Does Android device manager location track feature uses gps or wifi or both?
Android uses GPS for location, and if you allow it, also WiFi for better accuracy. Although it stands to reason that the device manager will use whatever you set for the satnav, I don't know this for a fact, and can't find clear information to indicate that.
Thanks. I understand
Tom's Guide attempted the process with both a Google Nexus 10 tablet and a Motorola Droid Razr M phone. Android Device Manager occasionally found the devices with only Wi-Fi active, but not all the time.
Thanks. Please tell, can cell tower triangulation for location ,work without enabling wifi on android?
1.Assisted Global Positioning System (A-GPS)
2.Crowd-Sourced (Google's crowdsourced geolocation database) Wi-Fi
your phone caches information not only regarding the WLAN to which you are currently connected, but also regarding any other WLANs within range of your device. This help Android location services to locate and pinpoint your location faster through triangulation. Android detects that you are connected to your home WLAN and it already has the global positioning coordinates of that precise location, so location services will display your location without going through GPS connection or Wi-Fi triangulation.
3.Cellular network search
well it will start first using Assisted Global Positioning System (A-GPS) then goes to step 2 Crowd-sourced Wi-Fi if wifi not available goes to step 3 Cellular network search if no data plan available so you get error message.
A GPS needs GPS hardware to get location and you dont need data plan or wifi connection. Now applications that have the maps pre-installed do not need the data connection except for updates to the program or the maps so you can use offline maps for navigation, Offline maps, depending the situation needs something like 2GB and more of storage space for storing the maps. aGPS data is cached for a few days degrades and becomes invalid if you change location.
Thanks. Please tell, does the description imply that cell tower location can be used with wifi enabled even though data is enabled through mobile carrier and NOT through the enabled wifi?
The Android Device Manager uses GPS for more accuracy, but can also use cell tower triangulation if there is cell phone service on the device. If there isn't cell phone service or phone connectivity built into the device, then the cell phone triangulation would not work, which means that location by Wi-Fi would either not happen, or would have difficulty in giving a proper location of the device.
hi. Please tell whether location through cell tower work even if wifi is not enabled on android?
There would need to be some kind of internet connection in order to be able to locate the phone since the information needs to be able to be transferred for the location service to use.
With a Wi-Fi internet connection, even without the aid of GPS and the SIM card out or the cell phone service subscription ended, the phone still tries to find service through the nearest cell phone towers. That is how the phone can still be used for emergency phone calls, even without paid services. It is more difficult to always have a proper location of the phone if there isn't a paid subscription service, but emergency agencies can locate the phone during emergency phone calls because of connecting to a cell tower, even without the SIM card or GPS being enabled.
