I don't get it. Wouldn't it just be easier to install more base stations with a lower transmission strength (essentially leveraging the same transmission frequ

  I can think of at least two reasons why this is superior: 1) You need to have multiple base stations installed roughly equally spaced. This seems to support heterogenous spacing of the stations 2) With lots of low-powered base-stations interference and obstructions start to become bigger issues. With many reachable antennas, a small fraction that have interference or obstructions should merely decrease SNR a bit rather than drop completely. Of course advantage #2 seems (to me) to be theoretical; I'd like to see how this performs in the real-world. The other issue I can see is moving receivers and/or moving reflectors. Imagine having this work, for example, when you are near a wind-farm, with many moving reflectors changing the apparent signal strength continuously. I know someone who worked on a similar problem in the past, and temporal coherence in real-world situations was close enough to the feasible round-trip delay to the data-center. (e.g. if you need to recalculate every 150ms and it takes 125ms round-trip to the data center, you only get 1/6 the theoretical benefit).
