Abstract: Systems, methods, and computer media for testing mobile devices are disclosed herein. An outer signal isolation enclosure contains a group of test system components within. A plurality of inner signal isolation enclosures containing a plurality of wireless access points are contained within the outer signal isolation enclosure. An attenuator is also contained within the outer signal isolation enclosure and is connected to the plurality of wireless access points. The attenuator receives output signals from at least some of the plurality of wireless access points contained within the respective plurality of inner signal isolation enclosures and wirelessly transmits a test signal within the outer signal isolation enclosure based at least in part on the received output signals.
