The development environment for the connectivity system of tomorrow

The "digital twin" as an image of an increasingly complex radio environment

The vehicle of the future is digital and connected. Automated driving and entertainment applications used in parallel are setting increasingly complex demands on modern connectivity systems. To ensure the reliability of these systems and at the same time improve their performance, a wide range of measurement and testing procedures is required. Today, these tests are complex, time-consuming and expensive. Nevertheless, they deliver incomplete and hardly reproducible results.

The DOCT research project aims to significantly increase the safety of in-vehicle connectivity systems by creating a high-performance development environment. A fast and nearly complete qualification of secure and robust radio systems for automated driving and OTA data applications will thus become possible.

The "digital twin" is the image of a radio scenario portfolio optimized for the project and thus of the complex radio environment. This portfolio is composed of the radio scenarios of the partners, which are redundancy-filtered by AI methods and completed by extrapolation in frequencies and modulation standards. The "digital twin" is then tested and evaluated in a measurement chamber on the vehicle as part of a proof-of-concept.

DOCT closes the gaps for a complete test pattern

DOCT makes the high complexity manageable

DOCT reduces the test- / measurement effort

DOCT creates the basis for standardization of the test procedures


As a broad-based interdisciplinary team from business and research entities, we are developing, together within DOCT, the development environment for connectivity systems of tomorrow.

2nd DOCT project meeting in Regensburg at Continental

Berlin, December 2022 - The DOCT consortium gathered at Continental in Regensburg for a second project meeting on December 07 and 08, 2022. Approximately 30 participants gathered to discuss current progress and the next steps towards the development environment for the connectivity system of tomorrow.

DOCT kick-off at Rohde & Schwarz in Munich

Berlin, July 2022 - The DOCT consortium gathered in Munich at Rohde und Schwarz on July 5 and 6, 2022, to launch the three-year DOCT (Digital OTA Connectivity Twin) project. More than 30 people attended the meeting and committed to the task of jointly defining the development environment for tomorrow's connectivity system.
