Signal
Strength
Standard 5-bar signal strength indication; a minimum of two bars is suggested for
reliable use.
Signal strength indicators
The
weighted dBm
measurements are negative numbers, meaning the smaller negative values
denote a larger number. So, for example, a
-85
is a better signal than
-90
.
Note
For more information regarding how signal strength is calculated and subsequently displayed via
the LED indicators, refer to

Signal bars explained
The LTE signal status bars are calculated using various algorithms based on the network type it is
connected to. For 4G LTE, the RSRP, SNR, and RSSI values are all factored in to determine the
reported signal strength bars. For 3G networks (including HSPA+) and 2G networks, the signal
strength bars are determined by the RSSI value.
