but it do everything in Europe, MENA, ,,, ,,,,,

the only problem with it is the battery

The only service I don't have access to (haven't really tried either) is the old Cingular Video app.]]>Feb 9th 2008 3:19PMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/Feb 9th 2008 9:11AMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/
It stands to reason that if my TomTom knows the stretch of road I'm on, the speed of that road, and the speed that I and any other TomTom user on this road are actually travelling at, that it could judge for itself whether or not traffic is present, and send a signal to other TomTom users devices adjusting their route to avoid the particular stretch of road that I'm apparently stuck in.

Social sat-nav, if you will; and the market saturation necessary to achieve this is already growing daily.]]>Feb 9th 2008 9:47AMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/Feb 9th 2008 9:55AMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/
If the satelite can see that I'm doing a 5 MPH average on a road where I should be capable of doing a 70 MPH average, and so are a multitude of other devices around me on this same road, it should be able to do something with that observation for other TomTom users destined to travel along this same stretch of tarmac.

Does that make it any clearer?]]>Feb 9th 2008 10:42AMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/Feb 9th 2008 2:13PMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/
All this information gets sent to my device, and could be averaged against the very same data being sent to other devices in the area to confirm the extremity (and on motorways the precise junction) of a problem, to then push a suitable re-route.

I can't possibly make it any simpler to explain short of attempting to doodle in ASCII.]]>Feb 9th 2008 3:01PMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/
Let me give you a quick primer on GPS: all a GPS satellite is is an atomic clock in geostationary orbit. All it does is broadcast the exact time according to its clock over and over and over. (Actually it sends some other stuff about satellite positions as well, but that's the essence of it.) It does not know what's being done with that. It does not know who's receiving it. It does not know that humans are using the ephemeris data to triangulate their positions down on Earth.

The way GPS works is that your GPS device compares the time code it receives from the satellite against its own internal clock and uses the difference between the two, along with a handy constant you may have heard of, to determine how far away the satellite is. Put three satellites together and you have a two-dimensional coordinate. Take change in position over time and you have speed. You may have learned this in high school physics.

Your GPS device is what tells you how fast you're going and where you are. GPS satellites have no ken of positions or speeds. They're just clocks.]]>Feb 9th 2008 5:27PMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/

That project is already 5 years old, so I have no idea why UC Berkeley think they are onto something.

By gathering information directly off the network, it's possible to track every single mobile phone on a specific route, and not just a couple of users that happen to be participating in the service.]]>Feb 9th 2008 9:51AMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/Feb 9th 2008 9:57AMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/Feb 9th 2008 10:11AMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/Feb 9th 2008 11:19AMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/Feb 9th 2008 1:58PMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/Feb 10th 2008 1:27PMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/Feb 10th 2008 2:35AMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/Feb 10th 2008 12:20AMhttp://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/http://www.engadget.com/2008/02/09/nokia-trial-turns-n95s-into-traffic-sensing-tools/
