en.Wedoany.com Reported - Keysight Technologies, a U.S. test and measurement company, recently announced that its Hybrid eCall test solution has received certification from DEKRA based on the EN 18052:2025 standard. This certification targets emergency communication systems for connected vehicles, covering end-to-end testing requirements between in-vehicle systems, mobile networks, and public safety answering points. It provides automakers with a compliance verification tool as 2G and 3G networks are gradually phased out and 4G and 5G networks take over emergency communication services.
Connected vehicles are entering a more complex phase of communication transition. In the past, automotive emergency call systems primarily relied on traditional cellular networks and circuit-switched voice capabilities for accident alerts, location data transmission, and rescue call connections. However, mobile operators in Europe and globally are gradually shutting down 2G and 3G networks, forcing automakers to adapt in-vehicle emergency communication systems to new-generation packet-switched networks. Next-Generation eCall needs to leverage 4G and 5G networks for emergency calls, minimum set of data transmission, voice connectivity, and network fallback capabilities. Yet, the pace of network upgrades varies across regions, meaning the same vehicle model may encounter traditional networks, next-generation networks, and hybrid coverage environments in different countries and under different operator networks. The Hybrid eCall solution certified by Keysight specifically addresses the testing challenge of "reliable triggering, accurate transmission, and stable connectivity in hybrid networks." For automakers, connected vehicles are no longer just about adding navigation, entertainment, and remote diagnostics; emergency communication has become part of the vehicle's safety architecture. Testing and verification must cover signaling, voice, location, telemetry, and fallback processes under real network conditions. DEKRA certification indicates that the solution has been validated against the EN 18052:2025 standard, helping reduce uncertainties for automakers in emergency communication system integration, regulatory adaptation, and cross-regional delivery.
Key scenarios covered by the certification include emergency call setup, minimum set of data transmission, voice communication quality, and network fallback capabilities, with test targets spanning in-vehicle systems, mobile networks, and public safety answering points.
The industrial value of such connected vehicle testing capabilities is concentrated at the intersection of automotive safety regulations and communication infrastructure upgrades. As smart vehicles, software-defined vehicles, and cross-border vehicle platforms accelerate in adoption, automakers need to complete communication compliance testing for different markets within shorter development cycles, while ensuring that vehicles can accurately transmit location and vehicle status data to rescue systems in the event of an accident. If emergency communication systems malfunction during 2G/3G network phase-outs, uneven 4G/5G coverage, or network handovers, it could directly impact accident response efficiency and increase certification pressure for vehicle platforms entering Europe and other highly regulated markets. The Hybrid eCall test solution integrates in-vehicle terminals, mobile networks, and public safety answering points into a single verification chain, helping shift testing from traditional lab-based single-point tests to end-to-end, real-network-oriented system verification. For suppliers of communication equipment, in-vehicle modules, T-Boxes, vehicle electronic and electrical architectures, and public safety platforms, the upgrade of connected vehicle emergency communications will also drive demand for test instruments, protocol conformance, interoperability verification, and field network simulation. These capabilities will become foundational elements in the export of smart vehicles and the development of global vehicle platforms.
Keysight also plans to showcase its Hybrid eCall and NG-eCall testing capabilities at the ETSI NG-eCall Plugtests 2026. This event will bring together automakers, suppliers, network operators, and emergency service stakeholders to verify multi-vendor interoperability on commercial infrastructure. As the scale of connected vehicles grows, emergency communications, connected vehicle technologies, and 4G/5G hybrid network adaptation will continue to be key focus areas at the intersection of automotive electronics and the information and communication technology industry.
