cell phone jammer works in the specific frequency range
The car power invertor is needed when using cell phone jammer in the car. Fukushima in Japan we are concerned about the nuclear issue, you may have noticed, as we have around us essential things, but also threaten our health. With the scientific and technological development, people's communication equipment from the old telegraph, telephone, developed to the BB machine, PHS, mobile phone. Phone functions from the previous development of a single call to send text messages, camera, camera, or even the Internet, watching TV (movies), listen to music. With the increase of mobile phone functions, as well as cheaper prices, more and more people use mobile phones. The jamming range of cell phone jammer is determined by the local signal strength.
According to statistics, in 2010, more than 800 million mobile phone users in China, although the mobile phone has brought us a lot of convenience, but new problems have emerged cell phone radiation and pollution. When we use the phone, the phone will transmit radio waves to transmit the base station, and more or less any kind of radio waves absorbed by the body, thus changing the human tissue, it may impact on human health, these waves will be called of mobile phone radiation. University of Washington specializing in mobile phone experts have done experiments with mice, the 100 mice into a large bucket filled with water, the water is placed on a rescue raft, and then climb up the training of these mice life-saving raft. The shielding range of cell phone jammer can achieve the radius of 30m in total.
In order to climb raft of knowledge to stay long-term memory in mice, he repeated the training group of six rats. The expert, the 50 rats exposed to mobile phones with similar microwave radiation and found another 50 never exposed to microwave radiation in the mouse, still very much at home to climb the raft from the water; but under the influence of microwave mice, the almost complete loss of memory, I do not know how to climb the raft. Although the biological effects of the academic community of mobile phone electromagnetic some mechanism remains controversial, but denied it under certain conditions would cause harm to humans. A Swedish research institutions to ten thousand Swedes were using the phone survey. The results show that the more frequent use of mobile phones, their physical discomfort, the more obvious. cell phone jammer is the ideal product for any place where cellular calls is needed to be shielded.
