Abstract:
In this paper, we investigate the systematic change in the signal quality of mobile telecommunication systems inside a high-speed train. Using commercial mobile phones, we perform measurements inside a carriage of a high-speed train with an installed repeater and inside a carriage of a different high-speed train equipped with low radio frequency attenuation windows. We carry out additional reference measurements inside regular carriages of a high speed train. We use the adjusted Harrell-Davis method and the nonparametric bootstrap to test multiple quantiles of samples from the key performance indicators produced by the commercial mobile phones. In addition, we propose a common framework to standardize future comparisons on such studies. The results confirm considerable improvements in signal quality resulting from both the repeater and low RF attenuation windows.
