How to use signal jammer work and matters needing attention
2021-10-07
Applicable places:
1. Protection of communication signals of border operators
2. Army combat needs
3. Detention centers, labor reform teams, large and medium-sized prisons
4. Large gathering place
5. Safety precautions for leaders' visits
6. College entrance examination, adult college entrance examination, self-study examination and various colleges and universities
7. Various large, medium and small meeting rooms, concert halls, theaters for party and government agencies, enterprises
8. Gas stations, oil depots, oil fields, gas stations and other flammable and explosive places
Instructions:
1. Select the area that needs to cut off the mobile phone signal, and place the cutoff on the desktop or wall in this area.
2. After the installation is complete, turn on the power of the disconnector and turn on the power switch.
3. After the equipment is connected, press the power switch and the disconnector to work. At this time, all the mobile phones turned on at the scene are in the state of searching the network, and the base station signal is lost. Both the caller and the caller cannot establish a call connection.
Introduction to the principle of mobile phone signal jammer (mobile phone signal interceptor)
In view of the above-mentioned communication principle, the mobile phone jammer scans from the low-end frequency of the forward channel to the high-end at a certain speed during operation. This 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. The mobile phone is manifested as the phenomenon of searching the network, mobile phone no signal, no service system and so on.
Question answer:
1. Why is the shielding range different from the description in the manual when the shielding device is working?
Answer: The shielding range of the shielding device is related to the strong electromagnetic field at the shielding site and the distance from the communication station. Generally the best is 200 meters away. The manufacturer has tested it under normal conditions, so the shielding range will be slightly different.
2. Will there be radiation when the mobile phone signal is shielded, and is it harmful to the human body?
Answer: Regarding radiation, as long as electronic products are large and small, there will be radiation. Any piece of electrical equipment will have radiation. Just like the mobile phones we usually use, it is inevitable that there will be radiation when leaning against our ears every day. The country has also set a standard for mobile phone radiation, and the radiation generated by our mobile phone signal jammers is much lower than the national standard, and it is not every day. Lean against the ears, so there is almost no harm to the human body.
