What is the impact of the test site shield on people?

  • 2022/11/02

Examination sites, prisons and detention centers often use signal shield to prevent illegal use of mobile phones. Signal shield shields mobile phone signals by interfering with the downstream signal of the base station. The principle of the test site shield is that the frequency emitted by the shield itself interferes with the normal frequency of the mobile phone receiving base station, making the mobile phone unable to connect to the base station, and thus unable to receive calls, receive text messages and access the Internet normally.

As a kind of interference device, whether the electromagnetic radiation generated by the test site shielder will harm human health is also a concerned issue. The signal shielder can cover the mobile phone signal, protect the information security, but at the same time, there will be some negative problems. The mobile phone shielder will produce some radiation, but the radiation is very low and will not have adverse effects on human health.

According to the test report of the authoritative testing organization, qualified test site shield is not a safety problem, and when choosing test site shield, the appropriate signal shield should be chosen according to the area of use. Do not over-exact the effect of shielding to maximize. Using shield equipment with too much frequency will not only cause waste, but also radiation from equipment with a large frequency will naturally have some impact.

When using the test site shield, the mobile phone may still have a signal display, which is a false signal. When the test site mobile phone signal shield is turned on, the mobile phone cannot exchange and connect with the outside electromagnetic waves. When the mobile phone loses its signal, it will always search for the signal. The power consumption of the mobile phone will increase. If you turn on the test site shield, try to turn the mobile phone off or turn on the airplane mode. In order to avoid serious power consumption caused by mobile phone searching for signal all the time.
