Hi guys,
Have you ever heard about the location search function on certain carriers?
For example, X wants to know where Y is, both doesn't have GPS or internet function. X sends an sms to the carrier to locate a number.
Y then receives an sms for permission to allow X to know his/her location. When approved, X receives the location of Y.
I was wondering if this can be done on our phones to know our own location?
Benefits:
-saves battery (not using data or GPS)
-saves time (don't have to search for satellites)
I found out on how to calculate our longitude and latitude from here:
http://stackoverflow.com/questions/...triangulate-gsm-cell-towers-to-get-a-location
Maybe when we get our longitude and latitude, we can trick our phone by thinking it is a GPS data, allowing navigation apps like Google Maps to point our location.
Any devs wanna work on this project?
Lol just turn off your gps and use mobile internet in gmap. You can see tower based location in map

With what I suggested, you don't need internet
All you need is a normal GSM connection.

without internet I think its not possible because gmap need internet connection to load the area. Latest gmap has the Offline Map feature where we can preload an area. When we visit that area,we can get turn by turn navigation without internet

Okay. Assume we have an offline map like you mentioned above.
What do you use to determine your location for that turn by turn navigation?
Gmaps uses GPS or internet to determine our location.
But our carriers determine our location from the strength of tower signals around you.
Open the link on the 1st post for a detailed explanation on how it works.

It doesn't use internet because it only uses the coordinate of nearby towers and their signal strength to calculate our location.
Hope any devs can make an app to read tower information, calculate coordinates and point it on a map, tricking it into believing it comes from GPS or data connection.

Sygic does the trick

In certain locations, gmaps support offline maps too.

Thanks, I'm gonna try it.
Doesn't work with Sygic. It still needs GPS.
Is there any way of making your phone think that data from GSM triangulation is coming from GPS?

Is there some application that can monitor internet usage by application? I know 3G Watchdog does the job, but it only shows the global consumption and I want to see which apps are using my internet because sometimes I can see my internet being used but I don't know which app is using it.
Also can someone tell me how I can deactivate it and turn it on until I need it.
Thanks!!
Have a look at Call meter NG...

Count what about GPS exactly?
Sent from my X10a using Tapatalk
GPS is never counted as data usage, it uses signal from GPS satellites, not the internet connection. However, if you are using Google Maps, the internet connection is used to download the maps.
3GW has not yet the capability of counting usage per application, but a "pro" version will in the near future, only for phones under Android 2.2+ because it's not technically feasible AFAIK with older versions of the OS.
Hey guys,
I really need per app counter especially now for my X10.
I have only a 200mb plan, but I don't ever do anything else on the internet except use Google Voice app to text(since I tend to text a bunch).
Anyways, first month that I had the phone my traffic got up to about 120mb, but that was because I browsed web etc (you know.. got a new toy and started to play with it type of thing), but after this month I installed counter and monitor it from AT&T's website too, and half-way through the month traffic got up to 140mb!
Now I have disabled background data once I noticed that, now I have enabled it but uninstalled Google Voice app, and gonna have to go without it for few days (which isn't that great) and see if it's it that's causing the problem.
The thing is that I need the app one way or the other, and second is that I want to know for sure what EXACTLY is using my traffic.
Any advice is welcome.

Hi,
I'm just wondering why my GPS doesn't work without internet connection. It just can't connect to any sattelite. I'm currently using PFGPS v2.0 FIX for my country (Poland) and I don't see any changes. What is wrong?
It requires Internet to load the maps
Can I load maps now to use GPS without internet connection if I'm not in wifi area?

so you have wifi that means you are connected to the internet!!!
for GPS it can only find your position but can't display your location on a map without an internet connection so GPS needs one.
I will wait for answer from another person. Thank you.
There is an application on the market(related to sports/tracking) that allows you to download a portion of a map and then you can use your GPS offline(no data connection). When I get home I will look for it(I have it on my tablet).
Correct me if I am wrong but Brajano95 means that is it possible to load the maps on his wifi connection and keep then saved when he is out and about to allow the gps to connect. You used to be able to do this in the google labs section on google maps but they've since taken it away unless you look for an older version. Otherwise have a look for third party map app on the android market which allows downloading of map data to the phone

Thats exactly what I'm talking about! Now I'm downloading Sygic Aura (about 550 mb) and will test it later.
Because GPS and Maps on CM7 suck balls at best. Maps is using your I.P. for the GPS coordinates when on WIFI, without it Maps is counting on a reliable signal from your GPS; and that's just not going to happen with CM7.

I know a fair bit about the GPS module in the Ace so i will comment. I think someone has already told you that it is possible to operate the Ace with preloaded maps. Likewise, i thought that the OP's choice of Sygic Navigation is a fair one.
Back to the original question in the title. GPS can operate with or without internet be it wifi or data e.g. 3G/2G. The difference is how fast you can obtain a GPS lock. Without using any positioning help from data connectivity, you are looking at a lock time of possibly 15 minutes thereabout.
There are 4 modes of operation possible for the GPS module in the Ace which is actually Qualcomm's GpsONE.
1.) Standalone (Slowest using positioning information in cache and smart polling)
2.) MS-Based (Sends data to nearby cell tower(s) and makes use of GPS transceivers in the cell tower(s)
3.) MS-Assisted (Similar to MS-Based BUT data connectivity is broken when GPS transceiver is online. I don't quite like that!)
4.) MS-Based/Hybrid (You need to have superb data connectivity probably cell tower signal strength should be in the -50dBm region. Not very useful in real life usage)
i have had my own thread for fixing GPS, so read up if you want to know more here.
http://forum.xda-developers.com/showthread.php?t=1320626
first you need the maps to use it offline, and the correct gps.conf for your location http://forum.xda-developers.com/showthread.php?t=1284506, then you can use it without internet
Mapdroyd is a great app that allows you to download maps for offline use. Unfortunately there isn't offline navigation though..
Hi,
I've solved my problem, just install Sygic! Thanks for helping guys
btw u dont need too install anything.. go to google labs inside maps and add map cache.. now long press a location on map.. click the arrow on the address and u ll see an option to cache that area.. the steps may not be accurate as i tried it a long time back and dont have my phone with me but its possible and what u have to do will be more or less the same...
Is gps a real gps or actually a-gps? Seems all tablet and phone want to confuse people this.
The GPS on Galaxy Player is a real GPS and it is pretty accurate. However, you need to find an app that DO NOT use data connection. May apps require you to have a data connection and it will give you an impression that the GPS is not working.
People have been talking about this in this thread.

Technically it is not a GPS... It is an aided GPS through the use of cell phone towers, so yes A GPS. It is very accurate though. Use Navfree if you want the use of offline maps. No internet connection is required once you install the maps. Hope this helps.
Yes it has Both..
AGPS when you have WiFi connection can be achieved.. much faster fix.
Once you had already acquired this and had initial fix, it's much faster to have a GPS fix for days..
use app like "gps status" free from market.
Note: It uses Satellites so its more easier to have a fix when you're outside and have a clear sky.
Two apps that come to mind for offline map is Map Doyd and Nav Droyd.
In map droyd the maps are free but Navdroyd will cost you a small onetime fee.

It can receive assistance from the network, but unlike many AGPS solutions, it does fairly well when operating standalone. It CAN lock fairly quickly when standalone, the only other devices I have that lock as well standalone are my Tab 10.1 and my GS2. (Original GalaxyS devices and the Infuse have GPS receivers that perform horribly without assistance.)

No phone function in YP-G70, so not A-GPS obviously. Don't you need data connection in Navfree to enter address even you have offline map?

Hi, I have very inaccurate location based on the cell tower triangulation (in building), it shows me my location to be almost 100 m away outside of the building. (my friends with G2 and S3 has got correct location in the building , when they are on the same place as me).
Please do you have any tip, how to fix it? Or there is nothing I can do with it? (only to buy a new mobile)

cell tower location is always inaccurate. your friends were probably using wifi location. in settings, these two are together called battery saving location. just turn on your wifi and you'll have the right location displayed, you don't need to be connected to the wifi network, you just need any kind of internet connection

Well actually we have both switched wifi off (and we turned off the GPS in location menu). and we have the same net provider. I have even downloaded antennas program, and put it on the both mobiles, they are at the same place and both shows a different location.

lol if you turn gps off, your phone just shows the last location it remembers.. also, it is possible that one of you has turned an option on, which enables for the phone to look up wifi location even when wifi is turned off

yep, that would be the reason - their GPS can fix the location even in the building, so the last location is from the building... Thank you for your tips, I will not any more waste your time... Another lesson is learned, next time, when I buy a mobile, I will run a GPS test to be able to return it within 14 days of protection period...
my final year project proposal is " indoor positioning system based on smart phone", and need to make a software for it ..how can i solve it ..any idea :laugh:
I suppose the first place to start would be seeing if you could use Wi-Fi or Bluetooth. You may be able to write a program that would tell you where the phone is in relation to the Wi-Fi router or a stationary Bluetooth device.
