According to the ‘DB
Mobile’ magazine 9/2006, the Deutsche Bahn (German railways) is about to retrofit their
high speed trains with power sockets at each seat. Great news for people like
me and others who prefer the train and who previously had to struggle for seats
near power sockets to get some work done while on the go. All high speed trains
are also already equipped with GSM repeaters so coverage inside the train for the
mobile Internet is usually excellent. So Deutsche Bahn, when you do the
retrofit, don’t forget to add UMTS repeaters.

How do these GSM repeaters inside train carriages work — i.e. what do they use as the backhaul?
Hi James,
They are just layer one repeaters that picks up and amplify the signal from GSM base stations along the track.
Cheers,
