If and When the grid fails (for any reason) Don't worry about your
service as there will be no Internet and only antique cars on the roads
as long as they have gas.
Solar panels? Gone with all solid state devices. Computers? Likely fried
as well as all the new fancy ham gear.
We'll be more interested in food and staying alive than the Internet.
Add staying warm to that. Old 2 and 3 tube QRP rigs will be the most
reliable.
The old Collins and Hallicrafters equipment will likely still work, but
those old rigs we power hungry even in standby. Certainly not the choice
for running when power is limited.
As to on topic, the article has many inaccuracies. Fiber is not limited
to anywhere near a gigabit. Rather than Gbs it should make close to GBs
or faster Cables used for cable TV can beat the Gbs limit with many 100
Mbs and many more slower connections connections running
simultaneously. I'd take tha article with a heaping spoon of salt,
rather than a grain.
Speed limits on any service except dial-up are mainly limited by the
equipment at each end.
IF this system is based on previous information, a coating on the high
tension lines acts like a wave guide.
I find good old cat 5 to be far better than the best WiFi offered. They
get to gigabit speeds by adding the limits of all three possible
frequencies. How fast they are in reality is much slower. I'm in a
rural subdivision and can see at least 7 or 8 networks. That limits my
speed on WiFi to less than half the advertised rate. Usually it's only a
quarter.

I heard them talking about this on the radio today.
They specifically referred to "clamping on the existing
power lines".
The whole idea is to leverage the existing infrastructure.
Of course, when the grid goes down it will take this with it.
They also mentioned that it had been tried before but that
they "Had it right this time".
We need to know the frequencies they'll inject, the filtering
of every device they will use/allow (including cheap Chinese
devices the FCC/FTC allows to be imported), and how quickly
and effectively will be remediation of interference.
We need to put our elected officials on notice that we will
hold them accountable if they allow this to interfere with
emergency communications and other legal uses of spectrum.
We will follow the money to know who is selling US out.
Some dope who wants to watch idiotic movies via the internet
is not a good reason to splatter RFI across America.
If it's as bad as the previous efforts it may as well become
known as "ATT's EMP".

This from the ATT press release scares me...
“We think this product is eventually one that could actually serve
anywhere near a power line,” said Marachel Knight, AT&T’s senior vice
president of wireless network architecture and design, in an interview."
"near the power line" not via the power line...
73s and thanks,
