Abstract
During the last years, the application of different wireless technologies has been explored in order to enable Internet connectivity from vehicles. In addition, the widespread adoption of smartphones by citizens represents a great opportunity to integrate such nomadic devices inside vehicles in order to provide new and personalized on trip services for passengers. In this paper, a proposal of communication architecture to provide the ubiquitous connectivity needed to enhance the smart train concept is presented and preliminarily tested. It combines an intra-wagon communication system based on nomadic devices connected through a Bluetooth Piconet Network with a highly innovative train-to-ground communication system. In order to validate this communication solution, several tests and simulations have been performed and their results are described in this paper.
Highlights
The companies that offer transportation services are increasingly interested in enabling remote communications with their fleet by using wireless technologies
If the bandwidth requested for communications is higher than the available bandwidth in the access network selected by the system as active, the middleware selects which requests are more critical, and pauses those that it assumes less critical until conditions change and they can be attended to
A transmitter antenna, connected to a signal generator at 2.4 GHz has been located at the coordinates (X = 14.8 m, Y = 1.25 m, Z = 1.1 m) which correspond with the final part of the wagon train, with a transmission power of −10 dBm
Summary
The companies that offer transportation services are increasingly interested in enabling remote communications with their fleet by using wireless technologies These connectivity systems allow them to improve their daily work (by means of new services like fleet management, operation monitoring, safety related applications, vehicle maintenance or/and diagnostics, and so on) and the services provided to the transportation service users. The innovation of this work is to enhance the concept of ubiquitous connected smart train by contributing with advances in train-to-ground wireless communication systems [1] and taking advantage of the communication and interaction possibilities of smartphones for communications inside the train The combination of these two challenges, an intra-train communication system based on nomadic devices and a highly innovative train-to-ground communication system, will be capable of improving user experience of passengers who could enjoy more customized information
