A Satellite-Based Infrastructure Providing Broadband IP Services on Board High Speed Trains
نویسندگان
چکیده
After the earlier technologies that offered satellite mobile services for civil and military applications, today’s specific antenna design, modulation techniques and most powerful new generation satellites also allow a good level of performance to be achieved onboard high speed modes of transport such as aircraft and trains. This paper reports the Eutelsat’s experience in the developing and deploying architecture based on a spread spectrum system in order to provide broadband connectivity on board of high speed trains. After introducing the adopted technologies, the architecture and the constraints, some results obtained from analysis, testing and measuring of the availability of the service are reported and commented upon.
