GNSS signals (for example GPS signals) are of major importance for positioning and tracking, orientation and safety-related information, such as congestion, in road traffic. A collaboration between AVL and Rohde & Schwarz, two of the world’s leading providers of measuring and automotive testing systems, now permits the reproduction of realistic GNSS reception conditions for testbed vehicle testing. As a result, users can reliably test all aspects of GNSS-based vehicle positioning – a core functionality of autonomous vehicles.

Kyocera has developed an innovative mmWave phased array antenna module (PAAM) that simultaneously creates multiple beams in different directions at different frequencies. These PAAMs can enable a wide range of 5G FR2 infrastructure installations, including site co-location of different operators running networks on different frequency bands, as well as critical infrastructure threat-sensing, homeland security, and other high-reliability applications. To ensure optimal beam steering and beam directivity of its groundbreaking product, Kyocera relies on CATR-based multi-reflector Over-the-Air (OTA) testing technology from Rohde & Schwarz.

With research on the technology components for the future 6G wireless communication standard in full swing, the possibilities of an AI-native air interface for 6G also are being explored. Rohde & Schwarz, working with NVIDIA, is taking a step forward from simulations to implementing artificial intelligence and machine learning (AI/ML) in future 6G technology. At MWC Barcelona, the companies will present the industry’s first hardware-in-the-loop demonstration of a neural receiver, showing the achievable performance gains when using trained ML models compared to traditional signal processing.

This application note addresses the diverse possibilities of interoperability between Rohde & Schwarz power sensors and Rohde & Schwarz signal generators. All current and many legacy Rohde & Schwarz signal generators offer the capability of directly connecting power sensors. This enables power measurements without the need of a base unit or separate PC to display the readings. Furthermore, sensors can be used for special tasks like filling a user correction table or continuously controlling levels at crucial points in the measurement configuration.
