Abstract: Radio wave propagation models are recently important for wireless network designer while designing the specific network design in definite regions, building and infrastructure. There may be some problems when using and designing indoor wireless network. It causes signal attenuation because of complex structure and infrastructure of building and other unwanted effect of carrier frequencies. To overcome these problems, nowadays the estimation of path losses becomes the main challenge. Moreover, while moving mobile objects move around the building and campus, the estimation of path loss values become more complex and hard to define.
