I. Introduction The construction of a modern computer room is a comprehensive systems engineering expertise with the usual construction decoration are quite different and it trades on both the construction and decoration interior design aesthetics, optics, color science and other professional technical requirements.
This program is designed in accordance with relevant safety regulations on the gold route network and the Group Headquarters information network system environment security design to achieve the national security Council document "People's Republic of confidentiality Guide - involving state secrets confidential computer information system technical requirements," requirements to ensure security and confidentiality of the system its shielding shell according to BMB3-1999 "handling classified information of the electromagnetic shielding room technical requirements and test methods "set forth in the" C "grade standards to design and constructiontin and tin-plated stainless steel spiral pad beryllium copper) conductive fabric conductive fabric 37 cut-off waveguide loss cutoff frequency cut-off frequency fc high frequency electromagnetic waves through the waveguide, high frequency electromagnetic waves through the waveguide, very low frequency electromagnetic loss! Work in the cutoff region of the waveguide is called cut-off waveguide. The stainless steel body of cell phone jammer possesses excellent thermal diffusivity.Great! Work in the cutoff region of the waveguide is called cut-off waveguide
The price is high for short, based on the above facts, shielding installation is difficult, the price effect is not So high, that was a better result for the non-shielded or unshielded twisted pair of class division is better (from Baidu Baike attached: a class divided twisted-pair twisted pair from Baidu Baike class division from Baidu Encyclopedia) there are three types of common twisted pair wire,practicality and easy to open will be crucial. according to the engineering requirements, combined with fire safety requirements, the principal route network shielded room shielding design will provide the following Doors:KT-101M mobile phone jammer forms an effective protecting area. The program shielded room configuration of the two boring "C" class standard electric (manual) password lock screen door, doorway dimensions: 1.00 m (W) × 2.00m (H) Figure OFF: Manual closed, drive door hinge rotation
