Re: [Discuss-gnuradio] updated BBN 80211 code for current release (3.1.3)?

Hi Doug,

 

Thank you for the information provided. Definately I will go to check your codes. However, I do not think I can contribute now because I am still quite new to these stuff. I do hope I can put some contributions someday. :)

 

I am still have some questions/comments as below:

 

1) From your experience, what are the major challenges to port the BBN 802.11 codes to the newer gnu radio release?

 

2) Why doesn't gnu radio team include BBN 802.11 code in their office release, just same as what they have done to the m-block codes? Then these codes would be better maintained and utilized.

 

3) BBN 802.11 codes are only compatitable with some older version of gnu radio (v3.1.1). If I have to use the lower version gnu radio in order to utilize the bbn 802.11 codes, what power and functionality I will lose from not using the new current ralease. Is this an acceptable alternative? Maybe I can not use the new USRP2 boards since they are just newly released and probably not supported by the older version gnu radio. what else?

 

4) Most people who need BBN 802.11 PHY codes also need to work on MAC layer, mostly working on Click modular router. As I saw in some papers, BBN also implmented two APIs (an MAC-Subnet API for Click to use to talk to the MAC layer, and aonther Radio API for MAC layer to talk to the GNU Radio) and a model MAC in Click. They are supposed to be open-sourced. Have you used them or know where to find them?

 

Thanks.

I've been on and off working on this, and expect to be spending more
time on it now. However, I don't currently have anything that works with
the latest stable release.  I have a branch in the bbn_80211 project
(https://www.cgran.org/cgran/projects/bbn_80211/branches/douggeiger) if
you want to see what I'm working on at the moment - but again, it is not
currently functional. If you want to take a look and help (send
patches/suggestions, etc.) that would be welcome.
