Open Wifi Part 1: Understanding OpenWrt, OpenWiFi, and Wireless Stack
A practical mental model of how an open Wi-Fi system is built, from the operating system and networking software to the Wi-Fi hardware and radio layer.
N3IWF- Seamless handover between 5G and Wifi
In this post, I’ll share some insights on some basic considerations in order to be able to utilize N3IWF for seamless handover between 5G networks and Wifi.
N3IWF- A brief introduction
3GPP is a global collaboration of telecommunications standards organizations that develops the technical specifications for mobile networks, including:
3G (UMTS)
4G (LTE)
5G (5G NR, 5G Core)
Now working on 6G concepts (as of 2025)
3GPP has defined many functions and standard for 5G communications. One of them is N3IWF.
