Exclamation BBmaps now uses cell Tower triangulation - new ?

Please Login to Remove!

Today,
for the first time, I got a location fix within "3000 meters" using BB maps.
Does work without wifi too.

I never saw this before - previously BBmaps either displayed no location, or I had to use GPS.

Is this new to me only ?

does it only do this if the GPS is off? google maps does this and switches to GPS when available. Interesting change though.

I noticed this for the first time day before yesterday. I was in a hotel room, away from the window. I was going to do a local search and just enter the city and state, knowing I wouldn't get a location fix. But it opened showing appoximate loaction with the 3000 m radius. Cool.

I just open BB-maps, and, I see my location.
If GPS reception is possible I get a better fix when activating GPS.
That happend to work after a restart of the device today.

right, works like google maps now - I always missed this option in BB-Maps.

I have two other BB9000, they still work only with GPS, but I am restarting them now - lets see, what happens to these after the reboot.

Yes, just rebooted, and now, those 2 BB9000 will also do cell tower triangulation - nice !

Still wish ATT would let go of TeleNav and stop blocking Maps.

might be just random coincidence, but, compared to google maps, the result is much more accurate - I have to try this out somewhere else.
I think google maps uses just the nearest tower, but If the phone/system (?) really does triangulation a fix within 20meters is AFAIK possible.

I used BB maps on previous units and feel it is much better than most.

I checked a few more things:
The location reported is different depending if on a 3G or 2G connection
The location fix is not dependent on the "data service" of or on status of the "mobile network options"
A location fix without GPS is only possible if the option "location data" option in the GPS options is set to yes.
