Powering beacons
Modes of operations:
1. Stationary beacons are powered from a clean source of +5V USB
2. Mobile beacon is powered from a clean source of +5V USB from a robot
3. Operations based on internal LiPol 3.7V 1000 mAh cell
-
Typical power consumption in deep sleep mode is 50uA that gives ~2y shelf time with a
regular 1000mAh battery. Beacon can be woken up from deep sleep only by pressing HW
reset button
-
In regular sleep mode, the beacons wake up automatically every 2 seconds for ~20ms to
monitor external calls from modem/router. That brings some additional consumption, but still
leaves several months in sleep mode
-
Active mode work time directly depends on the location update rate. For example:
-
With the standard 1000mAh battery and 16Hz update rate, the expected work time will
be 97h => 8 days (assuming 12h working day)
-
With the extended 4300mAh battery and 1Hz location update rate the expected work
time will be ~5800h or 484 days (assuming 12h working day)
