Railways Networks - Challenges for IoT Underground Wireless Communications

Abstract

The use of wireless network technologies for the deployment of data communications systems in railway transportation infrastructure and services is essential. In fact, wireless solution for railways, especially for underground, is a big challenge to operators concerning this environment particularities. Many technologies were pointed as promising candidates for the future railway mobile telecommunications but, in reality, no current technology features overall appropriated. This paper discusses a Practical Guidance based on challenges for IoT wireless networks, based on a conventional Wi-Fi network case study. Moreover, it also highlights topics where new intelligent networking technologies, emerging from Internet of Things (IoT) paradigm, can contribute significantly to the improvement of railway networks.
