AT&T’s Abandoned Microwave Tower Network (2017)

Source: Hacker News

Article note: The old Bell system was truly a marvel. The fact that a nation-wide, circuit-switched, analog network with free-air microwave links worked is borderline-miracle. The fact that it was comprised of technologies invented in-house that were engineered until they had 50-year service lives before being deployed is completely foreign to the modern technology context. ...and now we're letting the abusive monopoly business part reassemble itself _without_ the benefit of running a civilization altering science and engineering lab.
