* The received signal strength at Sydney was measured on a spectrum analyser where
0dbm is equal to 1 milliwatt into 50 ohms.
-3dBm is half a milliwatt
-6dBm is 1/4 of a milliwatt
-9dBm is 1/8 of a milliwatt.
For every 3dB below 0dBm, a signal loses half its strength.
dBm = log( mW ) * 10 or mW = 10 ^ (dBm/10)
