【Government】National-Grade Secure Smart Office for the Railway Bureau

High-Performance Wi-Fi 6 and Centralized Management Empower Digital Education

Building a National-Grade Security Wi-Fi 6 Smart Office Environment

To enhance administrative efficiency and strengthen information security, the Railway Bureau of the Ministry of Transportation and Communications (RBMOTC) has introduced a next-generation wireless network architecture for its offices in the Banqiao Station Building (9th–13th and 21st floors). This project deployed 30 high-performance Wi-Fi 6 Access Points (APs), utilizing a centralized management architecture and rigorous authentication mechanisms to create a modern government network environment that balances performance, security, and management efficiency.

Project Requirements & Challenges

-      Security Compliance & Authentication: 

Adhering to the national "Non-China Made" equipment policy and implementing 802.1x authentication and WPA3 encryption to ensure the security of sensitive data transmission within the building.

-      Seamless Full-Area Coverage: 

Providing comprehensive signal coverage for the 9th–13th and 21st floors, eliminating dead zones caused by partitions to ensure uninterrupted service during cross-floor movement.

-      High-Density Connection Capacity: 

Addressing high personnel density by requiring each AP to support 256+ concurrent connections, resolving bandwidth congestion and latency issues.

-       Centralized Visual Management: 

Replacing inefficient standalone management with a centralized platform that provides real-time network status and reduces IT maintenance workloads.
