Cell phone signal jammer to prevent 5g signal

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.

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.
