wap power

Unanswered Question

What wap commands affect the radio transmit power ? Is it

power local cck

power local ofdm

Are these the "B" and "G" settings?

Also what is the command for the "A" radio power settings ?

I have this problem too.

Hi Glen,

Good question! I'm sure Scott and others here will weigh in on this :)

**power local cck (relates to b clients)

**power local ofdm (relates to g clients)

Are these the "B" and "G" settings? (yes)

Also what is the command for the "A" radio power settings ? (power local)

power local

Use the power local configuration interface command to configure the access point or bridge radio power level. Use the no form of the command to reset the parameter to defaults. 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.

2.4-GHz Access Point Radio (802.11b)

[no] power local {1 | 5 | 20 | 30 | 50 | 100 | maximum}3

2.4-GHz Access Point Radio (802.11g)

[no] power local cck {1 | 5 | 10 | 20 | 30 | 50 | 100 | maximum}1

[no] power local cck {-1 | 2 | 5 | 8 | 11 | 14 | 15 | 17 | 20 | maximum}4

[no] power local ofdm {1 | 5 | 10 | 20 | 30 | maximum}1

[no] power local ofdm {-1 | 2 | 5 | 8 | 11 | 14 | 17 | maximum}2

5-GHz Access Point Radio (801.11a)

[no] power local {5 | 10 | 20 | 40 | maximum}1

[no] power local { -1 | 2 | 5 | 8 | 11 | 14 | 15 | maximum}2

[no] power local { -1 | 2 | 5 | 8 | 11 | 14 | 15 | 17 | maximum}2

Note The maximum transmit power depends on your regulatory domain and the antenna gain for your access point or bridge. For additional information refer to the "Channels and Antenna Settings" section of the hardware installation guide for your access point or bridge.

Note The supported transmit power levels differ on the various access points and bridges.

Note This command requires the radio to be turned on and enabled to determine valid power settings allowed on your access point radio.

Step 1

configure terminal

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

These options are available for the 802.11b, 2.4-GHz radio:

{ 1 | 5 | 20 | 30 | 50 | 100 | maximum }

These options are available for the 5-GHz radio:

{ 5 | 10 | 20 | 40 | maximum }

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. All settings are in mW.

Note The settings allowed in your regulatory domain might differ from the settings listed here.

Step 4

power local

These options are available for the 802.11g, 2.4-GHz radio:

power local cck settings:

{ 1 | 5 | 10 | 20 | 30 | 50 | 100 | maximum }

power local ofdm settings:

{ 1 | 5 | 10 | 20 | 30 | maximum }

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 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 5

end

Return to privileged EXEC mode.

Step 6
