mobile jammer circuit

Bravo, Anonymous Hero! Thank you for upholding what's right. There've been several requests for these things and I've always said no. Unfortunately, some people seem to think that they are not responsible for a possible crime by providing information. This is clearly illegal and quite possibly dangerous. I believe that CR4 should make a stand on this.

Bravo Bravo Bravo Vulcan and Hero.

CR4 - Please listen to them.

Fully agree.

But out of interest, on what basis are governments permitted to operate such devices in locations where they want no communications to occur within certain bandwidths, for example, cell phones in prisons?

Actually, that is the only example I can think of. Outside of miltary, that is, and let's not go there.

Your question, "on what basis are governments permitted to operate such devices in locations where they want no communications to occur within certain bandwidths,"

DUH!

The answer is "GOVERNMENT"

Well, thanks, but even governments are obliged to operate within the law.

So either they must be exempted from compliance in such cases or else the jamming of devices in specified places by the government must be legislated for.

Which means companies must be making the equipment (last time I looked, most governments not in the electronic communications business).

So those companies must also in some way be exempted.

And if the technology to perform such jamming is in the private industry domain, the genie is out of the bottle, is it not?

There are some commercially available Jammer units, sometimes used in restaurants, to stop people using their mobile phones and thereby disturbing the meals of other patrons.....it forces them to go outside. The ranges are relatively short too.....

Whether this is a true form of jamming or not I cannot say, maybe its only the frequencies for mobile phones!!! I do not know, but they are actually called Jammers....

Certainly these units are available in Europe..... I have also seen them demonstrated on several TV shows a few years ago....

A quick check on the web shows that they are still available, for example:-

I find the idea VERY attractive for restaurants, concert halls and Cinemas!!!!

They are illegal in the U.S. and I've read that both the U.K. and E.U. have not approved these devices. I guess that means that they are not illegal in Britain or Europe but aren't allowed either (try to figure that one out).

In any case, if someone jammed my phone without my knowledge, I would be very upset. However, I've taught myself and my family to respect other people when inside a church, restaurant, moviehouse, or other. Either switch it off or put it in silent mode.

I would support these things if they are regulated, meaning, you'll need a license to install these things in a place. They cannot be carried around or transferred from place to place. An establishment that has these devices should have a sign on the door saying that it is using such a device (so I can avoid them ).

You said:- "I've taught myself and my family to respect other people when inside a church, restaurant, movie house, or other. Either switch it off or put it in silent mode."

If only the rest of the world followed your good manners, but of course they don't.

By the way, I have no intention of buying or using one of these units, but I can see the attractive side for certain areas......

We got on well without mobile phones years ago, but today, too many are addicted to its usage.....

I do own two Mobile phones, both are powered on and have current cards, but they do not go everywhere with me!!! They are mainly for my own business use only.

If you pay your license fee for a channel you have the right of protection against jamming by law.

The police does use jammers in the fight against crime (drug trade for example) and I agree with that. Any person engaging in a criminal activity looses the protection afforded by law.

I think in most countries the police needs a warrant to operate a jammer when investigating a crime. They usually have permission to act in emergencies but may have to "please explain" later for abusing the authorisation.

I agree with all the posts above and CR4 should take a stand on these items.

But you have to admit there are people out there that are just stupid enough to not know it's against the law.

Whats really good is that CR4 is full of good and honest people who will not support those activities.

What really bad is that every bad thing you can think of you can find on the web.

From making meth to atomic bombs.

Sickening what people will do to make a buck.

I wouldn't say "stupid" enough to not know... it's more a question of "naive." For the longest time i thought... how can radar detectors (fuzz busters) possibly be legal?

Anyway...Even if they were legal, I think cell phone jammers would be a bad idea anyway. What if there was an emergency and you didn't know where the closest land line was?

Obviously if it's an issue of National Security or anything like that... then yes... jam 'em. If it's just an issue of annoyance... then kick the prick out of the lecture hall, restaurant, movie theater... etc.

saurabhpandey2004,

This issue has been dealt with extensively in a previous post.

Also, before you design a cell phone jammer, it would be in your best interest to see if they are legal in the place that you live. If they're not, you could get yourself in some real trouble.

Hi saurabh,

mail me at rishi_rajpoot@yahoo.co.in i will definately help you in this matter......

See what I mean (post#2) .

There are those who cannot learn and those who refuse to learn.

Neither of which care to listen.

In any case CR4 shoul boot him for providing information that could possibly be used for illegal purposes.

Just my take on the matter tho.
