To reduce the size of the power table, multiple wireless data rates are grouped into a single rate group
as shown in
Table 29 :
Rate group Mode Description
0 11b 20 MHz CCK (1,2,5.5,11 Mbit/s)
1 11g 20 MHz OFDM (6,9,12,18 Mbit/s)
2 11g 20 MHz OFDM (24,36 Mbit/s)
3 11g 20 MHz OFDM (48,54 Mbit/s)
4 11n/ac 20 MHz MCS 0,1,2 HT20/VHT20
5 11n/ac 20 MHz MCS 3,4 HT20/VHT20
6 11n/ac 20 MHz MCS 5,6,7 HT20/VHT20
7 11n/ac 40 MHz MCS 0,1,2 HT40/VHT40
8 11n/ac 40 MHz MCS 3,4 HT40/VHT40
9 11n/ac 40 MHz MCS 5,6,7 HT40/VHT40
10 11ac 20 MHz MCS 8 VHT20
11 11ac 40 MHz MCS 8,9 VHT40
12 11ac 80 MHz MCS 0, 1, 2 VHT80
13 11ac 80 MHz MCS 3, 4 VHT80
14 11ac 80 MHz MCS 5,6,7 VHT80
15 11ac 80 MHz MCS 8,9 VHT80
Table 29: Rate group information for one spatial stream
The configuration file example above sets the following transmit power limits for channel 1 and 2 in
the 2.4 GHz band:
• 12 dBm for 802.11b rates (BPSK, QPSK, CCK)
•
11 dBm for 802.11g OFDM (6, 9, 12, 18 Mbps; 24, 36 and 48, 54 Mbps),
• 11 dBm for 802.11n HT20 (MCS 0 to MCS 7)
☞
For HT40 operation in the 2.4 GHz band (HT40 MCS0-7), the transmit power limits are selected
from the channel of the center frequency. For example, the first 40 MHz channel at the center
frequency 2422 MHz (20 MHz channels 1+5) uses the transmit power limits from HT40 values
in the entry with
TLVChanNum=3
