Are You Annoyed by Abuse of Cell Phones?

What can a cell phone signal blocker do?

Since so many people have been annoyed and inconvenienced by the ubiquitous abuse of cell phones, new innovation would lead to simple solutions, and in many other countries, the solution is the portable cell phone signal blocker . The cell phone signal blocker sends out a blanket of noise in the same frequency range as the cell phone, and by raising the noise floor, makes it impossible for the phone to stay connected. The cell phone user doesn't know the cause of the interruption, in most cases, and just puts off the conversation until later.

Where and why do people use a cell phone signal blocker?

In various countries, museums and restaurants use full-time cell phone signal blocker, because, as many people around just won't cooperate and turn their phones off. Jamming is only permitted in countries where the overall benefit to society is more important than some individual's hurt feelings. So, the use of a cell phone signal blocker may be illegal, yet there are those who are so irritated by mobile phone addicts that they don't mind taking the risk of operating outside the law for a few seconds at a time in order to cut off someone else's conversation, especially when that conversation seems to go on and on, and seems to get louder and more frivolous with every passing minute. The science of jamming a cell phone are actually quite simple. Mobile phones operate by sending signals along a range of the electromagnetic spectrum reserved for their use. All a cell phone signal blocker needs to do is broadcast a signal on those same frequencies, and it will interfere with any devices trying to transmit in that range. The phone's screen will simply indicate that no signal is available. A pair of US inventors are bringing to market a computerized car key that prevents people from chatting on mobile telephones or sending text messages while driving. This Key2SafeDriving adds to a trend of using technology to thwart speeding, drunken driving, and other risky behavior proven to ramp-up the odds of crashing.

A New Cell Phone Jammer: CJAM-CPC

CJAM-CPC is a cell phone jammer to CA Wireless' suite of solutions for controlling the use of illegal or unauthorized cells phones. Based on a cellular testing system, the CJAM-CPC can control and eliminate the illegal use of cell phones by inmates in prisons, criminals during the committing of a crime, or ensuring complete cell phone security within a building. This system can be used for both CDMA and GSM communication, providing both hardware and software interfaces making the CJAM-CPC user friendly.

Designed by cellular engineers, the CJAM-CPC solution monitors and interacts with cell phones by way of RF receivers and RF signal generators for both the Reverse and Forward channels. Using an integrated GPS receiver the CJAM-CPC is capable of precisely timed firing of signals and precise synchronization with the GSM and CDMA networks under test.

The CJAM-CPC can be deployed in its own chassis with connectivity through it's built in Ethernet port. The standalone version of CJAM-CPC provides complete portability allowing the system to be deployed as needed. The self contained model has the keyboard, screen and Ethernet interface built in.






As part of CJAM's Distributed Antenna System (DAS) the coverage area of the system increases to almost any size building. Using the CellAntenna's MOFORSAS, the Multiple Output Fibre Optic Smart Antenna System, and CJAM-CPC can be centrally located covering multiple buildings in a campus. The CJAM -CPC can be used as well in conjunction with CJAM-DT (cellular location system) and CJAM-NF (cellular jamming system) to provide a full solution for cell phone security issues all within a single DAS deployment.

Uses for the CJAM-CPC include:

- Correctional facility control of contraband cell phones by inmates

- Police SWAT teams for controlling communication during raids or hostage situations

- Secure Government buildings including Embassies, and other sensitive high security areas.

- Police Bomb squads used to prevent detonation of bombs.

- Universities for securing examination areas.

- Corporations requiring secure environments free from cell phone security leaks

- Border Patrol reconnaissance

- First Responders to locate / communicate instantly with people underground or trapped due to building collapses or bombs

Cell Phone GPS Jammer: for or Oppose

Every coin has two sides. People around the world have different opinions about cell phone GPS jammer. It’s legal in this country while illegal in another. What do you think of this kind of thing? For or oppose?

Here are some opinions from others:

A: It would be easy to be oblivious to an emergency in an area that size which could encompass hundreds of people (especially a self-absorbed ass who would use something like this). Even assuming you were completely aware of everything going on in your vicinity, I doubt you could sense important incoming calls. I'm sure the gentleman dining at the table next to you won't mind not receiving the call that the hospital finally has a transplant for him. I'm sure the mom sitting three rows behind you at the theater won't mind missing the call from the babysitter that little Timmy swallowed poison.

B: People will die without mobile phones? This didn't seem to be a concern 20 years ago; landlines still exist, so find one. By law in the US business owners can't block mobile phones in their store unless the building was constructed out of resistant material before hand.
It wouldn't be a problem if people used common courtesy on both ends. Eventually this will be solved with the advent of having mobile phones implanted internally.

C: I would only advise using a jammer in places where cellular telephone usage is highly annoying and socially unacceptable.. i.e. a resturant, movie theatre, classroom, etc. Maybe when some retard on the road isn't paying attention because of his conversation too.
Otherwise, I think it would be best to leave people alone. However, in these situations, it is rather difficult to get caught or for the FCC to do anything about it. If you're running it 24/7 out of your apartment and telling everyone about it, then you do deserve to get caught and it would be much easier to find the source of the interference to implicate you criminally.
Everyone loves to huff and puff indignatly on the Internet. The FCC can't do anything more than try to question you (and you can refuse to talk to them) and try to take signal readings outside your residence.

D: The fact is, cell phone jammer really SAVED alot more live then cellphone ever did... How do you think they prevent remote detonation of bombs? Jammer... You guys clearly aren't cops.
You'll be hard pressed to find any US vehicle in iraq not equipped with one, it's the solution to IED, what do you think soldier do to place a cell call? They just MOVE AWAY from the vehicle ( or turn them off, but that rarely happens ). That's all... The exact same thing you do when you get a low signal, you move to find a better one. You see an emergency ( and of course you don't offer to help! hell you're the all important cell guy who's gonna save the day! ), you move a couple of feet and you get your signal back.
Should we blow up moutains because they block signals?

E: great place to use them is where cell phones are not allowed, like at MANY schools, kids use cell phones to cheat on tests. Too bad those select few of cheaters and other inconsiderate people have to ruin cell phones for the rest of us. I have no beef against cell phones, only how they have become (to some people) a necessity for social life. Last time i checked, you did't need to talk to a friend who is cutting school, while your taking a test.

So, how do you think of this problem?

GPS Jammers Provide Convenience to Car Thieves

People always respect that tech is used to fight crime, but the opposite is that the bad guys only to get better gears. The sole crime-fighter who manages to always have the better gadgets is Batman. Now car thieves are using cell phone gps jammer to jam the satellite signals so that some antitheft services used to locate stolen automobiles are cease to be effective.

It’s not hard to do, either. A quick Google Shopping search for GPS blockers shows models on sale for under $30. They don’t even need to be powerful. In order to swamp the incoming satellite signals, a jammer only needs to put out two watts of power. Speaking at a symposium, Bob Cockshott of “cybersecurity” company Digital Systems KTN said that “the strength of a GPS signal is about as strong as viewing a 25-watt light bulb from a satellite 10,000 miles away.”

It’s not just criminals who are using this tech, either. Employees whose cars are tracked by their companies use them to go off the clock, and according to The Guardian, German truck drivers use them to “to evade GPS-based road charging.”

But knocking off gas-guzzling cars and sticking it to the man are just the annoying part of the potential for GPS jammers. A 20-watt unit would be enough to cover a commercial airport, with rather scary results.

There is also the possibility of feeding false signals to a GPS unit, which would be harder for an operator to spot than straight-up jamming. If you start doing that to boats driven by sailors with no sextant experience, you get havoc.

Still, something good could come of this. It’s possible that people read the story could become not as much as they trust their in-car sat-nav units and actually look through the windshield once in a while. This would reduce the possibility of the estimated 300,000 crashes caused in Britain every year by people who over trust their GPS.
