Abstract
The present invention relates to a reverberation chamber (RC) comprising at least one antenna head attached at a first side of the chamber and a stirrer adapted to rotate. The RC comprises an arrangement to enable UE antennas to be placed at a location within the RC such that the stirrer is adapted to rotate to simulate a fading condition for the UE antennas in relation to the antenna heads attached at the first side and that RF connections from the antenna heads arc adapted to be connected to a cellular network, such as a closed cellular network.
