"dBm" notation represents a measured power level in decibels relative to 1mW. "dBW" notation represents a power level in decibels relative to 1 Watt. "dB" notation is useful for representing gain or attenuation, where the output will always be related to the level of the input signal to a device. The input signal is either amplified or diminished by a certain factor, which is represented in decibels. "dBm" and "dBW" notation is useful for representing a measured transmit signal power level. | Power in mW to dBm (and vice versa) | Enter the Transmit Power in milliWatts (mW) OR in dBm and click the appropriate 'Calculate' button. |
