Two-Way Satellite Internet Is Here!

spectro writes: "Wired is reporting the first two-way satellite Internet service has been launched by StarBand. The service promises speeds up to 500Kbps down and 150Kbps up, but a ping latency of about 400ms, so gamers are out of the question. Anyway a nice alternative for those of us who cannot get DSL yet, but watch out... The Evil Empire is part of the joint venture." It's nice to know that someone has finally made the leap, after years of promises and millions of R&D dollars. Check out the article for information on some of the competition, too.

  40. What bandwidth limitations? by ZoeSch · · Score: 1

    While the article doesn't come out and say it, I'm guessing there will be serious total bandwidth limitations- since there are no tracking antennas, and since this is referred to as part of a satellite TV service, it must be from (and probably to) a satellite in geosync orbit. All traffic is probably going to just one satellite. Once a lot of people sign up for this- popularity will kill it- since I'm sure that they can sign people up to long term contracts faster than they can put more transponders up.

    You obviously don't know what you're talking about... The average transponder Bandwidth on the newer GEO satellites is 72 MHz, using 8PSK modulation with FEC 2/3 Viterbi or 216/205 Reed-Solomon encoding gives you roughly 90 Mbps to use... most High-Speed VSAT (Very Small Aperture Terminal) systems allocate bandwidth in two chunks, one outbound carrier (From the hub) and several inbound carriers (From the station). Those are TDM/TDMA slotted carriers where you should contend for available slots (Slotted-ALOHA) which usually have an efficiency of 60-65%. If you split the transponder in two you have 45 Mbps downstream (Subject to a 85% efficiency limit)and several (Usually 2-4 Mbps) upstream carriers which serve a group of VSAT's.

    Since you're using a multiple allocation mechanism you can effectively guarantee at least some upstream traffic per station using streams (Pre-assigned slots). Have too many users in your service, get another transponder, it's not expensive to implement since these kinds of systems have independent modems.

    Plus there is the fact that anything beamed to you is probably also being beamed to everyone in a multiple state area around you. I sure hope they have some *strong* encryption built in. They ought to be doing something better than DES, no?

    Oh brother... can you tell me how are you going to demodulate the signal you receive from the satellite? (QPSK and 8PSK are not easy to implement with a breadboard you know?, not taking into account the fact that you'll need to build a fairly big decoder for viterbi or Reed-Solomon plus the encryption on the timeslots). You will receive what's intended for you and only you... you will be expecting some downstream timeslots and your IDU (Indoor Unit) will only decode those.

    I hate to say it, but the microsoft backed Teledesic system is a much better system (many satellites in low earth orbit- kinda like a cellular system) the satellites are closer and cover smaller areas, so the amount of bandwidth/satellite is much smaller.

    Of course you don't mention that these satellites are smaller, have less transponders, drift like mad and have poor signal footprints (The amount of power you receive down in earth). Cellular systems only work for small amounts of data (Look at how painful it has been to get GPRS working, not to mention 3G). Of course, fixed cell systems like LMDS do provide better bandwidth but they use modified versions of ATM, Frame Relay or PPP in order to dynamically allocate bandwidth and those aren't good when you have 500 users downloading pr0n at the same time.

    If you need more proof that these kinds of systems work (Only for mail and browsing, trust me) look for DVB (Digital Video Broadcast) services, or check out systems from Hughes Network Systems or STMI.

    I should know, I've been working for a company that has provided two-way satellite internet since 1995. Several hundred sites, and a few thousand more in the works . . . So it's a misnomer that it's finally "here". But it's just now becoming consumer-targeted rather than company-targeted.

    There are software packages that can be used to significantly improve response even with such a large latency. Mentat makes such a package. You can't overcome the latency but you can use a proxy that converts TCP to a protocol better suited to high latencies.

    About the only thing "out of the question" on such a link is gaming. Other things might be slower but still possible.

(22,000milesX5280ft/mile)divided by 3ft/meter, divided by 300,000,000 meter/sec (speed of light) is about .3872 sec per leg (387 millisecs), but there's 4 legs on the journey, so even if the routers were instantaneous, you couldn't possibly have a ping time less than 4x.3872 sec = 1.5488 sec. That's rediculous. I was going to buy one until this, but not now... I guess majoring in chemistry paid off :>

The StarBand satellite that I have at work is basically attached to a server that interconnects all 300 or thereabouts of the stores that are on this same network. Our server is vastly overloaded at some points, and my times are claimed to be quite a bit slower than what real customers are experiencing from the beta test, and apparently now we have real paying customers getting into the service right now.

    Ping times: Ping times are rotten. I see anywhere from 850ms return time to >2000ms return time, depending on time of day and weather conditions.
    This makes it virtually useless for gaming.
    However, my experience with chat programs (I use PIRCH on it on a regular basis) with IRC and Yahoo! and such is that it's really not all that noticeable. I haven't tried ICQ, since ICQ operates a little bit differently than Yahoo Messenger does, I imagine it would show more of an annoyance factor with ICQ than with Yahoo or MSN Messenger.

    The other thing that's totally out is telephone applications.

    However, many improvements have been made in the service that I am seeing over the last several weeks. I've noticed that although in the beginning web pages with lots of small data files included initially were painfully slow, but over the last several weeks, the speed has increased dramatically. I don't know if they are using some sort of caching software that will take all of those requests, then respond to them with the burst download speed, or what.

    I do think that software caching certainly becomes a very important aspect of this, and that if you were using this 2-way satellite connection, that it would be a very good idea to have your own on-network caching and DNS service. On the computer at work that it is hooked up to, I have Internet Explorer set to not expire the cache at all, and use the Refresh button when necessary, since I don't have the privlege of installing decent caching or DNS software.
    I haven't tried much telneting with it, but I imagine that a Character mode telnet would be absolutely intolerable, though I have used MUDs that use Line mode telnet without any annoyance factor. (I should develop a scale for that.. the XO Annoyance Factor scale.. *laugh*)
    To the bright side of things: My system which, as I said, is supposed to be quite a bit slower than the consumer system, does return (using the MSN speed test page, I don't know the URL right off hand) speeds around 350k/sec download and around 100k/sec upload. It may take some time to get the data streams started, but once they are started, they are _FAST!_

    I can pull up NASA TV after a second or two delay in incredible audio/visual clarity, most real audio/real video things come down at maximum speed (I notice that a -lot- of RA content out there is optimized for 21k/sec, which leaves a SERIOUS amount of quality to be desired!), my customers who play with the system are on a regular basis amazed by it's speed, particularly if they are stuck with dialup or with a low-grade (ie 144k/max) DSL connect, etc.

    The only downside of this whole thing is, since it's very new, they are only offering it with one particular computer setup - though this is not necessarily a bad thing. The computer that you get pre-tested and ready to rock on this system is a Compaq system, I don't have the specs, it's around 600MHz with 64MB RAM, etc. Would make a fabulous network gateway for those of you with more powerful machines already, or a great upgrade computer if your main machine is an older one (like mine's a very nice 400MHz with 96MB.. when I get the satellite setup, I'll be hooking up about 6 other machines to it, all inferior computers)
    . The other thing that my system has is that my system is running Windows, and has to use CyberPatrol, with full blocking on. So although I imagine that it could very easily be configured for use with Linux, and such, the software isn't immediatly available.

    The hardware to actually operate the satellite dish is in the form of 2 (two) PCI cards, one dedicated for transmit, and one dedicated for receive. (You may notice that they are currently being sued by another company who holds a patent on something like "receiving and transmitting data into/out of a computer using two seperate interface cards" - a BS patent if I've ever seen one) I would very much love to see OpenSource software to handle these cards, and although I haven't been a Linux user for quite some time (Windows gets me by just fine for email and reading slashdot which is all I ever have time for anymore), I would seriously love to provide any information that I can.

Now when you're doing a stream of data in, this isn't so bad. You have a half second latency when you're setting up the connection, but then you have a nice even data delivery. However, for things like web surfing where you're setting up lots of connections (up to 30 or 40 per page sometimes), it's unbearable.

    Satellite internet connections are useful if you're in a remote area and can't get anything else. But if you have anything else, even IDSL, you're going to find it a better choice for things like web surfing and gaming.

      It probably isn't as bad as you suggest. You shouldn't be seeing 30 to 40 connections to pages with modern (or at least future) browsers and servers. After getting the HTML, the popular browsers usually open up 4 to 7 concurrent connections which incur the round trip times in parallel and then reuse them for subsequent requests when possible.

      I'm sorry, perhaps I wasn't clear when I said that I installed and used this setup. The particular site we were using was washingtonpost.com, which at the time averaged 50 objects per page. It wasn't the worst site out there (ICQ was much worse), but it definitely wasn't the smallest pagesize.

      Even if you have 4 simultaneous connections and reuse them, you're still incurring large delays. To set up the TCP connection, you need a three way handshake. That is a minimum of 1.25 seconds (given .5 seconds for a round trip). Then, best case scenario, you send a request and get a response for another 1 second of latency, plus any latency present between the satellite headend and the website. Let's assume 40 objects on the page. So each connection has to get 10 objects in parallel with the other connections. So that's 1.25 seconds to set up the connection, and 1 second per image. That's 11.25 seconds of latency per page added by the satellite connection. Theoretically, if you send all the requests at the beginning of the connection, you can reduce that latency. However you still have a minimum added latency of 2.25 seconds, and it's questionable whether or not you can do that with current browsers (I personally don't know).

      In contrast, if you open up a dialup connection to an ISP without caching or compression and pull washingtonpost.com's front page, it will take about 11 seconds to download and render the page. That number is based on a series of tests that I performed personally, using several different computers to make sure the number was accurate.

      Also, if you're wondering where I got a half second for a round trip from, it's fairly simple. The satellite is located 22,500 miles above the equator. Given a best-case scenario with both you and the satellite headend on the equator, that's a one way trip from you to the headend of 45k miles, and a RT of 90k miles. The speed of light is 186,300 miles per second. So that gives a best-case latency of about a half a second.

  134. Buzzword Security by _Sprocket_ · · Score: 4
    From the article:
    The DirecPC system uses 56-bit encryption on the packets of data that are sent downstream from the satellite, according to Steven Salamoff, assistant vice president of the DirecPC business services division. Deciphering upstream packets would first require breaking the downstream encryption because of its random packet generation, Salamoff said.
    Consumer awareness of home computer security is growing. And it looks like the DirecPC salesforce is chomping at the bit to try out their service's embeded buzzword: encryption. Yep. They're safer than that Cable and ADSL you hear about. Unlike those guys, satalite providers encrypt their data.

    Sure, wireless brings forth a whole new series of security concerns. And that means encryption has its part. But it does nothing to address insecure hosts on persistant broadband connections.

    What do you want to bet that the new satalite service providers will do the same as their xDSL and cable competitors and ignore this problem. But hey... they have encryption.

  135. Geostationary Broadband Services by Baldrson · · Score: 4
    In late 1991, as vice president for public affairs at E'Prime Aerospace I did a lot of the work to break up the log-jam within the FCC on the first Ka-band satellite license ever to be issued. It was for a two-way geostationary broadband system called "Norstar" that was based on Milstar satellite technology. The way these geostationary systems work is to use a phased array antanna on the satellite to rapidly multiplex a tight spot beam between ground stations and dynamically shift the time slices to various geographies based on load requirements.

    The higher the frequency allocated for the service, the tighter the spot beams with a given dish diameter, which means you can end up with the geographic equivalent of a dynamically distributed cellular communication system deployed via a single satellite with the main drawback being that you are sharing a single point of failure as well as a bandwidth bottleneck. However, at these high frequencies satellites can be parked much closer to each other in the same orbital so the bottleneck and failure vulnerability can be minimized by requiring a bit more complicated ground station to allow a fixed dish to rapidly switch between co-located satellites.

    The rain problem is serious, but can be minimized, at least on the downward leg, by increasing the energy storage capacity of the satellite to power through the weather. IIRC the upward leg has a bit more of a problem with heavy weather because, although power is quite available on the ground, the scattering occurs far from the satellite (clouds are only a few miles in altitude whereas the satellites are about 20 thousand miles away). On the upward leg it is a bit more problematic due to the fact that arc very tightly which further increases the density of communication via demultiplexed (parallel) communication channels.

    The delay time introduced by going up and back is less than typical human reaction time (about a quarter second) so its just fine for most practical uses -- even interactive ones other than games where people are pushing human reaction times to the sub 100ms ranges.

    Starband is probably in these high frequency ranges since they do have a bit of difficulty with heavy weather, although I haven't been able to locate their FCC filing online to see exactly how high the frequency actually is.

  136. one pipe- bandwidth limitations by Matt_Bennett · · Score: 4

    While the article doesn't come out and say it, I'm guessing there will be serious total bandwidth limitations- since there are no tracking antennas, and since this is referred to as part of a satellite TV service, it must be from (and probably to) a satellite in geosync orbit. All traffic is probably going to just one satellite. Once a lot of people sign up for this- popularity will kill it- since I'm sure that they can sign people up to long term contracts faster than they can put more transponders up.

    Plus there is the fact that anything beamed to you is probably also being beamed to everyone in a multiple state area around you. I sure hope they have some *strong* encryption built in. They ought to be doing something better than DES, no?

    I hate to say it, but the microsoft backed Teledesic system is a much better system (many satellites in low earth orbit- kinda like a cellular system) the satellites are closer and cover smaller areas, so the amount of bandwidth/satellite is much smaller.

    I rember when i thought light (186,000 miles/second) was fast haha. Now 400ms a second isn't round trip time for light from nowheresville -> Satellite -> Backbone router but the handicap makes up for a damn sizeable chunk

    Let's investigate.

    For example, if the mission requires a geostationary orbit, which can be achieved only at a distance of about 35,000 km (22,000 mi) above Earth.

    I got this from MSN Encarta. MSN... like their operating systems, probably can't be trusted :).
    Lets do some calculations(my favorite). For light to get to the satellite it takes .118 (approx) seconds now multiply by 2, we have to go both ways. we have .236 seconds (approx).
    Now a handicap of 236ms before you get on the net leaves a little to be desired. Like, Damn I wish light were faster.
