What is a "Signal Bar"? The Most Authoritative Explanation.
What are the signal bars on my phone?
These represent your phone manufacturer’s impression of your current cellular signal strength. Unfortunately, the signal bars are arbitrary and do not correlate in any way to your actual signal. In other words, there is no standard measurement unit for the bars. 4 out of 5 bars on one phone could show up as 2 out of 4 on another.What do the bars in signal indicator mean?
Just to round it all up, the bars in signal indicator show the strength or quality of the signal you’re getting at your present location. Also, mobile phone makers often use a dull color (like gray) to show weak / absent signal and a bright color (like green and blue) to show good signal.Does the number of bars on my phone affect signal strength?
There is no industry standard that ties cell phone signal strength to the number of bars on your phone. Even the difference between 4G and LTE is murky to most people.How many bars is a good signal?
If your outside signal ranges from: -50 to -79 dBm, then it's generally considered great signal (4 to 5 bars). -80 to -89 dBm, then it's generally considered good signal (3 to 4 bars). -90 to -99 dBm, then it's generally considered average signal (2 to 3 bars).
