How is cell signal strength measured?
How cell signal strength is actually measured. The signal your phone receives from a cell tower is measured in decibel-milliwatts (dBm), a unit of electrical power in milliwatts (mW) expressed on a decibel (dB) scale. There are the three things you need to know decibel-milliwatts: 1 milliwatt (1 mW) is equal to 0 decibel-milliwatts (0 dBm).
Why is cell phone signal strength measured in negative numbers?
Since cell phones receive and transmit using much less power than 1 milliwatt (often as low as 0.00000000001 mW or less), cell signal strength is less than 0 dBm and therefore measured in negative numbers.
What do signals mean on a cell phone?
