GPS info in field test mode on Motorola C343 with Verizona

Posted: 12-08-2003, 05:08 AM
Interesting stuff. I was playing around with my knew phone tonight.

I upgraded from a very old Audiovox CDM-8xxx series phone to the Motorola
C343. I have Verizon cellular.

First I was messing with WAP, SMS/EMS and Ringtones/"get it now" today.
Nothing great. Not impressed with WAP one bit. The polyphonic ringtones
are cool, but it's rather expensive to get new ringtones.

Then I was trying to figure out what use this aGPS stuff was. I understand
the whole emergency call reporting your location, but why does the cell
phone have the ability to set "location" active for 911 only or all the
time? All the GPS calculations are done at the cell towers and reported
back to the 911 operators. The only thing the phone does is relay timing
information to the towers.

I messed with the phone for awhile and grew tired of it.

I previously managed the 300+ cell phones at work and got used to running
around with my V60 in field test mode trying to figure out why AT&T service
was so crappy in our area. For the hell of it, I switched the C343 into
field test mode to see what it was like on Verizon's network.

Well, the usual menus are there. A little extra information is thrown on
there beyond what the v60 had.

One interesting thing though. It had a GPS screen in field test mode. I
let it try to get a lock, but it wouldn't show any values in the fields. It
appears that it has the capability to show; Latitude, Longitude, Altitude,
Bearing, Velocity, Horizontal Velocity, Vertical Velocity and a whole lot
more GPS information. It even has a "SAT" screen that showed GPS satelite
information (all zeros though) and a "Pilot" screen".

I messed around enabling and disabling location to see if I could get GPS to
"lock". I also tried stepping outside and seeing if I could get a GPS
"lock" but couldn't get any information to display on the field test
screens.


Interesting stuff though. I wonder if it will ever show the GPS
information.

I have a motorola v120e that is aGPS enabled. I too can get it to go
to the Field Test Mode screens and have yet to have it show any GPS
info.

I've tried in the DC region, Portland, ME, San Diego, CA, St. Louis,
MO, Virginia Beach, VA, Richmond, VA and still haven't had it work
yet.

I don't know if Verizon doesn't yet have it enabled or what?

Maybe the current software version doesn't support it.

My best guess is that phone actually downloads its location.

It gives a GPS signal summary to the towers, which can then compute
the actual location.

On the 4400 there are debug menus where you can enter server
locations.

GIN and WAP are just based off IP addresses as well, so it
would make sense for GPS to work in some similar fashion.

If you want to try it, go ahead and let us know after you do it.

I have a Samsung A530 and in field test mode it actually shows the
longitude and lattitude. Pretty interesting.

Most likely it depends on if VZW has set it up in your area. Your local 911
PSAP probably gets your GPS info if you call them.
I think this is part of E911 Phase 2. What area are you in?

I have an i730 and it works just fine. The aGPS's 'a' part is to allow it
to obtain it's location fast. The theory or principle is that the phone
will obtain it a locational reference from the cell towers and then 'know'
which staelites to look for. The stats on the Oncore AGPS chip set say that
it can find a location in less than 6 seconds when it is doing AGPS. Now
there is a part that has to happen on the carrier side and that is that they
have install the software to support AGPS. If something like Location
Server isn't running on the carrier's side then you phone works like a
regular non assisted GPS.
I am up in Canada and I know for a fact that Telus is not yet running the A
stuff for the GPS, they have it budgeted but it isn't installed yet. My
phone will take up to more than a minute to return a location intially, once
it has located satelites, usually 3-4, it can hold the fixes rather well. I
have hooked it up to my laptop and driven around the local downtaown area
and the phone had not problems maintaining a locational fix as I drove
around, I was using MapPoint 2002 for the test. I am working on the cabling
to hook it up to my APRS radio as well.
If you want more information on the e911 stuff you might try the Openwave
site and check out Location Server.

BTW here is some stuff from Qualcomm showing how their solution works:
