Rohde & Schwarz has cleared a major milestone as the company announces that it hybrid eCall and Next Generation eCall test solution has successfully passed certification testing by cetecom advanced, a leading independent lab trusted for global product certification across communications, automotive, medical, payment, and identification technologies.
The solution is built on Rohde & Schwarz’s CMX500 radio communication tester, now upgraded with an updated eCall option that ensures compliance with the latest eCall regulations and standards.
Under the hybrid eCall test specification EN 18052, a hybrid system must use multiple transmission paths and protocols to guarantee an eCall reaches its destination reliably. In real world terms, this means a vehicle uses NG eCall functions (IP/IMS based voice and data over 4G/5G) but automatically falls back to classic CS eCall (2G/3G) when coverage or service quality drops.
Manufacturers must validate that their hybrid implementations can trigger calls, transmit the minimum set of data (MSD), maintain GNSS positioning, and deliver clear voice quality across multiple network scenarios.
This includes Voice over New Radio (VoNR), Voice over LTE (VoLTE), and circuit switched fallback. Tests must also prove the system stays robust during handovers and under degraded radio conditions, while meeting CEN, ETSI, 3GPP, and national requirements.
Rohde & Schwarz has updated its eCall evaluation solution, CMX-KA09x, to support compliance with EN 18052:2025 and EN 17240:2024+A1:2026.
The CMX-KA099 option passed Public Safety Answering Point (PSAP) test scenarios per EN 18052:2025, while CMX-KA098 passed PSAP scenarios per EN 17240:2024+A1:2026. This is a critical step toward meeting European requirements for NG eCall test systems.
Through this collaboration, Rohde & Schwarz and cetecom advanced are helping the automotive industry accelerate adoption of next generation vehicle communications that put safety first.
Leadership Comment
“We use the solution for functional tests and protocol conformity tests as well as for the type-approval of In-Vehicle Systems (IVS) that implement hybrid eCall and NG eCall,” says Thomas Reschka, Senior Technical Consultant at cetecom advanced. “The test environment allows the simulation of real-world mobile network conditions and the emulation of various network scenarios. This is a significant advantage in preparing for certifications or the market launch of new vehicle models.”
