Tweaking with Firmware increases output power (mw) ?

destumbler · 01-12-2003

Hi !

Does anyone know if the output power in mw is "limited" by firmware or by hardware ? I've got a ELSA Airlancer (same as Orinoco Gold) and just wanted to know..

Thanks

You cant tweak the output on your card. It is a design of the chip, not software.
Orinoco's and all the Agere based cards are only putting out about 30mw, the first series of Cisco cards were the same. now the new 352 series are at 100mw.

Really? 100mw? If only I had waited. Have new orinoco cards been increased at all?

This is not entirely accurate. Due to different countries regulatory constraints, you'll find that the same card can only output a certain amount of power when set/sold in a part¡cular country/region. For example, the Cisco 350 series can output up to 100mW, but in some EU countries this is limited to 50mW, and to 30mW in others. This maximum power output, along with many other "interesting" settings, are written in the card's PDA, when the manufacturer burns the firmware to it. It is possible (without having the manufacturer do it) to load a new PDA into some cards, namely Prism2 cards, with changed items such as MAC address, regulatory domain (allow all 14 channels, for example), etc.

It is true that some cards will only do 30mW or so by design, and it's not possible to up the power on those.

Cheers,

It's all in-house research

I've cloned firmware from one card to another, changed MAC addresses, modded for all 14 channels, etc. - there are tools out there that will allow this. I'm not going to post a FAQ or tutorial on this, as it's likely you'll turn a card or two into bricks, so unless you're prepared for that, it's not adviseable to try. If you look around, you'll find Intersil test software, as well as a couple of firmware updaters that can also dump the card's firmware into a file.

Cheers,

Mother
