Nowadays, the emergence of mobile cell phone jammer has solved many hidden dangers of disrupting the order for the examination room, so that candidates can take the examination in a fair environment. The principle of this test signal jammer is actually to isolate the electronic signal, so that the communication signal of the mobile phone fails, which can prevent the phenomenon of cheating by using the mobile phone. Not only that, it also has a good shielding effect for the WIFI2.4G signal. It is said that the effective range is within a radius of 0 to 30 meters. Generally, a low-power test mobile phone signal jammer is enough to cover an entire classroom, which meets the needs of the test room for shielding signals, and because the battery life of this device is generally three. Although the heat dissipation is poor, it also leads to a particularly high price/performance ratio, which is especially suitable for schools to buy signal shielding for the examination room.
As a commonly used electronic device, mobile phone has become very common in today’s society. It is thought to be an alternative organ for people, but most young people use it unreasonably in many special places, causing many information security problems.

The use of mobile phones must be prohibited. The first thing that everyone thinks of is the school.
