BLUDistance
Defines levels of distance for beacon advertisements.
These values are used to give a distance estimate for BLUBeacon
objects.
Their calculation is based on the beacon’s transmission power and RSSI values.
Accurate results can only be expected in direct line-of-sight environments with
minimal signal interference.
