Re: [time-nuts] GPS through windows
The low-E coatings are known to attenuate WIFI. WIFI is probably a worse case than GPS, but the availability of the gear makes experimenting easy. I think they are sputtered metal either on the glass or on a thin film applied to the glass. Southwall Technology in Palo Alto pioneered or at least commercialized the technology.
Pay-walls on technical journals have to go. The IEEE doesn't pay the author for the article. They used to make the author pay a small fee. Anyway, the exorbitant fees of technical journals discourages cross-discipline research. You can't be a member of every one of these societies.
The US government papers (Department of Energy for instance) are free on the DOE websites, but under a paywall on other government websites. (AKA left hand not talking to the right hand.)
End of soap-box rant.

This is only somewhat on-topic for time-nuts.
NIH requires that all papers that they fund be available (free) via PubMED.
I think they give the original journal 6 months or a year of head start.
The IEEE is particularly behind the times. I assume it's left over from when
they could get away with it because they only had to jack up the price of
printed stuff by a small amount. Some of this may trace back to their
standards work where they could get away with high prices.
Does anybody have the URL for a good FAQ type article on this area?

Actually they are getting worse. IEEEs Computer Society started to send
out yearly reminders that it's not ok to share documents you legaly
acuired with your coworkers and friends. Telling them a few times that
this is in contradiction to local law, which explicitly allows me to do
that didn't change anything... That and also the wording that strongly
suggests that anyone who is subscribed to the CDL is a thief ("illegaly"
copying files and sharing them with the world) led me to the decision
to cancel my subscription.

I'm in astrophysics and arXiv is there just for that.
Why don't others do that?

They are interference filters. Layered coating 1/4 wavelength thick that
send some waves back in phase and other out of phase, they reflect heat and
UV be let light go through. I think it is a tin oxide coating of some
kind.
Sometime they use silver but only on the inside of a double pane window
with the inside filled with inert gas, otherwise the silver tarnishes.
OK, I think they can also over coat the silver with an oxide to keep the
air away from it
I think my windows at home have both. I can see the 1/4 wave coating
change color with the angle I look at the glass, the silver simply darkens
the glass. The argon gas between the panes is for insulation.
I assume it is the metallic silver coat the messes with RF signals. I
think the silver is very common in large buildings. But with a large
building they make the glass custom to the architect's specifications so no
one can know what is in your building.

Both ACM and IEEE are publishers at heart. IEEE likes to boast that they
publish almost a third of the world's technical literature.
It's instructive to look at their annual reports, where sources and uses of
funds are documented. Follow the money, always.

or Indium Tin Oxide (ITO) which is transparent and conductive.

yes.. the german young lady was working with triple pane windows filled
with Argon

A previous employer of mine would not come up with a subscription to IEEE
mags, so I found an alternative: I joined the local university library as
an external borrower. This gave me a login to all the electronic mags that
the library subscribed to, unfortunately it only worked inside the
library's firewall, but I was able to download articles onto a USB stick.
Days of reading fun for $120!

"A group of experts has urged funders of UK research to encourage
