7.2 Range Test
After establishing communication between node and gateway, use the range test feature in
SensorConnect to monitor the signal strength and to optimally position the nodes, gateway, and
antennae for installation. Maximum achievable range is determined by the gateway and node
power settings (found in the device Configure menu) and is highly dependent on the physical
environment surrounding the devices.
7.1.1.1 Select the node name > Range Test

7.1.1.2 RSSI is a measure of signal strength between the node
and the base station. A higher RSSI value (closer to
zero), will result in better node to base station
communication. Reliable communication can be achieved
with a signal strength greater than -75 dBm, in the
absence of radio frequency interference. Position the
node and gateway antennas where the best RSSI value
is observed.
