Anritsu Company and AeroGT Labs have partnered to provide the best 5G Multiple-In Multiple-Out (MIMO) Over-the-Air (OTA) test platforms to characterize, test and optimize antennas. The platforms perform performance and reliability testing of single- or multiple-use antennas on products, such as vehicles, mobile devices, and similar designs, in a simulated environment prior to release.
Vehicle antenna performance is critical in advanced self-driving vehicles and critical automotive safety features, such as eCall. In modern vehicles, there are a minimum of 15 on-board antennas that link communication, entertainment, autonomous driving and safety subsystems. They must be tested individually and simultaneously to ensure that they function properly and that they can coexist.
“The millimeter wave (mmWave) frequency range is characterized by high performance and robust reliability and is ideal for 5G MIMO OTA candidacies,” said Steve Wang, marketing director of AeroGT. “While performing OTA MIMO measurements in a millimeter wave anechoic chamber is necessary to obtain reliable and accurate measurements, a myriad of other instruments, such as vector network analyzers, signal generators and automation software, are required and must be integrated to form a fully functional system.
“Our turnkey solutions use best-in-class products and technologies. The systems integrate solutions from General Test Systems (GTS), a company specializing in mobile device, antenna and OTA testing, and Anritsu, a global provider of innovative communications test and measurement solutions. .
“Anritsu’s MT8821C Radio Communication Analyzer and MT8000A Radio Communication Test Station are proven and critically important solutions for MIMO OTA test,” said Adnan Khan, Director of Technology and Market Development for Anritsu. “The high dynamic range RF performance of the MT8000A and MT8821C enables successful 3GPP-specified radiated two-stage (RTS) testing in a MIMO environment.”

China Intelligent and Connected Vehicle Research Institute (CICV) beijing standardized on a OTA MIMO measurement system using automotive communication performance measurement system developed by GTS, Anritsu MT8000A and MT8821C instruments, and integrated by TOYO Corporation. It supports CICV’s efforts to codify wireless communication standards for intelligent connected vehicles (ICV).
The system uses GTS’ patented RTS method, a technology approved by 3GPP as a test method for mobile terminals and base stations for measuring in-vehicle wireless communication performance for connected vehicles. The GTS RTS implementation speeds up the measurement cycle without sacrificing accuracy.
These 5G MIMO OTA The solutions can be used at many stages of product development – from research and development to quality assurance and production testing. Industry professionals looking for OTA testing capabilities can contact the experts at AeroGT or Anritsu for more information or a product demonstration.
