Cell phone jammer is the high-tech product specifically and successfully researched

C-level shielded room at 0.01 ~ 1000MHz effective electric field and plane wave screen no less than 110dB, microwave (1 ~ 10GHz) screen efficiency of not less than 100dB, the magnetic field (0.01 ~ 1 MHz) magnetic screen effect by the 55 ~ 110 dB.

For the finished honeycomb panels, honeycomb panels overlap between the core and the frame is welded, not the user to consider (but do not rule out some low-quality products are not welded, and the possibility of using crimp, crimp connection is not allows the user to pay special attention when purchasing this issue). cell  phone  jammer sometimes can be considered as the meeting information security equipment.  Users need to be addressed is a good frame and chassis, honeycomb ventilation panels overlap between the issues. As the finished honeycomb ventilation panels frame has been made into a flange, and some have been good with solenoid gasket, when the honeycomb panels can be installed directly on the chassis. If the product is not on the cell plate frame with good magnetic sealing gasket, you need to accompanied by the users themselves, must not be installed directly without magnetic sealing gasket. Of course, the best installation method is directly welded to the honeycomb plate shield housing.  cell  phone  jammer   is the high-tech product specifically and successfully researched, developed and manufactured by the company. If the direct welding method, you can use the no-core honeycomb panel with borders, which can reduce costs.

Abstract: This paper discusses the shielding in EMC engineering, shielding technology requirements and shielding effectiveness of implementation.
Keywords: shielding material, shielding effectiveness
1 shielding technology in EMC engineering
cell  phone  jammer is manufactured through using the advanced foreign technology.Technology is used to suppress EMI shielding effective measures, in the EMI project has a wide application, summed up, mainly in the following typical applications:
a. shielded room. It is standard for EMC testing and research laboratory essential laboratory facilities, as a shield chamber, control room, amp room, load chamber shell, the shell is the reverberation chamber;
b. Electronic shelter. EMC testing for automotive electronic equipment, devices or shielding;
c. Electronic, electrical equipment, chassis, cabinets;
d. Ventilation cutoff waveguide window. Shielded room and the equipment required to install casing, used to provide air exchange channel;
e. conductive window.   cell  phone  jammer   is used for phenomena that some illegal students cheat in the college entrance examination, adult college entrance examination, self-taught examination and various other examinations in the school and students use the cell phone to chat in the class.The orifice for the video display screen;
f. conductive pad. For the equipment chassis and rack panel between the conductive connection.
