* PA_LEVEL TXCTRL Output Power[dBm] Current Consumption[mA]
* 31 0xA0FF 0 17.4
* 27 0xA0FB -1 16.5

* 7 0xA0E7 -15 9.9
* 3 0xA0E3 -25 8.5
* Table 9. Output power settings and typical current consumption @ 2.45 GHz
*
* In UDMG.java:
* Calculate ranges: grows with radio output power
*
* moteTransmissionRange =
* TRANSMITTING_RANGE * sender.getCurrentOutputPowerIndicator() / sender.getOutputPowerIndicatorMax()
*
* TRANSMITTING_RANGE is a maximum distance of sending with PowerIndicatorMax()=31
*
* Much linearly!!
