Chapter 6 Configuring Radio Settings
Configuring Radio Transmit Power
Beginning in privileged EXEC mode, follow these steps to set the transmit power on access point radios:
Use the no form of the power command to return the power setting to maximum, the default setting.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface dot11radio {0 | 1slot/port} Enter interface configuration mode for the radio interface.
The 2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.
The 2.4-GHz 802.11n radio is 0, and the 5-GHz 802.11n radio
is 1
Step 3
power local
These options are available for the
802.11a, 5-GHz radio (in dBm), and
for the 2.4-GHz 802.11n radio (in
dBM):
• On 1130 and 1240 series APs:
{-1 | 2 | 5 | 8 | 11 | 14 | 17 | 20}
• On APs with 802.11n MIMO
radios (such as 2600, 3600):
{22 | 19 | 16 | 13 | 10 | 7 | 4}
Set the transmit power for the 802.11b, 2.4-GHz radio or the
5-GHz radio to one of the power levels allowed in your
regulatory domain.
Note See the hardware installation guide for your access
point to determine the power settings for your
regulatory domain.
Step 4
power local
These options are available for the
802.11g, 2.4-GHz radio:
power local cck settings:
{ -1 | 2 | 5 | 8 | 11 | 14 | 17 | 20 |
maximum }
power local ofdm settings:
{ -1 | 2 | 5 | 8 | 11 | 14 | 17 |maximum }
Note These options are not
available on 802.11n APs.
Set the transmit power for the 802.11g, 2.4-GHz radio to one of
the power levels allowed in your regulatory domain. Settings
are in dBm.
On the 2.4-GHz, 802.11g radio, you can set Orthogonal
Frequency Division Multiplexing (OFDM) power levels and
Complementary Code Keying (CCK) power levels. CCK
modulation is supported by 802.11b and 802.11g devices.
OFDM modulation is supported by 802.11g and 802.11a
devices.
Note See the hardware installation guide for your access
point to determine the power settings for your
regulatory domain.
Note The 802.11g radio maximum transmission power level
depends the AP model. See the AP data sheet for the
power levels.
Step 5
end Return to privileged EXEC mode.
Step 6
