For the cell design of mobile communication systems, the path loss prediction models are very important. These models can be classified into theoretical and experimental models. The main experimental models are the Okumura-Hata, Cost231-Hata, and ITU-R model. The problem of these models is that...
The aim of this paper is investigate the performance of various path loss models in different environments for determination of the signal strength with respect to various frequency ranges and distance for wireless network. There are five path loss models, namely Free Space, Log-distance, Log-norma...
In this research various channel propagation models of wireless communication systems were analysed. There are many types of propagation models that can minutely calculate the path loss in all types of terrain. Performance estimation of different propagation models was analysed using simulations. In the...

Based on measurements, the in-leaf and single-slope path loss models are presented. The path loss exponents for the dual-mobility channels are found to be between 2.1 and 3.4 in urban and 8.0 in forest, with higher reference when antennas are placed inside the vehicle....
The results indicated that, as plant height increased, path-loss and PDR became more correlated with each other. A distance of 70 m was defined as a stable communication distance for 2.4 GHz in-field WSN applications. Four models were developed to predict the path-loss based on the log of...
In this paper we make use of a large set of measurements from a production wireless network in rural New Zealand to analyze the performance of 28 path loss prediction models, published over the course of 60 years. We propose five metrics to determine the performance of each model. We show ...
