How does a jammer work? What are the main principles?

Hi, Bob. There is no secret in how those gadgets work. Frequency blocker simply emits signals on the same frequency you want to jam. Those signals interfere with the signals that transmit the data from and to your wireless device. The field of interference, created in the result simply blocks all of the incoming and out coming signals. So the point is that that GSM signal jammer emits waves in 850/1900 MHz frequencies band, Wi-Fi jammer operates with 2.4 GHz frequency. The simplest jammer consists of: voltage controlled oscillator, tuning circuit, RF amplification unit and a transmitting antenna. Of course you’ll also need a body frame and adequate power source. You can read more about the construction and schematics of a signal blocker on our blog. The main part of it is a voltage controlled oscillator. It creates the wave of necessary frequency, tuning circuit lets you adjust the needed frequency, RF amplification unit simply amplifies the signal power and antenna transmits it. Pretty easy, isn’t it? Signal blockers can be portable or stationary, low range and wide range. The whole variety of signal jamming devices you may find at Jammer-Store! Thanks for your question, I hope I’ve helped!
