Propagation Characteristics of 2.4GHz Wireless Channel in Cornfields

Researches on propagation characteristics of wireless channel in cropland environments will lay the foundation for network deployments of Wireless Sensor Network (WSN) for agricultural information acquirement. In this paper, cropland with corn in maturity stage was selected as the representative of worst-case scenarios for radio propagation within cropland, and the propagation mechanisms and the impact factors on the propagation characteristics of wireless channel in this environment were analyzed. In addition, the power strength Radio Signal Strength Indicator (RSSI) and Packet Loss Rate (PLR) were measured in cornfields, and the node's coverage was further obtained.
