The guard interval of IEEE 802.11a /b/g is 800 ns. IEEE 802.11n can use the reduced guard
interval of 400 ns. You specify the guard interval on the WBM page "AP 802.11n
(Page 285)".
Modulation and coding schemes
The IEEE 802.11n standard supports different data rates. The data rates are based on the
number of spatial streams, the modulation method and the channel coding. The various
combinations are described in modulation and coding schemes.
