Tempest Acoustic & RF Shield Room

¢º Introduction

<Noise is information> The electric wave noise which occurs during the use of telecommunication devices is an important information source. The techniques to prevent eavesdropping and to install countermeasure equipment is called <TEMPEST>. This technique is used for military purpose or national information agency. The following high-tech electric wave shielding room is made of MagSheet, preventing both electric and magnetic wave with softness and convenience.

¢º Related regulations

World organizations such as CISPR and FFC put a certain restrictions on each frequency range to prevent eavesdropping from telecommunication device through power cable or other electric source. Followings are standards based on MIL-SPEC MIL-STD-188-124: strategic telecommunication system MIL-STD-1542A: drawing and install of eavesdropping detection MIL-HDBK-419A: general regulations on TEMPEST MIL-STD-461C: specifications and measurement on electric wave devices MIL-STD-285: measurement method on electric wave emission and shield
