Hello, Milton ,
LBS stands for Location-based service designed for positioning by cellular towers. In other words, a unit is located by coordinates of the closest GSM base station. LBS accuracy is quite rough, but it is a good way out when GPS positioning data are unavailable.
If you want to use it, first, make sure your tracker is able to send LBS data. For data transmission, GSM module is to be registered at a network provider cell base station which transmits its ID and a number of parameters. Therefore, to locate a unit by LBS the device should send at least 4 parameters: mcc, mnc, lac, cell ID.
You can check the data that comes from the device in the Toolbox.
If such data comes from the device, you can use the LBS position button on the unit card in Ruhavik.
