Signal jammers support infrastructure assets critical to the functioning of nations and regions international banking, power grids, transport and communication systems,Therefore, its reliability and accuracy are critical. Military jammers have increased productivity around the world and fundamentally changed military operations. The use of different types of military signal jammer by terrorists and states is becoming more common.
A Brief History of Military Radio Jammers
The discovery and use of radio waves as a form of communication dates back to the late 19th century. The first recorded intentional radio interference (interestingly, for commercial rather than military gain) was during a yacht race in the United States in 1901. During World War I, radio was primarily used for military and maritime communications, but became increasingly used for propaganda purposes. It wasn't until the 1920s that radio was able to bring mass media to millions of listeners.
During the wars and two world wars of the 20th century, radio transmissions enabled governments and movements to transmit prohibited information and ideas across national borders. Government and military efforts to disrupt these transmissions have evolved over time, overcoming technical, financial, and geographic barriers. During the Cold War, for example, the communist regime in Poland conducted a 39-year ruthless jamming of Radio Free Europe transmissions, placing transmitters at police stations and military bases. This attempt replicated other interference campaigns by other communist regimes and colonial Western powers. Jamming, although limited in range and effective only on certain frequencies, controls a significant portion of the flow of information for political and military reasons. To this day, radio broadcasts for propaganda purposes and interference continue in the contested territory.
