Cell Phone Jammers: A Convenience or a crime?



A cell phone jammer is a small device that looks like a walkie-talkie. It is used to prevent cell phones from receiving signals from base stations.

Cell phone jammers block cell phone operations by sending radio waves along the same frequencies that cellular phones use. The radio waves cause interference between the cell phone and its ability to communicate with cell phone towers.

Cell phone jammers come in a variety of sizes, can affect large or small radiuses, and can target a variety of cell phone bands (frequencies used to communicate with towers).

Jammers either disrupt phone-to-tower frequencies or tower-to-phone frequencies. The latter is typically more effective.

Cell phone jammers are illegal according to FCC regulations. The reason is because cell phone jammers could prohibit emergency vehicles from communicating with each other.

It can also disrupt police communication and jammers may prohibit someone from reaching emergency services if they're used incorrectly.
