Collaboration demonstrates end-to-end validation of Next Generation eCall functionality across 4G and 5G networks, supporting global automotive safety standards

Keysight Technologies, Inc. (NYSE: KEYS) today announced the successful completion of an interoperability test for its UXM-based Next Generation eCall (NG eCall) solution with HEAD acoustics GmbH, a global leader in automotive acoustic testing.

As the automotive industry transitions toward 5G-enabled emergency call systems, manufacturers face the challenge of ensuring reliable, high-quality communication across evolving network technologies. The interoperability between Keysight’s test platform and HEAD acoustics’ acoustic test setup addresses this critical need—enabling automakers and system suppliers to confidently validate speech quality, network connectivity, and compliance with emerging NG eCall standards.

The test, conducted at Keysight’s Center of Excellence in Böblingen, on October 14–15, verified seamless integration between Keysight’s one-box RF test solution and HEAD acoustics’ measurement environment with ACQUA and labCORE. Together, the systems enable comprehensive validation of NG eCall functionality across 4G and 5G networks. Fallback solutions via 2G and 3G networks were also successfully tested.

This milestone comes in anticipation of evolving global regulatory standards, including the European Union’s CEN EN 17240:2024 and China’s GB 45672-2025, which will mandate standardized speech quality testing for in-vehicle emergency call systems by 2027 as defined by ITU-T P.1140 and GB/T 45314, respectively.

Key achievements from the interoperability test include:

• Verified 4G/5G IMS-SIP server connection and end-to-end audio with NG eCall
• Successful legacy eCall audio verification over 2G/3G networks
• Calibration of delay and audio levels for compliance testing

As vehicles become increasingly connected, Keysight remains at the forefront of innovation, delivering cutting-edge solutions that help the automotive industry meet the growing demand for advanced safety and reliability.

Dr. Matthias Wegerhoff, Managing Director of HEAD acoustics, said: “Customer satisfaction drives everything we do. That’s why we’re committed to offering a broad, flexible range of NG eCall solutions. The interoperability with Keysight technology brings valuable technical expertise to this mission, enabling us to jointly develop future-ready tools for next-generation voice and audio quality testing.”

Thomas Goetzl, VP of Automotive & Energy Solutions, Keysight Technologies, said: “This milestone underscores Keysight’s commitment to enabling the automotive industry’s transition to next-generation emergency call systems. By combining our comprehensive RF test capabilities with HEAD acoustics’ expertise in acoustic validation, we are delivering a future-proof solution that meets global regulatory demands and supports safer mobility."
