when they go far enough.

          The limitation appears to be in the routing algorithms, though SpaceX isn't disclosing details. The dish goes through a very generic automated orientation process when it is powered up, so there's no limit there. The system works out the optimal pan and tilt on its own.

If you mount the dish to a set of collapsible tripod legs it should be easy to move locations at will. If you have an RV or some other large vehicle that you are traveling with you could also just mount the dish to the roof and then let it auto-orient once you are at your location.

      Theoretically, Musk isn't overpromising. These don't use a curved satellite dish like traditional satellite receivers. They use a phased array antenna. A curved dish has one focus point, and you have to physically point it at the satellite for it to work. That's why satellites in geosynchronous orbit are so popular - they don't move relative to the Earth, so you can point your dish at the satellite once and forget about it.

      In contrast, a phased array antenna is flat. It's made up of a grid of small receivers, each operating independently. If you imagine a radio signal coming in from the side, it will hit some receivers before others. If you offset the receive time for each receiver, delaying it a different amount for each receiver so the signal hits them all "at the same time", then you've effectively "pointed" the phased array antenna at the signal source. You've synchronized and added together the signals coming from a certain direction, while desychronizing signals coming from other directions. This can be done in software - it doesn't require you to physically move the antenna or hardwire in some delay at each receiver. You can just buffer the signals each receiver receives for a short period of time, and pick and choose the signal each receiver recorded at a different time to "point" your antenna. Since you're only limited by the speed of your computing power, instead of the speed at which you can rotate a satellite dish, it allows you to quickly and effectively track moving targets like Starlink satellites (the military uses them to track and shoot down incoming missiles). That's what allows Starlink to offer service with satellites in low earth orbit, instead of geosynchronous orbit. The antenna they give each subscriber can track moving satellites via software.

      The real key though is something I've mentioned here starting nearly a decade ago, back when 802.11ac was first showing up. A phased array antenna allows you to bypass the Shannon bandwidth limit of a shared communications channel [wikipedia.org]. Normally if there's a shared communications channel - like satellite transmission frequencies - the broadcasts of one transmitter interfere with the broadcasts of another. Like multiple people talking at the same time in a crowded room, their voices all intermingle and it becomes difficult to pick out what any one person is saying. Much less what all of them are saying (something satellite Internet has to do since it has to hear and understand the transmission from all users simultaneously).

      Well, not only does a phased array antenna allow you to "point" the antenna in a certain direction in software, it allows you to do so after the fact, multiple times, in different directions. If you imagine a second signal arriving at our antenna from a different direction, it too will hit all the individual receivers, but in a different order and a different pattern. You simply take the signal data recorded by those receivers over a short span of time, process them again - this time using different delay offsets so that the signals from the second source all arrive "at the same time." And now you've effectively pointed your antenna in two different directions at the same time. Repeat for multiple directions, and you're able to "aim" the antenna at every person in the room who is talking, and amplify what they're saying while attenuating what everyone else is saying. And you can clearly hear what each person is saying (or what each Starlink user is transmitting). You've bypassed the Shannon limit by turning the single shared communications channel, into a bunch of point-to-point communications channels with minimal crosstalk (noise) between each channel.

      So that's the theory. It remains to be seen how well this will work in prac

    I live in the Bay Area and starlink.com says service is not available at my address. I always suspected that Silicon Valley wasn't on planet Earth.

  • I'll be purchasing Starlink as soon as I can. I live in a rural Ohio town that has had ONE option for the past 15 years and that option is expensive and stinks. Starlink costs a bit more but I'll be getting it just to spite these a-holes that have had complete control for years. I got my invite email a few weeks ago and I can pre-order if I wish. Bye-bye Spectrum!

  • As a rural customer with limited options right now 300ms would be a godsend. My current provider gives me around 40mb/sec but it varies wildly. Anywhere between 150 on a really good day to less than 1mb on a really crappy day. Outages are not as frequent as they once were (i.e. daily) but it's not as solid as I would like.

    I too got the email letting me know that I could sign up. The only hesitation is they did warn about possible outages as they exit beta testing. I'll probably wait until Q3 or Q4 of this y

    • As a Central European Rural Customer, all of 30 km outside the city limits, it would be a godsend also. The only option here is WiMax, which is maxed out - obviously. If Starlink service would deliver something better than 300 kbps (nevermind 300 Mbps), then I would be jumping with joy.

  • Slashdot keeps reporting areas blocking the entire Internet over local concerns of rebellion, so would all traffic from StarLink have to hit a ground station for censorship, or do they plan to go point-to-point? That's not how DBS Internet works in the USA.
