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?

Interference Hunting in 5G Networks

The tools and techniques used in interference hunting have remained largely the same across previous generations of cellular technologies. Differences in modulation, bandwidth, and frequency bands for 5G networks will however require substantial changes in how interference is detected, located, and resolved in 5G networks. This webinar will provide a short overview of pre-5G interference… Read more »
