This position is part of the Marie-Curie Doctoral Network (EU MSCA project Mobile and Optical Networks for 6G (MONET-6G)).

• You will investigate next-generation fiber-wireless architectures for indoor settings, such as Fiber-to-the-Room (FttR) for Wi-Fi and LiFi. That includes:

• Identify promising in-building use cases (communication, positioning, sensing) for industrial, medical, home, and enterprise scenarios.

• Compare point-to-point (P2P) and point-to-multipoint (P2MP) fiber architectures for Wi-Fi and LiFi.

• Evaluate integrated fiber-wireless solutions across various deployment scenarios.

• Evolve existing in-building fiber and wireless technologies to achieve adequate performance at a reasonable cost.

• Set up a simulation framework based on experimentally validated models.

• Conduct systematic performance evaluations to identify a best-practice approach.

• Demonstrate key features of the proposed architecture in a laboratory setup.

What you contribute

• Outstanding scientific Master's degree in electrical, electronics, telecommunications, photonics, microwaves engineering, physics or similar

• Knowledge of simulation tools for communication systems, digital signal processing; experience in MATLAB/Python.

• Theoretical and experimental knowledge of optical and electrical communication systems

• Professional commitment

• Team spirit, ability to work independently and autonomously

• Previous publication experience is an advantage

What we offer

• Fascinating challenges in a scientific and entrepreneurial setting

• 30 vacation days

• Modern and excellently equipped workspace in a central location

• Great and cooperative working atmosphere in an international team

• Flexible working hours

• Support if you wish to do a doctorate

• Opportunities to work from home

• Extensive training-, health- and sports offers
