Acoustic Evaluation Platform Validates Emergency Call Systems
To help ensure reliable voice communications in next-generation automotive emergency call systems (NG eCall), Anritsu collaborated with HEAD acoustics to launch an advanced acoustic evaluation solution. Compliant with ITU-T Recommendation P.1140, it enables validation of the voice communication quality between vehicle occupants and Public Safety Answering Points (PSAP), for faster and more effective emergency response.
Now mandatory in Europe as of January 1, 2026, NG eCall over 4G (LTE) and 5G (NR) provides voice communication during vehicle emergencies hands-free inside the vehicle,
where high noise levels, echoes, and other acoustic challenges can significantly degrade
speech clarity.
The solution integrates Anritsu’s MD8475B (for 4G LTE base-station simulation) or MT8000A (for both 4G LTE and 5G NR simulation) in conjunction with the HEAD acoustics ACQUA voice quality analysis platform. The combination offers comprehensive evaluation of transmitted (microphone) and received (speaker) audio under a variety of realistic operating conditions.
