The iPhone is about to have an Ultra-wideband coprocessor 👀👀  https://www.macrumors.com/2019/09/09/rose-r1-coprocessor-2019-iphones/ 

For positioning, UWB is much superior to current iBeacon and bluetooth tech — this is 10cm accuracy. But the use case described here makes me believe this isn't just a receiver, but a transmitter too. This just changed what a Tile-like product, and the iPhone mesh, means.

A 'Rose' coprocessor may be that 'more powerful chip' described in the January reporting about a laser scanner. True AR chip.  https://www.bloomberg.com/news/articles/2019-01-30/apple-is-said-to-prep-new-3-d-camera-for-2020-iphones-in-ar-push 

UWB has never really been used to its full potential. It was restricted to military applications in the U.S. until 2002. UWB radar may prove better than LIDAR for self-driving cars, and better than ultrasound in medical imaging.  https://www.vice.com/en_us/article/3k5jen/this-1960s-radar-technology-is-making-a-comeback-in-self-driving-cars-vayyar-ces 

Having an UWB transceiver in your iPhone, Watch, AirPods, and Wallet may also be hugely valuable for pedestrian identification when the self-driving cars hit. @rabois predicted that.
