Wouldn't it make more sense to work with the cell service providers? Surely at least some people turn off location permissions? I would think the cell service providers have much more reliable data.
- wyxuan 7y agoTechnically that data is anonimized, and although its not hard to deanonomize, its not easy to scale
- angry_octet 7y agoThey have cell location data, but could have quite a few people in it. They already have this data, and I would guess that they find it useless for contact tracing. In contrast, Google/Apple and to some degree fb have super accurate traces of exactly which shops and offices you went to.
- kanox 7y ago> I would think the cell service providers have much more reliable data. Google tracks location history from GPS and this is accurate to at most a few meters and it can be use to check if people walked by each other on the street. As far as I know phone service providers don't have anything similar. The cell you're connected to can cover an entire neighborhood.
