Jan Plachy received the BSc, MSc and Ph.D. degree in telecommunication engineering from the Czech Technical University in Prague, Czech Republic in 2012, 2014 and 2021, respectively. Currently, he works as a part time researcher at the Department of Telecommunication Engineering at the same university, while managing the 6Gmobile research lab testbed where he prepares demos to demonstrate the research done within the 6Gm lab. Furthermore, he primarily works as R&D Technical Product Manager at Deutsche Telekom in T-labs Berlin focusing on future networks research. From 2022 he participates in research towards 6G in the next Generation Research Group within the O-RAN alliance and co-leads one of the research streams. He was on internships at CEA-Leti, France (2014), EURECOM, France (2016 and 2019) and Bar-Ilan University, Israel (2017). He has been participating in many national (Czech and German) and international research projects focused on mobile networks. His research interests cover optimization of mobility management and radio resource management of both communication and computing resources, non-terrestrial communication, and joint communication and sensing. He published 14 conference and journal papers in IEEE and Elsevier.

Publications, patents, and demos

Jan is author of more than 10 papers at international conferences and in peer-reviewed journals and multiple demos.
Selected publications


  • Channel quality prediction via Deep Neural Network
    • This demo shows prediction of channel quality between any two devices from already known channels to base stations
    • The demo consists of three parts:
      • Open Air Interface RAN modifications to enable obtaining frequent channel quality measurements from both serving and neighboring cells and their collection.
      • Android application for collecting measurements and visualization of the predicted channel quality.
      • Python server application that collects measurements from Android application, trains neural network and predicts the communication channel quality
    • Implementation of all parts done by Jan Plachy.
    • Role: Design of demo, implementation of all parts.

  • Flying base station
    • Based on work of lab members in area of exploitation of flying base stations for providing wireless connectivity to mobile users, we have developed an actual flying base station.
      • The flying base station is equipped with an Intel NUC PC that runs the OAI RAN, LTE USB dongle for connection to “base camp station” and USRP B205 mini with antennas. OAI Core network is run in the base camp station.
    • A demonstration of initial flight is shown here.
