Cisco ACU - surveying at different rates

[hrios]

When I perform site surveys, I notice that no matter what data rate I select (1,2,5.5,11), there doesn't seem to be any difference in the signal to noise ratio.

I'm asking this question because sometimes I want to create 2Mbps cells only, or 11Mbps only, etc.

Am I not interpreting the information correctly or am I doing something wrong on the ACU.

thanks
