Frequency Domain Measurements of Radio Channels in a Typical Agriculture Environment

Wireless connectivity is a critical part of each Internet of Things (IoT)-based “smart” agriculture system, as it enables the real-time transmission of data collected by sensors in agricultural fields. In this work, the empirical data for the physical characteristics of radio channels in the frequency range of 0.8 GHz to 1 GHz are presented for a more effective node arrangement during the design and deployment of wireless networks for IoT-based smart agriculture. The results indicate that path loss increases with distance and all radio channels exhibit multipath behavior.
