DBM (Decibel Milliwatts)

The decibel is a relative scale used to represent the power and voltage strengths of electronic equipment, like signal boosters or the wires and cables that connect to radio and audio frequencies. Because the decimal is logarithmic and therefore a dimensionless unit, we apply the unit dBM, or decibel milliwatts, as an absolute point of reference.


This means that power- in our case, signal strength- is measured in reference to one milliwatt, and can be calculated as ten times the log of the signal strength is milliwatts. The dB simply quantifies the ratio between two values, and those values are measured by dBM. So once the dBM has been established, only then can you measure any change in decibels (dB). Its capacity to express values both large and small in short form makes dBM in the measurement choice in radio, microwave, and fiber optic networks. In the world of cellular signal boosters, dBM measurements represent the strength of a signal at any given location, as well as the amount of power an antenna is capable of amplifying.


Good Signal Strength of dBM

Typically, a strong outside signal would clock in somewhere around 50-70 dBM,while anything below 100 dBM would be considered weak (-110 means no signal at all). The use of an indoor antenna could boost that outside dBM signal exponentially – for example, an indoor antenna that is radiating- 20 dBM can effectively cover about 3000 square feet, according to the logarithm, the signal strength doubles with every third decibel, meaning that a dBm signal of something like- 70 is actually twice the power of -73 dBM. The numbers may not like it look like a great chance has occurred, but in reality, the decibels have grown exponentially.

How to Take dBM Measurement on Phone

When the strength of your cell phone signal matters most, skip the bars on your screen and opt for the master precision of dBM signal strength measurements. Whether its choosing the strength of your signal booster or figuring out where to install it for optimal efficiency, apps like Network Cell Info make it easy to monitor and measure the dBM in real-time, everywhere you go. Android phones offer a decibel reading function in their settings, while most iPhones can access decibel information by turning on “test mode”. Simply “call” the number *3001#12345#* from the keypad, and the dBM reading will either appear in the top left corner or can be found by sliding down from the top edge.
