ei Future-Oriented LTE for Rail Solution
With the rapid development of railway transport,
simple voice and constraint data services can not
satisfy the high-speed data requirements both
from train operators and from passengers. For
train operators, a more efficient way to guarantee
train operational safety and on board security is
becoming more and more important. Services such
as on board broadband video service are beyond
the reach of GSM-R but are readily available
on Huawei’s LTE solution. For the passengers,
many people are enthusiastic about using mobile
broadband services while on the move with
laptops, mobile phones and cloud computing
devices. Many business travelers today have the
ability to connect to their work space from outside
the office. Continue working while travelling allows
travel time to be converted into productive working
hours. With the understanding of rail operational
Huawei eWBB LTE solution can support broadband service

demands as well as rail passenger communication
demands, Huawei eWBB LTE solution is designed
to providing broadband services that are far
exceeding capabilities of standard GSM-R. Video
surveillance solutions implemented on board,
along the track or on platforms help to further
improve Railway services and customer satisfaction
by allowing centralized security staff to monitor
situation on individual trains. At the same time the
system can be configured to deliver broadband
wireless connectivity to passengers allowing them
to access up to date travel information, access
internet services during the trip or watch real-time
TV. With its wide portfolio, Huawei is the right
partner for railways to pull all these technologies
together into one Smart Railway solution allowing
railways to focus on passenger needs and railway
operational demands.
Current Communication Service Requirements for Railway Industry
Huawei eWBB LTE solution permits railways to
establish high speed Broadband Data connections
on board the train. As for GSM-R, LTE based
eWBB includes specifically designed algorithms
to deliver superior Quality of Services at highest
train speeds. Huawei’s solution has been tested
at speeds of 430km/h on Shanghai’s Maglev
line. Based on LTE technology, Huawei’s solution
on maglev with FDD 20MHz, 2 × 2 MIMO
configuration, the Peak downlink rate can reach
50Mbps. With its flat network architecture eWBB
is a cost efficient solution delivering shortest bit
transfer delays. Overall reliability of the system is

eWBB solution is considered the most advanced
rail telecommunication solution merging synergies
between GSM-R operation, non safety critical rail
operational voice and data services and passenger
communication.

CCTV cameras installed along the track provide
video feeds from trackside, platforms or specific
hot spots such as level crossings. This information
is fed into centralized control centers, stored in
Huawei’s data cloud solution, processed by our
video analysis software and transmitted via eWBB
into the train or played back for analysis. This
implementation allows ground based staff as well
as staff on board the train to have visibility well
ahead of the train. In connection with eWBB,
cameras can also be installed inside the carriage
allowing surveillance inside the coach through
centralized ground based staff or mobile security
units along the line. Huawei’s CCTV solution
allows real time video analysis and storage of video
streams in Huawei’s Data Centre solution for post
incident analysis.

Synchronization of locomotives
Our customer awarded Huawei to help them with
a solution to double their actual cargo capacity
in order to meet a targeted 350 million tons
transportation capacity per year. Our solution helps
the operator to reach their targets by providing
multi-locomotive synchronization control command
transmission, substantially enhancing the carrying
capacity of each train. In order to meet the
operational demands, both traditional data service
and broadband service were offered.

Board Level Redundancy:
One RRU can be connected with two LBBP (LTE
Baseband Processing) boards working in a local
redundancy mode. In case functions on one LBBP
board fail, services are automatically provided
through the redundant board.
Huawei’s eCNS600 main board supports 1+1
standby mode ensuring highest reliability figures.
Network Element Backup:
Huawei’s railway solutions support 1 +1 core
network redundancy through geographical
redundant nodes. For an example one eNodeB
connects to two eCNS and one eCNS connects two
PTT servers further improving the overall system
reliability.
Redundancy of the radio coverage is critically
important for railway operation. For this reason
Huawei introduced the unique concept of a Master
eNodeB and a Slave eNodeB. The eNodeB’s are
deployed along the track to provide redundant
coverage. Without manual intervention the slave
eNodeB will take over from the master eNodeB
in case of loss of function (i.e. fire, flood..) of the
master eNodeB.
