Rohde & Schwarz, Fujikura, and Avnet validate CATR OTA test systems for 5G mmWave phased array antenna R&D testingDesigning a 5G FR2 phased array antenna module (PAAM) requires over-the-air (OTA) testing to measure parameters like equivalent isotropic radiated power (EIRP) and effective isotropic sensitivity (EIS) in addition to traditional radiation patterns. Rohde & Schwarz has joined Fujikura and Avnet to validate their new development kit for 5G mmWave phased array antenna modules. The R&S ATS800B benchtop CATR OTA test system from Rohde & Schwarz is ideal for prototype testing in an open environment.

Rohde & Schwarz and HEAD acoustics demonstrate test solution for 5G voice over NR (VoNR) voice serviceTogether with HEAD acoustics, Rohde & Schwarz has successfully verified voice services over 5G NR (VoNR). The test solution employs the latest generation of the R&S CMX500 wideband radio communication tester, combined with the labCORE hardware platform from HEAD acoustics and their ACQUA measurement and analysis software. This setup allows simulation of a voice connection in both 5G (VoNR) and 4G (VoLTE) networks. This enables manufacturers of 5G capable telecommunications devices to test the voice quality of their devices at an early stage before market introduction. The solution was presented at the Mobile World Congress in Shanghai in February 2021 for the first time.
