[ath9k-devel] Fixing the rate and rate relationship to OFDM

[shinnazar <seytnazarovsho@ynu.ac.kr>]

You should look at minstrel_ht code. there you can set specific rate at all
retry stages. But I think you should care about the error level, because
high error rates decreases Aggregate frame length consequently shows very
little throughput that may be not tolerable for your application.

Subject: [ath9k-devel] Fixing the rate and rate relationship to OFDM

Many people seem to desire the bit rate to be the 'highest possible', and
have that automagically set.

For some applications, I like to be able to set a specific bit rate, and
have that bit rate used no matter the resulting errors.

I have looked a the code briefly, and it seems that there is the possibility
for setting up several retries, with changes in bit rate.

So, the questions are:

1) how to 'fix' a rate, disable adjustments on retries, etc?
2) What is the relationship between the bit rate selected at this OS level,
and the subcarrier modulation of the RF signal?

Thanks,
John Clark.
