Why use and how work mobile phone jammers

Work cell phone jammers

Cell phone signal jammer work in a similar way to radio jammers by sending out the same radio frequencies that cell phones operate on. Doing so creates enough interference so that a call can not connect with a cell phone. There are two types of cell phone jammers currently available. The first type are usually smaller devices that block the signals coming from cell phone towers to individual cell phones. The frequency blocked is somewhere between 800MHz and 1900MHz. Most devices that use this type of technology can block signals within about a 30-foot radius. Cell phones within this range simply show no signal.

Now, you could just politely ask them to shut up and go away, or instead you could buy cell phone jammer and shut them up all by yourself.

Sadly, they keep gaining momentum, as lots of people (particularly prison wardens) would like to believe that a new tech gadget can solve their problems. Not only have a bunch of prison wardens filed a Petition for Rulemaking at the FCC, but they are backing a bill that would require the FCC to authorize cell phone jamming in prison.

In four Monterrey churches, Israeli-made cell phone jammers the size of paperbacks have been tucked unobtrusively among paintings of the Madonna and statues of the saints.

Japan allows public places such as theaters and concert halls to install jammers, provided they obtain a government-issued license. And last week, France’s industry minister approved a decision to let cinemas, concert halls and theaters install them – as long as provisions are in place so emergency calls can still be made.

Tokyo-based Medic Inc. sold thousands of its Wave Wall gsm jammer before the government stepped in and regulated their use to venues with live performances.

Margarita Escobedo, a Catholic who goes to church at least twice a week and volunteers at the San Genaro church, says she would welcome the jammers in her parish, where cell phones are becoming a nuisance.

GPS jammers are usually small devices that plug into a vehicle’s lighter port and emit radio signals that overpower or drown out much weaker signals such as GPS or others.
