summary of the talk, by AndroidAuthority: "Basically, Wi-Fi-based positioning has a lot of benefits over other positioning technologies. Wi-Fi-based positioning offers a superior link budget, has lots of available spectrum to meet growing demand, is compatible with previous generations of Wi-Fi, is scalable to a large number of clients, is adaptive to traffic conditions, is robust to multipath through MIMO, is secure, and is cost effective. Sure Wi-Fi Ranging is slightly less accurate than UWB and Bluetooth Channel Sounding, but it has better range than both."
