More experiments with GSM- locate BTS

While working to identify the frequency my android phone uses, here are some important links and apps I came across.


This is an app I used to find out the LAC (Location Area Code) and CID()
https://github.com/SecUpwN/Android-IMSI-Catcher-Detector

The following information and more can be taken form the above app:

  • MCC — a Mobile Country Code. This code identifies the country.
    Sri Lanka- 413
  • MNC - a Mobile Network Code. This code identifies the mobile operator. eg: Dialog-2, CellTel(Etisalat)-3
  • LAC - Location Area Code is a unique number of current location area. A location area is a set of base stations that are grouped together to optimize signalling. eg: 20126, 3003
  • CellID (CID) — is a generally unique number used to identify each Base transceiver station (BTS) or sector of a BTS within a Location area code. eg: 1702739,


This is the link I used to find how to track the BTS with Cell ID and LAC:

Here is an app I used to find the location of the BTS (Base transceiver station).
