Hello Ben,
When I try to run the version of simple_mac that you posted, I get an error.
It seems like an infinite loop that prints to stdout:
2nstreams:
It happens at the call to fg.rxpath.start() .
Do you have the same problem?
Thanks,
Miklos Christine

Hi all,
I modified the gain in the bbn_80211_rx.py file from 46 to 27 and
the loss ratio has fallen down to 15-20%. Do you have any idea
about the best value to put?
this is the ping capture:

Hi all,
I succeeded to make the simple_mac.py working. now it's
pinging correctly but with a huge loss ratio. At first I
disabled the carrier sense functions but after I reactivated
them but I'm not sure these functions are working. I attached
the 80211_mac folder so any suggestion or amelioration is
welcome. I used this command line to run the python file:
./simple_mac.py -S 8 -v
I also hard_coded my mac adress so you need to change it
before use.
you can see here the results that I have obtained by ping:
