At Wi-Fi Design Day 2019 in Birmingham, UK, I gave a talk on the uses for Wi-Fi sensors and performance monitoring software during WLAN design. These tools are often considered for day 2 operations, yet they offer real benefits throughout the full WLAN lifecycle. This is an extended version of the brief talk I gaveContinue reading “Wi-Fi Design Day 2019: Wi-Fi Performance Monitoring as a Design Tool”

It would be nice to be able to secure these networks the same way we do with internal SSID’s–mutual authentication of the client and network, and strong layer 2Continue reading “The State of Guest Wi-Fi Security”

Perhaps the gold standard is to follow the client with a laptop running Omnipeek and several Wi-Fi adapters all capturing frames on different channels. I’m also impressed with 7signal’s recent update to Mobile Eye which now logs roaming data as well. ButContinue reading “Roaming Analysis using only a Mac and Wireshark”
