Seamless roaming plus wired office access: When office staff move across different floors and areas with mobile phones and tablets, Wi-Fi must support imperceptible roaming switching among wireless access points without signal disconnection or reconnection, ensuring stable network speed for daily office work.

Cut internal communication costs: Frequent daily communication is required among dormitories, monitoring rooms and offices. Traditional external dial-up calls bring continuous communication expenses. A free internal extension call system is in demand to realize direct dial connection and improve team collaboration efficiency.

Powerful emergency broadcasting function: In case of emergencies, severe weather and lane faults, the monitoring center needs to release emergency alerts and official notifications to the whole station or designated areas with one click, and issue evacuation instructions timely especially during peak passenger flow in service areas.

Integrated study and entertainment services in dormitories: Frequent staff movement inside dormitory buildings requires full Wi-Fi coverage with seamless roaming across rooms and floors. In addition to live TV and on-demand video entertainment after work, terminal devices also need to support political learning, professional training and safety education content playback, satisfying both recreational and educational needs.

Stable long-distance data transmission: Restricted by the 100-meter transmission limit of traditional network cables, it is hard to meet the transmission demand between remotely separated office areas and service areas. Public Wi-Fi needs to cover indoor service buildings and outdoor zones, supporting high-concurrency access during peak hours and standardized Portal-based user authentication.
