The main method of using the signal jammer is to first select the area where the mobile phone signal needs to be cut off, and place the cutoff device on the desktop or wall in this area. Then, after the installation is completed, turn on the power supply of the disconnector and turn on the power switch. Wave Bubble Cell Phone Blocker After the device is connected, press the power switch and the disconnector to work. At this time, all the mobile phones that are turned on on the scene are in the state of searching for the network, and the base station signal is lost. The calling party and the called party cannot establish a call connection. We all know 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. According to the above communication principle, cell phone jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station.
Wireless Wave Bubble Cell Phone Blocker requires 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 cell phone jammers 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 signal 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.
