Detailed explanation-1: -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.
Detailed explanation-2: –80 to-89 dBm, then it’s generally considered good signal (3 to 4 bars).-90 to-99 dBm, then it’s generally considered average signal (2 to 3 bars).-100 to-109 dBm, then it’s generally considered poor signal (1 to 2 bars).-110 to-120 dBm, then it’s generally considered very poor signal (0 to 1 bar).
Detailed explanation-3: -Settings –> About Phone –> Status (or Network) On this screen, view Signal Strength (or Network Type and Strength).
Detailed explanation-4: -We tried it and here’s what happened. On Android, the number of bars displayed on the phone changed when the signal was adjusted under low channel loading. But the number of bars tracks the signal level and appears to be unaffected by channel loading, meaning that the bars represent the true level of signal.
