Measured power is determined through a calibration process where you measure the received signal strength and calculate a modified average (throwing out the extreme outliers).

If you have very similar deployment environments, you can do this calibration once and set all of your beacons accordingly. If the environments vary greatly in attenuating characteristics, then you will want to calibrate in place for each unique deployment environment.

Most beacons use non-isotropic antennas, but the team at Radius Networks are working on directional solutions for unique operating environments. Stay tuned!

Measured power is determined by literally measuring the power received at a fixed distance from the beacon.  If you know that the received power is -59 dBm at one meter, then you know that -65 dBm is a little bit more than a meter, and -55 dBm is a little less than a meter.
