Erm, ever work on one? it's extremely unusual to find a backhaul to a store and forward system that ain't got one backhoe-ready day-ruiner.
"You guys really need a diversity link for that." They almost never do.... although to be fair, it's usually not that hard to add one after the fact. These days, a wireless backhaul is very easy and not that much money.
There was a gas station in Plano I finally stopped going to after they were down for three visits in a row over a three week period. I bet it was a $50 to $100k a day station ( 20 fueling points, always busy ) made useless by a "business class" DSL backhaul with no doubt lousy media... I looked - it was a DSL modem.
Hopefully.
Then yer mom! :)
I am just making idle conversation. There's no "attitude" here.
yes, there is. A meter reader outage is much smaller than the Big Concentrator going down.
I dunno - do you have cable? I bet it's close to 1% outage annually, and that's something we pay more for than what an AMR node could afford.

Not sure.
yeah, could be. Still... union meter readers? Oy. I did not know that.
I would not be surprised if there were a complete spectrum of such experts... a consultant is somebody you hire to tell you what you want to hear.
That was the figure for the non-wireless Itron system ( which looked like the only one that met spec ) on the PDF I linked to. 17 years.
If it goes into wider deployment, then yeah - I bet that bends the cost curve a little. Depends on how nimble the vendor is.
Well it was done like you said 40 + years ago and likely much earlier. Wikipedia shows that was done for most of a century. Most everyone has converted to 240 V or 480 V normal circuits. I was an inspector for such a conversion project about 15 years ago. It was supposed to be the last one in the Lost Angeles area. There is probably some still out there in the rural areas of California. The antifuse was in how the ballast operated, it was fed from a series to multiple transformer.
Wiki doesn't say that, but given the obvious advantages for bugs, I wouldn't be at all surprised. They invented bouncing laser beams off embassy windows to pick up conversations inside.

That's irrelevant, though. No data is lost because of that "outage". This isn't a telephone network rather more of a data network. BTW, this is one area where a RF system would be better (not that it really matters).
Probably the CIA was doing similar stuff. Hey, the Chinese were naive enough to have a presidential 767 outfitted by a Texas company a few years ago and they discovered dozens of highly sophisticated bugs were installed at no extra cost. Maybe they didn't find them all!
So many gas stations had a satellite link for their credit card processing -- marked by a rectanguloid satellite dish with a seemingly low tilt angle. But that likely went out twice a year from the solar transit, assuming nothing catastrophic happened to the satellite.
