Many customers call me and ask for a telecom cell phone jammer with a radius of 50 meters, a distance of 500 meters, and a radius of one kilometer, and it needs to be shielded by China Mobile, China Unicom and China Telecom. Is there any problem with customer standards? No problem, there are actual spacing regulations, but is it ok? The answer is very difficult to achieve.
During operation, the signal jammer scans the low-end and mid-range frequencies of the wireless channel at a certain rate. This scanning rate can cause error codes in the packet signals received by the mobile phone, causing the mobile phone to be unable to detect Excluding any normal microwave signal data emitted from the communication base station, within a certain range, the mobile phone cannot establish a connection with the communication base station, achieving the purpose of interfering with the mobile phone signal.
It is easy to understand that the frequency of mobile phone signal interference infringes the frequency of mobile phone reception communication base stations. There is a competitive relationship between shielding and communication base stations. If the interference signal strength is lower than the output power of the natural environment communication base station to mobile phone wireless channel, then the signal cannot be shielded. , only the signal interference output power exceeds the output power from the communication base station to the mobile phone to ensure reasonable shielding. Therefore, any jammer will show different shielding distances when used in different signal environments, and China Mobile and China Unicom will also have different shielding distances, because the base stations built by these three operators are relatively dense and It is unlikely that the base station direction and its communication base station output power are consistent.
In other words, how long a cell phone signal jammer can block is not only related to its own signal strength, but also related to the distance between the base stations in the application environment (base stations are not limited to large signal transmission towers built on the ground) , there are also signal expansion antennas on the roof of the building and some signal expansion and dissemination in the building). Another important reason is the obstruction. If it is a metal material, it will be blocked immediately; if it is a solid wall of concrete structure, after passing through The loss will be at least 10 times; if it is a wood board, the loss after transmission of the laminated glass material may be smaller.
So the next time a user asks about how long the interference distance is, be sure to ask about the distance between base stations in the environment, and then whether it is used indoors or outdoors, whether it needs to pass through a wall, etc. Customers can leave a message online to Topsignaljammer to learn how to use signal jammers. Only by understanding these, can we better choose a suitable signal jammer for customers. Why is it so difficult to achieve? The main parameters of the signal jammer do not have its own shielding distance. How about placing a few more according to this distance? In fact, otherwise, the customers are not wrong, but they don’t know that the interference size of the signal jammer is not a numerical value.
