Abstract: This paper aims to investigate the performance of various path loss models in different environments for determination of the signal strength with respect to various receiver antenna heights for wireless network at 2.4GHz unlicensed band. A total of seven path loss models, namely Free Space, COST-231 HATA, ECC-33, SUI, HATA, COST-231 WI, HATA and Ericsson models have been reviewed with different receiver antenna heights in urban, suburban and rural environments. The estimated results produced by Free Space model were used as reference values. All estimated results of reviewed models were compared with the reference model values. It was found that COST-231 HATA model demonstrated highest path loss with 39% more values than reference model in urban environments. Ericson model established highest path loss values with 55% and 77% more estimated results than reference model in suburban and rural environments respectively. COST-231 WI model executed the lowest path loss amount with 12.6% more values than reference model in rural environments. SUI model established the results with 10% difference as compared to reference model at lower receiver antenna heights. It was revealed that the models results were incongruent due to incorporation of different variables and terrain classification. Therefore, a particular model cannot be recommended for the estimation of path loss at various antenna heights in all environments. However, SUI model could be preferred due to better performance in terms of less path loss as compared with the results of reference model at lower receiver antenna heights for suburban and rural environments.
