AN ANALYTICAL STUDY FOR THE PERFORMANCE ANALYSIS OF PROPAGATION MODELS IN WiMAX

In this paper, we compare and analyze six different path loss models (i.e. FSPL model, COST 231 Hata model, ECC-33 model, SUI model, Ericsson model and COST 231 Walfish-Ikegami model) in different receiver antenna heights in urban, suburban and rural environments in NLOS condition for WiMAX. We consider Bangladesh as three regions such: Urban, Suburban, flat area and use operating frequency 2.5 GHz. Our observation shows that none of a single propagation model is well suited for all environments. SUI model showed the lowest prediction in urban environment. ECC-33 model showed the heights path loss and also showed huge fluctuations due to change of receiver antenna height. COST-Hata model showed the moderate result and ECC-33 model showed the same path loss as like as urban environment because of the same parameters are used in the simulation. In flat or rural, COST 231 Hata model showed the lowest path loss.
