Comparative study on radio wave propagation models for 4G network

This paper is about comparative study on the radio wave propagation models for the Fourth Generation Mobile Network known as Long Term Evolution Advanced (LTEAdvanced). The selection of radio wave propagation model is essential as the propagation model is able to estimate and predict the radio wave propagation path loss value between the transmitter and receiver for different types of environments. From the preliminary results, it shows that COST-231 Hata model produce higher path loss value due to it is only applicable for LOS situation and macro cell environment as the model does not consider radio wave propagation reflections and shadowing. In contrast, COST-231 Walfisch-Ikegami is applicable for both LOS/NLOS situations and both macro and micro cell environments because the model considers radio wave propagation reflections and shadowing.
