Many schools have been busy lately as the college entrance exam days are counting down day by day and they are constantly preparing the materials and machines needed for the exam room. This should enable candidates to take the exam in a stable and orderly environment. This is also the responsibility of the school. So recently we can see that a machine has been installed in the examination room. This is the test signal jammer that many schools have vigorously promoted recently. It is a problem that can effectively counteract electronic signal cheating. It is effective, but what is not known is that when it is actually used, its effect will also differ depending on the installation location and situation.
Although the size of the shielding area that we saw can be found in the instruction manual that came with the shielding device for the test signal, this data is only laboratory data for reference and actual use will vary depending on different situations. If there is a base station nearby within 500 meters, this is one of the reasons that affects the shielding range and the effect depends on the length of the distance. This point should be noted. Second, the test signal jammer cannot pass the wall. This drastically reduces the shielding effect, and metal objects also affect the shielding effect. While there are several types of problems that affect the way the jamming signal works, it is still the most effective way to prevent electronic cheating. Those who choose the jammer are welcome to visit the jammer shop to find out the price of the jammer. Here you will find machines of professional quality and at preferential prices. Many years of research and development experience is trustworthy. We look forward to coming and customer cooperation.
