PATHLOSS DUE TO TREES ON CAMPUS WIRELESS NETWORK (CASE STUDY OF LAUNET)

This study investigates the impact of trees on signal attenuation in wireless networks, focusing on path loss within a tree-dense environment at Ladoke Akintola University of Technology (LAUTECH). Using a 1.8 GHz frequency router as the transmitter and a spectrum analyzer as the receiver with the aid of rabbit ear antenna, signal measurements were conducted at distances of 10 and 20 meters, with trees as the primary obstruction. Results show significant signal degradation due to tree interference, with increased attenuation at longer distances. The study confirms that tree trunks, branches, and leaves absorb, reflect, and scatter radio waves, leading to measurable path loss. These findings are critical for optimizing wireless network designs in environments with dense vegetation, emphasizing the need for strategic placement of access points and the use of repeaters to maintain strong signal coverage.
