for EMP ,EMC E.E.G., E.M.G. and E.C.G. equipment from external RF emitters or

RF emissions from similar equipment within hospitals, laboratories ,startup company and military companies .

RFI room create an RF isolated environment  (faraday cages, shielded chamber )

An RFI room is a room that attenuates Electromagnetic signals 10KHz to 40GHz ).
This attenuation allows operating a electronic equipments inside the RFI room in a way that will not interfere with the operation of external to any  networks

Dolev can provide solution to EM Emanations and their control at a facility level, and provide installing
and testing a shielded enclosure in a facility.

The RF shielded enclosure meets the requirements for electromagnetic attenuation through tests conducted by a third party following test methods: EN 50147-1, NSA 65-6, or IEEE 299. MIL-STD-461
