Why use the cell phone signal jammer? Is it good?

Cell phone jammers in everyday life may seem like a pretty good idea: Who wants to sit next to someone on the train who’s yammering away to their doctor about the gross details of their last bowel movement? Wouldn’t you get more work done in the library or at your job if you stopped texting your best friend every two minutes? But when you stop and think about it, using a cell phone jammer is a dangerous idea.

I know, some of you are reading this and saying, “No way! I can stop texting and talking while driving, I don’t want anyone knocking out my cell phone.” Like anyone else, I hate to lose my ability to communicate, but the idea is not a crazy one. A company in Doylestown, Pennsylvania called Perfectjammer patented technology in its cell phone jamming device. The cell phone blocker jams the cell phone signal of the person sitting in the driver seat a car going over 10 miles per hour. In other words, the drivers cell phone does not get a signal.

Federal government wants drivers to stop using, looking, and typing on their handheld devices or cell phones. On the other, the government is against a simple solution to guaranteeing people stay off their phones while behind the wheel. At the heart of the opposition to jamming is a concern that it takes away a drivers freedom to call or contact others while they are driving. Actually, if you run your phone through your car, you’d still have that freedom. And since putting the cell phone GPS jammer or some other jamming device in a car would be voluntary, those who still want to have access to their phone would not be impacted.

A signal is transmitted to prevent the handset receiving its base station signal. All phones and Sim cards within the jammer’s reach will be blocked, including those belonging to prison staff. The method is cheap and mostly effective. Interference caused outside the prison can, with care, be avoided, but this may add to the cost.

Cellular access control is a technology born of necessity. Around 2006, Mississippi correctional authorities found they were fielding more citizen complaints of harassment from prisoners using cell phones. Efforts to block the contraband phones were increased, but were not completely successful. “There was talk of going to the FCC to allow signal jammer, but that never got off the ground,” said Smith.

The specter of a bill that would allow jamming of cell signals frightened the cellular industry. In 2009 CTIA, the wireless communications industry association, approached Tecore about developing an alternative to jamming, which became iNAC.

GSM jammers, also known as cellular jammers or mobile phone jammers, are designed to prevent cellular communication in designated areas. The cellular jammers emit RF jamming interference signals that attack the abilities of a mobile phone to receive service from a cellular network. That means that if a cell phone user is beginning to make a call or is already engaged in a call, cell phone jamming will overpower the carrier signal and terminate the call.
