Why would they need Bluetooth permission for?
- greglindahl 6y agoThat's how it can tell you were very close to someone -- all of the other tracking apps do it that way, too.
- hailk 6y agoI'm not familiar with app engineering, but wouldn't the location access be enough for that?
- greglindahl 6y agoIt's not app engineering, it's a comparison of GPS accuracy (especially indoors) vs a bluetooth beacon. Beacons work great no matter where you go. I'm currently on the 11th floor of a building. GPS accuracy in the vertical dimension is much worse than horizontal. A bluetooth beacon will tell you if I'm in the same room with someone else.
- SlowRobotAhead 6y agoHuh? The contact tracing is 100% Bluetooth. You post a beacon periodically, other people post beacons, everyone is listening for that UUID and records and instances of it. This is how the whole thing works. GPS would be a privacy disaster, if it it did work for this. Random rotates beacons are a privacy issue if you don’t trust your phone mfg, which you should not, but as long as it’s an optional thing is O.K. in the way AppleGoogle are proposing.
