dc.description.abstractThe demand for wireless communications systems is ever increasing in all the human- life activities. This technology provides connectivity also where wiring is impossible or costly. Wireless technology can range from WLANs and cellular networks to headphones and microphones connections. It includes infrared (IR) devices, such as remote controls, cordless keyboards, and mice, all of which have a transmitter and a receiver. The high diffusion rate of this technology provoked some confusion in the user, as the industry developed many different wireless systems and services, which often were not able to interact with each other. The purpose of this study and research was to understand the concept of channel modeling and ray tracing. During the project different mechanisms and their impact was observed on a signal and their effect was calculated. An area with predefined specifications was modeled and the path of the signal from the transmitter to receiver was examined. Many scenarios were taken under consideration. The phenomenon like knife-edge diffraction, simple and complex shadowing and ray models were implemented and the result for every individual phenomenon was observed. The reasons for the loss of field strength and increase in path loss were studied, through changing different parameters like heights of the transmitter and receiver while moving along streets. All these observations were performed in MATLAB.en_US
