The FieldNet Wireless Irrigation Network is designed to allow one to control his entire center-pivot irrigation system, check the status and position of each pivot, and monitor water usage via computer and now smartphone. FieldNet's Internet-accessible web portal allows for pivot configuring, monitoring, and adjusting, pivot status updates, networking of the pivot controls (regardless of brand), and programming of end guns, pivot speed, and chemical injection for water/chemical application. The basic package, which includes radio-to-Internet bridge, radio repeater to extend communication range, and pivot remote telemetry unit, can be upgraded to meet expanding irrigation system needs with new and more sophisticated FieldNet accessories over time.
