Can the signal blocker block all communication signals? Having said that, many people are a little unfamiliar with test signal jammers. In fact, it has been widely used in the college entrance examination room. In the college entrance examination last year, many examination rooms were equipped with this kind of equipment. The response was very good. Practice has proved that this method has a good effect on eliminating electronic signal cheating. Starting this year, it has been vigorously promoted to allow more examination rooms to be equipped with this shield.
The emergence of shielding devices now solves many hidden dangers that disrupt the order of the examination room, allowing candidates to take the exam in a fair environment. The principle of the test signal shielding device is to disable the communication signal of the mobile phone by isolating the electronic signal, thereby preventing the use of the mobile phone to cheat. Not only that, it also has a good shielding effect on WIFI2.4G signals. Generally speaking, the effective range is within a radius of 0 to 30 meters. Generally speaking, a low-power test signal shielding device is sufficient to cover the entire classroom. It satisfies the test room’s requirement for shielding signals. Since the battery life of the device is generally three hours, although the heat dissipation is not good, it also leads to a particularly high cost performance, which is especially suitable for schools to buy test room signal shielding.
