Configuration items
Item Description
802.11a
Configure rates (in Mbps) for 802.11a.
By default:
•
Mandatory rates are 6, 12, and 24.
•
Supported rates are 9, 18, 36, 48, and 54.
•
Multicast rate: Automatically selected from the mandatory rates. The
transmission rate of multicasts in a BSS is selected from the mandatory rates
supported by all the clients.
802.11b
Configure rates (in Mbps) for 802.11b.
By default:
•
Mandatory rates are 1 and 2.
•
Supported rates are 5.5 and 11.
•
Multicast rate: Automatically selected from the mandatory rates. The
transmission rate of multicasts in a BSS is selected from the mandatory rates
supported by all the clients.
802.11g
Configure rates (in Mbps) for 802.11g.
By default:
•
Mandatory rates are 1, 2, 5.5, and 11.
•
Supported rates are 6, 9, 12, 18, 24, 36, 48, and 54.
•
Multicast rate: Automatically selected from the mandatory rates. The
transmission rate of multicasts in a BSS is selected from the mandatory rates
supported by all the clients.
Configuring 802.11n MCS
Introduction to MCS
Configuration of mandatory and supported 802.11n rates is achieved by specifying the maximum
Modulation and Coding Scheme (MCS) index. The MCS data rate table shows relations between data
rates, MCS indexes, and parameters that affect data rates. Sample MCS data rate tables for 20 MHz
and 40 MHz are shown in
and
respectively. For the whole table, see
IEEE Std
802.11n™-2009
.
and
indicate that MCS 0 through 7 are for one single spatial stream, and when the
MCS is 7, the data rate is the highest; MCS 8 through 15 are for two spatial streams, and when the MCS
is 15, the data rate is the highest; MCS 16 through 23 are for three spatial streams, and when the MCS
is 23, the data rate is the highest.
