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.
