Why do you need Bluetooth beacon for tracking?

A Bluetooth beacon can be used for indoor tracking.
In some cases, you use the trackers for outdoor (GPS) tracking most of the time. You may wonder, "do I need a beacon too?". Our recommendation is, yes.
The tracker does not know whether it is in a building or not. When it is, it still turns on GPS and searches for satellites, which wastes battery. If there are some beacon inside a building, the tracker knows that it’s in a building and will not turn on GPS. So, Bluetooth beacon can help to save power and extend battery life.
