What is a signal jammer?

A signal jammer is an electronic device that transmits a signal at the same frequency as wireless communications, effectively blocking or "jamming" that signal. Jammers work by emitting a signal at the same frequency as the target device but with a higher power, disrupting the communication link by either drowning out the original signal or interfering with the receiving device. Signal jammers can be categorized by the frequency they block, such as cell phone jammers, GPS jammers, Wi-Fi jammers, radio frequency jammers, and drone jammers. These devices are often used strategically by military and law enforcement agencies to ensure secure communications within a specific area.
