Planning 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.

• 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.

This illustration shows how installation height affects general transmission distances. Many 
variables affect transmisstion distance. Results will vary based on environmental conditions. To 
extend range, see Appendix A: Using a Long Range External Antenna, page 17.
