4. Configure rates for 802.11g.
dot11g { disabled-rate |

rate-value
Optional.
By default, mandatory rates are
1, 2, 5.5, and 11; supported
rates are 6, 9, 12, 18, 24, 36,
48, and 54; no rates are
disabled.
Configuring 802.11n rates
Configuration of mandatory and supported 802.11n rates is achieved by specifying the maximum MCS
index. The MCS data rate table shows relations between data rates, MCS indexes, and parameters that
affect data rates. A sample MCS data rate table (20 MHz) is shown in
Table 1 , and a sample MCS data rate
table (40 MHz) is shown in Table 2 . For the whole table, see IEEE P802.11n D2.00 .
As shown in the two tables, MCS 0 through MCS 7 use one spatial stream, and the data rate corresponding
to MCS 7 is the highest; MCS 8 through MCS 15 use two spatial streams, and the data rate corresponding
to MCS 15 is the highest.
