The IETF AP's go active for a short-time, and then go dark, and when
they come back, they are obviously in a different location
how does the geoloc provider detect that they are in a new locatio?
i assume, but do not know, that google drives by, but not very often.
i have no ideas how others do it. gsm comparison? phone gps? but does
my phone give them those data; i might not like that.
users who geolocate to those AP's quickly shown to be in the "wrong"
place, in that when they get Cell Tower information, it conflicts with
the geolocation hint associated with the AP.
my phone gets the conflict, but does the geoloc provider? does my phone
give them those data; i might not like that.
The service could keep them on a list of AP's where after they go dark
for say, 24 hours, when they come back on-line the system should try
to use location services based on cell tower, GPS, etc., to figure out
where they are on a real-time basis.
i suspect they already do some sort of thing such as this. after all,
it's their business. unfortunately, roaming APs are probably a
negligible percent of their targets; which is why they do not even
answer our email.
