Signal jammer modules are sophisticated electronic devices designed to block or disrupt wireless signals in a specific range. Usually, it is used to protect privacy or for military use. It works by sending powerful radio frequencies across a certain frequency band. This interferes with and overpowers the original signal. The disruption of signals can be used to prevent unauthorised communication, safeguard sensitive data, and disable remotely controlled explosive devices. The signal jammer module is available in a variety of sizes and powers, which allows for varied applications. They usually come with antennas that maximize the range of signals.
