What is a jammer and how does it work?

To put it simply, a Jammer is, fundamentally, a signal blocking device, which transmits synchronized radio waves on the same frequency range of the device that one needs to blur, therefore preventing devices from transmitting data in the chosen area. But, before purchasing such devices, you should consider a few important factors:

What is DRFM jamming?

Digital frequency radio memory, or DRFM, is a repeater technique that confuses a radar by altering and re-transmitting received radar energy. For example, by changing the delay in transmission of pulses, the jammer can alter the range the radar detects and creating false targets.

How do radar jammers work?

For example, jammers radiate interfering signals toward an opponent’s radar, blocking the receiver with highly concentrated energy signals. The two main jamming techniques are noise techniques and repeater techniques.

How do radio jamming devices work?

In the United States, radio jamming devices (known as "jammers") are illegal and their use can result in large fines. In some cases jammers work by the transmission of radio signals that disrupt communications by decreasing the signal-to-noise ratio. The concept can be used in wireless data networks to disrupt information flow.
