Key facts

Investigate narrowband IoT (NB-IoT) radio access network (RAN) access and transmission procedures compatible with 3GPP standards, operating within the context of moderate LEO satellite constellations.
The central objective is to design and evaluate 3GPP protocol adaptations that achieve high energy efficiency in the satellite access.
Develop a solid theoretical foundation covering LEO satellite systems and constellation design, as well as the fundamental principles of 3GPP access procedures.
Study of NB-IoT transmission under moderate LEO constellations, where the constellation geometry imposes specific constraints on the PHY and MAC layers that 3GPP procedures.
The practical work will be carried out in simulation environments, where NB-IoT transmission scenarios under moderate LEO constellations will be modeled and analyzed. The resulting protocol solutions will be evaluated against key performance metrics.

DLR stands for diversity, appreciation and equality for all people. We promote independent work and the individual development of our employees both personally and professionally. To this end, we offer numerous training and development opportunities. Equal opportunities are of particular importance to us, which is why we want to increase the proportion of women in science and management in particular. Applicants with severe disabilities will be given preference if they are qualified.
