## What it is
Open-source full-stack IEEE 802.11/Wi-Fi design based on Software Defined Radio, including a Linux mac80211-compatible driver and software, with the FPGA baseband design in a companion repository. It runs on Xilinx Zynq with Analog Devices AD9361 hardware and supports 802.11a/g/n with research-oriented features like packet injection, CSI extraction, and joint radar-communication.

## Use cases
- build a software-defined WiFi transceiver on FPGA
- inject and fuzz 802.11 packets for security research
- extract WiFi channel state information for sensing
- implement WiFi-based radar and motion detection
- run a custom open-source WiFi AP or station on Linux
- experiment with low-latency CSMA/CA MAC in FPGA

## When to choose
- you need a fully open-source 802.11 baseband and driver stack for research
- you want low-level control over WiFi MAC parameters, packet injection, or CSI
- you work with Zynq/AD9361 SDR hardware and Linux mac80211

## When to avoid
- you just need a normal WiFi card or consumer router
- you lack SDR/FPGA hardware like Zynq with AD9361
- you need commercial support or advanced features without a subscription
- you must strictly avoid spectrum-regulation compliance responsibilities
