Do signal bars mean anything?

The bars (or dots, depending on your phone model) don't relate to actual decibel numbers — instead, they indicate the relative strength of the available signal. The key word here is relative. One bar indicates lower signal strength than two bars. And two bars represent lower signal strength than three bars — and so on.

What does the signal bars mean?
