What is dBm and How Does it Relate to Cell Signal?
https://www.signalboosters.com/blog/what-is-dbm/
dBm stands for decibels per milliwatt. While dB is the expression of a gain and is dimensionless, dBm meaning is a concrete measurement of the power level. It is used to define signal strength in wire and cables at radio and audio frequencies. dBm is measured is very small values. The formula for calculating dBm measurement is 10 x log (signal ...
Mixing: Signal level - Lenard Audio

0dBm refers to 1 milli Watt across 600 Ohms which co-insides with being 775 mV. This reference applied to valve technology pre 1960 and no longer applies. This dBm and dBu as 0.775V is confusing and should have been deleted many years ago. 0 VU should be referenced to 1V as dBV. Professional audio O VU +4dBm (1.23 V)

When digital audio emerged, it needed its own dB system, which brought the need to choose a reference. But there was a problem: Digital audio can be 8 bits (sample values from 0 to 255) or 16 bit (0..65535) or 24 bit (0..16777216). It seems like the common thing in all these bit depths is the zero, but we can't use it as a reference as we'll get:
The dB in Communications - Colby College
https://www.colby.edu/chemistry/CH332/laboratory/dB.pdf
In standard audio systems 0dBm is defined as .001 watt measured with respect to a load termination of 600 ohms. A 600 ohm balanced audio line is the standard for professional audio and telecommunications. 0 dBm is defined as 1 mW measured with respect to a 600 ohm termination The voltage measured across a 600 ohm load for an 0dBm level is .775 ...

The nominal telecom signal level was defined as 0dBm — the 'm' signifies a reference of 1mW in 600Ω. When the broadcasting and audio industries moved away from matching impedances and towards bridging inputs, the '1mW in 600Ω' reference became meaningless, but the same nominal signal amplitude was retained.
