Chapter 6 Configuring Radio Settings
Configuring Radio Transmit Power
Use the
no
form of the power command to return the power setting to
maximum
, the default setting.
Limiting the Power Level for Associated Client Devices
You can also limit the power level on client devices that associate to the wireless device. When a client
device associates to the wireless device, the wireless device sends the maximum power level setting to
the client.
Note
Cisco AVVID documentation uses the term Dynamic Power Control (DTPC) to refer to limiting the
power level on associated client devices.
Beginning in privileged EXEC mode, follow these steps to specify a maximum allowed power setting on
all client devices that associate to the wireless device:

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 transmits at up to 100 mW 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 3050 mW.
