So once upon a time, I was stumbling around ebay and saw either a jammer or plans to build one. The idea sounded cool - a little device you could turn on at the movies and prevent assholes from spoiling the experience. A little more digging found them to be illegal. In fact, most countries have outlawed them. There are safety concerns that they'd interfere with pacemakers, and, because they broadcast radio waves, they're subject to FCC laws in the US to some degree, so are on a level with pirate radio. I wonder if there are unspoken reasons for the bannings and harsh penalties, like interfering with official communications of police and fire, etc.

Anyone have any experience with these things? Documented cases of someone being hurt because of one being used? Or someone caught using one?

The subject fasicnates me.

I don't know how they ,"the man", would find out you were using one. I guess if someone died or the signal went out too, too far and messed with police/fire boradcasts it would get suspicious. :dunno:

I dunno if it is worth fritzing out a guy's pacemaker just so I can watch a movie in peace...

Yeah, but you know as soon as a cell phone got jammed, the person violating the movie code would just stand up be make noise some other way.

Plus, you know, no one in the theater could dial 9-1-1 to save the guy, either. You'd have to wait until a theater employee arrived on the scene and then made his way back to a land line somewhere to call an ambulance...

Is Jam illegal? Is that why you call it Jelly over there?

it's not illegal. but it can be banned if it's too sticky.

I assumed these already existed. According to CSI some movie theaters already have these. Are you telling me CSI made something up? What's the world coming to when you can't trust CSI for scientific fact. :cry:

I would never use one, but then again I dont get as pissed off when people's cell phone's go off, it annoys me, but not to the point I would try and do something about it, guess I am too laid back.

I've been thinking about buying one.
There are plenty of companies that sell them and ship them to the US.

The reality is that if you want a small battery bowered jammer, the range is only about a 25' radius. The cool thing is that they actually look like cell phones so you can use it without anybody noticing.

In order to get greater range, you need to go up in size - usually having them plugged into an electric outlet.

Here is the one I want:

If I found out someone was jamming my cell phone, I would give them an entirely new definition of using their little device for jamming.

For me it comes down to how the person reacts after the cell phone goes off. If it just goes off and they shut down the phone, chances are they're embarrassed enough as it is so I'm cool with it.

It's when they actually answer it and start having a full conversation. That's when I get pissed. In my life this only happened once, and the motherfucker was extremely loud and obnoxious about it. NOBODY could hear the movie over this fucking asshole.

Somebody, not me, threw a full slushy at the motherfucker and the guy was covered in blue liquid. The whole crowd cheered and the asshole left and didn't come back.

My wife is a teacher and she is constantly having problems with kids using their cell phones in class. They are constantly texting one another in a pretty amazingly covert way. Having a jammer could help eliminate this distraction and force the kids to pay more attention to their work.

I think theaters are a reasonable place to have a jammer.

And after too many near automobile accidents with people paying more attention to their phone than their driving, I'd love to have one in the car. Set up a 50' radius around my car that is cell phone free. The good thing about this is that all the other driver would have to do to get their phone working again is move away from my car - thus making everything safer. The problem would be that if they lose their signal, the other drivers may focus more on their phones.

At lori's school, if they get caught using the phones in class, they lose them for a week and the parents have to pick them up personally and pay a $15 fee.

The 50 foot cell phone range in a car is a cool concept.

It's highly unlikely that it would interfere with a pacemaker enough to cause death. It certainly wouldn't generate as much noise as a microwave....and you don't need it (or want it) to broadcast continually. You use it in bursts just to interfere with the signal enough so they can't/won't take a call. This allows for a smaller power source and therefore a smaller form factor.

IMO- the real reason this is illegal is $$$

licensees pay big bucks to the government, they wouldn't be happy if anyone who wanted to could just jam a signal at whim...not to mention municipal services interference

eh. the regulations against blocking signals are pre-cell explosion, and there are plenty of valid reasons for it. They should allow exceptions for places like movie theaters, as long as it's well publicized that the signals will be blocked.

In theory I like the concept of this.

However, I have my cell phone on (VIBRATE mode only, which makes no noise) in case the babysitter calls. In which case, I send the call to voicemail, step outside, and call back. In this situation I wouldn't want my call jammed.

But people who answer their phones in the theater are jerkstores.

I look forward to the pre-movie video of a group of cartoon frogs singing Bob Marley's "Jamming."

Jamming someone's cell phone is a good way to get yourself sued if something happens and they can't contact help.

Absolutely.

...and it's a FEDERAL issue rather than local.

Why wouldn't you turn the jammer off if "something" happens and call for help yourself? What would happen in a movie theater that people would need to call for help rather than leave? Are there a lot of hostage situations in movie theaters?

no. but if the parents did the right thing and got a babysitter before going to the movie, if something happened to the kid and they couldn't get a call there would probably be hell to pay.

Yep, and as much as it sucks that people's phone go off in movie theaters, sometimes you just gotta let it roll off your back. Quite frankly, jamming someone's phone signal hurts all the wrong people, chances are the a-hole that leaves his phone on, or worse, talks, will not need his phone while in that theater, but if someone DID need to recieve or make a call, they would be screwed.

I think a lot of the "what ifs" being thrown around in the thread are based on the idea of having it on you and continuously broadcasting. While carrying the item shouldn't be an issue, as possession in itself may not be a crime. Having one that is continually broadcasting is just not feasible on a number of levels.

There is just no way anyone would know someone had a jammer if they didn't have a cell signal. They would assume they can't get a signal and either stop trying to call/answer or go out into the lobby. Assuming we're still using the movie theater premise.

Not to mention that the idea that you have a cell signal available to you at all times is just not real.

People wouldn't piss on me if I was on fire, so whether I had a jammer or not would be irrelevant.
