Germany’s Rohde & Schwarz (R&S) claims to have passed a milestone for evaluation of 5G millimeter wave equipment by developing a system, with authorization from the USA’s CTIA, for over-the-air testing of multiple angles-of-arrival (AoA) of RF signals. While rival vendors such as Keysight Communications might challenge the claim of a world-first, there is no doubt such capabilities are essential for making mmWave services work effectively for faster moving devices, such as drones, robots and unattended automated vehicles (UAVs). As R&S said, testing multiple angles-of-arrival is “critical for verifying the performance of mobile devices in the mmWave space, as radio waves at these high frequencies suffer from high path loss and therefore need to be focused in narrow beams that…
