Re: mcs index and data rate

As you can see from the table keya_n linked, the mcs index on it's own doesn't say a lot.

Where do you see this msc value? What are you trying to figure out? Are you using controller or IAP?

Re: mcs index and data rate

The mcs rate changes all of the time, sometimes even packet to packet, and that is to be expected.  That would happen because of a whole range of reasons.  It is not looked at often because it is not the biggest determining factor of performance.  A device can have a high mcs rate, but still perform horribly.
