What is a "Cell Phone Signal Strength Comparison"? The Most Authoritative Explanation.

How strong is a cell phone signal?

Cell phone signal strength is measured in decibels (dBm). Signal strengths can range from approximately -30 dBm to -110 dBm. The closer that number is to 0, the stronger the cell signal.

What is considered a good cell signal?

What’s considered “good” cell signal? 4G and 5G cellular signal strength are measured using RSRP (Reference Signal Received Power). Excellent signal strength on the RSRP scale is anything stronger than about −85 dBm; poor signal strength is anything less than −115 dBm:

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 about decibel-milliwatts: 1 milliwatt (1 mW) is equal to 0 decibel-milliwatts (0 dBm).

Why is cellular signal strength important in a commercial building?

Cell phones have become foundational for both individuals and businesses when it comes to communication, so it’s more important than ever to have good signal strength in your commercial building. A strong cellular signal ensures seamless conversations with fewer dropped calls and faster, more reliable transmissions when sending or receiving data.
