It has low power indoor (LPI) and very low power (VLP) modes. The pluggable transceiver could be color coded to a chanspec, then the four color map problem can be used by installers per those chanspecs. https://en.wikipedia.org/wiki/Four_color_theorem There is no CTS with microwave "interference" The high-speed PHY rates combined with low-density AP/STA ratios, ideally 1/1, decrease the probability of time signal superpositions. The goal with wireless isn't high densities but to unleash humans. A bunch of humans stuck in a dog park isn't really being unleashed. It's the ability to move from block to block so-to-speak. FiWi is cheaper than sidewalks, sanitation systems, etc. The goal now is very low latency. Higher phy rates can achieve that and leave the medium free the vast most of the time and shut down the RRH too. Engineering extra capacity by orders of magnitude is better than AQM. This has been the case in data centers for decades. Congestion? Add a zero (or multiple by 10) Note: None of this is done. This is a 5-10 year project with zero engineering resources assigned.
