LBS (Location-based service) technology allows to determine the tracker’s location without using standard location services such as GPS, GLONASS, Galileo or Beidou.
LBS locates the position using cellular base stations or Wi-Fi access points.
There are several technologies for positioning calculation:
- Cell of Origin – the device connects to the base station and recognizes the unique identifier of this station. Information about each base station is stored in the public domain, where the location of the base station and its approximate range.
- TOA (Time of Arrival) – in addition to determining the location of the base station to which the device is connected, the time response to the base station is also taken into account, which allows determining the location of the device up to 125 m.
Setting LBS detection radius
LBS detection radius depends on the area where the device are located and the number of base stations or Wi-Fi points. If the device is in a rural area and cannot locate, it is recommended to increase the LBS radius so that remote base stations also contribute to the device’s location.
In a city where the cellular network has densely built base stations, the LBS range needs to be kept small, as nearby base stations will be sufficient for location and accuracy will be high.
