Hi Adrian,
We observed that this can happen for any rate for some SNR values.
If the SNR is strong enough for the given MCS this won't happen.
But when the SNR approaches the transition region when
error rate starts to increase, this problem will be observed.
So this can happen even for

The paper mentioned that this happens when the client is mobile.
But I confirm Adrian's observation . This problem happens even
in stationary environments with dynamic channels (e.g., people moving in
the vicinity
of the AP/Client).
Best,

Just finally -
MCS20 - MCS23 are very sensitive to changing channel anything. See if
you can find or make some required SNR curves for each MCS rate.
So although it doesn't surprise me to find this is happening, it's
very cute that someone's gone and done the work of figuring out how to
improve
Hi Seongho,
that paper looks quite interesting.
Are you planning to publish code/patches for your implementation as well?
It would be nice to have dynamic A-MPDU limiting integrated in minstrel_ht.
Thanks,

Hi Adrian,
We have a high end spectrum analyzer. So we are sure there is no
background interference
We run our experiments in the 5 GHZ spectrum. The channel conditions can
still vary due to
