7.13 Powering beacons

Modes of operations

1. Stationary beacons powered from a clean source of +5V USB

2. Mobile beacon 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, which provides ~2 years

of shelf time with a regular 1000mAh battery. The 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 the modem/router. That causes some

additional consumption, but it can still be left for several months in sleep mode

- Active mode work time directly depends on the location update rate. For example:

o With the standard 1000mAh battery and 16Hz update rate, the

expected work time will be 97h => 8 days (assuming a 12-hour

working day).

With the extended 4300mAh battery and 1Hz location update rate, the expected work time

will be ~5800h or 484 days (assuming a 12-hour working day)
