Frequency band and operating
channels
channels
FCC: (-A)
●
2.412–-2.462 GHz; 11 channels
●
5.15–-5.25 GHz Unlicensed National Information Infrastructure (UNII-1), 5.25–-5.35 GHz (UNII-2), and 5.725–-
5.825 GHz (UNII-3); 12 channels
●
5. 47–-5.725 GHz; 11 channels
ETSI: (-E)
●
2.412–-2.472 GHz; 13 channels
●
5.15–-5.725 GHz; 19 channels
Japan: (-P)

Rest of World: (-W)
●
Uses IEEE 802.11d to identify band ranges and channels
Support mode
●
IEEE 802.11a
●
IEEE 802.11b/g
●
Autosensing, IEEE 802.11b/g preferred over IEEE 802.11a
●
Autosensing, IEEE 802.11a preferred over IEEE 802.11b/g
●
Received signal strength indicator (RSSI) (default)
Data rates
IEEE 802.11a:
6, 9, 12, 18, 24, 36, 48, and
54 Mbps
54 Mbps
IEEE 802.11b:
1, 2, 5.5, and 11 Mbps
IEEE 802.11g:
6, 9, 12, 18, 24, 36, 48, and 54 Mbps
Nonoverlapping channels
●
IEEE 802.11a: Up to 23 (including radar channels)
●
IEEE 802.11b/g: 3 (Japan uses 4)
(Bluetooth 2.0 also uses the 2.4-GHz spectrum, so IEEE 802.11a is recommended when using Bluetooth 2.0)
