Attribute Description
RSSI This is the Received Signal Strength Indicator. It represents the received power of
the signal. This number will always be a negative value.
To maximize the performance of this system, get the RSSI value as close to zero as you
can. If you are working to maximize this Watchdog Wi system, the RSSI value will likely
plateau close to -30. The closer you can get your reading to -30, the better performance
you’ll see.
LQI This is the Link Quality Indicator. It is an indication of the level of noise that’s
disrupting the radio. This number will always be a positive value. To maximize the
performance of this system, work to get this value as close to zero as possible. High LQI
values - above 25 or 30 - indicate a noisy environment.
