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.
