Applications of machine learning in radio-wave propagation prediction

​​​​​​​​​​​​​​​​​​​​​

​​​​​​​​​​​​​​​​​The International Telecommunication Union (ITU) organizes the ITU-R Workshop on “Applications of machine learning in radio-wave propagation prediction”, which will take place in Geneva, Switzerland, on 27 May 2025 from 0900 to 123​0 hours (CEST). Remote participation will be provided for this workshop.​

The objective of the workshop is to consider and discuss machine learning (ML) as applied in modelling radio-wave propagation prediction, as well as its use in developing models of parameters or phenomena relevant in the prediction of radio-wave propagation. In the context of ITU, radio-wave propagation prediction models find application in spectrum sharing and compatibility studies, international coordination of spectrum use and the design of national telecommunication networks. This workshop will bring together experts in radio-wave propagation as well as experts in machine learning to explore how new approaches of machine learning could be applied to radio-wave propagation modelling and address challenges that could arise.  Such challenges could include:

• Modelling of key propagation phenomena and parameters;
• The need to process very large volumes of data from different sources;
• Uncertainty within the training data;
• Model explainability.​
