Signal jamming is the deliberate broadcasting of radio waves to disrupt or block communication, navigation, or surveillance systems by overwhelming their intended signals, making them unusable for their receivers.
Jamming can target a wide range of systems, including GPS, cellular networks (2G/3G/4G/5G), Wi-Fi, satellite communications, radio frequencies used by drones, and radar systems.
Generally, the use of signal jamming devices by civilians is illegal in most countries, including the US, UK, and EU. This is primarily due to the potential to interfere with critical emergency services and licensed communications.
Jamming is primarily used in military electronic warfare to disrupt enemy communications, radar, and navigation. It can also be employed for security purposes (e.g., preventing remote detonations) or to enforce restricted communication zones.
