The RTS65 from Bluetest is a Reverberation Test Chamber for Bluetooth, WLAN, 2G, 3G, 4G LTE, mm-Wave, and the latest 5G NR standards. The chamber can be used for applications from 500 MHz to 40 GHz. It can be configured to support up to 16 antenna configurations up to 6 GHz and two mm-Wave antenna configurations at 40 GHz and 43 GHz. The 16 antenna configuration can for example support four LTE carriers with 4x4 MIMO in four different frequency bands. With its 40/43 GHz capability, the chamber is also ready for 5G NR and the combination of sub-6 GHz LTE carriers and sub-6 GHz or mmWave 5G NR carriers (Non-Standalone).
The RTS65 consists of a shielded reverberation chamber with reflecting walls. The device to be tested is placed on a turntable. The reflective walls in combination with moving reflectors (mode stirrers), and the turntable, create a Rayleigh faded rich isotropic multipath environment (RIMP) inside the chamber. This environment is very well suited for antenna and radio performance evaluation of modern multi-antenna (MIMO) devices.
The device is typically used for measuring Antenna Efficiency and MIMO/Diversity gain, Total Radiated Power (TRP), Total Isotropic Sensitivity (TIS) and Data Throughput vs received power. These measurements are done using a vector network analyzer or radio communication tester connected to one or several of the chamber measurement antennas. This system is available as a benchtop unit that measures 76.6 (W) x 78.9 (H) x 56.7 (D) inch with Ethernet, USB, and RS232 interfaces.
