Shielded Room & Radio Frequency Attenuation Testing

Your confidential conversations – protected

When the most sensitive conversations and negotiations are taking place, a shielded room provides the assurance you need.

Whether your requirement is TEMPEST-rated electromagnetic security, secure speech, or anti-bugging solutions within an existing structure or as part of a new build—Esoteric can guide you every step of the way. We also offer independent Radio Frequency attenuation testing to verify the effectiveness of both new and existing shielded rooms.

Frequently Asked Questions

TEMPEST isn’t an acronym. It is a word used to describe measures and standards that protect against the interception of compromising electromagnetic emanations.

Esoteric can independently verify the performance of rooms that have been recently installed and carry out regular checks to ensure the integrity. This involves RF attenuation tests and a physical examination of the structure of the room to ensure it hasn’t been modified or changed.

It is important to recognise the difference. A Safe Speech Room ensures that audio (voices) are attenuated so that they cannot be heard from outside the room. It can also be designed to minimise the threat of surveillance devices being installed. A Shielded Room is specifically designed to attenuate RF signal.  Not all Shielded rooms offer a safe speech environment.

Shielded Rooms

Esoteric advises and supports clients on the creation of shielded rooms and containers. Constructed to protect against a variety of threats, we work with strategic partners to design solutions that will contain or eliminate the effects of electromagnetic interference (EMI).

All shielded room requirements are bespoke to the needs of the client and can be built to various performance specifications. Our capabilities include RF (Radio Frequency) shielded rooms, anechoic chambers, EMPP (Electro-Magnetic Pulse Protected) facilities, magnetic field shielding and TEMPEST shielding.

RF Testing

RF Attenuation Testing

Shielded and secure rooms must be tested regularly to ensure their continued effectiveness. Esoteric provides independent Radio Frequency attenuation testing for both new and existing room structures or containers, using state-of-the-art field measurement instruments to verify shielding performance.

All testing is conducted by Esoteric’s in-house specialists and carried out in accordance with IEEE STD 299-2006.
