Explanation on how to read and determine the displayed info
For the “Signal Strength”, if you are in the 100 area (that means -100 dBm), you will be transmitting at maximum power (2 Watts), and since coverage is hit and miss at this weak a signal, you may end up transmitting many times before the packets make it through. This might help explain any poorer than normal battery life. We consider anything at -85 to -40 excellent.
