What is dBm power?

dBm (sometimes dBmW or decibel-milliwatts) is a unit of level used to indicate that a power ratio is expressed in decibels (dB) with reference to one milliwatt (mW). … Since it is referenced to the watt, it is an absolute unit, used when measuring absolute power.

What is the good signal strength in dBm?

Signal strengths can range from approximately -30 dBm to -110 dBm. The closer that number is to 0, the stronger the cell signal. In general, anything better than -85 decibels is considered a usable signal.

What does dBm mean for WiFi?

decibelsSome adapters use a scale of 0-60, and others 0-255. Ultimately, the easiest and most consistent way to express signal strength is with dBm, which stands for decibels relative to a milliwatt. Since RSSI is handled differently by most WiFi adapters, it’s usually converted to dBm to make it consistent and human-readable.

Why is dBm used?

dBm is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt. It is used in radio, microwave and fiber optic networks as a convenient measure of absolute power because of its capability to express both very large and very small values in a short form.
