How much gain is 100dB?
In simple terms, a booster will boost the cellular signal by a certain number of decibels. A 10dB change corresponds to a change in power by a factor of 10 – so 100dB is 1000X (10X10X10) more powerful than 70dB.
How much gain is 40 dB?
When talking about power, a 3dB represents a ratio of two to one or a doubling of power. A 40dB power gain would be 10,000 times the power.
What is dBA and dBc?
Decibel measurements made with the A-weighting scale are denoted as dBA; those with the C-weighting scale as dBC. There are other weighting scales to account for the range between A-weighting (soft) and C-weighting (loud), but they are not used much anymore.
How much gain is 10dB?
10 dB gain/loss corresponds to a ten-fold increase/decrease in signal level. A 20 dB gain/loss corresponds to a hundred-fold increase/decrease in signal level. In other words, a device (like a cable) that has 20 dB loss through it will lose 99% of its signal by the time it gets to the other side.
