The TCU is an embedded central communication hub that wirelessly connects a vehicle with external networks, such as cloud services or V2X communication systems. Integrating multiple wireless standards – including LTE, 5G, NTN and GNSS – it supports essential functions such as emergency call (eCall), advanced driver assistance (ADAS), fleet management, over-the-air software updates and remote diagnostics.
In the lab, TCUs are validated for protocol compliance, connectivity performance, and GNSS accuracy, while automated production tests ensure consistent quality and reliable operation of all mechanical, electrical, and software components with highest throughput.
Vehicle manufacturers are integrating more and more wireless connectivity to enable new user experiences and services. Our test solutions cover all wireless technologies used in the automotive industry from 5G and ultra-wideband to eCall and GNSS. They allow antennas and wireless modules to be thoroughly tested on a RF and functional level to ensure the required sensitivity and throughput and seamlessly transition from lab to mass production.
We empower chip suppliers, module makers, Tier 1 suppliers, and OEMs to deliver safe, efficient, and future-ready connected mobility solutions.
