Is wireless signal shield harmful to human body?

When the mobile phone is working, the mobile phone and the base station are connected through radio waves within a certain frequency range, and data and sound transmission is completed through a certain baud rate and modulation. In view of this communication principle, the wireless signal shield scans the low-end frequency to the high-end frequency at a certain speed during the working process. The scanning speed can cause code interference in the newspaper signal received by the mobile phone. The mobile phone cannot detect the normal data sent by the base station, making it unable to establish a connection with the base station.


Use wireless signal shield:


1. Select the area where the mobile phone signal needs to be cut off, and place the cutter on the desktop or on the wall.


2. After installation, turn on the power supply of the disconnector and turn on the power switch.


3. After the equipment is connected, press the power switch disconnector to work. At this time, all the mobile phones on site are in the search network state, and the base station signal is lost. The owner and are said to be unable to establish telephone contact.


Is wireless signal shield harmful to human body?


The appearance of wireless signal blockers has played a certain role in restraining the increasingly serious mobile phone noise pollution. However, as a mobile communication interference device, whether electromagnetic radiation will cause harm to human health has become a topic of concern. At the same time, when installing and using mobile phone shielding equipment, due to the number of installation stations. Transmission power. Override mode. Radiation control also has greater autonomy and randomness. In some places, in order to greatly improve the effective interference and shielding effect, even blindly introduce the installation and use of high-power mobile phone interference shielding equipment. The impact and harm to human body should not be worrying.


As another human product, mobile phone signal shielding will not only block mobile phone signals and ensure information security, but also will certainly bring some negative effects. However, we should see the main contradiction. Just as we no longer use kitchen knives, we will not refuse to shield the mobile phone signal, because the mobile phone information shielding may cause adverse radiation to the human body. After all, mobile phone shielding is the main contribution to ensuring information security and contributing to social stability. It is important to provide security for prisons, detention centers, major conferences and other places with high security factors.


As far as the qualified mobile phone signal shielding system is concerned, according to the scientific understanding level, there is no safety problem. This is mainly due to the following two reasons:


First of all, on the technical level, although the mobile phone signal shielding system is a new technology product, its technology should be relatively mature, so it has high security. According to the test report of an authoritative testing agency, the qualified mobile phone signal shielding system has low radiation and is usually installed at a high place, which has no adverse impact on human health.
