Mobile phone signal jammers work similarly to radio jammers because they emit the same radio frequency as mobile phones. This will cause enough interference so the call cannot be connected to the phone. There are currently two types of cell phone jammers. The first category is usually smaller devices, which prevent signals from being sent from the cell phone tower to each cell phone. The blocking frequency is between 800 MHz and 1900 MHz. Most devices using this technology can block signals within a 30-foot radius. The phones in this area do not show any signal at all.
Now you can politely shut them up and leave, or you can buy a cell phone jammer and leave them alone.
