Ruijie's "Pioneer Wireless Office" settled in the Fortune 500 Kangmei Pharmaceutical and solved Wi-Fi problems in depth

Today, deploying Wi-Fi has become an important part of the business environment of enterprises. However, the comfortable office environment that enterprises have worked hard to create is often the focus of employee complaints because of poor Wi-Fi. In order to allow all employees to use "truly easy-to-use" Wi-Fi, Kangmei Pharmaceutical Co., Ltd. (hereinafter referred to as "Kangmei Pharmaceutical") adopted Ruijie Network's "Pioneer Wireless Office Solution" to completely solve the three major problems of "remote association, frequent roaming, and air interface occupation" in office Wi-Fi applications, and achieved a significant improvement in office efficiency.

As one of China's top 500 companies, Kangmei Pharmaceutical has made frequent informatization construction, from "smart pharmacy" and "network hospital" to "Kangmei e-Pharmacy Valley" and "Health Think Tank", and informatization has achieved full coverage in e-commerce, marketing, management, services, etc. At the same time, Kangmei Pharmaceutical is carrying out wireless office network construction work at its headquarters, more than 70 branches and multiple production bases, and the headquarters wireless office network is the benchmark.

Prescribe the right medicine for the right situation and go deep into the scene to "find the fault"

Zhang Chun, CIO of Kangmei Pharmaceutical Headquarters, said: "Thanks to the development of Internet services and WLAN technology, our traditional office environment has gotten rid of the intrusion of network cables. Real-time communication, BYOD, wireless printing, and wireless projection all rely on Wi-Fi networks. Therefore, to maintain the continuity of work and the smooth progress of various business processes of the enterprise, a wireless network with a strong and stable signal is obviously indispensable. However, the wireless network application built by Kangmei Pharmaceutical Headquarters in the early days was not "satisfactory."

Before recommending solutions to users, Ruijie Networks conducted in-depth research on application scenarios to find faults. This pragmatic approach quickly won the recognition of Kangmei Pharmaceutical.

On-site survey found "three major root causes"

Based on the feedback from company leaders and employees, Ruijie engineers conducted on-site research in Kangmei Pharmaceutical's office scenarios and worked with Kangmei's IT department to conduct a large-scale survey on the issues of "slow network, frequent disconnections, and inability to connect to the Internet." They ultimately identified the three main causes of poor Wi-Fi experience.

Remote association diagram

First, there are a lot of "remote associations" in wireless office networks. In layman's terms, it means that user devices choose APs that are far away rather than near. There are many scenarios that cause this problem, such as: unequal AP power, obstacles blocking signals, and interference affecting signal quality. This will cause large delays and high packet loss, and will also reduce the overall performance of the AP, which is a major cause of "slow network".

Secondly, the original network has the problem of "frequent roaming" caused by interference between wireless APs and random deployment locations. The reason is that wireless APs support active roaming. When a user walks to an area with a stronger AP signal, the remote AP will actively disconnect the user and the nearby AP will actively connect the user to the Internet. However, if the original AP signal jitters violently, the user terminal will look for a better AP. This situation happens repeatedly, resulting in frequent roaming, and users will naturally feel "frequent disconnection" or repeated verification problems.

Finally, in the high-density office environment of Kangmei Pharmaceutical, when there are too many users accessing the wireless network, the terminals will randomly occupy the AP air interface resources, causing a significant drop in performance. At this time, it is difficult for new users to access, or the network performance will drop to the point where it is almost unusable after access, which is why employees often complain about "not being able to access the Internet."

When AP air interface resources are occupied out of order, the channel is almost unavailable.

Pioneer Office helps "big health"

After repeated consideration of the products, technologies and networking solutions in the original wireless solution, Kangmei Pharmaceutical finally gave up the "patching up" method, completely upgraded the wireless office network, and decided to adopt the Pioneer Wireless Network Office Solution provided by Ruijie Networks. This solution includes unique wireless radio frequency technologies such as Pre-ax and Clink, which can effectively solve the self-interference problem of densely deployed APs, guide terminals to intelligently associate, and reasonably allocate wireless air interface resources. It is particularly suitable for high-density and high-concurrency large-open-plan wireless office scenarios.

Pioneer office solutions enhance the connected experience

During deployment, Ruijie selected AP models in a targeted manner based on office scenarios, and redesigned AP access locations in combination with obstacles, walls, and workstation layouts. At the same time, the direction calculation unit of the AP's built-in antenna was used to dynamically adjust the directional beam direction or gain according to the terminal's location and signal quality; in response to the disorderly occupation of air interface resources, Ruijie Networks used X-speed's patented wireless network acceleration technology to achieve fair occupation of wireless air interface resources through traffic shaping.

Finally, the problems of remote association, roaming stickiness, and low-speed terminals in Kangmei Pharmaceutical's wireless network were completely solved, and the association stability was improved to 100%. At the same time, the WLAN of Kangmei Pharmaceutical's headquarters also adopted 802.11ac technology, and by guiding the 5G channel, the 460 terminals in the headquarters office building received the ultimate Wi-Fi experience.

Pioneer Office Solution reduces channel utilization and improves online experience

Zhang Chun, CIO of Kangmei Pharmaceutical Headquarters, is very satisfied with the implementation effect of Ruijie Pioneer Office Solution. He said: "The establishment of the wireless office network has promoted Kangmei's pursuit of the corporate goal of 'Internet + Big Health'. The overall solution is almost tailor-made, which comes from the repeated field surveys and the innovative technologies involved in the solution. At the same time, Ruijie's RG-WIS wireless intelligent service system deploys intelligent network optimization tools, problem identification and other modules, and realizes the dataization and visualization of wireless network operation and maintenance management, which greatly saves manpower and really improves efficiency.
