Signal jamming is the intentional disruption of communication signals, often used to interfere with radio, television, or mobile phone transmissions. This technique can block or distort signals, making it difficult for devices to communicate effectively. Jamming can be employed for various reasons, including military operations, privacy concerns, or to prevent unauthorized access to information. The technology behind signal jamming typically involves transmitting radio frequency signals that overpower the original communication signals. Devices used for this purpose are known as jammers. While signal jamming can be useful in certain contexts, it is often illegal in many countries due to its potential to disrupt emergency services and legitimate communications.
