Description P 2016-01-15 23:37:19 UTC

I found txVector.GetChannelWidth() has return value in MHz units. but yans-wifi-helper.cc use in Hz units.

for example.

if (txVector.GetChannelWidth () == 40000000)
    {
                mcsFlags |= RadiotapHeader::MCS_FLAGS_BANDWIDTH_40;
    }

It looks indeed not correct.

When implementing 802.11ac, I had originally chosen for getting the bandwidth in Hz, but then I went back to Mhz units. Apparently that part of the code was forgotten to be adapted. I will test and prepare a fix today.

I added a fix for this bug.
Since it is an obvious one, I will deliver it in ns-3-dev immediately.
Thanks for reporting!
