dBm is short fordecibel (relative to a) milliwatt.In other words, it’s a logarithmical way to convey power level or signal strength. Broadcasting end: dBm as power level (vs. power consumption) When used to convey power level, 0 dBm is defined as 1 mW (milliWatt). That’s how much...

For example 10,000,000,000,000 mW = 1013 mW = 130 dBm As well, it makes RF budget calculations simpler than with linear values. How to convert from Watt to dBm To find the dBm equivalent of 1 W, first convert it to milliwatt. In this case, it is 1000. In general the value in...
