Optimizing the WLAN: University of Münster raises network quality to a new level!
The University of Münster is optimizing Wi-Fi networks during semester breaks and planning field operations on communications infrastructure and network security.
Optimizing the WLAN: University of Münster raises network quality to a new level!
On August 4, 2025, the University of Münster will use its semester break to carry out external missions in the area of communication and public relations. In this context, editors accompany university employees in their work, especially in the “Center for Information Technology” (CIT). The system electronics engineers Kai Lindemann and Jan Bleileven are part of this team. Your department is responsible for the development, planning and operation of communications networks.
A central project of these field missions is the optimization of the WiFi network in the university's combined heat and power plant (HKW). The plan is to install an additional LAN distributor and nine access points. These access points convert Internet signals into WiFi networks and are particularly important to meet the specific needs of HKW, which has large spaces and many metal and concrete structures. The university operates its own fiber optic network, which supplies 240 buildings and grew by 35 kilometers in 2023.
WiFi optimization and challenges
The university has around 57,000 LAN connections and almost 9,600 telephones. In total, around 300,000 devices, including sockets, telephones, computers and network components, are connected to each other. To ensure clarity, each cable and module is given a number. An employee continuously documents all plans and data in this regard.
What is particularly noteworthy is that the CIT receives an alarm about a defective access point in the Vom-Stein-Haus during its operations. Jan Bleileven is dispatched to check and repair the problem. He appreciates the flexibility and mobility of his job, while noting that his training ends in January 2026.
Technical tips for a stable WLAN
The factors that contribute to a stable WLAN are diverse. Too many WiFi networks on the same frequency can cause both stability and speed problems. This problem often occurs in densely populated areas. A common solution is to switch to a different frequency band with less radio operation. Apps such as FRITZ!WLAN, Wifi Analyzer or SSIDer, which display occupied frequencies and channels, offer assistance in checking radio operation.
Additionally, it is recommended to use reception channels 1, 6 or 11 as these provide the best results in a typical WiFi setup. For more comprehensive analysis, there are various Wi-Fi optimization software tools. These include, among others:
- Homedale: Zeigt umliegende WLAN-Netzwerke mit Details wie SSID und Signalstärke an.
- Wi-Fi Scanner: Analysiert WLAN-Netzwerke mit umfangreichen Filtermöglichkeiten.
- Netgear Genie: Überwacht WLAN-Verbindungen und bietet zusätzliche Funktionen.
These tools are helpful for visualizing signal strength and identifying connection problems.
In conclusion, the university Wi-Fi optimization initiative represents an important step in maintaining modern communication standards. The challenges associated with building structures and radio overload must continue to be addressed with innovative solutions. The university's staff demonstrate commitment and expertise to provide a secure and reliable network.
