MEASUREMENT ANALYSIS FOR HANDOVER INITIATION PROCEDURE IN A HIGH SPEED TRAIN ENVIRONMENT

High speed train has been the most prominent transportation that been used by the public to save the travel time due to the road congestion especially during the peak hour. Most of people travel by trains for about forty to fifty minutes to reach their destination. In parallel with the development of high speed trains nowadays as the trains’ speed can reach up to 350km/h, there have been extensive researches to improve the data rates for mobile wireless communication. Higher data rate and reliable mobile communication are desirable when moving in high speed trains. The passengers on board usually play online application, surf internet, check emails, reading books and many more to kill time. As a solution, the latest LTE system seems to be a convincing platform to provide high data rates since it is expected to support high peak data rates of 1Gbps in downlink for low mobility and up to 100Mbps in high mobility environment. This paper provides the measurement analysis of current deployed network along high speed rail road. The results in this paper will be the pilot parameter to be analyzed further in order to improve mobile communication handover performance for high speed trains in LTE system.
