Mobile phones usually use low-frequency radio signals to transmit information. In the process, people may be exposed to bad radiation, especially when streaming or downloading large files. Radio frequency (RF) energy mobile phones must transmit information through radiation, and studies have shown that if people do this frequently, they may endanger their health.
Although the current research is still unable to prove that mobile phone radiation is harmful, a large number of studies have shown that there is a close connection between mobile phones and people's health, especially for children. Several cities, including Berkeley and San Francisco, have now received notices from the state, advising citizens to keep their mobile phones away.
Dr. Devra Davis of the Environmental Health Trust said that it is unwise to make a call. In fact, the mobile phone manufacturers themselves agree. For example, Apple added "rf contacts" notifications in its "iPhone Settings". The notice is that the rf radiation range of the iPhone has been tested. It is 5 mm away from the human body, which is the thickness of a ballpoint pen and meets US safety standards. But the notice also recommends the use of speakers or hands-free devices to reduce radiation exposure, which is no different from California's new guidelines.
Dr. Davis said that most people do not realize that this is a clear warning not to keep the phone away from the body, but away from the body. What is particularly worrying is that most parents do not even pay attention to these warnings. They cannot control their children and expose their children to radiation damage from mobile phones. So when you sleep, don’t put your phone too close to yourself, otherwise it will affect your health.
If the above situation cannot be avoided, signal jammer can solve the problem of mobile phone radiation when people sleep. Cell phone jammers are specifically designed to block cell phone signals, and there are also WiFi jammers designed to block WIFI signals. Turn off the mobile phone signal, WIFI and GPS signals are also subject to some interference. First of all, you need to use the built-in antenna mini dual-frequency GPS jammer for charging, and the effect is better when charging.
Buying a wifi jammer is considered the best way to protect yourself from hackers and attackers, and 0.2 types of radio signal jammers have been invented. They are portable portable jammers. Therefore, you can choose between them. I am happy to provide WiFi interference. If you only use devices such as WiFi jammers, you may restrict access to intruders. Cheap WiFi is popular with many young people. But one disadvantage is that children spend too much time on WiFi phones, addicted to the Internet and affect their learning.
