Wireless Communication Systems for Urban Transport

Abstract

This chaptκr dκscribκs thκ main λκaturκs oλ thκ wirκlκss communication systκms oλ urban rail and rκlatκd applications. Thκ pκrspκctivκ will bκ complκtκ: application, nκtwork and physical layκrs will bκ discussκd. Morκovκr, to propκrly addrκss somκ oλ thκ challκngκs that thκsκ systκms λacκ, wκ will providκ a dκκp insight into propagation issuκs rκlatκd to tunnκls and urban arκas. Finally, a dκtailκd survκy on thκ dirκctions oλ rκsκarch on all thκsκ topics will bκ providκd.

Novel technology concepts and architecture for on-board condition-based monitoring of railway running gear: The RUN2Rail vision

“…For the T2G communications the most common technology choice is the public 3G–4G network but many operators are starting to deploy private T2G networks based on IEEE 802.11 or even 4G private networks. 11 The use of the railway standard GSM-R is not very common because any new interface requires an update in the safety case, which is expensive. On the other hand, GSM-R is not IP-based so flexibility is not its strength.…”

“…Depending on their location or purpose, wireless communication systems implemented on trains can be divided into three main scenarios: train-to-ground (T2G), inter-car and intracar. For the T2G communications the most common technology choice is the public 3G-4G network but many operators are starting to deploy private T2G networks based on IEEE 802.11 or even 4G private networks [13]. The use of the railway standard GSM-R is not very common because any new interface requires an update in the safety case, which is expensive.…”
