Shenzhen Metro is deploying a Cisco (CSCO) Unified Wireless solution to build a comprehensive wireless network for its Passenger Information System on the city's high-speed Line One subway.
The network will enhance business operations for the metro operation and bring added value and convenience to passengers. Based on Wi-Fi technology, the Cisco solution supports high-density digital TV broadcasting and facilitates real-time monitoring of the metro's control center.
The PIS system can transmit a high-definition digitally encoded signal in real time from the central control room to moving trains. Passengers can watch high-quality digital TV programs on the LCDs in each carriage and receive news, weather reports or emergency evacuation alert messages. Through the video display, subway drivers can understand the situation of the station platforms as well as that inside the moving cabin, which helps ensure the safety of the metro operations.
The first phase of Shenzhen Metro's Line One subway runs 17.55 kilometers through the city from Luo Hu in the east to one of the Shenzhen's key attractions, "Window of the World", in the west. The company's upgraded Passenger Information System not only improves communication between moving metro trains and the control room, but also strengthens its leadership role by providing an innovative experience for its metro passengers.
Cisco has provided the latest Unified Wireless solution for Shenzhen Metro's PIS project. The core components include Cisco Aironet 1310 Access Point, an outdoor industrial product with outstanding stability and excellent control and security, and the enterprise-class Cisco Wireless Services Module. These will help Shenzhen Metro manage and expand its wireless PIS as conveniently as a traditional wired network.
