Google Maps Cell Triangulation on VZW TP2

[Kushiel]

Did anyone else notice that Google Maps cell triangulation works incredibly well on the VZW TP2? I got off the metro, pulled up Google Maps, and it instantly knew where I had come out of the tunnel. About 10 seconds later it got a GPS lock and narrowed down my location even further!

Even better, the whole "Continue to share you location with Latitude" actually seems to work and is updating my location even when I'm not running Google Maps! I don't know how it affects the battery life, but I must say I love my TP2

I have the Sprint TP2. In a totally unscientific study of only one point, my home, the cell triangulation was pretty far off, but it only claimed to be within a 1400 yard radius.
The GPS was very close.

Ok, so the triangulation isn't totally accurate, but it is still a first that you can triangulate using a windows mobile CDMA phone! I think that the GSM radio is still on even when using CDMA and it is using that to figure out where it is. Cool, huh?

It uses tower based ping time to triangulate, while at the same time GPS's your phone. The result is fast locating of the handset. I have Sprint, and so far it works MUCH better than TP1 did.

About 400 feet usually indoors. Tried multiple locations, 400 was the average.

By the way, my GSM radio is turned off, I am on CDMA only.

Is the GSM radio off be default? Where are the settings that let you manipulate which radio's are on or off?

As far as triangulation goes, it has placed me within 500 feet a couple of times, a few thousand meters sometimes, and once it told me that I was in Switzerland (I live in Georgia) ! It updated my google latitude location and a couple of my friends saw it... they were like wtf are you doing is Switzerland??

It works equally well with Bing maps also.

Ok, so I was wondering if it was just an update to Google Maps Mobile, but I just tried the latest version on my wife's Touch Pro and the cell id triangulation doesn't work. It must be something new in the radio drivers of the TP2...

I just got the latest google maps the other day. It's probably a stupid question but how did you know when it was using cell triangulation vs GPS. Also in the old version I was used too on my Titan it would say how many satellites it was locked too, I've yet to see that in this version? I have a terrible feeling I'm missing something simple.

still wondering these two things, bump...
