With Location-Based Services (LBS) you may track the location of a person (or vehicle) who is carrying a mobile phone. Mobile phones constantly connect themselves to the nearest GSM or 3G base station, so it's possible to determine the location of the phone by finding the base station to which the phone is connected. How may you use LBS?
- Find out where your field staff are located
- Locate the nearest field staff to handle a problem spot
- Track the movement of your company vehicles (assuming the drivers carry mobile phones)
- Alert the entire office when the boss steps into the office building
There are 2 approaches for getting LBS information:
(1) Getting the location from the mobile operator: After you have subscribed to the mobile operator's LBS service, your enterprise application may retrieve the LBS information from the mobile operator through a programming interface. The location of the mobile phone is typically provided as latitude and longitude coordinates.

The information is returned as a Cell ID, which is a unique number that identifies the base station to which the phone is connected. (See the photos for a sample Cell ID.)
