Re: (perhaps off topic, but) Microwave Towers
Also worth mentioning that AT Canada originated with the Canadian Pacific Railway... CP Railway and Unitel --> AT Canada --> Allstream --> MTS-Allstream --> Zayo I have a GIS dataset with about 90% of the most important hilltop and mountaintop tower sites in WA, BC, OR and ID.

Re: (perhaps off topic, but) Microwave Towers
Microwave radios are the things that break the mold of the incorrect assumption that just because it doesn't make sense to put up more wires to a house you can't have more than one provider. Considering that we've deployed a few wireless systems with less latency, jitter, and downtime than the local incumbent DOCSIS provider. In fact the greatest benefit to wireless microwave systems is the fact that they do not need to follow the right of way. Where wireline and fiberoptics must go through more hubs to get from side of town to the other, wireless is a point to point system with latencies+jitter sub 400 microseconds. No matter how great the incumbent fiber/dsl/coaxial network becomes, there will always be new microwave links going up. For their biggest strengths there's no replacement. Now, their weaknesses may be many, and may be apparent, their stengths just outweigh those.

Re: (perhaps off topic, but) Microwave Towers
No idea where you were at, but lots of big companies have done microwave and lots of new companies do microwave. https://en.wikipedia.org/wiki/MCI_Communications MCI was founded as Microwave Communications, Inc. on October 3, 1963 with John D. Goeken being named the company's first president. The initial business plan was for the company to build a series of microwave relay stations between Chicago, Illinois and St. Louis, Missouri. The relay stations would then be used to interface with limited-range two-way radios used by truckers along U.S. Route 66 or by barges on the Illinois Waterway. https://en.wikipedia.org/wiki/Sprint_Corporation Southern Pacific maintained an extensive microwave communications system along its rights-of-way that the railroad used for internal communications. AT had a bunch and I think a couple sites are still active: http://long-lines.net/ Western Union had a microwave network as well. Lots of companies build microwave for internal communications. Rail and utility companies are big here. All of the cell companies do some microwave in their more rural areas.

Re: (perhaps off topic, but) Microwave Towers
We had a ton of point to point wireless customers at 120E Van Buren out to South Mountain. About 10 years ago there was a significant shortage of fiber outside of Phoenix. You choices were SRP and Cox for the most part and SRP at that time had a very limited fiber network. They were actually the only company that offered dark Fiber out to Chandler when that campus first got built.

Re: (perhaps off topic, but) Microwave Towers
I was going to say... in my experience (I've been to a lot of the Arizona electronics sites, having grown up around broadcasting) that most of the microwave equipment in use was for Bell. That was by far the most populous tower on any mountain top. The broadcasters don't send their signals anywhere but either from downtown to the transmiter or in some cases from the big town to a small town to feed a local low power transmitter (like 5kw VHF as opposed to the normal 100kw). Anything else was Satelite. I know the railroad did some wireless (Sprint's towers were also quite densely packed with directional horns) but a lot of their communication for rail signaling was hardwire as far as I was aware. -Wayne On Sat, Jul 14, 2018 at 12:20:34PM -0500, frnk...@iname.com wrote: > Is it possibly AT's old network? > https://99percentinvisible.org/article/vintage-skynet-atts-abandoned-long-lines-microwave-tower-network/ > http://long-lines.net/places-routes/ > > This network runs through our service territory, too.

Not a lot of fiber. If there was, the following wouldn't be needed: https://uto.asu.edu/sun-corridor-network-project-plans-broadband-access-along-i-40 There *are* a number of fiber builds in the area, but none of them are a coherent build across the region.
Re: (perhaps off topic, but) Microwave Towers
Most of these horns are for 6GHz. I have had friends that have "appropriated" some of them by adding a waveguide to N adapter and use them for the 5.8GHz ISM band with some minor aiming.

Re: (perhaps off topic, but) Microwave Towers
There’s a lot less backhoe fade with microwave. ;-) Kidding aside, I’m sure there are plenty of scenarios where microwave makes better sense than fiber especially since it’s a lot easier to clear right of way through the air. Side gig has me maintaining a satellite system. Yes that still makes sense. As part of that I have a service that monitors people applying for microwave transmitters within a few hundred miles. You’d be surprised how many links are applied for every month. -- Keith Stokes Neill Technologies > On Jul 14, 2018, at 9:56 AM, Miles Fidelman > wrote: > > Hi Folks, > > I find myself driving down Route 66.
