They started installing poles along a main road near where we live and I’m not sure what the white antennas on them are for. Some of the poles have traffic cameras like the one in the picture but others don’t. They are spaced every half to one mile and have antennas on opposite sides, with what looks like a radio cabinet near the base. The antennas are all aligned along the road, pointing parallel to traffic. This is in southwest Pennsylvania.

    big ol ubiquiti mesh network. many towns are covered in them. iirc ubiquiti made a name for themselves doing wireless in stadiums… had some solid firewalls/routers

    the new stuff is pretty at least

          No bro. A mesh network is a bunch of access points that repeat each others signals. This is like a single cable, but using RF. It is not an access point.

              This is the wireless equivalent of a single Ethernet cable. if you follow each of the dish pairs in a roughly straight line, you will hit another transceiver. This pole would be middle three nodes of this:

              (Air Fiber) <-------> (Air Fiber) (switch) (Air Fiber) <--------> (Air Fiber)

              Camera could also be plugged into the switch.

              And yes, if a car impacts the pole, you lose that point to point link. Hope you got a failover plan or another set of air fibers that take a different path.

                  Forgive my ignorance in that case. I did very poorly on the unit that covered token ring, and was in perpetual self doubt because I got an answer wrong when I referenced the original manufacturer document instead of the slides.

                  Nothing against the protocol, I just didn’t learn it properly and was born too late to see it in person. (I love learning about all tech)

                  It is not using token ring protocol. It is a wireless implementation of the Ethernet protocol. I don’t think you fully understand what token ring is, or we’re not doing a good job of explaining what a point-to-point radio is.
