RF transmission testing inside a Faraday cage

Since there is RF expertise in the community, so I thought I'd try to get some insight into an area where I don't have much experience.

I'm currently working a project testing BLE transmitters and my current workroom location can experience a fair amount of RF noise in the 2.4GHz ISM band (primarily due to existing WiFi and Bluetooth/BLE). My primary mitigation when possible is to increase distance from or turn off noise sources. I started thinking about whether I could test within an RF shield. My previous experiences with testing within RF enclosures was over 40 years ago and we used room scale enclosures to house the equipment and operators.

I was wondering if anyone has tried small scale enclosures to shield only the EUT and measurement setup. What would be a good minimum size at this frequency?

TIA for any feedback.

Hi Ralph - Green Bank Radio Telescope Observatory has entire buildings constructed as Faraday cages. Besides being a really fun and interesting visit, it is a public treasure, open to collaboration with schools, community, etc. educational purposes. The staff is really open, alot of equipment is custom, Their engineering staff may share some tips with you on their experiences on materials and best practices for faraday cages. https://greenbankobservatory.org/

Thanks for the link. Never thought about Faraday cages with respect to observatories, but it makes sense. I'll need to look into it.
