Are signal jammers harmful to the human body?
When the mobile phone is working, it is within a certain operating frequency range. The mobile phone and the communication base station are connected using electromagnetic waves, and information and sound effects are transmitted with a certain serial port baud rate and deployment method. For this type of communication principle, the signal jammer for cell phone passes from the low-end rate of the wireless channel to the high-end scanner at a certain rate during the operation process. This scanner speed can cause errors in the packet format signals received by the mobile phone. The mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone mainly performs search network. Poor signal, no service system, etc.
Currently, the commonly used signal jammers on the market have effective frequencies: 869~894MHz; 825~960MHz; 1805~1880MHz and 1900~1990MHz, etc. The functional frequency range is CDMA800.GSM900.DCS1800.PCS1900. It can operate an area of 40 meters in diameter, using DC-DCSPWM to input working voltage and 5V output voltage.
How to operate
1. Select an area where the mobile phone signal needs to be disconnected and place the disconnector on the table or wall in this area.
2. After installation, connect the disconnector switch power supply and turn on the main power switch.
3． After the equipment is connected, press and hold the main power switch disconnector to start working. At this time, all the mobile phones that were turned on on the spot were in the network search state and lost the base station signal. Callers cannot create voice call contacts.
Are signal jammers harmful to the body?
The occurrence of "signal blocker" has a certain inhibitory effect on the increasingly serious "mobile phone noise pollution". But as a mobile communication technology affects equipment, whether the electromagnetic radiation caused by it will cause harm to human health has also become a question At the same time, in the installation and use process of mobile phone shielding equipment, there is still great subjectivity and randomness in the installation quantity, signal strength, covering method, radiation source control and other fields. In order to maximize the benefits of effective impact and shielding effects, venues even blindly follow the trend and introduce the use of powerful mobile phone impact shielding installation equipment. The interference and harm caused to the human body can only make people worry.
As another product of ours, the "signal jammer", while covering up mobile phone signals and ensuring data security, will undoubtedly have certain adverse effects. However, when we look at the problem, we should see the basic contradiction. Just like we don’t use a fruit knife because it will scratch our hands when cutting potatoes into shreds, we don’t reject a “cell phone signal jammer” because it may cause harmful radiation to the body. ". After all, the "mobile phone jammer" ensures network information security and contributes to social stability, which is its specific contribution. The most important thing is that it provides reliable guarantee for places with relatively high security performance, such as cells, detention centers, major conferences, etc.
As far as mobile phone signal shielding systems that meet the quality standards are concerned, judging based on the current level of understanding, there will be no security risks.
