"Cellular Network Quality Improvements for High Speed Train Passengers by on-board Amplify-and-Forward Relays";
Talk: 13th International Symposium on Wireless Communication Systems (ISWCS 2016), Poland; 09-20-2016 - 09-23-2016; in: "13th International Symposium on Wireless Communication Systems", IEEE Xplore, Poznan, Poland (2016), ISBN: 978-1-5090-2061-4; 325 - 329.

In this paper, we evaluate the impact of moving cells
for various cellular network services and User Equipments (UEs).
We conduct measurements and analyze parameters such as RSCP
and RSRP, as well as application data rate. Coverage can be
significantly improved for High Speed Train (HST) passengers,
differently in context of space diversity. The measurements are
conducted from December 2015 to April 2016 along railroad
from Vienna to Salzburg. We show that there is performance
improvement when employing two amplify-and-forward Moving
Relay Nodes (MRNs) onboard the HST compared to direct
transmission from macro sites. To tackle with high Vehicular
Penetration Loss (VPL), unpredictable and unstable throughput,
and worst case scenario onboard the HST, we investigate network
performance based on descriptive statistics.
