Satellite Internet Providers 336
pitchblende writes "Our company works in remote locations in Northern Canada. We have been experiencing major communications problems with our current satellite service. We use satellite systems that go for about $1000 apiece, with $100/month in fees. The service is 'shared' rather than dedicated, and our VOIP, etc, has been getting worse by the day lately. From what I can tell, dedicated systems go for $30k and up.
I hope someone(s) out there has some suggestions, recommendations?"

The only solution to this problem is to try to secure some premium class traffic for sending VoIP and have the border gateway properly configured to mark VoIP packets accordingly. The rest of the traffic should be served as Best Effort, in order to save money.
Satellite contracts and providers (Score:3, Interesting)
Are you dealing with the satelitte provider directly? i.e. infosat, telsat, etc?
Directly they won't do much in the way of service level agreements that have financial penalties associated with them. However, if you were to purchase network services from a communications supplier that was working along with your satellite provider, you may find they have more weight in getting you the service levels you are paying for (and contracted).
I suggest you give TELUS a call, and compare prices/service levels for service in your area.

If a cellphone network is available for some of your locations then look into that.
I have wildblue, which could be similar to the system you are using (costs are similar). A couple of years ago it was a lot better but since it has been more loaded I am not always getting my bandwidth and the latency has gone up.
Two years ago VOIP was somewhat usable now I am very lucky if I can use it. Any SSL has always been painful.
My situation has changed since I provisioned the sat. I am now running a small business from my home and when I move I will probably go back on the grid. If I don't move I might try putting up an antenna and routing some of my data over a cellular network.
Teleco (Score:4, Interesting)
Depending on where you are, Enerconnex offers some kind of service to remote locations though its primary target is oil and gas in northern Alberta. I don't know if that particular company can help you. It is a division of Northwestel.
You might also want to contact Northwestel directly but seeing as it is a government-sanctioned monopoly with a government-sanctioned profit margin, I wouldn't expect much help. It's probably cheaper to blast your own satellite into orbit that to get service from it.
Also, Northwestel should read Bell as Bell wholly owns Northwestel.
Satellite is pretty much the only system that you can get from another company, at least in the Yukon. Northwest Territories and Nunavut may have different telecos that don't suck so hard. I'm strongly considering getting satellite for my own personal internet just because I loathe Northwestel and its business practices.

You simply aren't going to get good performance out of a satellite internet service. It might be acceptable for simply web-browsing and e-mail, but for a business? Forget it. It's strictly a "we have no other choice" option.
You're screwed, basically. If you want a good internet connection, you need something that is based on a good ol' cable, whether it be copper or fiber. If you don't have those available, then you need to build them. If you are really in the boondocks of Canada, then expect to pay millions to lay your own fiber.

Get with some of your local ham radio geeks. Those guys are amazing. Granted, their radio bands and equipment are not approved or licensed for commercial use, but they can probably at least point you in the right direction. Once they get the equipment (which is way less than $30k) and license, they can toss packets all over the place for free. I don't know what the bandwidth or latency is like on their systems, but I do know that when it comes to getting information from point A to point B, they get pretty creative. Certainly they can help you come up with something that will fit your needs (for a nominal fee). Worth a shot!

I had a satelite before.. ping times well over 1200ms.
Smells like something funny on the provider side. I assume the satellite was geostationnary (35786 km from earth). So given that the signal travels at the speed of light, a RTT between you and the provider hub should be:
35786 / c * 4 * 1000000 = 477ms
4 being the times the distance is travelled (modem->sat, sat->provider, hub->provider, sat->modem).
Of course the signal travels a bit less fast, and there's some processing at your providers but I've seen results around 600ms.
Weren't the 1,2 sec RTT you're talking about between two sat modems? That would explain such a huge delay.

Pay enough money and you too can get a dedicated T1 thru satellite, and run whatever you want over that T1 such as inet access. Obviously this is how the telcos used to provide satellite voice service.
I hear there are also gadgets that encapsulate ethernet frames into something that looks like an MPEG stream and can be multiplexed and demultiplexed with the TV signals off a tv transponder.
If you are just too rich to know what to do with yourself you can rent the entire transponder. You will be bankrolling a significant portion of the total cost of a satellite launch, but T3-ish speeds or perhaps a half dozen video channels are possible off the shelf.
Either way, the telecom style T1 or the TV network style MPEG stream is of course terrifyingly shockingly expensive. As in if you have to ask, you cannot afford it, so don't bother. Your employee's employees will take care of setting up the ground station, running waveguide, replacing TWT tubes (do they still use those or have they gone all solid state now?) maintaining positioners, keeping N2 pressure regulated in the waveguides, filing FCC licenses, etc. The 30 foot dish will be an attractive addition to the top of your skyscraper but will often get in the way of your heliport.

Manitoba Hydro [hydro.mb.ca] built, maintains and operates two microwave networks that run from Winnipeg to the north. They use them to control northern dams from the central control office in Winnipeg. I know someone who was involved in the implementation of remote switching of manually operated dams back in the 70's who was actively involved with the microwave system. He said the latency is VERY low. They can switch things almost instantly from Winnipeg, over 1000km away.
They have used it in the past (maybe still do) to send TV and radio signals to repeaters up north so the folks up there could watch live TV/hear live radio. They also use it for phones as well until quite recently (upgraded to fibre optics since). Which is why the phone company (MTS [www.mts.ca]) helped pay for/build it too. Much cheaper than running thousands of kilometers of copper. The guy I know had a friend in the control office in Winnipeg who sent up various Winnipeg radio stations over the microwave on a subcarrier of the CBC TV signal. Apparently the CBC never even noticed hehe. I think they had to modify their radios, but there were all electronics specialists anyways working on the remote switching stuff, so it was peanuts for them.
I'm not sure where the poster is located or where his remote sites are, but perhaps there's a utility company that might have some spare capacity on an existing microwave network they'd be willing to sell?

I lived and worked in the Eastern Arctic between 1994-97, so my information is somewhat dated, but at that time, 1.2 seconds was an average round trip time, because in order to reach our Internet backbone in Yellowknife, we had a double satellite hop. For reasons that the Northwestel techs were never able to explain, traffic coming from Baffin Island landed in Northern Ontario, then got shot back onto a satellite in order to send it to Yellowknife.
Back when we created what was at the time one of the most remote commercial ISPs in the world, we paid the telco CAD 3000/month for the privilege of a 56Kb digital connection. I asked about T1 (or equivalent) and was quoted CAD 100,000/month.
Nonetheless, we managed to provide service to about 1000 customers, creating a few IRC junkies in the process. Believe me, any service at all was better than none out there.
More on topic: Jeff Phillipp and the guys at SSI Micro [ssimicro.com] (based in Fort Providence, but with a presence in Yellowknife) are the best people in the region for Internet connectivity. They did pioneering work getting the diamond mines' communications systems up and running, and have since developed processes that have been used everywhere from the Arctic to Africa to the South Pacific. They know exactly how to squeeze value out of any Internet connection. I can't recommend them more highly.
My experiences from Afghanistan (Score:3, Interesting)
512 down 128 up dedicated, 1.2 meter dish (I think, could easily be wrong on the dish), ended up running about $30,000 U.S. a year. About 2 people could fired up Vonage VOIP and get a decent connection, any more than than and things went bad. Ping times were 675-800ms when the link wasn't too saturated. We had upwards to 18 different people sharing the link, so it was often saturated, especially in the evenings.
We looked at several different companies, and found some 256 symmetric shared (duno where the sharing took place, ISP or satellite, or what) connections for a little cheaper, but when we tried those out, they were all but unusable.
Getting decent bandwidth and low latency to the ends of the earth isn't cheap, reliable, or effective. It wouldn't surprise me if the middle of nowhere northern Canada had an equally poor satellite footprint to Afghanistan.

If you're paying $100/month for shared segment you are probably getting some crap service. I work with three different hubs (Telesat directly, a telesat reseller, and Hughes in the US) and even for a 64kbps symmetrical service I spend considerably more than $100. I generally see 600ms latency on these links. These are on iDirect iNFINITY 3000 series IDUs with 1.8M dishes. I believe 512kbps/512kbps service was something like $500/month (i'd have to dobule check).
Leasing space segment isn't worth it IMO unless you have a bunch of sites with very low bandwidth requirements. If you are doing VOIP and video conferencing this is not the case. Most providers can give you a CIR on a shared segment which will definitely help applications like VOIP and Video. But you get what you pay for. $100/month won't buy you much in the satellite world.

Although VOIP will not work reliably, VSAT is an excellent options when there are no others excpet dialup. I used www.starband.com for 6 years before moing to a location with broadband. Down speeds were awesome, up speeds OK, packet turnaround time sucks for VPN and any other packet-exchange protocol.
Starband uses a protocol accelerator (BST - Boosted Session Transport) that blasts loads of packets at once and then blasts the check sums. Allowing large data transfers to take advantage of the high speed burts that VSAT uses. I have, on occasion, had speeds up to 25 MB/S; I am not joking (that is MB/S not mb/S)! However, 1 to 4 megabits is normal.

VoIP aggregation over satellite - use Asterisk (Score:1, Interesting)
I've recently been talking to some folks about their satellite VoIP usage in N. Canada and they're using Asterisk to aggregate their VoIP traffic for savings. This of course doesn't improve latency, but it does allow you significant improvement on bandwidth efficiency.
A G.711 ULAW 10ms RTP stream (typical "toll-quality") is around 82-85kbps, about 16kbps of which is the IP headers surrounding each packet and around 64kbps is the "speech" part of the data. That's a lot of data, so typically calls are compressed using something like G.729, so that the "speech" part drops to ~9kbps. But the IP overhead for those more efficient streams is the same as with G.711: 16kbps. The total bandwidth of a G.729 stream is now ~24kbps, but two thirds of the traffic is IP header. This is Bad. Adding more simultaneous channels of speech over the same link just gums up the bandwidth with IP headers and relatively little is used for the speech (important) part of the transmissions.
If you've got an Asterisk system somewhere at each 'end' of a sat link, you can use IAX2 trunking to stuff multiple channels of "speech" parts into a single set of IP headers. You still use 16kbps of IP headers, but each incremental G.729 channel only takes up 9kbps more data on the pipe instead of 24kbps.
For a comparison of various codecs using IAX2 trunking, see the study I did a long time ago here:

Yeah, we ended up using an UPS to try to alleviate the issue. It works alright, only problem being that the thing is a bit of a power hog. The entire system consists of the dish itself, the modem that it mounts onto, a NIPR box (regular non-secure internet), and the SIPR box (secure internet). Both the NIPR and SIPR boxes have their own routers, toughbooks, and various other electronic items. It all adds up to a healthy draw, so the issue we run into is when power is out for more than a few minutes, the UPS has trouble keeping up. While a bigger UPS would likely solve the problem, it was hard enough to get the government to buy the ones we got. We did find the running a seperate ground from the dish helps, which tells me that the generator likely is not grounded properly, but that's not my department.
Re:Amazing (Score:2, Interesting)
One other thing both of you are missing is the elevation above the horizon and how that affects path loss. Remember that microwave frequencies are heavily absorbed by water and, at Ku-band, by oxygen. So not only are you further away as you move away from the equator, but you're also having to pass through more atmosphere as well, and since northern Canada tends to be rather wet, it's not hard to understand why this happens.
The standard answer is a bigger dish and a tougher mount to make sure it doesn't move because of the reduced beamwidth. But as you get REALLY far (above the Circles) you start seeing diminishing returns. I know this because I read an article a couple of months back, referenced here in /. , about an Antarctic research camp and how, despite a huge 10+ meter dish (I don't remember exactly how big but it reminds me of an old 10 meter dish that was once a cable headend and was used for a while by a PBS station I worked at in the early 90's), connectivity was very intermittent so they have to use Iridium much of the time (who's polar orbit works best at the poles, but has a very low available bandwidth).
If you can suffer high prices and lack of bandwidth, you may want to seriously consider Iridium: each channel is only 2400 bps, but my understanding is that it's fairly easy to bond them. The trouble is that the price is per minute, not per kilobyte.
If you need more than this, you'll have to wait until 2010-2012 when both Iridium and Globalstar will be launching new technology to replace their constellations. I have no idea if this will increase speeds. And while Globalstar is cheaper, it won't work well above the Circles and won't work at all above 70 degrees (the orbit inclinations are very different, more like GPS's). Just remember not to use Globalstar now since the birds don't work (discussed in /. and elsewhere extensively).
I hope this helps at least somewhat.
