Learn about GÉANT's WiFiMon service for monitoring Wi-Fi network performance in this 20-minute conference talk from NANOG. Discover how the open-source monitoring tools combine Software Probes (WSPs) for crowdsourced measurements from end users and Hardware Probes (WHPs) using Raspberry Pi devices for baseline performance comparisons. Explore the architectural components, automated installation process, and recent developments in distributed configuration and control of Hardware Probes. Gain insights into leveraging RADIUS and DHCP logs for enhanced monitoring capabilities in IEEE 802.1X networks, helping administrators identify and improve underperforming network segments. Presented by Nikos Kostopoulos, a Ph.D. Candidate at National Technical University of Athens and software developer for GÉANT WiFiMon.
