most have been decommissioned, but a lot more of these than you'd think are still actively serving more remote areas, just with newer radios downstairs

this is from a tool I wrote to load and query the fcc microwave license database from google earth, looking at att/mtn bell/us west/qwest/centurylink's network in western colorado, where it's often cheaper to maintain and occasionally build relay sites than drag fiber through the mountains (also they may serve as a backup to fiber if a cut means waiting a day or two for the snowmobiles and helicopters to find and fix it)

compare to nebraska/iowa where it's easy to just put the fiber in the ground in a straight line:

(green = active license, red = cancelled/expired)

I went to work in a smaller central office a few months ago and got to spend part of my afternoon talking with a tech who'd worked on and around them for a couple decades, which was pretty awesome. fun facts: the waveguides (they use plumbing instead of cables) are about 1:2 rectangular, so you can easily and efficiently switch out/multiplex polarized 6/12GHz radios. those horns give you an effective spot size of like 30something degrees, so you have to use a fuckload of transmit power to hit those 40+ mile links. and to handle things like obstructions and elevation changes, they use 'passive repeaters' (big metal panels) to reflect the signals around:




in conclusion, the best ssid is WLA697

neat, thanks!

this thread reminds me of the dude on reddit who got the cops called on him and fired from his job because he thought it was a good idea to name his wifi hotspot "Bomb Detonator" at a tech conference
