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.
