Who is behind this project
A Wi-Fi sensing reference built from our own lab and three decades of networking.
Wardner Maia has worked in internet and telecommunications since 1995. He was a founding board member of ABRINT, Brazil's largest association of regional ISPs, and is a director of LACNIC, the regional internet address registry for Latin America and the Caribbean.
This project grew out of a simple observation: Wi-Fi sensing is moving from the lab to the product, and Brazil has thousands of ISPs that will own the equipment this technology runs on. They need independent technical information, in their own language, to make decisions.
The lab
The lab is based at Estância Terracota, an event venue in Bebedouro, São Paulo, that doubles as a real-world sensing environment: people arrive, move around, gather and leave, just as in any space an ISP serves.
The infrastructure is being set up and combines OpenWrt routers, ESP32-S3 (2.4 GHz) and ESP32-C5 (5 GHz) nodes dedicated to CSI capture, and a passive monitor-mode capture pipeline. Device identifiers are pseudonymized at capture time. Results will appear under Updates as they are validated.
Editorial principles
Separate product from promise
Every application is shown at its real stage: in production, pilot or research.
Show the source
Data, standards and news are cited with their origin so readers can check.
Publish what did not work
Negative lab results are information too.
Privacy as a technical requirement
Handled in the system design, not as a footnote.
