This master thesis aims to interconnect two wireless networks running on different
standards. The solution is tailored to the environment of rail transport, where
one network connects the wagons of the train and thereby a number of radios
enabling landside interaction. It aims to provide a fallback link for the ever more
important radio connection of trains operating in the network. The railways unique
properties, like the length of the train and its adherence to tracks, where each wagon
passes the same locations after some delay, are exploited to develop an adapted
solution. IPv6 over Time Slotted Channel Hopping (6TiSCH) is proposed as an on-
train networking stack to connect low power nodes in each wagon. Digital Enhanced
Cordless Telecommunications New Radio (DECT NR+) is introduced as a candidate
technology to connect the train with landside radio towers. First experiments to use
DECT NR+ in a moving reference frame are conducted. A 6TiSCH implementation
is adapted to trigger external resources based on its Time Slotted Channel Hopping
(TSCH) slot timing. This is successfully used to trigger transmissions of messages
such that a trains multiple DECT NR+ radios could be orchestrated to act in unison.
