As of October 1, 2021, China Mobile requires all 5G enabled mobile phones to support voice services over 5G NR (VoNR). Accordingly, the network operator has announced corresponding audio quality test cases. China Mobile relies on the R&S CMX500 radio communication tester from Rohde & Schwarz for 5G VoNR test verification, and the first acceptance tests have already been performed.

On the other hand, RF Wireless power transfer (WPT) is an on demand maintenance-free powering method that enables devices to be powered at a distance, while in use, and while in motion. In this presentation, we will address how the challenge of the low efficiency of RF WPT can be tackled by shaping the transmit signal waveform.

SA Mode According to 3GPP 38.521-1

Device certification for compliance with 3GPP specifications is a crucial step in the launch of 5G NR user equipment (UE). As the demand for high-performance connectivity continues to rise, ensuring that devices meet industry standards is essential for delivering reliable and efficient service. To ensure optimal modem performance, RF pre-conformance testing, also known as design verification, needs to be initiated early in the product development process. This approach enables teams to swiftly identify and address potential issues, minimizing delays and enhancing the overall quality of the final product.The R&S®CMX500 3GPP RF pre-conformance WebGUI solution offers a fast and intuitive platform for executing NR-FR1 Standalone (SA) test cases based on the 3GPP 38.521-1 specification. Its manual verification capabilities make it particularly well-suited for early-stage validation, debugging, and step-by-step verification of test cases, leveraging the comprehensive toolset provided by the R&S®CMX500 WebGUI. Test case procedures are optimized for R&D use cases, while using the most relevant configurations from the specification.This application note serves as a comprehensive guide for R&D professionals, detailing the setup, configuration, execution, and verification of selected 3GPP pre-conformance test cases with just a few clicks in the GUI. Please note that the test steps outlined in this document require the CMX-KC661B license (SA FR1 3GPP RF Test Scenarios), in addition to the NR signaling license CMX-KS600B and the NR FR1 measurement license CMX-KM600. All descriptions, configurations and limits are based on 3GPP TS38.521-1 V18.4.0 (2024-11).

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.

The new R&S RTS radar test system from Rohde & Schwarz simulates driving scenarios for testing radar based advanced driver assistance systems (ADAS) and radar sensors used in autonomously driving cars (AD) entirely over the air. The test solution consists of the new R&S AREG800A automotive radar echo generator as a backend and the R&S QAT100 antenna array as a frontend. Laterally moving objects, i.e. objects approaching from the side, are currently simulated by mechanically moving antennas. The R&S RTS replaces the mechanical movement by electronically switching individual antennas in the frontend on and off. Even objects moving laterally to the car at very high speed can be simulated reliably and reproducibly. The R&S RTS is able to simulate the radial velocity (Doppler shift) and the size (radar cross section) of objects at user configurable – including very small – ranges. Countless objects can be represented by cascading multiple R&S AREG800A backends. The R&S RTS moves tests currently performed on the road to the lab. This allows early error detection and a significant reduction in costs.

All wireless devices must be tested for radiated spurious emissions (RSE) to verify compliance with national and international standards such as ITU, ETSI and FCC. The configuration required is similar to an EMI measurement setup, with the additional challenging task of measuring the low level spurious emissions in presence of the carrier frequency of a wireless device. The R&S®TS8996 RSE test system handles these tasks with a single setup and covers all relevant carrier frequencies and bandwidths used in wireless communications.
