These are only going to get more accurate as time goes on, and we begin to use higher and higher frequencies. This works at 2.4 GHz, but would work better at 5 GHz, and would work even better at 6 GHz. The reason for this is that the higher the frequency is, the smaller it is, and therefore the more accurate it can be, and it requires more access point devices, which would make the signal stronger in an area with an access point.
