About · Wi-PHY

I'm a Software Engineer working in the Wi‑Fi domain.

I enjoy learning how wireless technologies work, from 802.11 protocols to the Linux Wi‑Fi stack and embedded networking. Over the years, I've spent much of my time testing, debugging, and exploring different aspects of Wi‑Fi, and built Wi‑PHY as a place to organize and share what I learn.

The articles on this site are based on my learning, practical experience, experiments, and research. My aim is to explain Wi‑Fi concepts in a clear and practical way, with a focus on understanding how things work rather than just describing features.

Wi‑PHY covers topics such as wireless protocols, Linux networking, OpenWrt, hostapd, Wi‑Fi security, packet analysis, troubleshooting, and other areas that I find interesting as I continue learning. If you find something useful here, or have suggestions or corrections, I'd be happy to hear from you.

Thanks for visiting.
