WiCy: Monitoring 802.11AC Networks At Scale
summary
Describes why USB Wi‑Fi adapters fail to capture high-speed 802.11ac traffic (due to MU‑MIMO, beamforming, up to 8 spatial streams and 80–160 MHz channels) and presents an approach that repurposes access point hardware to build scalable 802.11ac monitoring systems. Covers the challenges of monitoring modern AC networks and provides the code and scripts needed to create a custom AP‑based monitoring platform.
