I think you might underestimate how big is the error in the normal (wifi) location sensing (e.g. see here[1]). Bluetooth beacons add a much more localized spot, so much less likely to pop up the wrong place on your device, which is very important for this to be any real use.

- Macuyiko 11y agoYup, that might be... though theoretically it might be possible to calibrate this in a more fine tuned manner if you know/have access to the WiFi hot spot/box beforehand.
- NathanKP 11y agoExactly. GPS could probably work well enough in suburbs and other areas with fairly wide spaced buildings, but in a urban environment there could easily be ten or more businesses within the margin of error for GPS location detection.
