About 80211_mac.tar.gz

GNU Radio
1

Hi,

I see from the mailing list in May 5th, 2009 that Ben Yahmed report
using
the 80211_mac.tar.gz and it works. Does anyone know what version of GNU
Radio can this script work? Does it only for USRP2?

I noticed that there are many version of simple_mac.py in this file?
Does
anyone know the differences between them?

Thanks

Chen

Here is his mail:

Hi, Thierry

I noticed that in this directory, simple_mac.py need the script of
bbn802_11b.py and bbn802_11b_pkt.py, but these two script are not in
this
directory. Are these two script from the USRP2 version of bbn code from
cgran?

Thanks,

Chen

Hi Thierry,

There are three version of bbn code: the original, the douglias version
and
usrp2 version. These three versions all have these two script. So which
version is right for the simple_mac.py

I have modified the simple_mac.py in the original bbn code and it works
for
the usrp. But it seems that the txpath and rxpath is from the class of
usrp_transmite_path and usrp_receive_path, not from the bbn 80211
module. It
is like the tunnel.py in the gnuradio directory.

I noticed that in 80211_mac.tar.gz, the simple_mac.py’s txpath and
rxpath
use the bbn transmitting and receiving module, which is different from
the
simple_mac.py in the original version. Do you know these differences?

Thanks

Chen
