If you're in the EU, I contributed a fix that has not yet made it into

difficult, there are so many caveats!).
Technically, it's cfg80211 code; the reason that it's not in yet is that
I'm unsure about the legal situation of the ETSI and the national
bodies, it seems to me that the ultimate decision is done by the
national bodies and last I heard France had quite different restrictions
than Germany, for example.
OK, sorry about the naming mixup, you are, of course, correct. I have
not really got to grips with how all these different sub-systems fit
together. I also see that the mac80211 and cfg80211 changes that are in
Fedora have not made it into mainline 2.6.25, so I assume it will go
into 2.6.26?
Does anyone have that info? I can dig up the info for Germany easily
(the "Frequenznutzungsplan" is available on the regulatory agency web
site as pdf)
Here is a link that came from the Wikipedia page I mentioned in my post:
http://www.arcep.fr/index.php?id=8571&L=1&tx_gsactualite_pi1%5Buid%5D=232&tx_gsactualite_pi1%5Bannee%5D=2003&tx_gsactualite_pi1%5Btheme%5D=0&tx_gsactualite_pi1%5Bmotscle%5D=&tx_gsactualite_pi1%5BbackID%5D=2122&cHash=a558568045
This document applies to the list of 58 departements shown. It says that
with these departments all channels may be used indoors at +20dBm
(100mW). Outdoors +10dBm (10mW) is allowed on all channels but below
2454MHz +20dBm (100mW) is allowed. Another quick check shows that there
are 100 departements in France. Also note that this dates from 2002 and
states that new lists of departements will be published in 2003 and
2004, so presumably the number of departements will have increased by now.
I can't imagine how this regulatory mess is enforceable or how any other
OS/hardware combination does it. I'll have to say that I work for a
company that produces Wi-Fi chips and products based on them and that we
find the whole regulatory situation worldwide just as confusing as
everyone else does.
A complete country/regulatory map is going to be very difficult to
research and implement, I assume that we can't go far wrong if we used
something like the Intel EEPROM contents as a guide to what can be done?
I assume that local infrastructure will comply with local restrictions,
so it's mainly IBSS use that needs controlling. And power output, which
could be difficult if we need to know whether we're outdoors or not.
Comments folks?
