Wi-Fi engineering, down to the frame.
Co-hosts Roel Dionisio and Francois Verges talk about Wi-Fi the way engineers practise it: Wireshark filters, spectrum waterfall views, dorm validation surveys and dashboards built from APIs. The tone is friendly and practical, and some episodes are built around shared screens, so the video version carries the visuals.

Clear To Send: Wireless Network Engineering is a Wi-Fi engineering show that rarely strays far from the tools. Co-hosts Roel Dionisio and Francois Verges keep things relaxed and practical. Roel opens one episode still sick, a cough drop in his mouth, hoping not to cough through the recording. Then they get to work. In 'CTS 383: Deep Dive – Wi-Fi Troubleshooting at the Frame Level', the pair open packet captures in Wireshark. They use a simple capture to show how an exchange looks when everything is working, and show how filtering on one MAC address cuts through a channel full of traffic from many devices. They also note that the same habits apply above layer two, at layer three. 'CTS 381: Deep Dive: Using Spectrum Analysis Tools' does the same for RF. The density view and the waterfall view are explained in plain terms, and the case for learning signal shapes is simple: see Wi-Fi often enough and you start to recognize it, though lookalike signals can still mislead. Because so much of this is visual, the hosts suggest audio listeners catch the spectrum material on YouTube. Monitoring comes up more than once. 'CTS 385: Building Your Own Wi-Fi Dashboard Using APIs and Grafana' follows Roel's Grafana learning experience, down to the functions that query an API for connected access points, count the ones online and timestamp the result for InfluxDB. Links to a Postman collection and API documentation are promised in the description. The live events episode takes the same idea into the field. Francois does a lot of event support, and the talk turns to clients per AP, channel utilization, saturated channels and why vendor dashboards do not always show those numbers. That gap is where custom scripts and Grafana dashboards come in. Roel's solo episode, 'CTS 386: A Day in the Life of a WLAN Engineer', swaps tools for routine. He describes on-site WLAN work at Stanford University from both a higher education angle and a consulting one. Part of the job is reviewing validation surveys from a trained team: checking that surveyors walked the path as they tapped the screen, and did not walk through walls. Dorms are a problem of their own, since nobody wants to walk into an occupied or chaotic room. Not every episode is technical. 'CTS 382: Our Resolutions for the New Year' covers goals for business, health and relationships, and one host describes asking customers a simple feedback question: did you have fun working with us? Questions go to the comments and a Slack community, and the hosts also mention LinkedIn and X as places people get in touch.
Made for: Suits a wireless engineer or Wi-Fi enthusiast who wants packet captures, spectrum views and API-driven dashboards worked through step by step. Also a fit for someone curious about the everyday work behind campus and event networks.
What sets it apart: The hosts put the tools on screen, from Wireshark filters to spectrum waterfall views to the code behind a Grafana dashboard, so episodes work as demonstrations as much as conversations. Field detail, such as dorm validation surveys and channel monitoring at events, keeps the talk tied to real networks.
