Re: Link adaptation in source code

Hi Alex.

Its called "Dynamic rate scaling" I have seen the (broadcom) bcm
drivers and in general the rates are dropped, if the RSSI / signal
strength goes down or if there are missed beacons and lot of frames
with bad CRC, Overall when the rates drop, it means there are physical
obstacles (OR) signal strength drop between station to AP. I am sure
you can figure it out in the code. If you need help, let me know.

Thanks
Ramesh

(e.g. when the distance between the station and access point increases the date rate may automatically change from 54Mbps to 36Mbps). So, would it be possible to see in the driver when such a decision was made and know in advance that the next frame will be transmitted with a new date rate?
