Very good read!

As mentioned, Wi-Fi 6 seems to be borrowing quite a bit from cellular technology - OFDMA, BSS coloring (~ Cellular Base Station Code), TWT (~paging channel for indicating to mobiles when to wake up to look for incoming call or data) etc., and rightly so.

As Wi-Fi networks get more and more dense, they start appearing more and more similar to cellular networks and best practices from either one need to be cross pollinated! This may become even more relevant in the coming times when we have technologies like 5G & Wi-Fi-6 competing for their share of IOT devices.
