High Frequency Shielding refers to the shielding of an entire room against external Electromagnetic Interference (EMI/RFI) signals. EMI/RFI can be caused by multiple sources, such as Mobile phone base stations and antennas, Radars (military or civilian), Radio and TV broadcast centers, large motors and drives, large inverters, lightning, etc. EMI/RFI interference can cause: AST offers a standard 30dB Shielding solution (Soft-Tempest), which is cost-effective, quick to install and secure. It decreases more than 90% the incoming strength of any EMI/RFI signal.
• Data communication signal disruption: interference can couple into data cabling (even if shielded) and disrupt the communication packets, therefore slowing down communications in a network.
• Microprocessors degradation: frequent EMI/RFI coupling causes small voltage transients in micro-processors and other microelectronics components, stressing them and shortening their operational life.
• Electronic components destruction: very strong EMI/RFI pulse can cause destruction of components.
AST solution is based on highly conductive materials, that through a specific installation technique provides a very consistent performance.
Moreover, complying with current IEC immunity standards and providing an EMI/RFI "clean" environment, is a must to specify Shielding in Data Centers.
