5G mmWave – A Challenge for Device Testing and How to Solve It

Presented by: Günter Pfeifer, Market Segment Manager, Rohde & Schwarz, Munich Abstract: 5G NR in the sub 6 GHz frequency range (FR1) can be seen as a natural evolution of LTE to achieve higher bandwidth and more flexibility on the physical layer in order to realize all the new and additional use cases defined for a next-generation… Read more »

Demystifying 5G – Creating far-field conditions at short distances for 5G over the air testing

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. Learn more about software- and hardware-based… Read more »

Demystifying 5G – Over the air (OTA) testing for 5G NR in far-field and near-field

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?

Demystifying 5G – V5GTF crest factor reduction (CFR) – a simple way out?

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 »

Demystifying 5G – How about clipping a V5GTF signal?

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)?

Demystifying 5G – 5G New Radio (NR) waveform analysis

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.
