5G Signaling Test Solution

For developers of 5G devices, the CMX500 radio communication tester enables non-standalone (NSA) and standalone (SA) signaling tests now in both FR1 and FR2 frequency ranges.

The tests performed in NSA mode feature both LTE and 5G connections. They verify LTE/5G signaling protocol behavior, OTA RF/TX measurements, end-to-end data testing with LTE & 5G bearers, as well as mmWave OTA signaling and RF measurements.

The signaling test in the mmWave-based 5G frequency of FR2 requires an OTA test setup or environment. For this, the test setup features the R&S ATS800R CATR rack-based antenna test system with OTA functionalities. Designed for FR2 R&D measurements, it optimizes the available lab space by combining a compact shielding chamber with T&M equipment in the same setup, ensuring the smallest footprint. The integrated state-of-the-art reflector surface precision provides a big enough quiet zone with high accuracy.

To control the 5G radio communication testers, the test setup includes the newly developed R&S CMsquares unified test software solution. CMsquares integrates the complete mobile network simulation with test configuration, parameterization, real-time measurements, and test result management in a single environment for all relevant use cases from RF parametric testing over protocol analysis to data end-to-end throughput tests.

It provides the easiest user guidance via dashboards and customizable workspaces which allow quick access to the various types of 5G measurements. It also comes in line with a built-in sequencer to run pre-configured 5G NR test scripts or to create 5G NR test scripts from scratch using a simple drag-and-drop workflow.
