A new generic model for signal propagation in Wi-Fi and WiMAX environments

Abstract

The ability to accurately predict radio propagation behavior for wireless communication systems, such as cellular mobile radio, is becoming crucial to system design. Since site measurements are costly, propagation models have been developed as suitable, low-cost, and convenient alternative. In this paper, we will propose a new generic signal propagation model for Wi-Fi and WiMAX environments. To develop this model we used existing models which are classified as: Free space models and land propagation models. This includes different types of loss: path loss, slow fading (shadowing) and fast fading. Our aim is to have a flexible model to be applicable in indoor and outdoor environments. Experiments carried out for indoor Wi-Fi and outdoor WiMAX cases have shown excellent results for the proposed model.
