[wireless-regdb] NO should be less restrictive

[Robert Grønning]

It seems like NO is wrong according to Norwegian rules

This is how NO currently looks like in wireless-regdb-2011.04.28.tar.bz2
-------------------START-------------------
country NO:
        (2402 - 2482 @ 40), (N/A, 20)
        (5170 - 5250 @ 40), (N/A, 20)
        (5250 - 5330 @ 40), (N/A, 20), DFS
        (5490 - 5710 @ 40), (N/A, 27), DFS
--------------------END--------------------

This is what the Norwegian rules say about general usage of frequencies
for wi-fi:
Note: The following text is a translation from a subsection of the
following document written in Norwegian:
http://www.lovdata.no/for/sf/sd/xd-20090602-0580.html#7
-------------------------------------START--------------------------------------
(3) the frequency band 5150-5350 MHz is authorized for indoor data
transfer
including radio-based local area networks (WAS / RLAN) with a maximum
radiated
power of 200 mW eirp the frequency use defined in the standard EN 301
893 If any
other use than indoor use, the average spectral density in the frequency
band
5150-5350 MHz is limited to 10 mW / MHz eirp in any 1 MHz range.

(4) the frequency band 5470-5725 MHz may be used for data transfer with
maximum
radiated power of 1 W eirp Maximum average spectral density shall not
exceed
50 mW / MHz eirp in any 1 MHz band. The radio equipment shall implement
transmit
power control (TPC) which provides an average attenuation of at least 3
dB. If
TPC is not in use, the maximum allowed radiated power and power density
is 3 dB
lower than that following the first and second sentence. The radio
equipment will
use Dynamic Frequency Selection (DFS) as specified in the standard EN
301 893

(5) The frequency bands 5725-5795 MHz and 5815-5850 MHz for data
transfer with
maximum radiated power of 4 W eirp Maximum average spectral density
shall not
exceed 200 mW / MHz eirp in any 1 MHz band. The radio equipment shall
implement
Dynamic Frequency Selection (DFS) as specified in the standard EN 302
502 Radio
equipment shall transmit power control (TPC) which provides an average
attenuation of at least 3 dB. If TPC is not in use, the maximum allowed
radiated
power and power density is 3 dB lower than that following the first and
second
sentence. On the border between Norway and neighboring power density
shall not
exceed -122.5 dBW / m 2 measured with a reference bandwidth of 1 MHz
unless
otherwise stated in the coordination agreement.

(6) The frequency bands 5725-5795 and 5815-5850 MHz for point-to-point
radio
links with maximum radiated power of 200 W eirp Maximum permitted power
supplied
antenna is 1 W. The maximum average spectral density shall not exceed 10
W / MHz
eirp in any 1 MHz band. The concept of point-to-point radio links
exclude all
forms of point-to-multipoint, omnidirectional systems and transmitters
send the
same information located in the same place (sector antennas). The radio
equipment
shall implement Dynamic Frequency Selection (DFS) as specified in the
standard
EN 302 502 On the border between Norway and neighboring power density
shall not
exceed -122.5 dBW / m 2 measured with a reference bandwidth of 1 MHz
unless
otherwise stated in the coordination agreement.

According to that documentation, NO should probably look like this
instead:
-------------------START-------------------
country NO:
        (2400 - 2483.5 @ 40), (N/A, 20)
        (5150 - 5350 @ 40), (N/A, 23)
        (5470 - 5725 @ 40), (N/A, 27), DFS
--------------------END--------------------

Question 1:
The norwegian laws also says that if TPC is available, then the maximum
allowed TX power
of the 5470 -> 5725 MHz frequency range changes from 27 dBm to 30 dBm, I
don't know how to write that in wireless-regdb.

Question 2:
The norwegian laws for the 5470 -> 5725 MHz frequency range seem to
exceed the European restrictions in 802.11n-2009, I'm guessing that the
upper 5725 MHz frequency needs to be decreased to comply with the
European restrictions? if so, I'm not sure what frequency it should be
decreased to.

Question 3:
The norwegian documentation also mentions these radio frequencies for
wireless data transfer:
* 5725 -> 5795 MHz and 5815-5850 MHz: point-to-point radio links
* 17,1 -> 17,3 GHz:
* 57 -> 66 GHz:
Does these belong in the wireless-regdb as well?

I hope my limited knowlege doesn't cause anyone unreasonable much work,
I'm really trying to get better at this.
