I've posted on some other topics here and have had some great discussions. In those other posts, I've emphasized that I'm not a techie and need basic civilian explanations. This is somewhat different, because I have a background as a retired telecom analyst who specialized in broadband local access. When it comes to this stuff, I can probably go toe-to-toe in the acronym-slinging department. We shall see. LOL For a while, I was one of the go-to analysts on Wall Street for all things DSL, along with what was at the time emerging wireless transmission in the local access (a/k/a "last mile") network. But time has passed, so I'd be interested in getting up to speed on the changes since I retired 18 years ago. In particular, 5G and the wireless side of what Google was calling their fiber project some time back until they realized that metropolitan fiber would be way too expensive to pay off. When I was doing my thing, the DSLAMs were increasingly fiber-fed, and then connected to DSL for the local twisted pair drops. Now I'm wondering what might have happened on using wireless for those final drops. I live in a rural area, with some feeder network fiber. The county gov't is surprisingly competent for a rural county, and I hope to get some ideas to pass along to one of the officials here who's interested in expanding broadband connectivity here. I'm going to keep this intro pretty short, pending discussions. Most of the tech talk here and elsewhere tends to focus on the higher layers of the OSI stack, while transmission is generally in the lower layers. Those with lower-layer knowledge and experience would be especially welcome to weigh in on what I hope winds up being an interesting and productive discussion. Thanks much in advance.
