Quick Start Guide: Wi-Fi HaLow on Raspberry Pi 4

This is a digital field manual. No hardware included. 

This quick-start guide turns a Raspberry Pi 4 into a Wi‑Fi HaLow gateway, pairs it with a Xiao MCU client, and walks you through validating performance in real-world conditions: long-distance links, live video streaming, and through-wall/through-concrete testing.

By the end you’ll have:

• A working gateway + client link (sub‑GHz IP)
• Measured range and obstacle performance
• Reusable code/config you can modify and redeploy
• A repeatable workflow for remote deployments

Who it’s for:

• Makers and experimenters
• Off-grid/farm/cabin projects
• Prototyping and edge networking

What you’ll need:

• Raspberry Pi 4
• Xiao MCU
• Wi‑Fi HaLow radio hardware (see included parts list)
• Basic familiarity with the Linux command line

No cloud dependency. No subscription. Just your hardware, your network.
