Packet error rate measurement using IEEE 802.15.4-based modem on the Korea high-speed train

摘要

In this paper, the performance of an IEEE 802.15.4 based modem designed to monitor the state of underbody parts related to the security of high speed trains is investigated. Based on the intensive field tests, the optimum positions of transmitter and receiver within the high speed train are proposed. The validities of the proposed scheme is verified with packet error rate (PER) measured at the several points of high speed trains.
