This is what I found:

BBN has written 802.11 code under funding from DARPA.

To get the code: cvs -d address@hidden:/cvs/adroitgrdevel co
adroitgrdevel. After GNU Radio is installed, build it using
bootstrap/configure/make install to the same prefix.

This has been tested on NetBSD, and reported to work on Linux.

The following has been reported working

    * ? Mb/s transmit and receive without Barker code
    * 1 Mb/s receive with the Barker code 

Those experimenting with the code should be familiar with both GNU Radio and
802.11; this is not a good area for beginners.
