Re: [Discuss-gnuradio] Scanning/Detecting Wifi

G'day Greg,

I've updated pkgsrc/ham/gnuradio-core to 3.0.2nb1. It fixes a bug that I 
encountered in gr.firdes.band_reject() function.

At least it returns the expected result :-)

cheerio Berndt

Thank you so much for the info.  
could you please tell me what makes us to believe that USRP board is able to 
detect wifi(802.11b ) .
one more question is what kind of signals the siggen.py is generating?

thank you in advance
Ravi

This code is a bit rough and not yet integrated, but you should be
able to get it to run:

cvs -d [EMAIL PROTECTED]:/cvs/adroitgrdevel co adroitgrdevel

look in gr-bbn/src/bbn, which is quite misnamed but has 802.11 demod
for the 1 Mb/s rate.

I found that I can see a lot of structured noise on, e.g., the frequency
2.467G (802.11b channel 6) using my RFX2400 and the usrp_oscope script
in the gnuradio-examples/python/usrp directory. That gives me good
indication that the board works.

Also, if you have two boards, run usrp_siggen on one and usrp_oscope on
the other. You get nice sine waves.
