Every junior high school and high school will face the middle school entrance examination or the most important test. Many schools are actively preparing for the things needed in the test room. In order to ensure the normal order of the test room and eliminate the phenomenon of mobile phone cheating, the test room jammer is an effective way to prevent cheating. However, its effective shielding range is limited, so many people have questions: Is the signal shielding device still effective after passing through the wall?

Super High Power 5G Signal Jammer

In fact, let us analyze the specific situation of this problem. First of all, we need to know what the power of this signal jammer is, because it is divided into 12W, 16W and 18W; high power or low power; the effective range of different power generation is different. If it is only a small power, it is generally used in a small open place, just enough to meet the size of a classroom. However, the effect of the signal is greatly weakened after passing through the wall, so choose a low-power isolator that needs to pass through the wall as much as possible, or you can use a low-power isolator in each classroom, so that it can meet the daily examination needs. Powerful, one machine can satisfy several classrooms. In general, the selection of the test room shield is based on the size of the site, the actual functional requirements of the test room, and the frequency band required for shielding. .
