Analog Cellular Shutdown To Hit Built-In Devices 173

Posted by kdawson from the can't-hear-you-now dept.
Nick Kilkenny sends us an AP article on the imminent shutdown of the US analog cellular network, now 24 years old. The network is scheduled to go dark on Feb. 18, 2008; some users, such as OnStar, are stopping analog service at the end of this year. Here's a list of devices and industries that will be affected by the shutdown. (Cellular telephony won't be affected much.) "The shutdown date has been known years in advance, but some industries appear to have a had a problem updating their technologies and informing their customers in advance... General Motors Corp., which owns OnStar, started modifying its cars after the 2002 decision by the Federal Communications Commission to let the network die, but some cars made as late as 2005 can't use digital networks for OnStar, nor can they be upgraded. For some cars made in the intervening years, GM provides digital upgrades for $15." Update: 12/22 22:25 GMT by KD : Replaced two registration-required links.

      Why do people insist on capitalizing "ham", as if it were an acronym? It's just a nickname, if you will, for amateur radio operator. You don't see GEEK, or NERD, or QUILTER.

      • Well, because otherwise they might think it refers to pig meat ? Maybe we should get rid of capital letters altogether :)

        I humbly apologize and will never use HAM again but will in the future refer to 'persons that have amateur radio communications as their hobby' ;)

        • Well, because otherwise they might think it refers to pig meat ?

          I agree with you. Uppercase "HAM" is for radio operators and lowercase "ham" is for little piggies. The only time someone should use "ham radio" is this site:

      Range, maybe yes. Though lower power it's also less susceptable to interference. So perhaps the range from the tower to the phone is comparable, despite the factor of 6 power difference.

      But coverage? Hell no!

      To convert equivalent range to equivalent coverage you have to convert all the cell sites to digital. This has NOT happened.

    The main reason I disapprove of this closure is the existence of 3 watt car phones to which there was NEVER any digital replacement. These are ideal for backwoods environments. Looks like there are boosters but still it's a bit of a hassle.

      We had a massive incident here in Australia where a plane came down in the bush, noone for 100's of kms. The pilot had both analog and digital mobiles. The unfortunate thing was that he had no digital coverage and the closest analog tower had been shut down. Pilot & passangers all died from exposure and it came out that if the analog tower was active they could have made a call to get help.

      The digital tower had actually taken the spot of the analog tower. This gave us another few years of analog and a dodgy attempt to get the same range as analog out of digital (Telstra call it Next-G, but it's just 3.5g with a massive boosting system). The solution definately doesn't work, not when techs in the bush call me saying "I used to be able to call anyone from within the server room here, now I can't... *dropout* et *dropout*... *click*".

        It's easy in your story to put blame on the carrier. Not their fault though. If you're going to be flying somewhere and you're not absolutely sure of the coverage (and you're flying in fairly undeveloped areas), you need to get one of two things:

        1) An iridium phone. They're not too expensive compared to other aircraft avionics. They work almost anywhere in the world. And you can get prepaid versions if you don't want a huge monthly fee.

        2) An ELT. http://www.sportys.com/acb/showdetl.cfm?DID=19&Product_ID=7279 [sportys.com]

        This satellite PLB is the smallest, most functional emergency transmitter available. In an emergency, it could quite simply save your life. It transmits on 406 MHz via the COSPAS-SARSAT satellite system with a registered unique, digitally encoded distress signal and 121.5 MHz homing frequency. Plus, onboard GPS acquires LAT/LON when the unit is activated, meaning search and rescue crews will know your location within 100 meters. It is unaffected by terrain, obstructions or weather, and works anywhere in the world. It is also buoyant and totally waterproof. Weighs just 12 oz. and measures 1 3/4"d x 5 3/4"h x 3"w. Powered by two lithium-ion batteries.

        Yes, these two items are expensive. But no more then an annual on your plane or the radio equipment onboard. Blame rests solely on the pilot for the safety of himself and those who he/she carries.

    When my employer (a cell company who shall not be named) killed off our analog system we sent out notices to all analog subscribers over a year in advance.
    And 6 months in advance.
    And each month for the last 3 months.
    2 weeks before shutdown one customer, an alarm company, threatened to sue us to keep it on the air because they hadn't had enough advance warning to get their customers' installations upgraded.

    Apparently they didn't believe we would actually do it.


    And, yes it is worth shutting it down. The power savings alone were significant. Rack space and floor space as well.
    It also freed up a lot of spectrum for re-deployment for high speed data and other stuff that I'm not allowed to talk about yet.

  • If the analog cell services are going off-line in Februrary, it's high time to dismantle the 800MHz band "cell-phone block" for scanning receivers. That was enacted only to create a minimal level of privacy for analog cell phone conversations. When all cell phones are using digital spread spectrum transmissions they all will benefit from spread spectrum's inherent encryption.

    This is in fact not a mandatory analog shutdown, but the date that cellular phone companies are ALLOWED to decomission analog. They're required to keep analog UP until this date, not shut it down at that date. The good word from AT&T is they are shutting analog down as soon as allowed. Verizon, I've heard both that they are shutting it down ASAP and that they aren't (I'm guessing it's up to each Verizon region to decide if they do or not?). I thought US Cellular had specifically said they plan to keep analog up in some areas until at least 2012. And, local providers, they may decide if it's not broke, don't fix it.

              This doesn't negate the point of the article, since many places will lose analog. But, I'm guessing some of these ultra-rural desert and forest type situations, the local provider may keep analog up, at least for a while. Ultimately, though, there's no new equipment available, and indeed I've heard service parts are low too, so it'll have to go once it's unservicable.
    • Ultimately, though, there's no new equipment available, and indeed I've heard service parts are low too, so it'll have to go once it's unservicable.

      True enough but shutting down a lot of sites means a plethora of slightly used replacement parts sitting around...

      So they might be able to keep some stuff going for quite a while.

Instead, I keep an old Nokia TDMA/AMPS phone in my car just in case since it'll still dial 911 and gets better range than any current phone.
