Anritsu has launched an advanced acoustic evaluation solution for next-generation automotive emergency call systems developed in collaboration with Head Acoustics, a global leader in acoustic measurement and analysis.
The solution, which is compliant with ITU-T Recommendation P.1140, enables precise assessment of voice communication quality between vehicle occupants and public safety answering points (PSAPs), supporting faster and more effective emergency response.
With NG eCall over 4G (LTE) and 5G (NR) now mandatory in Europe as of January 1, 2026, ensuring high-quality, low-latency voice communication during vehicle emergencies has become essential. After a collision, calls are conducted hands-free inside the vehicle cabin, where high noise levels, echoes and other acoustic challenges can significantly degrade speech clarity. Reliable voice performance is therefore critical to accurately conveying the situation and enabling rapid rescue operations.
The solution integrates Anritsu’s MD8475B (for 4G LTE base-station simulation) or MT8000A (for both 4G LTE and 5G NR simulation) with Head Acoustics’ Acqua voice quality analysis platform. This combination enables comprehensive evaluation of transmitted (microphone) and received (speaker) audio under a wide range of realistic operating conditions.
