MIMO OTAAReverberation darkroom testing system

In response to the widespread adoption of multi standard mobile terminals and their typical multi interference urban environment applications.Swedish BLUETEST companyWe have launched a revolutionary reverberation chamber system to assist relevant customers in completing their understanding of modern wireless terminalsOTAFast and accurate measurement of performance.

BLUETESTThe latest updates from the companyRTS95/RTS65 OTAThe support for reverberation chamber system includes: GSM/GPRS/EDGE/UMTS/HSPA/HSPA+/CDMA2000/EVDO/TDSCDMA/BLUETOOTH/WLAN/WIMAX/FDD-LTE/TD-LTE/5GWireless StandardSISOandMIMO OTAMeasurement. At the same time, it can achieve efficiency, diversity gain, andMIMOMeasurement of Capacity. Especially for the latestMIMO OTAMeasurement, due to the unique design concept of the reverberation chamber, can be quickly and accurately completed without the need for additional equipmentMIMOsystemicTRP/TIS/IP-LayerThroughput rate/MAC-LayerThroughput and other tests.

BLUETEST MIMO OTAReverberation darkroom systemIt is a system developed based on a microwave reverberation chamber platformMIMO OTAThe testing plan includes patented software algorithms to control the use of mixing templates and turntables in a reverberation chamber, and to construct a standard Rayleigh fading environment. And obtained through variance calculation of a large number of samplesOTATest the required antenna efficiency,MIMOCorrelation coefficient and gain of antenna, TRP, TIS,Test values such as throughput rate. The test results have reached0.3dBVariance,Repeatability achieved0.1dBVariance value.

The system currently supports all commercially available systems2G, 3G, 4G, Bluetooth，WifiStandard productsOTATesting, supportLTE+ofMIMOTesting of carrier aggregation. be directed against5GRegarding the Internet of ThingsMassive MIMOAnd millimeter wave relatedOTAThe plan is also gradually being introduced. The system software is compatible with all mainstream base station simulators and channel simulator instruments in the market, and provides a simple, efficient, and user-friendly graphical system control interface as well as powerful test data management functions.

BluetestThe reverberation chamberOTAThe testing system is widely adopted by customers worldwide, including major operators, mobile terminal manufacturers, antenna manufacturers, certification laboratories, etc. The number of customers is close to100Home, total number of units exceeds200cover
