Multiple Directions of Arrival Using CATR OTA Measurements

Guenter Pfeifer, Product Management

ABOUT

Günter Pfeifer is a Product Manager for OTA CATR chambers at Rohde & Schwarz headquarters in Munich, Germany. After joining Rohde & Schwarz in 1997, he spent 18 years in the field of mobile communications as a Product Manager responsible for different Rohde & Schwarz radio communications testers. He is well versed in various technologies ranging from GSM to 5G and has spent much of his time dealing with mobile broadband topics. This led to his involvement in 5G technology management before joining the OTA product management team. Günter holds a degree in electrical engineering from the University of Applied Sciences in Kempten, Germany.

Webinar Overview

This webinar presents a novel method using multiple compact antenna test range (CATR) reflectors to perform simultaneous multiple angle measurements for 5G devices that are capable of beamforming in the mmWave frequency range. Four CATR reflectors and their respective feed antennas are arranged on a planar semi-circle arc with the device under test placed on a positioner at the center of the arc.

This arrangement is designed to generate four planar wavefronts with different incidences, realizing up to five pairs of angular spreads or four switched/simultaneous angles of arrival. The objective of this setup is to reproduce configurations involving multiple base stations radiating from different directions. The initial target application is radio resource management (RRM) testing, where the execution of mobility procedures and radio link monitoring of a 5G mmWave device are evaluated over the air.
