Abstract: This paper concerns about the radio propagation models used for the upcoming 4th Generation (4G) of cellular networks. A comprehensive review of the propagation prediction models for 4G wireless communication systems is presented and computation of path loss due to specific terrain and clutter environment has been carried using MATLAB based simulations for various prediction techniques such as COST-231 Hata model, COST-231 Walfish-Ikegami method, SUI model and ITU-R(1411.1) model for broadband and mobile services. The results showed that COST-231Hata’s method gave better agreement in terms of path loss values in urban, suburban and rural areas as compared to COST-231 Walfisch–Ikegami model. COST-231 Hata model shows the lowest path loss in all the terrains whereas ITU-R(NLOS) model has highest path loss values. The prediction errors of the SUI and ITU-R NLOS models are considerably higher than those of the COST-231Hata and COST-231 Walfisch– Ikegami models.
