Abstract:


(WiMax) is a wireless broadband technology based on IEEE 802.16 standard. WiMax has two potential access conditions; Line-of-Sight condition, and Non-Line of Sight condition. In Non-Line of Sight condition a Path Loss arises when an electromagnetic wave propagates though space from transmitter and receiver. Prediction of WiMax path loss is a fundamental tool for designing any broadband wireless communication system. Several models are available to estimate the path loss, such as: COST 231-Hata model, Hata-Okumura model, COST 231 Walfish-Ikegami (W-I) Model , Stanford University Interim model, and Ericsson model. In this paper , we aim to simulate the propagation path loss models using MATLAB software. This simulation is done based on the variation of the distance between the base station and the receiver in the range of 0.5 km to 5 km, for different height of the receiver antenna 3, 6, and 10m, within the operating frequencies 2.5 GHz, and 3.5GHz. All simulations carried out separately for urban, suburban, and rural environment. The simulation results of all models are compared and analyzed to identify a suitable model in different environments. The comparison and analyses are done based on the influence of variation of the distance between the transmitter and receiver, the operating frequency, and the receiver antenna height on the path loss prediction.
