The mobile phone signal jammer system is a relatively professional modern communication signal shielding technology, especially in the special environment of prisons, which puts forward higher requirements on the mobile phone signal shielding technology. For example, in the application environment of the communication signal shielding system of a general meeting, participants come and walk in a hurry, and there is almost no time to "search" for the blind spots of communication signal shielding. In the special environment of the prison, the number of people is dense and the activities are more concentrated. As long as the criminal has a mobile phone, it is easy to "search for a long time" to find blind spots in the shielding. Even if criminals do not search for blind spots and pervasive text messages, the missing blind spots will be exposed. Next, we will talk about the basic process of establishing a prison cell phone blocker system.
One, site survey
Structural survey: the layout of the internal structure of the prison (such as the length, width, floor height, location of the walkway, etc.), the distribution of the building environment outside the prison, and the determination of the location and distance of the base station;
Test results: the location, signal strength, and frequency distribution of each operator’s base station;
2. Design scheme simulation demonstration and optimization
1. Carry out construction according to the design plan, and then optimize according to different situations to achieve the ideal shielding effect;
2. The system shall be installed and optimized and tested step by step in partitions and slices to verify the effect of mobile phone signal shielding and detection of external interference, and further optimize if necessary;
3. Fully self-test to verify the effect of mobile phone signal shielding, external interference, and radiation detection
1, using a spectrum analyzer, testing and analyzing indicators;
2, using different standards and different brands of mobile phones to verify the signal shielding effect;
3. Use a radiation detector to verify the radiation value;
Fourth, conduct comprehensive user training, hold initial user inspection, submit system completion data, and start trial operation
1. Train users on necessary technology, principles, operation and maintenance, and effect verification;
2, in conjunction with users, conduct mobile phone signal shielding effect detection in the prison and detection of no interference outside the prison;
