Hi,
I am using the command ./bbn_80211b_rx.py -d 8 -f 2.412G -b to catch 802.11
1 Mbps packets from access points. However, the result is always BAD CRC. I
know that some people on this list did it successfully.
I am using the bbn_8021/branches/usrp2_version and working with a USRP2.
Can anybody
Hi Rahman,
No, I have not been able to receive from USRP2 as a transmitter but I have
been able to successfully receive packets from a nearby access point.
Thanks,
Smith

Hi Smith,
Did you manage to receive with USRP2? I'm kinda stuck with the same problem
(Tx/Rx with 2 USRP2s). 'bbn_80211b_rx' does not receive what I'm
transmitting with 'bbn_80211b_tx'.
Thanks,
Rahman

George,
The latest versions of GNUradio no longer use omnithreads - I believe
everything the used them has switched over to using boost threads. I'm
not sure what portions of the BBN code use threads (I suspect there is a
watcher thread checking the message queue from the PLCP for received

Hi George,
I am using Ubuntu 8.04 and GNU Radio version is 3.3git-602-gfcf9efa7. I do
not know about Ubuntu but a lot of changes were made to git after I checked
out this version. If you have older versions of git then it may help you to
build usrp2 bbn code.

Hi George,
Were you able to test the usrp2_version code with two USRP2s?
Let me know if you were able to successfully transmit 80211b packets from
one USRP2 to another.
Thanks,

I do not remember specifically what I used at the command line to get the
two USRP2s to talk to each other. I know I had it working for 1 and 2 Mbps.
I think something must be messed up with the spreading sequence. George,
wasn't there a discussion on that sometime ago? I remember there were plots

Thanks George for your inputs.
I have closely been monitoring cgran website. However, every project seems
to be focusing on how well one can use USRP1 or USRP2 as 80211b receiver.
But my goal is to communicate between two USRPs (whether USRP1s or USRP2s)
using bbn 80211b code.

Hi Colby,
Were you able to communicate between two USRP2s using bbn 80211
usrp2_version code?
I am not able to receive packets using USRP2 receiver even when other USRP2
is transmitting. Can you please let me know if there are any changes
required to be made in the usrp2_version code or any spec
Cool to hear about the OFDM 802.11 project.
When I was working with the USRP2 version, I was only able to get two USRP2s
to talk to each other. I can't remember if I was able to get it to decode
packets from a chipset, that was a year ago.
I do remember that sometime ago, there was further di

Thanks for the help, Doug.
I do have two USRP2s and hence was also working on the usrp2_version code. I
have both the transmitter and receiver code individually working correctly
with USRP2. However, the receiver is not able to receive the packets
correctly from the transmitter (i.e in case of US
You probably want to take a look at the usrp2_version branch to see
how to get the transmit code working with the hier_block2 API, and
then modify it to work with the USRP1. Two things: you cannot transmit
the 802.11b waveform through the USRP1 (you don't have enough
bandwidth - in the original co
