Wi-Fi 7 router streams raw radio samples as a software-defined receiver

github.com 5 min read Editor score 7/10

The project repurposes a router’s MediaTek radio to capture 14-bit IQ samples at up to 320 Msps and stream them over 10 GbE, using custom firmware. Its radio and streaming pipeline make for a substantial performance-engineering project.

What: W1700K SDR turns a Wi-Fi 7 router into a software-defined receiver that streams raw radio samples to a Linux host.
How: The MT7996 captures IQ samples, the Airoha AN7581 SoC sends them over 10 GbE, and host software provides a shared stream and spectrum display.
Why it matters: The design shows how radio capture, high-throughput transport, and shared host-side consumers fit into a live data pipeline.

Radio samples move from the router across 10 GbE to host streaming and spectrum software. Sketched from the article's own text.
