is "client power management" understood by non-Cisco cards?

I would like to tailor the "power client" IOS command to instruct WiFi adapters to limit their max transmiting power.

Will this be understood by non-cisco cards? In other words: is this a standard 802.11 power management command?

I am a little bit confused, because the documentation says that in order to use this command, "Aironet extensions" must be enabled....

The key is the card. I believe the 2200 is only CCXv3, but according to the following link DTPC was added in CCXv2, so you should be fine.

To compare, here is the page showing HPs with 2200s as being CCXv3.

Re: is "client power management" understood by non-Cisco cards?

What you are describing is often referred to as DTPC (Dynamic power control or Dynamic transmit power control). The following link shows the syntax for it. It only works with clients that support DTPC. This is a capability of clients that support CCX (v4 I believe). Most modern client adapters support CCX, as long as you are using their client software (such as ProSet for Intel). If you tell us what cards you have I can try to find if they support CCX and DTPC.

Re: is "client power management" understood by non-Cisco cards?

Hello Eric:

Mostly HP Pavillion dv1135 with on-board Intel(R) PRO/Wireless 2200BG adapters.

I do not see these laptops as compatible in the Cisco CCX page.

However, other machines from HP (specifically, HP Compaq laptops) with the same adapter do match the CCX v4 spec. It is strange not to see the Pavillions in the list.

Any pointers will be greatly appreciated.

Best regards, Rogelio

Thank you very much for your response, Eric.

Now I have to research how I could verify that the client is actually obeying the access point request for some specific max transmit power. But that is another problem ;-)

Intel recently upgraded their wireless drivers. You may want to review if a driver refresh is appropriate for your project:
