I've had a closer look at this.
The sensitivity basically controls the roaming threshold when handled by
firmware. It is a firmware setting, though the Agere driver also
validates the multicast rates based on it. The drivers/firmware use
terms like system scale, AP density, distance between APs.
There are 3 valid values:
3 - high density of APs. Maintain 11Mbps by roaming.
2 - medium density of APs. Maintain 2Mbps.
1 - low density. Maintain 1Mbps.
Although the values are defined in terms of the usable bitrate, the
(Intersil) documentation states that the implementation is based on SNR.
Dave.
