Every 6 dB will approximately double the coverage distance from antenna (or cell tower).For example, -67 dB is twice the power of -70 dB. This means that every 3 dB increase doubles the power. Cellular signal strength is measured in decibels (dB), and typically range from -50 dB to -110 dB.However, if your phone is reading at -100 and you get the same booster, you will get a very strong signal (besides, the phone will never show you anything above a -50 on a phone). For example: If you purchase a cell phone signal booster that claims that it can boost your phones decibels up to 50 points, but your signal strength is reading at -157, your signal will still be pretty weak. If you think of the decibels on the phone as the detailed information to gain the best signal, then you will understand how the bars are really superfluous to understanding how your phone works. What does negative number cell signal mean?Ī negative number as in cellular signal signifies the strength of the signal in decibels.

In addition, it does not update in realtime.
Sure, you can look at the bars and get an indicator as to how strong or weak your input and output will be, but this visual indicator is not very specific and is prone to change with the slightest shifts of the phones position. If you want to perform a diagnostic check for poor cell phone reception or if you want to know the strength of your cell phone's signal accurately, then you must set phone for dB reading because you need to be able to check the DB (decibel) strength of the signal dBm rating. A how-to guide for checking signal strength more accurately on Apple IOS and Android cell phones.
