Any idea how to get Cellular location data when using 3G modem? It is more a generic question, but if hardware matters, lets say we are using Huawei E3131 USB modem in HiLink mode and Ubuntu 12.04 or later.

Thanks

  • Please, who ever is is trying to answer, do not confuse A-GPS with actual GPS sensor data. A-GPS location is based on the cellular network, not actual GPS satellite communication.

  • OK, probably I mistaken using A-GPS as a term. My question is how do we get the triangulated location from the cellular network?

I think there is some confusion here. The modem you describe does not have a GPS reciever built in. The only thing you could try is to do a triangulation with cell phone towers to estimate you position. A GPS lock is not possible.

    That is why I am talking about A-GPS, not GPS! A-GPS data is based on the cellular network, not on actual GPS sensor.

  • Sorry, but you are wrong. A-GPS is a network assisted GPS. This means that your GPS has a faster startup time, but you still need the GPS. en.wikipedia.org/wiki/Assisted_GPS

  • OK, lets say it is. I`m wrong in the terms I am using. My question is how do we get the triangulated location from the cellular network?

From the cellular module, the network cell information can be retrieved. IF module is 3gpp supported network cell info can be retrieved by AT command "AT+CGED".

Required cell info required to find out the cell location is: MCC,MNC,Cell Id,Location Area Code.

Using the third party API you can get the location of the cell connected. As it is done in these sites https://cellidfinder.com/ http://www.cell2gps.com/
