We're Jammin', Hope You Like Jammin' Too 422

Posted by CowboyNeal from the peace-and-quiet-devices dept.
theodp writes "Slate ponders whether a climate where anything can be photographed or surreptitiously recorded means the once-esoteric world of cell-phone jamming will become mainstream. Sites now offer portable cell-phone jammers that can provide you with the same kind of security bubbles used to thwart industrial spies, hostage-takers and bomb detonators. While actively jamming a cell-phone signal is illegal in the US, a distributor reports most of his sales go to US customers, including universities which use the technology to stop students from diddling away on phones during lectures."

        If you read the fine print (which actually isn't on the product page [icebergsystems.co.uk] as far as I could tell, they say that you have to have an "approved phone". From The Register [theregister.co.uk]:
        The snag is that Safe Haven technology needs to be integrated at the time of manufacture into new devices or installed as a Java download update to suitable equipment already in the market.

        "You need to have an approved camera," Blagden admitted, adding that the incorporation of Sade Haven technology is unlikely to affect handset prices.

        In other words, like most DRM-type schemes, it only works if your camera "supports" this feature. And just like DRM, I don't think it's going to be very popular among consumers -- this is a "feature" that benefits the guy trying to stop the camera user, not the guy buying and paying for the phone. I'd especially think that industrial spies would be smart enough to get a phone that didn't support this.

      This is true. But I don't think that's the primary application of cellphone jammers.

      Yeah, well, Beethoven's Fifth, being played through a crappy 2" piezoelectric disk speaker as the ringtone on some Nokia in a movie theater. That's the best reason for jamming that I can come up with. (Why custom ring tones? Don't people know those things sound as stupid as coffee can mufflers on Honda Civics?)

      I have had cellphones with work, and was glad to get rid of them when I did. I have no interest in being on an electronic leash, forced to be accountable to someone - somewhere. Or standing in the line-up at Wal*Mart, the ring and promptly following, "Hey, it's me. Whatcha doing? Wanna come over?" (Who is "me"? If I slept with this person, it must not have been very memorable.)

      In short, I *hate* cellphones.

      Quoting from article: including universities which use the technology to stop students from diddling away on phones during lectures.

      Hey, if the student diddles quietly, it's his funeral when his GPA drops and he gets kicked out of school.

      Cellphones with integrated digital cameras might have their place, though. I know a university student whose math professor puts excellent and comprehensive notes on the blackboard. So he started to bring a digital camera and a small tripod to class, and takes pictures of each blackboard full of material. He sent me a sample a while ago. [glowingplate.com] An integrated camera/phone would never run out of available internal memory. Personally, copying the notes down would help me remember the material, but whatever works for him... there's a certain style of practical problem solving skill at work there: he's a second-year engineering student; I think I'll have to hire him when he's done. :)

          I know. But the reality is that when the phone rings, you feel obliged to answer it. Then, pretty soon, it's a nuisance and makes you feel guilty.

          Of course, you can turn off the ringer. Then, the problem becomes, "Huh-NEEEEEEE... Why didn't you answer the phone when I called? What were you doing?"

          People become accustomed to being able to reach you and talk to you about every stupid little thing that happens in their lives.

          For the very same reason I eschew land-line telephones or ICQ and other messaging systems, and like e-mail: It's a constant interruption. With e-mail, on the other hand, the sender can send the message when it's convenient for them. I can then read it and reply when it's convenient for me. Telephones, in particular cellphones, require it to be convenient for both parties to talk at the same time.

          If you say that the advantages of having a cell phone aren't worth it for you, that's fine. But the only real disadvantage is how much it costs and having to carry it in your pocket. The whole leash thing simply tells me something about your relationship with the would-be leash-holder.

          Okay. Try this. Turn off your cellphone for a week. Tell me what you get from your friends. "I tried to call you, but you didn't answer." Endlessly. You've built up the expectation that you will be available to discuss all sorts of stupid things, including the weather, any time they're feeling bored in the lineup at the grocery store.

          My friends know how I feel about cellphones, and telephones in general. We communicate by e-mail. We arrange to get together to drink beer by e-mail.

          I imagine some older folks didn't like the telephone when it came out - I refuse to be on a leash when I'm at home, forced to be accountable to someone - somewhere.

          For sure. But there's still the escape with a regular telephone. If you don't answer your land line, they assume that you're out. If you don't answer your cellphone - which, by tradition, is always with you - then they assume that you're ignoring them.

        Well that's not exactly a great idea, now you would be transmitting a signal, just like a cell phone, as well. And the other persons phone will still try to keep in contact with the tower, so it will transmit periodically, so now you have two devices transmitting RF radiation near the medical equipment. Jamming is like screaming in someone's ear in order to keep them from hearing someone else talk.

    preventing diddling on phones during lectures, and cheating during exams I think are perfectly fine uses of cell-phone jammers and should be illegal. I also think all variety of theatres should employ this technology so the asshole who doesn't turn his phone off wont distract/annoy the entire audience when his annoying ring tone blares out 10 times. And rather than turn his phone off he pretends it wasn't him.

    Of course, this can also be used for evil. Big evil. If I had a portable jammer I could bring it to a bank and prevent everyone from calling 911 as I robbed it. I think that's why these things are illegal.

    If a criminal is attacking you right now a cell phone is mostly useful as a second-rate bludgeon. Or maybe, with phones getting so small these days, you could get him to swallow it and use it as a tracking device :-/

    But being able to call emergency services can be very important in the phases leading up to an attack. It can also be helpful for witnesses who can't get physically involved to summon the police or ambulance. This changes all that.

    I see it as most frightening in cases where the attacker has a lot personally invested in the crime. The abusive ex. The stalker. The dangerously obsessed. In those cases, where the defender needs every available resource, the sudden disappearance of an important tool can be a matter of life and death. We've already seen stalkers use GPS transponders to track their ex girlfriends' cars. So there are at least a few geeks gone bad out there.

    I'm afraid I don't have any solutions. These things are already illegal to use. Any thoughts on what a prospective victim or the authorities can do? And yes, I've already factored in "Have a gun." It's not an option for everyone. It is only part of the soluation when it is.

    Cellphone jammers are a bad idea on several levels. I'm just waiting to see the news story about someone who has a heart attack or epileptic seizure hit, and that the victim died because someone tried to use their cellphone to call for help, but said phone was within range of a jamming device.

    I suspect it would be reported that the few extra seconds (or minutes) taken for the caller to get out of range of said device, and call for help, could have made all the difference in the world.

    Take that another way: What if someone's within range of one of these things, and someone tries to call them to let them know that their wife or roomie or whoever has been critically injured, or fallen seriously ill? Seems to me that whoever's operating the jammer under such conditions could be in for some serious litigation.

    Another example. Lots of firefighters and paramedics are beginning to depend on cellphones for much of their communications. I can only imagine the consequences if someone in the area is operating a jammer.

    I know others have posted that they'd like to jam something "just within ten feet" of themselves, but -- news flash! -- a jamming signal, by its very nature, cannot be limited in this way. In the world of RF, when you radiate a signal, it's going to radiate all over the place. The only way you can control where it goes is to put a Faraday cage (read: shielded enclosure) around the area you want to irradiate (and I think people would look mighty silly walking around in copper-mesh suits, with their 'tail' of a grounding wire).

    In other words: Any signal powerful enough to overcome a cellphone's normal exchange with a nearby cell site is going to have to be powerful enough to radiate a lot further than ten feet, period.

    A REAL solution to the problem would be (guess what?) education and attitude adjustment. Get people to the point where turning their phones OFF (or at least putting them into 'Silent Ring' mode) is a reflex action for restaurants, movie theaters, etc. Start such teaching early ("Responsible Cellphone Use 101" anyone?), perhaps including it as part of common courtesy and manners, and it'll be something that's useful for life.

    Cellphone users really need a strong reminder that their world is not going to collapse if they don't catch every call the millisecond it comes in. At the rate we're going, I won't be surprised to learn that "cellphone addiction" becomes a very real medical or psychological disorder in times to come.

However, my phone is private property, and no one may interfere with it within the physical boundaries of its case. They can jam the waves from my antenna in their air, but they can't send "off" commands inside the phone. So they might claim some kind of "performance" rights, and perhaps copyrights, on the appearance of objects inside, but they can't materially prevent me from snapping a picture and taking it outside, without violating my property rights.

    Jamming is a solution, but simply being able to locate and reprimand people with cell phones would probably be better in the long run.

    First of all, it's a sociological solution. If people know they can be detected, they would simply concentrate on following the "no cellphone" rule, rather than trying to be discreet or circumventing jamming mechanism (which would lead to a jamming/anti-jamming escalation).

    The detector wouldn't have to be so complex (though it would certainly be tres cool to have a tricorder-like 3D spectrum analyzer). It could be as simple as a wand hooked up to an amplified speaker :P . With a little more work, you could probably tune them to the 2Ghz cell phone frequencies to increase their range and do some triangulation to cover a larger room, and put it on a public display so everyone could see who was violating the no cell phone rule, or forgot to turn them off, etc.

But those same idiots drive recklesses, double-park, run cars without mufflers at 4 in morning, and engage in a host of other socially unacceptable activities. Would you ban cars because some people are idiots?

    Specific silly objections:

    But people use it in restaurants, and that's rude.. How is it rude? Many people specifically go to restaurants to talk with other people. Is taking to someone remotely fundamentally worse? If they're being too loud you do what you would do if someone was being loud talking to the companion: ask them to quiet down. Now, if you're dining with someone and that someone proceeds to take a call while you sit there, that's rude. But it's only rude to you. The answer isn't to disable the cell phone, the answer is to dine with non-rude people.

    People use it movie theatres, and that's rude. Indeed it is. And the occasional gaggles of high school kids behind me laughing at the serious drama are also being rude. The answer? Tell them to shut up. Point out that if they want to continue their conversation they can do so from the lobby.

    People use it in public, and that's rude. That's just surreal. Would you be complaining if their friend was instead standing right next to them talking? It's a public space, people talk, learn to live with it.

    If you have a cell phone you're on a leash and always have to answer it. That's just a silly habit; break it. Get a phone with silent alertand leave it in vibrate mode all of the time. If you don't want to take a call now, just ignore it (on many phones you can hit hang-up and immediately shunt them to voice mail). If it might be important check the caller idea. Not important? Ignore it. Most cell phone plans come with free voice mail. Use it. If you have someone who gets pissy when you don't answer, politely explain that would rather not be on a leash to them. If they still insist you should answer they're rude, get more polite friends. (If it's your boss, get a new cell phone number and don't admit to your boss that you have it. I see no reason for my boss to have my cell phone number. If your boss is paying for the phone... well... high availability is probably what he's paying you for.)

    There are plenty of good uses for cell phones, even in movie theatres. A friend of mine is a sysadmin and is on call every few weekends. He could simply sit at home all weekend, or he could take the chance that he might get a call while he's at a movie. If no call arrives, he enjoys the movie. If a call arrives it's unfortunate, but he knew the risk. He's very polite, when his work phone rings he immediately leaves the theatre to answer it.

    Ultimately cell phone jammers are a crude solution that harms good users of cell phones as much as rude users. The answer is to educate and mock stupid users until they get the picture.
