The speaker in the video Richard Lansdowne - LoRa Geolocation mentions straight-off that he won't be quoting an accuracy for geolocation using LoRa, and it's of course not the ideal signal you would use.

A comment below the video says:

Excellent Richard, you nailed it! You've succinctly described the IoT asset tracking problem and what we need to do going forward to make this real.

So far I can't figure out, at least from the video, how this might actually be done using standard LoRa and perhaps LoRa-WAN. How would LoRa protocol estimate distance in order to triangulate, assuming that's how this works? What would be an approximate best-case accuracy based on hardware limitations? (of course your milage may vary)

    In the same way as any other radio based reverse triangulation works, presumably. – Sean Houlihane Nov 13 '18 at 12:26

    @SeanHoulihane I don't understand why you would say that. There are many, very different ways that a radio system can estimate distance. You could say they are all the same only until you look into the details. Considering how low bandwidth and spartan the LoRa architecture is, getting an accurate estimate of distance is particularly challenging. – uhoh Nov 13 '18 at 13:20
