1、 Project name

Successful case of wireless coverage scheme of fengrunda Zhengzhou locomotive depot office building

2、 Project background

Zhengzhou locomotive depot is an important driving department in Henan railway transportation system, which is mainly responsible for the operation, comprehensive servicing, overall maintenance, etc. of railway locomotives in Zhengzhou section, and is responsible for the power traction task of passenger trains, freight trains, luggage trains or special transportation tasks.

Zhengzhou locomotive depot office building is located near Zhengzhou railway station, with a total of 9 floors. In order to better carry out work and serve the masses, fengrunda is required to build a stable wireless network for the whole building.

3、 Customer needs

1. The wireless network signal needs to cover the office area of the whole office building, and the layout is beautiful;

2. The wireless signal shall be strong, stable and reliable, try to avoid interference and be able to roam seamlessly;

3. The wireless network must have strong anti-interference ability and try to be green and healthy;

4. The wireless network must have compatibility and scalability;

5. All APS are uniformly managed by AC to achieve real-time monitoring and management of APS;

6. An intelligent router with strong data forwarding and behavior management capabilities and firewall functions is required as the exit route;

7. The core switch needs to support the management of web interface, telnet and cli interface, and has a stable and powerful data forwarding capability;

4、 Solutions

According to the environmental analysis of Zhengzhou locomotive depot office building and customer needs, we use high-power ceiling mounted wireless AP rd-w68ap as wireless equipment; Ns2024g with powerful management function is adopted as the core; Poe switches ps3016 and ps3024 are used to power the wireless AP and transmit data; Use the wireless AC controller to uniformly manage all wireless APS.

6、 Solve customer problems

1. The original network has not changed, and the access of wireless coverage related equipment has been smoothly expanded;

2. There is no need for cumbersome strong current wiring, and Poe switches are used for power supply;

3. The wireless device supports IEEE 802.11 n, and the theoretical throughput can reach 300 Mbps;

4. The entire wireless network has sufficient security capabilities, has a perfect authentication system, supports a variety of encryption methods, and analyzes the security status of the wireless network in real time;

5. The whole set of wireless network equipment provides management functions, and realizes dual AC management in combination with fengrunda AC platform, which can carry out real-time monitoring and analysis, and can carry out real-time early warning for equipment and network failures; The fault point and cause can be found in time after the fault occurs.

6. The wireless system should be able to display the status of the wireless AP, the access of wireless users, and the unified management and configuration of the wireless network.

7、 Program value

1. Network management: use fengrunda AC controller or cloud AC platform to manage ap uniformly;

2. Security: wireless AP supports multiple encryption methods, which can effectively control and detect illegal access;

3. Network upgrading and expansion capacity: the entire wireless system needs to have flexible upgrading and expansion capacity to ensure the expansion of the entire office environment;

4. System compatibility: certain equipment compatibility issues shall be considered in the planning of the whole wireless network to ensure that the new equipment can operate normally in the wireless network.

5. Network load balancing: each AP in the wireless network has a load balancing function, which can balance the load on each AP according to the number of users or traffic of the system, so as to avoid the excessive load on an AP, which will degrade the performance of the wireless network in a region and cause link instability. The wireless network adjusted by load balancing has better network performance and can provide good wireless performance for more wireless terminals, Ensure the performance of wireless network.
