Incorrect frenquency table for France and 802.11h support

Reported by: Assigned to: mrenzmann (accepted)
Priority: minor Milestone: version 1.0.0 - first stable release
Component: madwifi: HAL Version: trunk
Keywords: countrycode frenquency France 802.11h Cc:
Patch is attached: 0 Pending:


Hi, and first, thanks for your great job.

There are new frenquency freely usable in France.

  • Channels in the range 5150-5350 are for indoor use only (200mw Max)
  • Channels in the range 5470-5725 Mhz can now be used outdoor without authorization :
    • TXpower must be limited to 1W if hardware is using TPC (3dB avg atenuation) or 500mW (3dB attenuation) without TPC.
    • Hardware must use DFS.

So i wonder if this the the right place ask for an HAL update for France country table ? And if someone could give me more information about state of 802.11h (TPC/DFS) support in madwifi -ng

I'm using madwifi-ng :

wifi0: Atheros 5212: mem=0xe5000000, irq=11

with theses parameters :

autocreate=none countrycode=0xfa outdoor=1 xchanmode=1

and i obtain these usable channels :

ath1      35 channels in total; available frequencies :
          Channel 01 : 2.412 GHz
          Channel 02 : 2.417 GHz
          Channel 03 : 2.422 GHz
          Channel 04 : 2.427 GHz
          Channel 05 : 2.432 GHz
          Channel 06 : 2.437 GHz
          Channel 07 : 2.442 GHz
          Channel 08 : 2.447 GHz
          Channel 09 : 2.452 GHz
          Channel 10 : 2.457 GHz
          Channel 11 : 2.462 GHz
          Channel 12 : 2.467 GHz
          Channel 13 : 2.472 GHz
          Channel 36 : 5.18 GHz
          Channel 40 : 5.2 GHz
          Channel 44 : 5.22 GHz
          Channel 48 : 5.24 GHz
          Channel 52 : 5.26 GHz
          Channel 56 : 5.28 GHz
          Channel 60 : 5.3 GHz
          Channel 64 : 5.32 GHz

which are the same that in :



PS: Links to the offical documents (in french). (ARCEP is then French Authority who decides about frenquency usage)

As most of theses decisions were based on european-commission recommendations, i guess this will affect also other european coutries.

  • priority changed from major to minor.
  • status changed from new to assigned.
  • type changed from defect to enhancement.
  • owner set to mrenzmann.
  • milestone set to version 1.0.0 - first stable release.

Yes, this is the right place for such a request, since this can be regarded either as a task or enhancement to the driver. I will forward this request to Atheros next time I communicate with them.
