Wi-Fi is one of the most popular Internet access methods. Monitoring Wi-Fi networks to ensure their normal operation is essential. WiFiMon ([1], [2]) is a GÉANT service offering open-source tools for efficient Wi-Fi network performance monitoring. The purpose of WiFiMon is to assist administrators in identifying underperforming segments within their networks and optionally enhance performance, for example, by installing more Access Points (APs).

WiFiMon combines various data sources, including WiFiMon Software Probes (WSPs) and WiFiMon Hardware Probes (WHPs). WSPs deliver crowdsourced measurements by reporting performance as experienced by end users roaming the Wi-Fi network, whereas WHPs trigger equivalent measurements from fixed network positions. WHPs complement WSPs by facilitating baseline performance comparisons, hence WHPs are integral to WiFiMon’s operation. WHP measurements mainly rely on Raspberry Pi devices, although any Unix-based device may be used. Optionally, in IEEE 802.1X networks WiFiMon may leverage on RADIUS and DHCP logs to enrich monitoring options, e.g. by reporting throughput per network Access Point.

In this presentation (attached), we provide an overview of WiFiMon and its architectural components, outline its fully automated installation procedure and report recent efforts on facilitating the distributed configuration and control of our WHPs.
