An intelligent connected vehicle (ICV) is fitted with a myriad of wireless systems (V2X, cellular, Bluetooth, satellite navigation). To ensure the reliability and integrity of vehicle operation, engineers must perform full vehicle communication performance testing in a real environment. The two major challenges of the test are how to perform a near field antenna and EIRP/EIS test under the eccentric condition, and how to rebuild a real-world transmission environment in the lab and execute the MIMO performance test.  AeroGT Labs overcome these challenges with RayBow, an Arc + Arms-based automotive OTA solution, where multiple probes are fixed using electrical switching, and coordinate with the rotation of the vehicle on the turntable to perform 3D wireless performance test.
