RMI / EMI Shielded Room - Global EMC

RF Shielded Rooms

In almost all modern buildings, high levels of wireless RF signals are present from Wi-Fi, Radio, mobile phone transmitters, wireless CCTV cameras and intruder alarm systems. Global EMC’s RF Shielded Rooms work on the Faraday cage principle of a 6 sided metal enclosure, providing a controlled environment, free from electromagnetic interference (EMI) and ambient RF noise from entering or exiting the room.


This provides a suitable location for research and development, sensitive product testing or conducted EMC testing.
A turnkey solution is provided by Global EMC to specify, design, manufacture, install and provide final certification and testing of the complete project. High-quality internal finishes are also provided including lighting, power, data and HVAC to make the RF Shielded Rooms durable, practical and comfortable.

Providing an RF shielded environment from electromagnetic interference (EMI) entering or exiting the shielded room. The RF shielded rooms have many applications including a safe environment for immunity tests, anechoic chambers, welding rooms, TEMPEST, secure speech, R&D, Forensic and NEMP shielding. Shielding available from 10 kHz to 40 GHz.

Simplicity in Flexibility

All of our RF Shielded Rooms are designed and individually manufactured by Global EMC, enabling every installation to be bespoke and uniquely shaped to exact requirements and specifications.


The shield is constructed from pre-fabricated modular panels, each panel is fitted together on-site to form a completely “sealed” six-sided enclosure. The flexible modular system enables almost any size and shape of the room to be created. Installed as a self-supporting free standing room or architectural shielding fitted onto an existing room, the enclosures can be sized to fit the host building and maximise the usable space.


The installation has no hot works or welding and can easily be disassembled and re-located. The external façade is finished with a premium quality finish to match the client’s company colours or simply complement the surrounding space.

Finishing Touches

Upon the completion of our RF Shielded Rooms numerous options are available to tailor the shielded room to exact requirements. Rooms can be left as a bare shield for an industrial and durable finish or lined with plasterboard, melamine board or cleanroom finishes.


Office-style interiors are available including vinyl, anti-static or carpeted floors, dimmable lighting, mains power, data and furniture. For telecommunications or IT networks, raised false flooring can be provided, server cabinets and air conditioning.


To ensure the integrity of the shield, all penetrations are accounted for as required. Fire alarm, air conditioning, cameras, compressed air are just some of the limitless possibilities that can be integrated into the shield.

Shielding Effectiveness tested to EN 50147-1

Every Global EMC shielded room is provided with a Faraday cage shield. The shielded enclosure provides both an area free from external ambient signals but also can be used for devices inside the room from transmitting outside the shielding. Such as in Forensic investigation rooms

The measure of shielding performance is conventionally known as “shielding effectiveness”. 100dB in plane and microwave frequencies is generally regarded by most standards as a very high level of shielding suitable for scientific use.

Global EMC offer two levels of shielding Standard and Extended Performance. Standard performance is suitable for most shielding requirements and is typically seen in commercial testing situations. Extended Performance is usually used in high-performance Military applications along with certain high frequency needs.
