BANGKOK, May 13, 2022 /PRNewswire=KYODO JBN/ --

The Huawei Global Rail Summit 2022 was successfully held during the Asia

Pacific Rail 2022 in Bangkok, Thailand. This prestigious event brings together

thought leaders, futurists, and key stakeholders from the global rail industry

to share insights into industry trends and best practices around digital

transformation.

The rail industry aspires to build securer, smarter, more convenient, more

efficient, and greener urban rail, which places higher requirements on

networks. However, today's urban rail networks suffer from low Wi-Fi bandwidth

for train-to-ground service backhaul, frequent loss of real-time data, and low

installation and deployment efficiency. This makes it impossible to achieve

real-time backhaul of all typical bandwidth-hungry services such as passenger

information system (PIS).

Xiang Xi, Vice President of the Global Transportation Business Unit, Huawei's

Enterprise Business Group, shed some light on Huawei's innovative Wi-Fi 6

solution for train-to-ground communications in his keynote speech titled

"Driving Digitalization in Future Rail to Create New Value Together".

"Huawei's Wi-Fi 6 Train-to-Ground Communications Solution draws on many

technological innovations to achieve up to 1.4 Gbit/s bandwidth for real-time

service transmission when trains are running at a speed of 160 km/h," said

Xiang Xi. "It also ensures zero service interruptions by slashing the network

handover latency for train-to-ground communications to less than 30 ms. Beyond

that, the all-in-one integrated chassis is easy to deploy, shortening the

installation period by 67%. Ultimately, this results in stable operations of

urban rail."

Huawei's Wi-Fi 6 Train-to-Ground Communications Solution has proven highly

valuable in Shenzhen Metro's Line 20. Equipped with Huawei's solution, Shenzhen

Metro's Line 20 builds industry-leading commercial Wi-Fi 6 connectivity for

train-to-ground communications, and benefits from always-on, large-bandwidth,

and low-latency backhaul of all services needed for autonomous driving urban

rail. In turn, this delivers all-new safe travel experience for passengers

through smart urban rail.

Huawei showcased a full suite of innovative rail transport solutions and

flagship products at the Huawei Global Rail Summit 2022. In particular,

Huawei's innovative low-carbon intelligent campus network solution for station

campuses took the spotlight. This ground-breaking solution stands out with an

all-new simplified network architecture, plug-and-play remote units (RUs), and

green, energy-saving design. Such powerful capabilities allow the network to

stay ahead in the sustainable development of station services.

The compelling benefits of this solution include:

-Simplified architecture with "one device, one network": The innovative

simplified network architecture consists of the central switch and RUs, with

RUs serving as the extended ports of the central switch and deployed onto

desktops. This ensures all terminals can access the network through nearby RUs,

in turn minimizing cabling from the extra-low voltage (ELV) room to terminals.

-Always-on services and smooth network evolution: By leveraging the

industry-leading optical-electrical PoE technology, the central switch can

supply PoE++ (60 W) to RUs at ultra-long distances of 300 m. This eliminates

the need of ELV boxes and cabinets and effectively addresses the difficulty in

obtaining local power supply. In addition, the hybrid cable offers ultra-high

bandwidth and allows for one-off cabling to support network evolution for the

next 15 years.

-Green, low-carbon, energy-efficient outcomes: In the simplified architecture,

RUs require no planning, configuration, or management, reducing the number of

managed nodes by more than 80%. Furthermore, RUs adopt energy-efficiency and

fan-free design to achieve super quietness and energy saving, with the typical

power consumption less than 7 W for an RU and less than 1 W per port on average.

With unmatched technical expertise and experience in digital transformation,

Huawei will continue to dive deep into more urban rail use cases and work

closely with more customers and partners to jointly explore innovative

solutions. In this way, Huawei will help to accelerate digital transformation

in smart urban rail.
