I did some consulting work for a big Canadian telco, a project to monetize their cell tower data.

It was obviously all tokenized. Not sure if there was any restrictions on who could buy it, but use cases were mostly about knowing how many people were in a certain area (e.g. an outdoor space) and how long they stayed there (e.g. to properly price the cost of billboards).

It's pretty common, afaik, to measure how many pairs of eyes can potential see adverts.
