On-board wireless telecommunications in railways operate in a challenging environment including rapidly fading radio channels and various sources of statistically variable interference. These conditions hamper seamless, high-rate data transmission by making fast handovers to ground base stations difficult. This paper addresses networking techniques wireless communication in trains by presenting a technical overview of wireless communications options and reporting field experiments using Flash-orthogonal frequency division modulation (OFDM) technology. The research is based on in vivo measurements recorded in high-speed Pendolino-trains in Finland. The results indicate that Flash-OFDM technology fulfils the coverage and service accessibility requirements for high-rate interactive multi-media services with respect to latency and data rate, provided that loading of the Flash-OFDM network due to other users remains low.

“…In fact, the effective delay is likely to exceed 600 ms if the satellite link is used together with the GPRS return channel thus hindering most of the convenient two-way, real-time communications. In Finland, low positioning of satellites in geosynchronous orbit also seriously limits link availability [16].…”

“…The broadband satellite networks were discussed in [3] where the integration to the terrestrial network is seen as a challenge. The use of the third generation partnership project (3GPP) LTE air interface in satellite communications was evaluated in [4] where it was found that the existing terrestrial air interface can be used with some adjustments.…”

The impact of the terrestrial network interference to a satellite uplink transmission is studied in this paper. In a system, where an LTE terrestrial network is extended by a satellite communication, the terrestrial interference can become a problem. The interference levels are studied via infield measurements and link budget calculations and the interference tolerance of the satellite receiver are studied via computer simulations. The results show that in spite of the long satellite communication link, strictly power limited system and terrestrial interference the satellite link can operate on the same frequency band as the terrestrial network.

“…Therefore their adaptation for the provision of media rich or conversational applications, at the quality requirements set by terrestrial networks, is not easy. One of the main issues identified also in [1] is the dynamic and efficient allocation of resources, optimized for packet loss and delay.…”
