Abstract:
Wireless communication is a transmission of information that transmitted using electromagnetic waves such as radio frequencies and infrared. In the wireless communication system, the propagation characteristic of the radio coverage areas is very important to acquire the accurately received signal strength. Acquiring good signal strength on wireless communication depends on the interference that will be an obstruction to the transmission. Wireless communication is more effective and easy to setup because this technology eliminates wires and cables use but the signal can be exposed by many interferences. In this paper, the experiments are conducted in the outdoor communication environments to investigate how much the received signal loss value on the natural environment. Two antennas have been used, which one will be the transmitter and the other will be the receiver on this project. In this experiment, a comparison has been carried out between the transmission with the soft object which is trees and rain weather by the transmission with the trees, rainy weather and boulder. It shows that the signal transmission will degrade their performance when there is obstruction from boulder, tree, and rain.
