Automation in agriculture requires massive use of sensors, deployed over a vast areas of farmland, with:

• Low-Power for long lifetime
• Long-Range
• Low-Complexity to reduce cost in massive deployments and increase robustness of outdoor hardware.

Sensors need to measure in regular or sporadic intervals, temperature, moisture, nutrition levels, etc. to efficiently operate irrigation and fertilization systems. Additionally, drones can harvest crops from the fields, or the information from sensors, which will introduce mobile and sporadic communication.
