dBm Definition: dBm is the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). The formula bellow can be translated as: "the power P(dBm) in dBm is equal to 10 times the base 10 logarithm of the power P(mW) in milliwatts (mW) divided by 1 milliwa...

The Bluetooth power is classified as Class 1, 2, and 3. Class Maximum Power Operating Range Class 1 100mW (20dBm) 100 meters Class 2 2.5mW (4dBm) 10 meters Class 3 1mW (0dBm) 1 meter Most devices and smart phones are operating within the Class 2 power range. ...
the difference between -60 dBm and 60 dBm is very significant. dBm is a unit of power relative to 1 milliwatt (mW), expressed in decibels (dB). A decibel is a logarithmic unit used to describe the ratio of two power values. When the signal strength is -60 dBm, ...

Accordingto Speedcheck.org, “the difference between the two is that RSSI is a relative index while dBm is considered an absolute number representing power levels in mW. Hence, the closer to 0 dBm, the better the signal is.” Rememberthat “a 1 mW signal has a level of 0 dBm. Signals...

To put any physical quantity into a decibel-like unit, you need to first divide by some reference quantity. For example, the "decibel" unit for power is "dBm", which is the ratio of the power in question over 1 mW, expressed in dB: [dBm] = 10 log_10 (Power / (1 mW))...
