This an IEEE 802.11 a/g/p transceiver for GNU Radio that is fitted for operation with Ettus N210s and B210s. Interoperability was tested with many off-the-shelf WiFi cards and IEEE 802.11p prototypes. The code can also be used in simulations. Example gnuradio-companion flowgraphs are installed with the package and can be found in: - (Linux/macOS) $CONDA_PREFIX/share/gnuradio/examples/ieee802_11 - (Windows) %CONDA_PREFIX%\share\gnuradio\examples\ieee802_11
