SegHyPer: Segmentation- and hypothesis based network performance evaluation for high speed train users

Abstract

Two solutions are presented to overcome the coverage and low bit rate problems for cellular network services in high mobility: amplify-and-forward Moving Relay Nodes (MRNs) and prototype windows on-board Wi-Fi enabled High Speed Trains (HSTs). This paper focuses on 3G/4G User Equipments (UEs) located on-board the high Vehicular Penetration Loss (VPL) vehicles travelling throughout long-range geographical routes. This work is supported by extensive real-world measurements conducted along Austrian railways such as from Vienna to Salzburg and from Vienna to Graz. We propose a novelistic approach and we call SegHyPer. The approach is established by multi-level non-parametric hypotheses tests based on route segmentation link quality parameters to enable micro-analysis in current and future cellular networks for mobile users on-board railjet HST with- and without treatment.
