Along with the rapid development of communication, wireless technology development, now is the people in mobile communications tools, essential to comfort, to bring people in, and there are some special places, such as the influence brought etc to prison, a safe need people to the wireless communication begrenzen.Das mobile GPS jammers as the name implies, is cellular functions outside of its operation, with mobile communication device shielding electromagnetic signals launched so that the same frequency of electromagnetic interference can can identify important and useful electromagnetic waves, to determine in a particular area, screened link with the main base, thus achieved the purpose of cell phone use verboten.Sie know in the room with the complexity of the existence of the human body, some electromagnetic wave is an advantage , are some electromagnetic waves for humans you sch?dlich.Bestimmen whether the electromagnetic radiation on the human body, produce a negative impact on the strength of electromagnetic radiation, mainly from the radiation direction and the distance with radiation in such aspects as integral consideration. We know that the electromagnetic shielding of radiation from mobile phones carried by the antenna to point to the selection and design of the antenna mounted directly on the quality of the screening system. To assess the electromagnetic wave of human impact, the protection to control the health of people, all countries formulate their electromagnetic protection Standard.Sprechen us about the installation of the electromagnetic shielding of mobile phone after the work environment.The frequency of the cell phone screen: 800 -880MHz characters: 870, 900,000,000,000,000: 930-960 MHz, 1805-18000000000000 1850MHz, 1900, 1900-1920 characters: MHz, these frequencies are for the job, GSM and CDMA frequency range einstellen.Durch the electromagnetic radiation intensity and frequency characteristics the human body, potential adverse effects can cause the threshold, the environment will be divided into 2 kann.Prim?re standards for safety and environmental protection in the electromagnetic force under standard conditions of electromagnetic radiation intensity live, work and life for all people (including infants, Pregnant women and people who are very weak), are not affected by the harmful effects of the area, special building, remodeling or expansion of radio and television stations, and radar station etc, its inhabitants antenna coverage area must meet the requirements of the ?standard? level entsprechen.Sekund?re standard solution for the central region in this environment to live for a long time to live, the intensity of the electromagnetic wave in all human and labor (including infants, pregnant women and people who are very weak) can lead to potential side effect of the area , this area can build factories and authority, but not allowed to build residential, learn, build hospitals and nursing homes, has adequate measures ergreifen.Mehr than 2 standard of the human body, can bring about the harmful effects, in this to reforest the area or planting to harvest to make to ban but to all the people living and often build the activities of public institutions, such as organ factories, shops and theaters and so on. In this area, this building should be taken, or to limit the time of radiation.
