In response to this phenomenon, the examination Signal jammers also came into being, this kind of equipment can prevent the occurrence of electronic signal cheating in the examination room in an orderly manner.
But many people still don’t understand the principle of this device. In fact, its principle is not complicated. The function of the test signal jammer is to isolate the communication signal of the mobile phone and the 2.4G WIFI signal within the shielding range.
