Benchmarking Cellular Wireless Connectivity in Railway Scenarios
ScenarioSketch

“The increasing demand for reliable and high-speed wireless connectivity in railway transportation has driven research into optimizing mobile network performance in train environments.” This dissertation presents a comprehensive benchmarking methodology for evaluating cellular network performance on moving trains, addressing the unique challenges posed by high mobility, vehicle penetration loss, and trackside infrastructure limitations.

A structured approach is developed for data collection, processing, and analysis, utilizing controlled measurement campaigns on various train types. Network key performance indicators are examined to assess the impact of train design, network infrastructure, and environmental factors on connectivity.

Furthermore, the study compares different onboard connectivity enhancement solutions, such as repeater systems and frequency-selective surface window coatings, analyzing their effectiveness in mitigating signal attenuation. Advanced statistical methods and geospatial modeling techniques are applied to improve measurement strategies and ensure accurate evaluations. Additionally, this research integrates the digital twin concept by modeling railway environments, cellular network deployments and train properties in a virtual framework. This approach enables a comprehensive evaluation and optimization of mobile connectivity onboard trains.

The findings contribute to a better understanding of mobile network performance in railway scenarios and provide insights for optimizing future deployments. The methodologies developed in this thesis can serve as a foundation for railway operators and mobile network providers to enhance passenger connectivity and operational efficiency.”
