The rollout of 5G NR will initiate a worldwide deployment in an unknown radio environment where unwanted transmitters can degrade end-user QoE and in some cases cause outages of critical services. Prior to deployment, operators need to ensure the radio environment is free from interference by conducting spectral clearance and interference hunting. This webinar defines… Read more »
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. Learn more about software- and hardware-based… Read more »
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.
