The function of the mobile phone signal jammer is to intercept the signal, and it is used in many places. The most application place you have touched is the test field. Nowadays, the transmission rate of messages is extremely fast. With a mobile terminal, all kinds of messages can be delivered to every place in an instant. For some places where messages cannot be delivered, shielding devices are particularly necessary. Being. Below I will introduce to you the working principle and function of the cell phone jammer.
The working principle of the mobile phone (radio communication) is as follows: In the corresponding frequency area, the mobile phone and the communication base station are connected together by electromagnetic waves, and the data information and audio transmission are realized with the corresponding baud rate and deployment method.
For the above communication working principle, the shielding device scans from the low frequency to the high of the forward communication channel at a corresponding rate in the operation process. The scanning rate can cause error code interference in the text signal received by the mobile phone, and the mobile phone cannot monitor the conventional data information transmitted from the communication base station, so that the mobile phone cannot establish a connection with the communication base station. The mobile phone is manifested as a bad signal, no service system, etc.
It only intercepts mobile signals and does not interfere with the regular operations of other electronic products; only intercepts mobile signals in the test site, which does not interfere with mobile phones outside the test site, and is less likely to interfere with communication base stations; only intercepts the downlink frequency of sending communication base stations without interfering with the uplink frequency; low Carbon is environmentally friendly, the electromagnetic field strength is far less than the specified standard, and there is no other interference to the body; it is easy to operate, and the external antenna is reasonably assembled, and it can be started automatically when connected to power supply.
Select the area where you want to disconnect the mobile signal, and place the disconnector on the desktop or wall of the area. After the assembly is completed, the disconnector is connected to supply power and the switch is enabled. After the mobile phone signal jammer device is connected, tap the switch to disconnect the device to work. At this time, all the mobile phones enabled on the scene are in the network search situation, and the communication base station signal is lost. Neither can establish a voice call contact.
