200mW green Laser Pointer applies the 2.4G technology | Yearly Blog

System, a mobile phone screen, cell phone screen cell phone shielding system-defined system, also known as cell phone signal shielding system, multi-module by ordinary machines and related high-power low-power unit module, digital synthesis frequency hopping unit module, high-power field case, different points and gain antenna design and installation technology, science form a complete set of wireless signal shielding system can cover large areas, modular combination of simple, reliable and easy to upgrade, etc., for the wireless signal shielding engineering, modular combination inside the machine with high performance and low cost to satisfy customer requirements. The green laser pointer contains the two functions of page-turning and remote controlling in one.Second, the mobile phone screen introduced a system-related components. Prerequisites phone screen 1) shielding the system host device, such as BLS-350I (indoor shielding the host), BLS-350II (high-power field host) 2) shielding system dedicated antenna, such as flat panel antenna, angle the antenna, Yagi antenna, etc. 3) shielded cable system-specific, such as coaxial cable, leaky coaxial cable, etc. 4) shielding system-specific accessories, such as splitters, couplers, etc. 2. Optional mobile phone shielding system components 1) TD TD SCDMA mobile device synchronization particularity, in order to prevent signal interference shielding TD SCDMA base station running, set the proposed increase in TD subjects synchronizer. 2)200mW green Laser Pointer applies the 2.4G technology, which is direction-free with long wireless distance. JKDZ2010 screen smart phone alarm system monitoring screen of this phone system integration module alarm monitoring, real-time monitoring system of the host state shield three mobile phone shielding shielding system design principles Design principles: advanced technology, reliable, practical, based on necessary, take precautions to ensure safety. 1) Ensure that shield block mobile phone signals within the region (including China Mobile, Unicom, Telecom), but does not affect radio communication; 2) ensure that the system in the harsh environment 24 hours a day running of the high stability; 3) ensure security of the system ( strict control system to produce band rejection of the basic electronic devices will not have an impact); 4)This 50mW green laser pointer contains the USB1.1/2.0 interface port, plug and play. The authority system equipment through rigorous testing, electromagnetic radiation on the human body in line with national safety standards; 5) to ensure the scalability of the system, leaving blind spot; 6) the overall system optimization. Fourth, the phone system designed to shield the public communication system based on the frequency band to determine the shielding range.The micropower emission of green laser pointer
Specifically, is divided evenly to the face 16 points, with isotropic field probes measure the field strength at each point, taking the value closest to delete the other four values of 12, 12, maximum and minimum values as the difference is less than 6dB, is that the test surface is uniform, the sensitivity of certified electromagnetic radiation can be detected. 12 IV. shielded cabinet up GJBz20219-94 in Class B, Class B structures shielding shell: PSD: filters: air waveguide Window: waveguide: Server bracket: cold-rolled steel plate welded into the fully enclosed cabinet, after galvanizing and painting anti-corrosion treatment; 100mW green laser pointer high-quality materials have been carefully shielded reed production and processing, cold-rolled steel plate welded into the composition of the doors PSD; The micropower emission of green laser pointer does no harm to human bodies, which is green, healthy and environment-friendly.power filter with wide suppression band and high insertion loss; honeycomb ventilation waveguide windows, waveguide window with the top two miniature axial fan, single exhaust volume 1.4m3/min; 14 * 100 Copper fiber-optic transmission conduit; the location of the upper and lower front and rear adjustable mounting brackets server; electrical sockets and switches.
