Propagation Characteristics of 2.4 GHz Wireless Channel at Different Directions and Heights in Tea Plantation

Abstract:

For configuring wireless sensor networks system and node deployment in tea plantation, this paper researched propagation characteristics of 2.4 GHz wireless channel at different directions and heights in perennial tea plants. Received signal strength and packet loss numbers were obtained by field testing measurements at three directions and two heights. The results showed that different heights of sensor nodes in the tea plants determine the wireless channel propagation characteristics. But the impact of propagation directions on wireless signal is weaker. Besides, validation results show that it s best to deploy the sensor nodes antennas on the top of the tea canopy or above of it in the tea plantation. This research can provide technical support for WSN application in tea plantation.
