HEAD acoustics Enables End-to-End Validation of Next-Generation eCall Systems
Case Studies
Keysight and HEAD acoustics completed interoperability testing between Keysight’s UXM-based Next Generation eCall solution and HEAD acoustics’ acoustic test environment, including ACQUA and lab CORE. The work demonstrated end-to-end validation of NG eCall functionality across 4G and 5G networks and successful fallback verification over 2G and 3G networks.
Keysight and HEAD acoustics connected Keysight’s UXM-based NG eCall solution with HEAD acoustics’ measurement environment, including ACQUA and lab CORE. The test was conducted at Keysight’s Center of Excellence in Böblingen and verified seamless integration between the Keysight RF test platform and the HEAD acoustics acoustic test setup.
The Keysight E6950B eCall Conformance Test Solution supports validation of eCall, ERA-GLONASS, and NG eCall systems. In this collaboration, the solution enabled RF and network test capabilities that could be used with HEAD acoustics’ acoustic measurement tools to evaluate emergency call performance across cellular technologies.
Together, the systems created a more complete validation environment for NG eCall. Keysight provided the network and RF test capability, while HEAD acoustics contributed the acoustic validation environment needed to assess voice and audio behavior. This combination addressed a core requirement for emergency call systems: communication must work at both the network layer and the human voice interaction layer.
