Chapter 2 Configuring Radio Settings

Configuring Radio Transmit Power

Beginning in privileged EXEC mode, follow these steps to set the transmit power on access point radios:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	interface dot11radio { 0 1 }	Enter interface configuration mode for the radio interface. The
		2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.
Step 3
	power local	Set the transmit power for the 802.11g, 2.4-GHz radio to one of
	power settings should be:	the power levels allowed in your regulatory domain. All
		settings are in mW.
	{3 4 5 6 7 10 13 15 17 18
		On the 2.4-GHz, 802.11g radio, you can set Orthogonal
	20 maximum}	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 30 mW.
Step 4
	end	Return to privileged EXEC mode.
Step 5
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

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:
	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	interface dot11radio { 0 1 }	Enter interface configuration mode for the radio interface. The
		2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.
