    About $300 million US of it per month. Greedy bastards. If they had some deal for Php300 to 500 per month for unlimited text, they'd still make a fortune. I'd buy in at that price point.

    It's copper for the electricity, and microwave for chatting back to the exchange. Unless some convenient copper or fiber based infrastructure already exists nearby, then radio links are nearly always used.

    SMS is sent over a 64kbps channel. Reduced in bandwidth and capacity compared to what? Given that it is simple to add more SS7 links, where is the problem?

  4. Re:A LOT of air on the prices on The True Cost of SMS Messages · · Score: 3, Interesting

    I spent a bunch of years working in the field, it was a rare site to see SS7 saturating a link. These days it is simple and cheap to add more SS7 capacity. You can already jam a metric crap load of phone calls down the bearer and still have lots of nice white space to spare for data. SS7 isn't much of a bottleneck at all. Certainly it's not the most elegant way to do SMS, but there really isn't that much competition with all the other dialing cruft that goes over the wire.

    I guess others might disagree.

    If you have the number of customers that would saturate your existing links, then you are also making more than enough money to add in more capacity.

    SS7 works well over pretty much any type of link. It's extremely common to see it on satellite, I think that would be about as unreliable as it can get, though you could get creative and try and do it over HF with a couple of home made transceivers and some bent up coat hangers for antenna.

    Maybe in the US it is taken as seriously as you say, but elsewhere the telco's really don't care how it happens, just so long as it almost always accurate and still turns them a stupidly high profit. Here in Asia it's quite common to see 8 or more SS7 links on a single E1, that's the popularity of SMS in this part of the world.

    It's technically more efficient to do SMS some other way, but right now it would seem bandwidth isn't so scarce that it makes economic sense just yet.

  5. Re:Article text in lieu of mirror. on The True Cost of SMS Messages · · Score: 1

    Perhaps the most annoying part is that SMS is just part of the standard payload for the dialing method used (CCITT 7) Normally this sits in a 64kbps time slot on a trunk between the cell tower and what ever is in range, another cell tower or the exchange. These trunks (T1/E1) generally have more than one SS7 running through them. Even in high density areas these things are not that busy.

    This transmission has to be present regardless of someone sending a text or not, so the infrastructure is already in place and paid for with normal monthly post-paid bills. As others have said, the size is somewhere around a thousand bits to max out the space allocated for SMS, these transmissions just tick over so there is a huge amount of waste happening.

    Ultimately I guess my point is that the whole text phenomena is an absolute gold mine for the telecommunication companies. Maybe not so much in the US, but here in Asia you don't often see anyone talking on their phones, just 'texting' It's cheaper than in the US though, 2 (US) cents per message sent, received is free. MMS costs about 4 cents to send, also free to receive. The telco's are logging around 11 billion messages per month combined, that's a crap load of money right there. ($272 Million US per month spread out between them and the tax man)

  6. Re:A new approach to limiting usage is needed on Time Warner Cable to Test Tiered Bandwidth Caps · · Score: 1

    Because it's a few orders of magnitude cheaper to jam a 30MHz wide analogue signal down the coax than it is to send the same thing at 10 or 20MHz in digital format. You're looking at perhaps 4 to 5 zeros on your bill for each modem alone, some modification is also needed on all amplifiers and other crud on the lines out to the customers. It's more expensive to set up, though the bandwidth savings mean more channels over the same wire, and ultimately more money in the long run.

  7. Re:Good on Time Warner Cable to Test Tiered Bandwidth Caps · · Score: 1

    The difference being: Once the electricity, maintenance, staff wages, golden parachutes, and a few other little bits and pieces are paid for, that chunk of fiber is pure profit, it doesn't make much difference if it is used right up to capacity or very little. The same cannot be said for resources dug out of the ground.

    Garmin Mobile XT will let you do this on its own with as many waypoints as you want to set. It is much easier to create the routes on a PC with a combination of various mapping programs though - I think Mapsource lets you define a bunch of points to route through, like others have said, it is a sequential solution, pretty handy though.

    My GPS handles this whole problem for me, I just feed it a few waypoints and it figures out some nifty turn by turn navigation to calculate the shortest distance or fastest travel time depending on traffic congestion, speed traps and limits, and so forth. It does connect to the net to get the latest traffic conditions though, so it's not completely self contained.

    WTF would the vast majority of people living in Australia right NOW need to say sorry for? Sorry for the atrocities a bunch of retards (many long since dead) undertook while the current population was, at best, running around in nappies with no idea about the world around them.

    Saying sorry is very probably a bad idea, it's an acknowledgment that will likely be followed by a bunch of arsehat lawsuits from a load of morons that are 6 generations down the line from the actual 'stolen' individual, though they'll still be taken seriously and wind up with a nice little golden parachute at the expense of contemporary society.

    Why would sorry need to be said now, almost 40 years after what is arguably the last occurrence? Why was it not said back then? And given that the whole issue is still clouded in huge amounts of controversy, the realities are likely to be a tad different. A lot of these children were abandoned by their own parents anyway, they were cared for by the government, not stolen. This is not to say it never happened, just that people should slow down a touch and open their eyes.

    Ahhh, yes, but I'm not in your back yard, so what you feel as unjust or otherwise is of no consequence to me. :-)

    While I can't speak for the NSA or US laws, in Australia anyone at all can set up an organisation like the Defence Signals Directorate. It is fully legal to monitor communications of foreign origin and destination. For private individuals the vast majority of domestic transmissions are also legal to intercept. (Some exclusions surrounding radio based telephony exist) The government does have far more restrictions imposed on what they can and can't do than the general population. The DSD is prohibited from monitoring all domestic transmissions - with some exceptions. Perhaps much less widely known is that it is entirely legal for the DSD to receive domestic non-communications type signals such as RADAR. The laws are all open for public viewing. Three letter agencies like the DSD are quite transparent in what they can and cannot do. How they do it is what remains secret.
