[Contiki-developers] Questions about power indicator and transmission range in UDGM: distance loss radio model

[Sara A. <sar...@gm...>]

Hi everyone,

Im trying to understand how Unit Disk Graph Radio Medium UDGM: Distance
Loss radio model is work, and when i search for that i found this:
"Both radio ranges grow with the radio output power indicator, The range
parameters are multiplied with [output power]/ [maximum output power]. For
example, if the transmission range is 100m, the current power indicator is
50, and the maximum output power indicator is 100, then the resulting
transmission range becomes 50m." but i don't understand what is power
indicator and why the max output power is 100? from the datasheet of cc2420
(Im using Tmotesky mote) the max power level is 31 which is 1dbm, 48m so
how can we send to distance grater than 48m?

Thanks
