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.
