Hello,
I have seen questions regarding the length of an AMPDU and how to change
the maximum AMPDU length.
However, I require to lock the AMPDU length at a specific value.
Changing the max length does not guarantee
that all AMPDUs have a fixed length, it can be anything between 1 to max
based on
As far as i know AMPDU length is determined by 3 constraints. Firs maximum
AMPDU length. second blockAck window (if there were losses then this will
play a role). Third is Max air time of the AMPDU which is 4ms for some
domain constraints. this comes into play MCS is low and packet duration
gets m
These mostly determine the MAX AMPDU length. I also want to determine
the minimum length, so
that I can set min=max and lock the AMPDU length.
Thank you,
Ali

do it at a fix rate (1st check if duration of packet is less tahn 4ms for
ur MCS) and with nearly zero noise losses.

Using a constant rate does not help (I am already doing this). When I
set the limit to 20 for example, I get any number between
1 to 20 for the number of aggregated frames. This is probably because
when we want to start the transmission
we don't always have 20 frames to aggregate so the card aggr
Hi Ali,If I were you, I would try to make the Software queue always full of frames and then specify ampdu lenfth in ath_tx_form_aggr().BR,Shinnazar

Yeah,
My initial premise was that u have saturated traffic from upper layers.
But now I think u have some application level requirements (data rate is
less than max PHY rate).
In this case I would advise you to add wait in mac80211. Because as far as
I know ath9k driven by its calls and calls by
