[Cerowrt-devel] this was a pretty comprehensive guide to how the 5.x spectrum is actually used

http://apps.fcc.gov/ecfs/document/view?id=7022123531

starting at section 2.82 around page 27.

based on this, I am inclined to drop the "just fix the weather radars"
idea from the fcc comment letter. But a bit more thought and analysis
is needed, as to what infringes on th existing bands or not....

This one talked about DFS compliance.

	This is pretty rotten, instead of simply harmonizing the regulations world wide, they obviously went for requiring DRM and country codes. As if DVD Blue Ray had not amply proven that that does not work. It would be arguably a better solution to exempt devices from these draconian regulations that simply left the disputed frequencies alone (say by a hardware filter so can only be overridden by soldering). The whole thing is pretty funny when it pretends the solution would be to either impose country regulatory requirements by IP-geolocation or GPS (*). As if both methods were anything close to tamper proof. Not that it matters much I would simply go with heavy fines for people (purposefully) using devices outside of the regulation permitted parameters. In the end the proposed schemes also need a enforcement department and fines to back it up, so why do all the pseudo-technical DRM-done-wrong stuff beforehand… (Especially puzzling why DRM since the radar interference sources seem to allow “triangulating” the source close enough to send in the RF-compliance monitoring vans)


(*) on the other hand a mandatory GPS receiver in each wlan router should finally settle the getting the correct time in devices without a RTC ;)

I don't see how this would work anyway, there is no GPS signal where most 
people place their gateways.

As deeply as I/we care about this stuff... I'd intended the last week
and this one to be a vacation before
starting work in berlin on make-wifi-fast. Since the deadline is still
a ways off, can I encourage y'all to work on the document directly,
adding content such as this?

I'd booked a studio this week to lay down some tracks and resuscitate
my right brain. This track had a few good ideas from the cellist in
it, but fell apart, and needs to get completely reworked starting with
a drum track, and most of the middle lyrics are going to get deleted
in favor of improvisation.

And - unless I want to fuel the anger - reading email right now isn't helping.
