The cell phone signal jammers can be formed in a specified position

Size: 270 * 120 * 34mm Weight: 1.6Kg shielding radius :20-50m (depending on base station distance) products include: host 1, a power adapter, omni-directional antenna Ruanbian five applications: five-channel signal transmission, Built-in cooling fan, can turn over many years continuous use, long life, for prisons, factories, take a long time in the workplace. Cell phone signal jammers Roundup: mobile phone signal jammers Summary: With the rapid development of mobile communications, mobile phones have become an essential communication tool, mobile phones to bring convenient, fast and it has also a very high frequency and RF radiation, which is we all know, and how much of this radiation hazards, and we may not all know. The effective shielding range of cell phone jammer is a circle area centers on it.This mutation of the radiation signal, the light interference of precision instruments and equipment around the work, such as in hospitals, will affect pacemakers, ECG recorders, and other similar sophisticated equipment, leading doctors to diagnose errors. In severe cases, cause a static spark, ignition of combustible gases, the gas station, filling stations, chemical storage, oil refineries, hazardous materials storage yards and other areas of significant security threat. The cell phone signal jammers can be formed in a specified position within the magnetic shield (ie the mobile phone can not receive this signal), the mobile phone (including China Telecom, China Unicom and various PHS) within the specified range can not be played and access, will not be able to form the radiation signal mutation, so as to achieve the purpose of mandatory disabled mobile phone, the security of the above sites offer great protection.When use the cell phone jammer, please place it in a right shielding position. SMa SMa-818W mobile phone jammer jammer Usage of this subsection by the company independent research and development, production, which can effectively shield between the transmitter and the mobile phone microwave signal. As the original jammers imported devices with a new, professional welding machine placement, assembly line mass production, strict and efficient management to ensure a first class product quality, performance, stability, and long-term durability. SMaSMa-818W-type mobile phone signal jammers Features SMa-818W mobile phone signal jammers, over a long period of testing and field testing of user feedback showed that the jammers have formed their own unique characteristics: small size, light weight, this paragraph jammers volume: 270 * 120 * 34mm, weight: 1.6 kg. Place the cell phone jammer in the right position to avoid generating the dead angle.Simple, easy to install jammers in this paragraph only the antenna is properly connected, power on, you can work. Dealers or customers to read our training materials to the installation method to master the on-site installation. Installation according to security standards required, placed in walls, ceilings and other locations. . Band covering the whole, the range can choose a variety of shielding GSM, CDMA mobile phones, including PHS, 3G can be shielded, and only mask the base station downlink signal frequency does not interfere with the uplink frequency, does not affect the normal operation of the surrounding base stations, which Other brands of jammers is not necessarily impossible. Better install cell phone jammer at the ventilated place.200 meters away from the base station, the coverage radius of 20-50 meters, plus more directional antennas the range can be expanded.
