Would you like to learn more about OTA measurement repeatability? And how to combine OTA and temperature measurements? The video discusses various solutions for over-the-air (OTA) testing for 5G NR devices and base stations based on test solutions from Rohde & Schwarz.
Over-the-air (OTA) testing for 5G NR devices usually results in high measurement distances – particularly for mmWave frequencies and massive MIMO devices. The video discusses various solutions to significantly reduce the measurement distances in order to achieve a compact test setup for mobile device and base station OTA testing.

This video answers common questions that arise with 5G over the air testing. Where does the far-field start? Is the Fraunhofer distance “the” far-field distance? Do I need to know the antenna location inside the device under test? How can I measure under far-field conditions at near-field distances and remarkably reduce the test setup size?

A high peak-to-average power ratio (PAPR) is not beneficial as it challenges the non-linear power amplifier operation close to compression for maximum efficiency. A possible way out is to apply crest factor reduction (CFR) techniques such as to clip high signal peaks. This video demonstrates a simple method to clip (any) waveform, including the Verizon… Read more »
3GPP’s 5G NR will support frequency ranges up to 52.6 GHz, but initial 5G designs will use frequencies below 6 GHz with focus on 3.5 GHz. For sub-6 GHz carrier frequencies, 3GPP currently discusses a maximum bandwidth per component carrier of 100 MHz. The R&S®CMW100 communications manufacturing test set with a supported bandwidth of 160… Read more »
This video compares the performance of a V5GTF standard-compliant signal showing a standard-dependent high peak-to-average power ratio (PAPR) with a clipped version of such a signal. Did the crest factor improve? How about the error vector magnitude (EVM)?
How to analyze a 5G New Radio (NR) waveform? This video demonstrates how to create a configuration file with the R&S®FS-K96PC OFDM vector signal analysis software from Rohde & Schwarz to analyze an OFDM-based waveform that follows the physical layer parameterization for 5G NR.
This video shows the current status of 5G New Radio (NR) in 3GPP with focus on RAN1 – the group within 3GPP that is responsible for physical layer aspects.
