I did the cellphone module for the EO PDAs back when there was just the "A" and the "B" ('Bell') carriers. I recall reading academic papers at the time pointing out that, technically, it would be most efficient to have a single swath of bandwidth assigned to a single company; instead, half went to 'A' and half went to 'B' -- guaranteeing a suboptimal technical solution. It's interesting to me that, at the time, they were able to get away with only 2 carriers per region.
- Aloha 7y agoAMPS was designed prior to divestiture being a thing, but even with that in mind, no one really knew how fast cellular usage would take off, and so the carriers were caught somewhat flatfooted. Consider that most cellular networks were originally built with omni antennas, not panel antennas, so the ability to reuse channels and channel-per-site density was noticeably lower.
