At the recent FOSDEM 2020 conference, introduced<\/a><\/noindex> project OpenWifi<\/a><\/noindex>, which is developing the first open implementation of the complete Wi-Fi 802.11a\/g\/n stack, with signal form and modulation defined programmatically (SDR, Software Defined Radio). OpenWifi allows the creation of a fully controlled implementation of all components of a wireless device, including low-level layers that in standard wireless adapters are realized at the level of chips that are inaccessible for auditing. The code of software components<\/a><\/noindex>, as well as schematics<\/a><\/noindex> (Verilog) of hardware blocks based on FPGA is distributed under the AGPLv3 license.<\/p>\n

The hardware component of the demonstrated working prototype is based on the Xilinx Zynq FPGA and the AD9361 universal transceiver (RF). OpenWifi uses the SoftMAC architecture, which implies the implementation of the core wireless 802.11 (high-MAC) stack on the driver side and the presence of a low-MAC layer on the FPGA side. The wireless stack uses the mac80211 subsystem provided by the Linux kernel. Interaction with SDR is done through a special driver.<\/p>\n
