Planning Your System
Before installation, plan your system. After determining which sensors you want and
where you want to install them, make sure you have the correct number of Nodes to
support those sensors.
The maximum distance between two Nodes and a Gateway and a Node will vary
depending on many factors including environment, height, terrain and RF noise.
To get optimal transmission range:
• Ideally, locate the devices with unobstructed lines of sight between them. A large
hill or large metal barrier will block signals. If transmitting under a canopy or in
an orchard, range will be reduced.
• Mount the devices as high above the ground or the highest crop height as
possible. The higher they are mounted, the longer the transmission distance, as
shown below.
• The Gateway should be placed in a window or as close to the outside of the
building and as close to the Nodes as possible; higher is better.
