Ever wondered the difference between dB and dBm? Find out now by watching this video.
Signal Booster Decibel (dB) is Signal Increase/ Decrease versus Decibel Milliwatts (dBm) is Amount of Signal an Amplifier is Capable of Producing or Amount of Signal that Exists at a Particular Location.
dB is a relative figure and is simply an abbreviation for the word decibel. We use dB to describe how much increase or decrease in signal strength we have in our system. Therefore, you will see dB beside amplifiers being sold which means they can help increase signal by that many decibels (For example, 50 dB or 70 dB). Or it may state at a coaxial cable listing that it attenuates (reduces) signal by 1 dB for every 10 feet of cable.
dBm on other hand is an absolute measure of signal strength. It is an abbreviation for decibel milliwatts and is calculated as 10 times the log of the signal strength in milliwatts. It can mean the amount of signal a signal booster can produce or amount of signal at a particular location. Therefore, you will see this term being stated in our cell phone signal booster system design on blueprint of a floor or building indicating available signal strength at a location on the roof or in a room as for example, -60 dBm (strong signal) or -110 dBm (weak signal).
