The cell phone jammer is a relatively professional modern communication signal shielding technology, especially in the special environment of the prison, 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. This is the time to use mobile phone signal jammers for shielding.
1. How to evaluate the effect of the cell phone signal shielding system in the prison? If there is no blind spot in the prison, the test should be repeated. In places with relatively strong signals, such as "windows" or "every corners", professional equipment detectors should be used. The construction party can also entrust the local authorities to conduct professional inspections for equipment. , Radiation, and shielding of other systems; no blind spots; compliance with the inspection regulations of relevant departments
2. The shielding effect and external shielding?
A high-quality mobile phone signal shielding system project must be completely shielded without affecting the communication of residents, not letting people complain, not allowing mobile and China Unicom to cause trouble, and the shielding area is more accurate, and there is no shielding outside the shielding area, which can be regarded as a complete acceptance project.
