Again, GPS and cell

So, if I understand this, you have to have a bluetooth device to connect to
your cell, my is N80. Why don't the build in a GPS? Especially in models
like N80. Anyway, what about that WiFi? Don't know what it is, but I heard
it can be used to navigate, but not sure if it can be used with maps or just
to find coordiantions.

Thanks

Hello, again. :-) WiFi is used for wireless networking (computers,
pdas, smartphones, etc.), either private (homes & businesses) or public
(hotspots). Navizon (maybe some others) can use cell towers & WiFi
hotspots as a means of tracking, when GPS is not usable (either because
of the software version or in places like inside buildings, where GPS
just doesn't work). Keep in mind that, in order for these hotspots &
cell towers to be useful in Navizon, they first had to be mapped by GPS
users of Navizon. I'm not sure if any other gps software for the N80
will make use of WiFi or not.

Glad someone brought up GPS!!

I know there's a date, the gov't is requiring all manufacturers to have
GPS built in by this date. Does anyone know what that date is??

Is there any way to see which phones have GPS built in? Any Nokia
phones have it yet?

Been thinking about it lately, my local 911 dispatch center is getting
closed down, 'cuz they can't afford the fancy new equipment that can do
GPS. All 911 calls will now go to the sherriff's office. Just curious
as to how many calls they will get that will be GPS-capable.....

Actually GPS is not going to be mandatory, locating emergency calls yes.
John Navas might have something on the dates on his web. There are many
other location technologies that fulfil E911 requirements, many of those are
network based, saving all the cost from the handset. Some cellular
technologies have difficulties using anything else than GPS though.

GPS is not required. What was required was that, by 1996, all cell
carriers had to be able to take 911 calls (even if the caller
subscribes to another carrier), then by 1998, electronic info on the
closest AMPS tower location could be gotten for any 911 cell call &, by
2001, the location of any cell 911 caller to within 50-300 meters
(approx. 150-900 feet) of any 911 cell call. And the rule indicated
that it didn't matter whether the electronics was in the phone or not,
as long as either the phone or the carrier handling the 911 call could
pass that info to the receiving 911 call center. In areas where there
are more cell towers, radio triangulation is capable of giving more
accurate location info than gps can.
