Anritsu Corporation has launched an evaluation solution for the “Hybrid eCall,” an advanced automotive emergency call system, marking an industry first. Hybrid eCall seamlessly integrates high-speed 4G (LTE) communications with conventional 2G (GSM/GPRS) and 3G (W-CDMA) networks, ensuring uninterrupted emergency connectivity regardless of location. This solution facilitates the efficient and reliable development of Hybrid eCall-compatible vehicles by automotive manufacturers.
Why Hybrid eCall Matters
The eCall system automatically initiates emergency rescue requests in the event of a collision. When onboard sensors detect an accident, the In-Vehicle System (IVS) transmits location and vehicle data to the Public Safety Answering Point (PSAP). Operators then use this information to dispatch rapid rescue services.
While conventional eCall primarily used 2G/3G networks, Next Generation (NG) eCall over 4G is increasingly widespread. It supports faster and more stable communication than its predecessor and offers advanced features such as transmitting accident scene footage. The EU plans to mandate NG eCall starting January 1, 2026, making compliance an urgent priority for automotive manufacturers.
However, conventional eCall is still necessary in areas without 4G coverage. Consequently, Hybrid eCall technology—which switches between NG eCall and eCall based on network availability—is critical. Supporting Hybrid eCall ensures reliable emergency call services anywhere, making it essential for automotive manufacturers.
