Hi Carlos,
As always, I agree with anyone who opines a sensibly logical position, so I
agree with you that the "closer" the Apple device is to the access point,
the more accurate the GPS location will be (given to 8 decimal places).
Not only do I have plenty of Apple devices, but I have plenty of routers.
Since we're all on WISP, we have radios galore which repurpose as APs.
So if anyone wanted to query the database every five minutes, for example,
if I carried an iPhone or iPad with me around the house, they could track
me from one side of the house to the other, to the barn, to the stables, to
the pool, to the end of the driveway, etc. The accuracy is that close.
Of course, that's only as good as how frequently the WPS database is
updated when a new GPS location is received that is different from the old.

Actually, it's the location of the access point, which may not even be
inside the home since it can be at the poolhouse or in the stables.
