Hmm, I don't think that is the same thing as an anechoic chamber. A shielded cell would have all kinds of internal reflections but may allow you to determine some upper bound on the RF radiated from a device or, using a sampling antenna inside the chamber, to expose a device to a known RF intensity. However, if you are going to investigate antenna pattern or need to control the direction of test signals, you would need the anechoic features.
