WORK SCREEN 1 –UPLINK AND DOWNLINK DEMODULATION MARGIN
First work screen appears just after device switch on. Herewith the data is not available on
it. Work screen 1 allows you to get the follow information:

Number of visible gateways;

PER coefficient – percent of successful transmissions;

Margin demodulation diagrams and numerical values of UM and DM of the last
session.
Margin demodulation is the positive integer value displayed in dBm and indicating how much
received signal above the demodulation threshold. ‘0’ value means that the packet was received
on the bottom of demodulation (0 dBm), whereas, for example, ‘20’ value means that the packet
was received on 20 dBm above the demodulation threshold.
from 0 to 5 Communication on the brink of failure, unstable connection to the network
from 5 to 10 Border zone, stable communication is not guaranteed
above 10 Good signal strength, confident communication
DM – Downlink Margin demodulation
