How Signal blocker Jamming Works
At present, there are two ways to interfere with downlink signals. One is high-power suppression, which is to send out 2\3\4\5G and white noise signals in the same frequency band as the base station signal through a piece of equipment to drown out the original signal, thereby Realize the shielding of the signal. This method will also interfere with the uplink signal of the base station.
The other is the signaling-level intelligent blocking jamming signal technology. The device scans the public network signal through the scanning antenna, and then blocks the public network base station signal through signaling-level instructions, simulating the public network base station signal to transmit false base station signals into the environment. Signals are induced, thereby blocking specific signals. This type of equipment has low power and good shielding effect, which is the development trend of the new generation of mobile phone signal jammers.
