      Yes exactly. This is a room to test for signals, wanted or unwanted coming out of the devices to be tested. I know nothing about it so don’t spy on me please lol.

      Can confirm. I’ve been in a room exactly like that, where they had an antenna mounted on one wall like the above picture, an RF reflector mounted on the opposite wall, and RF dampening cones on every surface, so that they could measure the frequency curve at a distance twice that of the size of the room (the curve changes with distance)
