The future development of the railway is
highly desired to evolve into a new era where
infrastructure, trains, travelers, and goods will be
increasingly interconnected to provide high comfort,
with optimized door-to-door mobility at
higher safety. For this vision, it is required to
realize seamless high data rate wireless connectivity
for railways. To improve the safety and
comfort of future railways, wireless communications
for railways are required to evolve from
only voice and traditional train control signaling
services to various high data rate services including
critical high-definition (HD) video and other
more bandwidth-intensive passenger services,
such as onboard and wayside HD video surveillance,
onboard real-time high data rate services,
train multimedia dispatching video streaming,
railway mobile ticketing, and the Internet of
Things for railways. Corresponding mobile communications
network architecture under various
railway scenarios including inter-car, intra-car,
inside station, train-to-infrastructure and infrastructure-
to-infrastructure are proposed in this
article. Wireless coverage based on massive
MIMO for railway stations and train cars is proposed
to fulfill the requirement of high-data-rate
and high spectrum efficiency. The technical challenges
brought by the massive MIMO technique
are discussed as well.
