SatPhones — Why Can't They Make It Work? 337

RedEaredSlider writes "Satellite phones aren't as clunky as they once were, and technology has made them more powerful. Gone are the days when satellite phones had to be accompanied by a suitcase. Yet to date, the field is littered with bold attempts at a phone that could be used anywhere, without depending on earthbound cell phone networks. Billions have been invested, with relatively little to show for it. Part of the answer is debt. TerreStar is only the latest casualty of a crushing $1.2 billion debt load. The company introduced its Genus phone last month, but is in the middle of Chapter 11 proceedings. It's unclear that the phone will sell enough to help TerreStar stay in business, especially when it carries a $799 price tag."

    What other phone can boast of having a full audio archive of every single phone call you ever make, courtesy of the NSA? Carrying one of these puppies comes with the cool prestige of being able to hit on the classy girl at the bar with James Bond lines like "Either I *am* a spy, or I'm getting spied *on*--that's for you to decide, my darling."

      At least one of the proposed LEO satellite networks ran into real problems because lots of governments insisted that they route satphone traffic from that network's customers in their countries through earth stations in their countries. It was partly security paranoia (like the recent Blackberry regulations around the world), but largely protectionism for the monopoly telcos, which didn't want to lose revenues from people who could use satphones to save money. (Typically this was third-world countries with poor infrastructure and government-run telcos, which were one of the big markets for satphones.) Remember when calling India cost a dollar a minute?

      I sometimes talk to people that use these phones up in Northern Alberta. The quality is actually far better than you would expect, and the delay isn't too noticable. I think the phone the other guy was using was on the Iridium network.

      I think that the problem with these phones and why they will never take off is that they will never be cheap enough for mere mortals to use. They just don't have enough bandwidth to have the unwashed masses using it to talk about the latest celeb gossip. With a space based solution, it would be hard to break geographic areas into cells like what is currently done with cell phone tech. The result is that everyone is on the same tower, and there is only so much signal to go around. Because supply is so tight, price has to remain high.
      • Exactly. I wouldn't say satellite phones are 'failing'. But they are simply a niche market. You use the right tool for the right job, and a satellite phone is a tool intended for use in remote locations. There are better and cheaper technologies (i.e. cellular) for widespread use in more densely populated areas.

    I've worked in the industry for the past 7 years or so -- most of the support calls that came in were related to the fact that the phone would not work indoors or in a car.

This is small fact is one of the reasons, not to mention the cost, that satphone adoption has been stagnant.

      I second this. I also work in the industry and people generally don't know that not only do you have to be outside, but you have to have a clear line of sight to the sky and not be near obstructions like buildings. Also, the higher off the ground you are, or the higher the elevation, the better. Even in the best conditions, the call quality can vary as a satellite goes over the horizon and passes your call to another satellite. Also, satellite calls are very expensive, and the hand held units, although getting smaller (like the Iridium 9555 handset), are still bigger than a large cell phone.

      Not just that, but the infrastructure you need to build is just staggeringly expensive. Cell towers are bad enough, but at least they're on earth and can be easily built and repaired. To get full satellite coverage of the earth, you either need a whole pile of satellites in LEO (Iridium uses 66 with several spares) or a couple massive ones with amazing antennas in GEO. Iridium's satellites are considered amazingly cheap, and they still run over $5 million each according to Wikipedia- that's $350 million just for the satellite hardware, and launch costs are going to triple that. Tack on running and replacement costs, the costs to design both them and the phones....

      I'm honestly amazed anyone bothers.

          It's not a direct comparison, AT&T-s network has a much higher aggregate capacity.

          The Iridium satellites can only handle 1100 concurrent phone calls each. While there are 66 active satellites, most of the coverage is over the poles because of their orbits, so the capacity over occupied land is much lower than one would think, probably below 10,000 concurrent calls. Each of those channels in turn is very narrow bandwidth, about 2400 bits per second, and uses heavy audio compression to make speech intelligible. This explains why Iridium plans are so expensive. They're not for "chatting", they're for professionals that need emergency communication in the middle of nowhere.

          The iPhone in my pocket has a higher bandwidth for a single connection than an entire Iridium satellite!

    Saying that the problem is 'debt' is just another way of saying that the value of the service over traditional cell networks isn't enough to outweigh the enormous initial investment required.

    Which makes sense. Satellites are enormously expensive and only a handful of people really get any benefit over a normal cell phone. For those who do find a benefit, there are more cost-effective ways of dealing with communication than launching dedicated satellites into orbit.

When you are there you don't really need to call, unless in emergency (and in that case it's only to say goodbye). But you do want to post regular updates (be it email or web), but what data access you had was much worse than SMSs: 150 chars and you had to sync with the sat timing orbits. We later figured out that 9 out of 10 of our messages just went to the bit bucket.

    Maybe I'm missing some subtleties, but "why can't they make it work" doesn't sound like a real question. It sounds like a literary device where the author asks himself a question that he can then answer, without having to sound like he's just sounding off on an obvious subject that everyone already understands.

    But if not, I can hazard a guess why sat phones haven't taken off. Cost. Putting satellites in orbit is exponentially more expensive than putting up terrestrial towers. It's always going to cost a LOT more than cell phones. Combine that with the fact that the market of people who NEED sat phones because cells aren't good enough is very small. So you end up with expensive infrastructure, plus very small user base, that equals enormous individual consumer expense.

      Not to mention the power requirements in the hand-held to reach a sat in a 475 mile high orbit has got to be way higher than reaching a cell tower 1 to 20 miles away.

      So in addition to the need to be outside, you have a short battery life, and the cost of calls is also high.

      For anyone in the North America this generally means the market is limited to off-shore boaters and a few places in the western US and far northern areas of Canada.

I would be more than happy to make that initial investment for the phones if I could buy minutes that don't expire in 30 days. I would only need the phones 2-3 times a year. It's the cost to use them that really hurts. Think of the number of people that would buy one if the minutes either never expired, or you could pay as you go. I can think of a bunch of people that would love one in case of emergency, but don't want too have to pay a monthly fee for something they will never use.

    While their cost in strict $/km^2 terms might actually be pretty reasonable, satellites are a pretty horrid form of infrastructure in most other respects. Maintenance is difficult, launches are costly and don't always go well, latency is inherently bad, capacity is low, signal strength can be an issue and so forth.

    Therefore, anywhere with more than a relatively low density of people who aren't penniless and living in their own filth and an absence of militias blowing up cell towers with impunity already likely has a superior GSM network of some sort.

    Satellite has its niches, they just aren't big enough to spread the fixed costs, thus making calls extremely expensive, which doesn't make the niche any bigger. At present, the only reason they exist at all is that foolish investors took a huge bath on the project and then the corpse was snapped up for pennies on the dollar(almost certainly just so that the CIA could continue to chat with their BFFs in assorted hellholes without interruption).

    I work in the aerospace industry and though I haven't been involved closely with any of the major programs (Iridium, Globalstar, TerreStar, SkyTerra, ...), I'm familiar with Thuraya which is apparently making a profit ( As others have said, satellites cost a lot of money, and many large systems were thought up anticipating a given customer base and willingness to pay for monthly charge and minutes that just wasn't there by the time the systems were operational (I believe this was due to mis-predicting cellular network penetration).

    At this point, I don't know if any non-GEO systems will be profitable in the future. GEO satellites are really expensive, but at least you only need 1 (with a spare) to server a pretty big market (like the Middle East, parts of Europe and Africa). The bummer about GEO though is in addition to latency, you may not have coverage in many situations (high latitude, obstruction from hills, trees, etc.). What I'd like to see is a LEO network with satellites as cheap as possible that provide store and forward text/data messages only. Orbital Sciences tried to get this market with ORBCOMM (, but I don't think their market ended up as big as they hoped for either. What you really need is just about every cell phone on the planet carrying the hardware needed to interface with the satellite (which means it has to be a small and cheap addition to standard phones). Then every user can opt to use the satellite system to receive or send email or text messages when outside of the terrestrial network (when you are willing to pay extra). I would think this is a fair amount of money to capture, but I haven't done any estimates. It would fit my customer pattern perfectly since I normally wouldn't want to pay a monthly fee, but I'd probably send a few 1 dollar emails if the situation required it. Whether the world aggregate demand is in the 100s of millions of dollars for revenue per year is the question.

    "Why Can't They Make It Work?" was answered in TFA. Satellite phone service is capital intensive and has a small market.

    In many industries you make up for capital costs by increasing the size of the market, but you can't easily do that with sat-phones. There are real constraints both in the number of satellites (there are more than 200,000 cell towers in the USA -- Iridium has 66 satellites to cover the globe) and in bandwidth. AT&T can use the same cell frequencies across the USA because they know that phones associated with a particular tower won't cause interference with those same frequencies a few miles away. (ok, CDMA and other spread spectrum technologies makes this more complicated but the same theory applies - there is a limited to how many users you can handle within a particular frequency band). A single satellite covers a huge area - whereas a cell site may cover a few square miles (or less), a satellite may cover many thousands of square miles.

    Even if you could physically launch 100,000 satellites to give global satellite coverage and carefully tune their antennas to minimize overlap, unless you can find a geosynchronous orbit to park them in to concentrate coverage over populated areas, each satellite would still cover 2000 square miles or territory.

    For someone who lives out in the boonie's, this may be the only solution for those who need some form of communication. Very few places who can't receive cellular service, cable, dsl, etc, have to rely on the satellite service. As many of us who have ever had to work with Hughsnet or any other satellite internet service... well it blows! The reason they are not as successful as cable and dsl is because of the cost of the service, the quality is poor (by poor I mean it fluctuates from time to time), not to mention they all use this fair use bandwidth limiter that once you exceed a certain bandwidth, they take away the high speed and leave you with the bandwidth of a 14.4k datafax modem. Think XM/Sirius satellite radio. Think of Direct TV and Dish Network. Satellite phones work similar to how we get our XM radio or DirectTV. My XM satellite radio goes out everytime I enter the parking garage or go through a tunnel. And DirectTV gets flakey during a storm. The reason hughsnet stays in business is partly because of people who live out in the middle of nowhere. There are no other options for them. If hughsnet was able to increase the quality of their service, reduce rates, and remove the whole fair use bandwidth policy, they might be able to compete with cable/dsl. Same with the satellite phone. Now it may be much cheaper to put up a cell phone tower as opposed to launching a satellite in orbit, but i have yet to see anything that makes the satellite phones any better than cellular phones as far as reliability. Now that I can walk into an elevator and still talk on the phone, I wouldn't want to have to go back to saying "hold on, i'm walking in an elevator. I'll call you back" because of reduced quality.
  • Is sat phone ownership illegal in China, Iran, etc.? More to the point, do the sat phone providers cooperate with the countries where the calls originate from (block calls, turn over records, etc.)?

    I imagine fast-cheap-discreet-and-out-of-control sat phone service (not to mention fast-cheap-discreet-and-out-of-control sat internet service) would be a headache to many of the world's republics. Is such a service physically feasible, like "millions of simultaneous users" feasible?

    I have some friends who have rent sat-phones to go hiking in remote areas. It's amazing for peace of mind. They actually used it last year after being cut-off from the road by a storm. They were able to use the phone to notify relatives that they'd be late a couple days.

    But the # of people who need this is relatively small compared to the immense cost of satellites. Of course, the biggest users of sat phones aren't the occasional hikers. I think it's the government and resource extraction sectors, e.g. mining firms.

    I wonder, could someone launch a SMS only satellite service based on only a few geo-sync satellites rather than the 66 (!) that Iridium launched? With texting only, the extra lag and a few dropped packets don't matter (as long as it re-sends them later).

  • It goes like: "These phones work everywhere" or "These phones work where there's no other signal"

    Let that second one sink in for a moment, by itself it's almost breathtakingly salespeakish.

    Then the truth:

    "not only do you have to be outside, but you have to have a clear line of sight to the sky and not be near obstructions like buildings

    So they DON'T work EVERYHERE. I'll not bother to ask them to work underwater. Just working where my cell phone does not would be cool, but that won't be in my living room.


  • It costs billions of dollars to create a satellite constellation.
    It costs hundreds of millions per year to maintain a satellite constellation.
    Most people are far better served by cellular.
    The phones themselves are bulky, and the power output necessary would induce (more) RF-hysteria in (more) idiots.
    There is a vapor-trail of bankrupt sat-phone companies which have taught the lesson to potential investors.

    In other words, the cost people are willing to pay is far less than what it costs to provide the s

  • which costs the same as a sat phone, but with no ongoing call costs, will probably do better than a sat phone anyway - especially with the latest digital technologies. Even some of the less recent digital modes eg psk31 are probably better than sat phones in physical conditions that block sat phones, such as under forest cover. Unfortunately there are no (to my knowledge anyway) cheap/free digital voice modes available for HF radio and mere mortals yet.
  • The traditional utility model is not being used. The companies are not operating like a traditional utility and they want to recoup the investment to fast. But if they deployed a multi-billion dollar earth spanning network and then had a service plan that was competitive to terrestial cell-tower based service, or partnered with a terrestrial provider (to lessen satellite loads) then they could offer subsidized phones at competive rates for longer term contract commitments, especially if they open the phone
