Chapter 2 Cisco IOS Commands for Access Points and Bridges
power local
Syntax Description
Defaults The default local power level is maximum.
Command Modes Configuration interface
Command History
Usage Guidelines Use this command to specify the local transmit power level for the current operating radio channel on
the access point. This command requires the access point radio to be turned on. Lower power levels
reduce the radio cell size and interference between cells. The maximum transmit power for the access
point is limited by the regulatory domain for your country of operation.
On some access point radios, the available transmit power settings vary on a per-channel basis. Prior to using
the power local command, you should set the access point to the desired radio channel. If the access point is
set to scan for the best channel, then the power settings available in the power local command are limited by
the radio channel selected by the access point. You can use the power local ? command to display the available
power settings for that channel.
For the 802.11b, 2.4-GHz access point radio:
1, 5, 20, 30, 50, 100, or maximum

For the 802.11g, 2.4-GHz access point radio:
1, 5, 10, 20, 30, 50, 100, or maximum
1, 2, 5, 8, 11, 14, 15, 17, 20, or maximum

For the 5-GHz access point radio:
5, 10, 20, 40, or maximum

-1, 2, 5, 8, 11, 14, 15, or maximum
2
-1, 2, 5, 8, 11, 14, 15, 17, or maximum

For the 5.8-GHz 1400 series bridge radio:
12, 15, 18, 21, 22, 23, 24, or maximum
2
Specifies access point power setting in mW or in dBm.
Maximum power is regulated by the regulatory domain
for the country of operation and is set during
manufacture of the access point and client device.
Note The maximum power level allowed depends on
the gain of the antenna being used on your
access point or bridge and on your regulatory
domain.
For a list of maximum power levels allowed in each
regulatory domain for the 2.4-GHz radio and the 5-GHz
radio, refer to the “Channels and Antenna Settings”
section in the hardware installation guide for your
access point or bridge.
Note The 802.11g radio transmits at up to 100 mW or
20 dBm for the 1, 2, 5.5, and 11Mbps data rates.
However, for the 6, 9, 12, 18, 24, 36, 48, and
54Mbps data rates, the maximum transmit
power for the 802.11g radio is 30 mW or 17
dBm.
