Subject: wireless-regdb: Update regulatory rules for Germany (DE) on 5GHz

Hi,

In Europe ETSI standardized the used for short range devices (SRD) [1] in ETSI
EN 300 440-1 [2].
According to this standard generic use equipment is allowed to transmit in the
frequency range form 5725 MHz to 5875 MHz with a maximum output power of
25 mW e.i.r.p. This generic allocation also allows transmission of 802.11
devices.

[3] has a list of countries and their status about the implementation of the
SRD frequency bands. For the 5 GHz band this can be seen on page 38 in the
paragraph ANNEX 1 and the entry Annex j.

Attached is a patch that adds the 5 GHz SRD band to db.txt for Germany.

If it is acceptable I can provide a patch adding the 5 GHz SRD band for the
other countries listed in [3].

Thanks,
Maxi

Ah, the references to those specs bring back memories of good times with
the European Tourism and Sightseeing Institute in the 90ies :) I
remember heated (but friendly) discussions in RES 8 about 300 674 for
years before it finally was published

Anyway, 300 674 is for vehicle transponder systems. I.e. electronic
toll collection etc. I don't think it's relevant to the regdb in any
way.

The generic SRDs covered by 300 440 are more relevant. But this is
still not a license regulation. It can probably be used as a harmonized
standard with reference to the Radio Equipment Directive, but licensing
is not in the scope AFAIK. Spectrum utilization is not fully harmonized
in the EU. So you have to look at the national regulations for every
country, even within the EU.

The ERC recommendation Maximilian linked to (
http://www.erodocdb.dk/Docs/doc98/official/pdf/REC7003e.pdf ) is much
more useful, since it is a collection of SRD licensing rules for all
CEPT countries. Which are much more than "just" the EU - 48 countries
now, according to http://cept.org/cept

But you'll still have to look into the actual national regulations. In
my experience, the listed restrictions and conditions in appendix 3 of
ERC/REC 70-03 are often imprecise or incomplete. It's definitely best
to do what you did: Talk to the local regulatory authorities. I'm sure
most of them are more then interested in helping to improve the regdb.

Thanks for the response! I'll be sure to ask the CRC why do they reference 300
674 in the _Generic_ 5725-5875 MHz SRD section of list of devices that use
EU-harmonised frequency bands and what's the status of 300 440-1.

Hello,

Just to add my input to this thread. I've previously contributed the SRD ranges
for Bulgaria, hopefully this info will provide pointers for research in other EU
countries. Since then I've doublechecked the standards situation for Wi-Fi with
the local communications regulation commission and one of the staffers there has
given me an expert opinion (I would attach it, but it's a nasty HTML email in
Bulgarian, if there's interest, I'd be glad to share and translate it).

The gist on the SRDs is that in Bulgaria they fall under the following
standards (which correspond to ETSI standards):

BDS EN 300 440-2[0]
BDS EN 300 674-2-2[1]

Note that the first one is a harmonized standard (so in theory it should be
universally adopted accross the EU) and the second one is a candidate harmonized
standard (so you should check if it's already been adopted locally).

As far as I could tell, BDS EN 300 674-2-2 defines the maximum e.i.r.p. for the
SRD range but someone more knowledgable should take a look, too.

One thing that they did not mention is that there's a BDS EN 300 440-1[2] that
does indeed also specify the max e.i.r.p. but I've reached this through my own
research and did not get this info from anybody affilliated with the CRC.

Also, note that the EN 300 440-1[3] still does NOT seem to be a harmonized standard
(again, probably one should check if it has been adopted locally).
