With so many people using cell phones these days, one of the devices that have popped- up on the market are cell phone jammers. Be advised that cell phone jammers are usually black market devices, since using them is illegal in most municipalities.
However, for those that are tired of hearing endless cell phone conversations or constantly being interrupted by incessant cell phone ring tones, a cell phone jammer seems like the perfect device to own.
How Cell Phone Jammers Work
Cell phone jammers 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.
The second type of cell phone jammer is usually much larger in size and more powerful. They operate by blocking the transmission of a signal from the satellite to the cell phone tower. Some powerful models can block cell phone transmissions within a 5 mile radius. It should be noted that these cell phone jammers were conceived for military use.
Once again, it should be noted that operating or even owning a cell phone jammer is illegal in most municipalities and specifically so in the United States. Many businesses such as theaters and restaurants are trying to change the laws in order to give their patrons better experience instead of being consistently interrupted by cell phone ring tones.
