A reverberation chamber is ideally suited for testing antennas for multi-antenna technologies such as diversity and MIMO. Bluetest Flow for diversity and MIMO measurements are well-proven and will give you instant feedback of the performance of the antenna array after the measurement is finished - no waiting time needed! In combination with the extreme measurement speed, the user will have the antenna performance in a single minute only.
Antenna efficiency goes under the category of Bluetest passive measurements in the reverberation chamber. An important parameter for all different types of antennas is radiation efficiency and is a basic parameter for all antenna designs. In fact, it is the dominating factor for antenna performance in multipath environments.
Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS) goes under the category of Bluetest's active measurements. Active measurements means that the transmitter/receiver in the DUT is active and powered up. Active measurements will give you a complete overview of how the whole system in your device is performing. These are parameters directly related to the antenna radiation efficiency, and are well proven measurements in Bluetest's reverberation chambers. The TRP and TIS measurements in a reverberation chamber are standardized and included in the 3GPP Test Specification TS 34.114.
The current trend in active device over-the-air (OTA) testing is to characterize the system performance via data throughput. With Bluetest measurement software the throughput can be measured at either IP or MAC layer in a fast, repeatable, and convenient way.
