We're Jammin', Hope You Like Jammin' Too
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."
What? Wouldn't blocking the cell phone signal only prevent the person from sending the picture off? The photograph could still be taken and simply sent later, once the cell phone is away from the jamming signal, right?
Maybe this problem would never have gotten started if people had been responsible with their phones to begin with? But no, and here are the consequences.
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.

While I'm tempted to use this to silence those inconsiderate bastards in the movie theaters, there is a LOT of risk involved. How would you feel if, because of your jamming, someone didn't get an important emergency phone call and got fired / dumped / beaten senseless / etc.? If something were to happen because they didn't get a call, and it was found out that you were jamming the phone, could you be held liable for any proven damages?
Regardless of how rude it is for people to be talking on cell phones anywhere and everywhere, you have no right to decide for yourself, "They shouldn't be talking, so I'll stop them."
If people like you actually turned off your freaking phones in theatres and at school, maybe jammers as described in the article wouldn't need to exist...

If I switch my phone on to silent or vibrate, and divert voice calls to my voicemail there's nothing wrong with me sending or recieving SMS text messages, or browsing WAP should I so wish. Why you'd go to a cinema and then use your phone instead of watching the film I really don't know, and maybe I'm lucky but I've never been bothered by anyone doing so. Mobile phone jamming dosn't stop other sorts of antisocial activity. Kids will still make a lot of noise and throw popcorn at each other, and if a group of drunken idiots decide to make a nuisence of themselves then mobile phone jamming won't help that. There are ushers and managers (and god forbid, maybe your good self) to deal with that sort of thing should they need to. If I can use my phone in the cinema (or anywhere else) without bothering people why can't I? Besides, should there be an emergency I may need that phone.
If people on phones are annoying you, maybe you should tell them.
Then perhaps they shouldn't be in the theater. What kind of monster is it that is expecting some important call about some life threatening situation...and still goes to the theater and insists on ruining the experience for everyone else?
Amazing...how we all got by in life VERY WELL without cell phones. People, they are NOT essentially, they are nothing more than a dispensible luxury item. As such, theaters, restaurants, play houses, and classrooms are not acceptable places to be using them. End of story.
In Bushworld, they struggle to keep church and state separate in Iraq as they increasingly merge the two in America.
As much as i can see the reasoning (pres. safety, remotely controlled bombs, etc...), it still leaves a bad taste of "some are more equal than others" in your mouth. Security (even presidential) & military should abide the law just as anybody else. Change that stupid law, if necessary.
IMHO such a law is not logical anyway: since when does some cell-phone operator "own" the airwaves of e.g. my living room, or more to the point, my restaurant / movie theatre. What exact difference does active / passive jamming make w.r.t the law (if it's on my very own property)? How do they justify the (il)legality of one or the other...
what the position here in Germany is, I dunno... Does anybody else, I'm curious.
Here's another page on the same "cellphone-like" product.
I don't agree with random people able to jam the phone signal. However, it makes sense for certain places, like movie theaters, banks, etc, although they should clearly have a sign saying "Warning: Cellphone signal jamming inside the building" or something.
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.

Sometimes when people on the other end have a lot of background noise I find myself struggling to hear them and myself shouting. It's just instinct, you feel like you have to shout over their noise. When I realise I stop, but I bet the people who are doing it don't even realise.
Does that remotely-switch-off-cellphone-camera-thing also decapitate your regular digital camera? I'd be very surprised (and impressed). Seems like more security snake-oil to me.
A I stated in another reply, I think the FCC should allocate a courtesy zone signal, but not jamming.
Letter To Iran
Doctors? What if the life-threatening situation occurs at the theater, like a heart attack? Jam away but it's only a matter of time before someone gets rightfully sued for blocking communication. I'm surprised the cell carriers aren't doing it already.
Nothing is more annoying that going out to eat and some asshole is hollering on a freaking phone, "CAN YOU HEAR ME NOW?" every 10 seconds as he chats with his pals about absolute nonsense while you are trying to have a quiet dinner.
Not too long ago they had phone booths in restaurants and if you had to talk to someone you went to the phone booth and closed the door.
I do not give a shit, nor do I want to hear other people's conversations. I don't want to hear beepers or cellphones going off.
Why do people have to make so damn much noise? Loud motors, loud stereos, loud machinery, loud computers, loud refrigerators, everyone has to be noisy. And as the noise level goes up, people holler louder to go over it.
When I was a little kid I HATED when my mother used to tell me "Silence is golden".. Now I know how very right she was.
Jamm on baby...
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.

In a restaurant, for example, it's perfectly fine for two people physically in the restaurant to be talking loudly at each other (in fact, in many restaurants everyone's talking loudly at each other), and yet no one would think of wandering over there and telling them to shut up. Conversely, people would be perfectly in their rights to expect two people talking in a movie theater to be quiet once the show starts, and it should be the same with cell phones.
This means that this type of problem would be more easily solved by just having areas where people are expected to be quiet (like theaters) do passive shielding, which is already legal. It's legal, costs cell phone users nothing, and isn't subject to vigilante jamming. Improperly used, both cell phones and phone jammers can become an annoyance.
I will use my psychic mind reading powers to say that you must be atleast 35.
How come every generation of old people feels the need to criticize every new technology that comes around by mis-characterizing it?
I have no interest in being on an electronic leash, forced to be accountable to someone - somewhere
If you put yourself in a situation where you're "on an electronic leash", then that's your fault. Do you realize that you don't have to answer a cell phone whenever it rings? It's pretty nifty technology, you have to press a button to answer it.
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.
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.
I can't think of a better place for them to be than in movie theaters or at the opera houses of the world. Since these companies are apparently trying to figure out how to remotely disable cell phone cameras, perhaps they could somehow remotely force peoples phones into vibrate or something.

Heheh... Nope, but I'm old beyond my years.
How come every generation of old people feels the need to criticize every new technology that comes around by mis-characterizing it?Actually, I love technology; my career choices undoubtedly reflect that.
If you put yourself in a situation where you're "on an electronic leash", then that's your fault. Do you realize that you don't have to answer a cell phone whenever it rings? It's pretty nifty technology, you have to press a button to answer it.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.
Fire and Meat. Yummy.
Not terrible arguments, but I still maintain you're putting yourself in that situation. Tell your wife and friends:
"Look... I don't feel like answering my phone all the time, and I don't always have it on me anyway. Leave a message."
I know when I call someone's cell phone and they don't answer, I assume they don't have it on them or they're in an area where they don't get service.
wtf is the point in jamming phone signals for university students in lectures.
If someone isnt paying attention, or causing any kind of disruption, you kick them out, as i saw several lecturers do in my days as a student.
University students dont have to be in every lecture, they are not forced to sit through it, and its not like theyre school kids and theres some legal obligation to teach them.
If the lecture bores you, or you think nattering on your phone is more important, get the feck out and copy someones notes later.
Blocking mobile phones in order to try and force getting peoples attention is just another example of the growing trend in todays society to look for inappropriate technical solutions to social and discipline problems that have always had an effective old-fashioned solution, if only every one wasnt so lazy and/or afraid of frivolous law suits.
"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."
Or you could, you know, *ask people to turn off their phones* at the start of the lecture/term.
They had grasped this concept when I was at university five years ago, I would be surprised if there were still pockets of the academic world who hadn't figured this out yet.
Most likely these supposed 'sales to universities' are just some marketing crap that the people selling these illegal and antisocial devices have cooked up to try and give themselves an air of legitimacy or acceptability.

If I ever caught a random person jamming my cel phone because they thought cel phones where "annoying", I think I would honestly commit a homicide via severe beating. This anti-celphone crap is really out of control.
I know, some places like quiet nice resteraunts and the movies are not the time or place, but if I'm walking down the street, you have about as much right to tell me to get off the phone as you do to tell me to shut up when I'm talking to the person next to me.
Damn easily-annoyed whinny bastards. Probably the same people who are offended when their ATA drive says "Master/Slave" on the jumpers...
CAn'T CompreHend SARcaSm?
Sure, some cellphone users are inconsiderate, but you don't blame every driver on the road, just the ones who drive recklessly. Also, I find it interesting that you talk about revenge, isn't dropping people conversations a form of revenge for their offending you with their conversations? When you get your jammer, I doubt if you'll politely ask anyone "Do you mind me making the service you pay for and posibly need unavailable", or will you just decide for them.
Just because you were wondering about my reality, my bill tells me that I use about 150/minutes a month, I'd say 20% are work related, and 60% my wife, and the other 20% my family. I am not a "heavy cellphone user", but I need to be sure that the phone is on. When my phone vibrates (I always keep it on vibrate and in my pocket), and I am in a public place, I answer it with a short low "hello", then either "I'm sorry I can't talk right now" or "hold on", but then again I am generally very civil. Maybe that is how you act, but I seem to think of you as less civil.
A definition of self-rightous is someone who would do an illegal act just because they think they are right. Not paying attention to the road (cellphone, radio, sex) is often called reckless driving, and as others have pointed out jamming transmitions of radio is also illegal. Both of those are wrong.
The grass is only greener, if you don't take care of your own lawn.
The problem many people are having isn't that cell phones are fundamentally, the problem is that there are idiots using cell phones. 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.
