15. Define both minimum Basic and optimal Supported rates as required for the 802.11b rates, 802.11g rates and 802.11n rates
supported by the 2.4 GHz band and 802.11a and 802.11n rates supported by the 5.0 GHz radio band. These are the rates
wireless client traffic is supported within this mesh point.
If supporting 802.11n, select a Supported MCS index. Set a MCS (modulation and coding scheme) in respect to the radio's
channel width and guard interval. A MCS defines (based on RF channel conditions) an optimal combination of 8 data rates,
bonded channels, multiple spatial streams, different guard intervals and modulation types. Clients can associate as long as
they support basic MCS (as well as non-11n basic rates).
