What is a "How To Measure Cell Signal Strength"? The Most Authoritative Explanation.
How is cell phone signal strength measured?
Signal strength for cellphones is calculated using dBm (or decibel milliwatts) as its standard unit of measure. On a signal strength meter, dBm is typically expressed as a negative number—such as -88. The closer to zero the reading is, the stronger the cell phone signal.How strong is your cell signal?
See the cell signal strength chart below for a great comparison: The typical range of measure for cell signal strength is between -110 dBm and -30 dBm. Being a logarithmic unit of measure, each 3-dB increase is actually doubling the power. So, a cell signal that measures -76 dBm is twice as powerful as a cell signal that comes in at -79 dBm.Where can I Find my received signal strength?
If you have an Android smartphone, you can find your received signal strength in the phone’s settings under Signal Strength . Exactly how to get this varies between phone models, but it’s usually somewhere in Settings > About Phone or Settings > System > About Phone.What unit is used to measure signal strength?
Measure Signal Strength in Numbers (dBm) Signal strength received from a cell tower is measured in decibel-milliwatts and represented by the unit dBm, which is a unit of electrical power in decibels (dB) in reference to 1 milliwatt (mW). dBm is a more advanced, quantifiable measurement of signal strength.
