Some opportunistic people use mobile phones for cheating

Some opportunistic people use mobile phones for cheating, some of the terrorists and hostile elements, but also the use of mobile phone detonated bombs, the fact that mobile phones in some cases, criminals have become the tools of crime, to adversely affect social stability . The company developed the cell phone signal jammers can effectively address the issue. It as a new information security products, with specific electromagnetic signals in place to protect the formation of an electric fence network, the mobile phone base stations can not receive data, can not establish contact with the base station, eliminating the negative impact of mobile phones, from to the security role.The company is developing cell phone jammer based on the new technology. Second, the use and characteristics of 2.1 uses only a cell phone blocker for mobile phone communications have an effect on other electronic equipment without interference harmful to humans, can be widely applied. 2.1.1 The various conference rooms, auditoriums, courtrooms, libraries, examination room, schools, theaters, hospitals; 2.1.2 gas stations, filling stations, oil fields, oil depots; 2.13 government, military, financial, securities, prisons, police command center or prohibit the use of mobile phones and all places. 2.2 Features 2.2.1 cell phone signal jammers entirely by the latest chip components and integrated circuits, has a performance art, installation is simple, can work long hours and so on. The company is making every effort to produce the advanced cell phone jammer . The production process strictly follows the ISO9001 quality system, stable and reliable, is to strengthen information security, ensure safety and protect the environment, the ideal, reliable security products. Third, the main features and technical specifications 3.1 3.1.1 main function of the effective four-channel models shielding CDMA, GSM, DCS, PHS mobile signal 3.1.2 only block mobile phone signals do not affect other electronic devices to work under normal circumstances from 3.1.3 base station 200 meters away the best place to use power to 3.1.4 3.1.5 stable long slow start circuit design to avoid mechanical switch design lines generated ignition phenomena major technical indicators 3.2.1 3.2 effective shielding radius : 20-80 meters 3.2.2 shielded signal bandwidth: CDMA: 869-894MHzGSM: 925-960 MHZ DCS :1805-1880MHZ 1900-1990MHZ after upgrade 3G :2110-2170 MHZ.The meeting information security equipment contains  cell phone jammer . Working Hours: stability of long continuous work 3.2.4 Ambient temperature: - 40 ℃ to +55 ℃ 3.2.5 Relative Humidity: 30% - 95% 3.2.6 Power Adapter: Input AC 160V - 240V output DC 5V IV 4.1 installation and installation steps and instructions way out of the box 4.1.1 shielded from the host device; 4.1.2 respectively screwed into the antenna corresponding to each antenna base, otherwise invalid; 4.1.3 the shielding device to the wall or the appropriate location, the best installation height of 1-1.8 meters; 4.1.4 5V power supply output to the first host, then the AC input power into the mains socket, then turn the power switch, power indicator light, said work on the 4.1.5 to work for large, installation location to take a small space-point method, as shown below. Example 1: Indoor small space (less than 200 square meters) Example 2: a large indoor space (greater than 200 square meters, to be used more than one) Example 3: a large outdoor space (greater than 1000 square meters, with multiple cellular effects Best). cell phone jammer is the intelligent product specifically and successfully developed and manufactured by the company. Note the antenna must first be identified by the corresponding host installed, then connect the host power supply. 4.2.2 The effective coverage of jammers jammers as the center is a circular area, so pay attention to the correct choice when using jammers to avoid the placement of shielding dead.
