[Madwifi-devel] Maximum txpower for regdomain Germany

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hello,

according to http://www.nuclearcat.com/athmap.txt the maximum txpower
(EIRP) in 
Germany are:

2.4GHz: 18 dBm (63 mW)
5.1GHz - 5.3GHz: 16 dBm (39mW)
5.5GHz - 5.7GHz: 17 dBm (50mW)

According to the german netagency  (Bundesnetzagentur) the maximum
txpowers (EIRP) are

http://www.bundesnetzagentur.de/media/archive/313.pdf:
2.4GHz: 20 dBm (100mW) 

http://www.bundesnetzagentur.de/media/archive/5009.pdf:
5.15GHz - 5.25GHz: 23dBm (200mW)
5.25GHz - 5.35GHz: 23dBm (200mW)  with a penalty of 3dBm if no TPC is
implemented
5.47GHz - 5.72GHz: 40dBm (1000mW) with a penalty of 3dBm if no TPC is
implemented

My Wistron CM9 Cards just allow me to set the txpower to 16 dBm with
2.4GHz when i
use madwifi 0.9.2 (hal 0.9.17.2)

          Current Tx-Power=16 dBm       (39 mW)

With an old version of the driver i'm able to use a maximum txpower of
19dBm:

~ # iwlist ath1 txpower
ath1      unknown transmit-power information.

          Current Tx-Power=19 dBm       (79 mW)

The maximum txpower seems to be a deliberate value of the atheros HAL,
probably based on wrong
informations.

Could somebody forward the above information to the right people (the
maintainer of athmap.txt and atheros) 
or would an enhancement ticket be the proper way?
