A method for the dynamic configuration of a test chamber for wireless communications is provided. The method includes identifying a current test project to be performed on a test device. The test device is disposed within a test chamber for evaluating one or more interactions of the test device with a wireless communication network. The method also includes determining a test configuration of a wireless connection interface of the test chamber based on the identified current test project and then sending a control signal to the wireless connection interface to set the wireless connection interface to the test configuration. In operation, the test configuration of the wireless connection interface controls which of a plurality of wireless signals of the wireless communication network are emitted within an interior the test chamber.

A method with which the reception sensitivity of a communication device can be measured accurately and with satisfactory reproducibility and a method with which the effect of noise control performed upon a communication device can be accurately evaluated. A first communication device in a nonreflective environment in an anechoic chamber wirelessly receives a test signal transmitted from a pseudo base station through an attached antenna thereof at the same time when a second communication device near the first communication device receives the test signal through a signal line. The first communication device is simultaneously subjected to the interference of noise generated by the second communication device at the attached antenna. Thus, the noise is made to interfere with the attached antenna of the first communication device without disassembling the first communication device and moving the first communication device in the nonreflective environment.

A method for measuring performance of at least one DUT in a reverberation chamber over a frequency band, the method including, iteratively: generating a fading scenario by the reverberation chamber; identifying at least one measurement sub-band included in the frequency band, wherein the at least one measurement sub-band complies with a gain flatness criterion; measuring performance of the at least one DUT in the at least one identified measurement sub-band, thereby generating at least one performance measurement result; accumulating the at least one performance measurement result; and determining measurement coverage and terminating the performance measurement in case the measurement coverage meets a coverage criterion.

A testing bench can be used while testing wireless telecommunications devices. In some examples, the testing bench includes a first surface and a second surface that houses a patch panel, a combiner, and/or an attenuator. The testing bench can be located in a shielded enclosure with at least two conductive radio frequencies (RF) shield layers separated by an insulator material. In some examples, the testing bench may receive a radio signal from a radio source located outside of the shielded enclosure and provide the radio signal to a wireless (UE) device under testing via the patch panel, the combiner and/or the attenuator.

A measurement module receives a defined system topology and system component characteristics information for a system. The measurement module calculates an expected system impedance for the defined system topology. The measurement module collects one or more impedance measurements using a high frequency voltage stimulus. Finally, the measurement module compares the one or more impedance measurements with the expected system impedance to determine adequacy of protective grounding of the system.

Each antenna and the corresponding reflector together are configured to provide a corresponding quiet zone at the test location. At least two of the several antennas are located within a main plane, whereas at least one of the several antennas is located in an auxiliary plane that is offset with respect to the main plane.
