Performance measurement of the LTE signal strength along Osaka – Yokohama railway using Tokaido Shinkansen high speed train: article / Dulisyahila Gulamsarwar

The use of high-speed train has progressively increased over the past years and it has become the most important public transportation. With the rapid development of mobile communication, mobile telephone users are expecting higher network capacity and good connection quality. In that case, passengers are demanding a high quality of voice and data-rich communication. The main objective of this research is to study the performance of LTE in a high-speed railway from Yokohama to Osaka using a commercial measurement tool namely Nemo handy. The data collected from the measurement has been analysed using a software named Nemo Analyzer. The measurement analysis of the currently deployed LTE network is being done at the velocity of up to 300km/h. The measurements works were conducted in the morning, evening and night on six fine days. The results yields some useful information which is the SNR and RSRP are proportional to each other and the signal strength is proportional to the speeds. At last, this studies inferred that the speed of the train may affect the quality of the signal strength.
