Quick Question:
Is it possible to use any of these new 'GPS-capable' cell phones (such as the Motorola T720) as a GPS device for use with a Pocket PC?
I'm not sure if they have full fledged GPS capabilities, or if they can only be used for the 'emergency 911' location services that they are advertised for by the cell phone companies.
You guys are the pros...so if you have any thoughts please share them.
Thanks!

You know that's a good question (I"ll create a separate thread for it in the GPS receiver section!). I haven't seen it discussed anywhere really!
I'd be inclined to say no because something tells me they're not set up to do that in the first place and GPS manufacturers would probably want to sell you another reciever for your PocketPC...
Nevertheless it's worht looking into!

Found this here. It seems like this technologyu is picking up speed !

"QUALCOMM Announces Advanced GPS Radio Receiver for UMTS and GSM/GPRS Systems
RGR6200 Chip and System Software Enable Highly Integrated GPS Solution with Unmatched Acquisition Speed, Accuracy and Sensitivity
SAN DIEGO -- October 3, 2002 -- QUALCOMM Incorporated (Nasdaq: QCOM), pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, today announced the highly integrated RGR6200™ Global Positioning System (GPS) radio receiver. The RGR6200 solution is designed to interface with QUALCOMM’s MGP6200™ multimode GPS processor and MSM6200™ Mobile Station Modem (MSM™) chipsets. As a complete solution, these chips provide best-in-class GPS performance for UMTS and GSM/GPRS systems, enabling simultaneous GPS operation with UMTS/GSM/GPRS radio operation.
"The RGR6200 radio receiver offers unrivaled performance for a cost-effective solution," said Don Schrock, president of QUALCOMM CDMA Technologies. "QUALCOMM is dedicated to bringing the most advanced solutions for position location to the wireless marketplace, and the RGR6200 solution offers the best UMTS GPS sensitivity and selectivity in the industry."
The RGR6200 solution incorporates QUALCOMM’s radioOne™ Zero Intermediate Frequency (ZIF) architecture, which eliminates the need for IF components, including large IF SAW filters and additional IF circuitry. CDMA chips using radioOne technology require less printed circuit board area than previous generation chips, which reduces bill-of-material costs for wireless handsets.
Offered in a 5mm x 5mm 32-pin Quad Flat No-Lead (QFN) package, the highly integrated RGR6200 solution includes on-chip:
Low-Noise Amplifier (LNA)
Additional high-linearity pre-LNA
Mixer
Voltage Control Oscillator (VCO)
Channel select filtering
Phase-Locked Loop (PLL) circuit
QUALCOMM’s Serial Bus Interface (SBI)
The MGP6200 solution, to which the RGR6200 chip interfaces, is a companion chip for the Company’s MSM6200 chipset. The MGP6200 chip uses the proven Assisted GPS (AGPS) fast-convolution hardware core and software algorithms from SnapTrack®, Inc., a wholly owned subsidiary of QUALCOMM, to provide significantly enhanced GPS signal sensitivity, fast start times, multipath mitigation and power optimization, while minimizing positioning data traffic on wireless networks.
The MSM6200 chipset is QUALCOMM’s second-generation UMTS solution and supports data rates of up to 384 kbps. The MSM6200 solution interfaces with QUALCOMM’s wireless Launchpad™ suite of applications and software, encompassing advanced multimedia, connectivity, position location, user interface and removable storage capabilities. Selected components of the Launchpad suite are integrated into all of QUALCOMM’s MSM chipsets based on the market for which each chip is designed. The MSM6200 chipset and system software also support QUALCOMM’s Binary Runtime Environment for Wireless™ (BREW™) Application Programming Interface (API). With the BREWapi™ routines, protocols and tools, handset manufacturers and developers can develop both embedded and downloadable wireless applications, and BREW-based products more quickly and easily.
The MSM6200 chip sampled in June 2002. The full MSM6200 solution, including radioOne ZIF RF technology, is currently available. An MGP6200 chipset solution will be available inside a small, commercial-quality test handset from QUALCOMM in the fourth quarter of calendar 2002 to enable commercial trials by wireless operators. Engineering samples of the RGR6200 solution are expected during the first quarter of calendar 2003.
QUALCOMM Incorporated (www.qualcomm.com) is a leader in developing and delivering innovative digital wireless communications products and services based on the Company’s CDMA digital technology. Headquartered in San Diego, Calif., QUALCOMM is included in the S&P 500 Index and traded on The Nasdaq Stock Market® under the ticker symbol QCOM."

Actually I did a search on the Motorola T720 and there's no mention of a GPS being built in. Are you maybe confusing it with GPRS whcih is a data transfer protocol ?

Ok, third time is a charm. I'm tired of retyping this post and letting it get lost in the wind 
First of all, congrats on your forums, GpsPassion (or should I say Yellow1?)! Now I have two sets of forums to monitor (yours and pocketpcpassion)! Lets see how well I end up doing.
Back to topic. I believe Jon McNash is referring to the location service that for instance is used by AT&T's mMode:
http://www.attws.com/mmode/features/findit/index.jhtml
It's OK, but not great. Accuracy is so so, and you cannot do real time tracking, for instance. (That I know of). I first remember hearing about this about 4 years ago when some researchers in Sweden (could it be Ericsson?) were working on it. I believe the primary goal was the emercency/911 features it would provide, and a secondary commercial interest where for instance you get an SMS "ad" from a restaurant as you approach it.
I've tried it with my T68i, and it manages to find my position with a few blocks accuracy.
Just don't think that it can replace a GPS. At least not yet. Perhaps in a few years... 
Just my two cents. |

Thanks for the info.
Sorry you had to retype, what was the problem?
Yes in the meantime I found that a lot of the excitement had been generated by people confusing GPRS and...GPS!
Tried your link, but that I can't see any decent explanation on what mMode is...does it locate your position like you what you do with your T68i and then tell you what the closes restaurants are?
Do you have to pay to get your position via the T68i?
cheers

Was my first time logging in... cookies didn't take properly. Mostly (l)user error.

Ditto here. It's amazine what difference one character can make. ;)

mMode is in essence what AT&T is calling it's GSM/GPRS package. It includes everything from SMS text messaging to the advanced "find friends" feature.
The latter, if set up, can actually give you alerts if your friends are near. To prevent Orwellian monitoring by friends, parents, you get alerts when someone "looks you up", and you have to explicitly permit people to be able to alert on you, etc. I've never tried it, since I don't know anyone locally with AT&T GSM (mMode) service. (They just started up with it here in the DC area in August.)
Do you have to pay to get your position via the T68i?
I don't think you have to pay for the actual location, but you may have to pay for some of the services that use it, just like you would have to pay to use Vindigo and similar services.

| I am very interested into tapping into the GPS capabilities of my phone. I have the motorolla T720c from verizon wireless. It does have a built in aGPS (assisted GPS for anyone not familiar). There is an option in the phone to turn the location service (what the phone calls aGPS) for E-911 only, or for always on. The really interesting part is that there is GPS software on the phone (requires some digging and some tech codes to get to), but I've been unable to get a reading I get all zeros and an unable to connect message (NO CONN. w/ PDE) which I assume to be the satellite connection. If anyone is more familiar with this sort of thing or wants to take a shot at it please let me know and I can tell you how to get into the GPS software on the phone. Someone supposedly got the GPS to work on their phone and got an accurate reading. This message is getting long, so I'll end it here. |

I also have a T720c. I'd like to know how to get to the GPS software. Also can you tell me where you heard this, I.E. a forum or something?
Can you say Mapopolis for Moto!

Yeah...to get into the gps of the phone you have to put the phone in test mode. To do this hit menu then quickly key in 00**83786633*( which spells out 00**testmode*) (you may have to try a few times if you until you do it fast enough). This will bring you back to the original screen if you did it correctly (you will be in test mode). What this does is put the phone in test mode. To get to where the gps information is hit menu then the left '.' key. The first page is the tower info. If you go through the pages (the '.' keys are 'prev' and 'back', the 'next' is a little misaligned, you'll see what I mean), you will get to a page that says GPS Session in progress please wait...after a bit it will give you your coordinates (mine says 'no conn w/pde' and puts 0's for the coordinates, but I've talked to people who say they've gotten it to give them coordinates, I think it depends on if the towers are set up for aGPS or not). That's about as far as I can get with the GPS stuff. To get back to your normal screen hit menu and left '.' again. Make sure to disable testmode after doing so to use your phone again. You disable testmode the same way you enable it. (If you get a black screen or a black screen with white and fts on top don't panic, your phone isn't messed up...just hit menu then left '.'). Let me know how you make out. Hope I didn't confuse you too much.

A couple things I forgot.
This works exactly the same way on my fiance's v120e from Verizon.
If the GPS thing says 'loc priv on' or something like that you have to go into the normal menu and enable GPS for all instead of 911 only. |

Thanks for the info on how to enter test mode. I successfully got into test mode but get the same thing you did....all zeros, etc.
I called Verizon to ask if the towers in my area had been enabled for gps yet and they told me that if I have a "cross hairs within a circle" symbol at the top of the display, that the cell tower(s) I am receiving are gps enabled. I have that symbol but still can't get coordinates or other info. The tech support folks at Verizon couldn't tell me what elso to try so I'm stuck at this point. They gave me a number for Motorola Tier Support but it doesn't work. Just a recording that says the number is no longer in service. Does anyone know the tech support number for Motorola Tier Support? I'm wondering if there are other settings on the phone that have to be changed to display the gps info.

 VZW has not turned up the gps network in all areas yet. Last count was 455 PSAPs in 19 States, have Phase II E911 service. If you are interested you can goto the FCC website http://www.fcc.gov/911/enhanced/reports/phase2-waiver.html and see the Phase II waiver documention. Once the Phase II service is available you can use your T720 as a GPS device. The T720 displays long,lat, and altitude. By the way (NO CONN. w/ PDE) is: No connection with the Positioning Determining Entity. The PDE is a server that funnels the data info between your phone, your service provider, and the PSAP. (Public Safety Answering Point or E911 operator) Hope this helps.

I didn't see a complete answer to the original question, but I'll pose it a different way.....
Are the majority of the GPS capable phones getting their location data directly from the GPS satellite signal, or are the cell towers simply getting assistance from GPS signals and calculating the location for the phone?
I guess what I want to know is will the phone function as a standalone GPS receiver, even if I can't get a cell signal? So if I'm on my boat about 50 miles offshore where no cell tower can reach me, will I still receive a GPS location?
I was thinking of a Kyocera 7135 phone to replace my PDA, current cell phone, and Garmin 12CX Handheld GPS. Sure would be nice to trade in three things for one.
Any advice or opinions would be greatly appreciated.
Thanks,
Michael |
