Wireless signal jammers require two complementary steps, search and monitoring. The search mode allows to detect and locate the currently activated transmitter. The monitoring mode continuously monitors the radio signal, so it can be detected as soon as a signal transmitter is activated.
Wireless wifi signal jammer should turn off all radio sources (mobile and cordless, bluetooth, wi-fi, microwave ovens) in the target area before searching. Voice-activated transmitters using any sound source. Place the RF detector in the center of the room and start the search mode. Slowly approach the location where the transmitter may be located and watch the signal level change. Sound and light display are available, the closer to the signal source, the higher the flashing frequency. A rapid increase in flashing frequency indicates that there may be hidden monitoring equipment.
If you are sure that the search is complete, activate monitor mode and place the RF detector in any convenient location. This product should remain stable to avoid false alarms. Alerts are generated when a threat signal is detected. The efficiency of radio signal detection in monitor mode depends on whether the threshold level is set correctly. In the case of a mobile phone, it depends on the signal amplitude value.
The digital signal monitoring mode of the wireless wifi bluetooth jammer should define signal levels and adjust threshold levels for mobile and cordless, Bluetooth and other similar devices. The higher the threshold, the lower the false alarm rate, but the monitoring distance should be reduced accordingly.
What are the types of wireless signal jammers?
Now our common signal jammers mainly include special signal jammers for examination rooms and camouflage wifi signal jammer.
The main principle of this kind of equipment is that within a certain frequency range, the mobile phone and the base station are connected by radio waves to complete the transmission of data and sound with a certain baud rate and modulation method. The jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during operation. The scanning speed can cause garbled interference in the received message signal. They cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station, so as to achieve the purpose of shielding the signal. No service system, etc.
Schools use full shielding during exams. Efficient shielding, maintains the normal order of the test, and adopts the design of heat dissipation strips, so you will not worry about fan noise affecting the test.
High-end secret-related places, concealed murals are installed in camouflage, especially suitable for high-end secret-related places. The shielding performance is stable and there is no phenomenon of sometimes shielding and sometimes not shielding. The shielding distance is super far, and the shielding distance can be adjusted.
In prisons, the smartphone signal detection and blocking machine makes the supervision places such as detention centers more humanized. The mural-style concealed installation prevents the prisoners and the police from having too strong resistance. The high-gain line design is easier to penetrate the iron door of the prison cell, so that it is shielded near the window, and there is no dead angle. Taking a standard prison building with a length of 100 meters as an example, only two or three units are needed on one floor to achieve 100% shielding.
