Hi,
When I use Mango 802.11 Ref1.4 version , I tried to modify data rate from 20MHz to 10MHz, and I reffered the website:
http://warpproject.org/forums/viewtopic.php?id=2754
I did success changing bandwidth to 10M.(When I use Spectrum analysis instrument, the bandwidth shows 10M.)
But when I tried to communicate AP and STA using throughput_two_nodes.py, the Two-way communication cannot be established.
(The throughput shows 0 no matter in AP->STA or STA->AP)
I really don't know whether system.bit or C code causes this problem. (They are both modified by me)
I am confused the reason why the problem occurs ?
Can you help me or give me some suggestions ?
Thanks a lot !

It's hard to say what exactly failed after your modifications. Does your receiver successfully decode 10MHz waveforms?
We will soon be releasing version v1.5 of the Reference Design (hopefully by the end of the week, though possibly sometime next week depending on how development proceeds). This design natively supports 10MHz, 20MHz, and 40MHz of bandwidth at runtime through wlan_exp control. The full changelog for the design is already posted.

Hi, thanks anyway.
I've found the reason. I forgot changing upsample module to 16 in AGC.mdl
So now AP and STA can communicate with each other!
