五、Communication & Control
1、4G CAT1 Communication
The system uses 4G CAT1 wireless communication to connect field devices with the cloud management platform.
Compared with short-range wireless technologies, 4G communication is not restricted by the distance between the valve controller and the management center, provided that mobile network coverage is available.
This makes the system suitable for large agricultural areas and distributed irrigation projects.
