The working principle of the wifi jammer is that within a certain frequency range, the mobile phone and the router are connected by radio waves to complete the transmission of data and sound with a certain baud rate and modulation method. So what are the characteristics of the wifi signal jammer? The wifi jammer device only shields the mobile phone signal in the test room, does not interfere with the mobile phone outside the test room, and will not interfere with the base station, only blocks the mobile phone signal, and does not affect the normal operation of other electronic equipment, only shields The downlink frequency of the transmitting base station does not affect the uplink frequency. Jammer mart wifi frequency jammer is easy to operate, install the antenna correctly, and it can run automatically after connecting to the power supply. It is green and environmentally friendly, the electromagnetic field strength is far lower than the national standard, and it has no impact on the human body.
Features of engineering-grade wifi jammer
Shield GSM/DCS/CDMA/PHS/3G(TD-SCDMA/CDMA2000/WCDMA)/4G/5G frequency bands;
Transmit power 20W;
The effective shielding distance is adjustable from 1-15 meters (debugged before leaving the factory);
All mobile phones/walkie-talkies / DHS / PHS GPS wireless signals / wireless headsets can be shielded;
Location: Both indoor and outdoor.
The wifi frequency jammer scans from the low-end frequency of the forward channel to the high-end at a certain speed during the working process. This scanning speed can cause garbled interference in the received message signal of the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so the mobile phone is Unable to establish a connection with the base station. The mobile phone manifests as the phenomenon of searching the network, no signal, no service system, etc.
