Rohde & Schwarz says it is the first test company with an over-the-air test system that is CTIA-authorized for multiple angles-of-arrival (AoA) testing, which is an important aspect of 5G device performance in millimeter-wave bands.
R&S said that 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 are challenging to find, track and hand over while moving.”
