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.

NB-IoT: The Need for Scanner Based Testing

NB-IoT, (Narrow Band Internet of Things), also known as Cat NB1, is a standard for connecting “things” to the internet through the cellular network. This is a standard focused on machine to machine communications. The range of applications are vast, with key applications including asset tracking, intrusion detection, utility meter reporting, smart parking areas, and…

5G Antenna Characterization in the Far-Field

5G mobile devices and base stations will be operating antenna arrays and beam-steering techniques in the millimeter-wave region. The question of the far-field measurement distance is particularly critical for such technologies as a larger over-the-air test range means dynamic range issues and significantly larger cost. The traditionally used formula for the far-field distance aims at…
