    Comparative Analysis of Path Loss Prediction Models for Urban Macrocellular Environments

    COMPARATIVE ANALYSIS OF PATH LOSS PREDICTION MODELS FOR URBAN MACROCELLULAR ENVIRONMENTS A. Obota, O. Simeonb, J. Afolayanc Department of Electrical/Electronics & Computer Engineering, University of Uyo, Akwa Ibom State, Nigeria. aEmail: [email protected] bEmail: [email protected] cEmail: [email protected] Abstract A comparative analysis of path loss prediction models for urban macrocellular environments is presented in this paper. Specifically, three path loss prediction models namely free space, Hata and Egli were used to predict path losses. The calculated path loss values were compared with practical measured data obtained from a Visafone base station located in Uyo, Nigeria. The comparative analysis reveals that the mean square error (MSE) for free space, Hata and Egli were 16.24dB, 2.37dB and 8.40dB respectively. The results showed that Hata's model is the most accurate and reliable path loss prediction model for macrocellular urban propagation environments, since its MSE value of 2.37dB is smaller than the acceptable minimum MSE value of 6dB for good signal propagation.

Considerable efforts have been devoted to the statistical modeling and characterization of these different effects, resulting in a range of models for wireless channels which depend on the particular propagation environment and underlying communication scenario. The comparative analysis of different theoretical and empirical propagation models, such as Okumura, Hata, COST-231 Hata, and Longley-Rice, is given in this paper. After a brief introduction and description of these models, we present some numerical results using MATLAB and RadioWORKS. INTRODUCTION Radiowave propagation through wireless channels is a complicated phenomenon characterized by different effects such as reflection, diffraction and scattering phenomenon. An exact mathematical description of this effects is either too complex for tractable communication system analysis, although considerable efforts have been devoted to the statistical modeling and characterization of wireless channels. In this paper we will characterize the variation in received signal power over distance due to path loss and shadowing. Path loss is caused by dissipation of the power radiated by the transmitter as well as effects of the propagation channel. Path loss models generally assume that path loss is the same at the given transmit-receive distance, which means that path loss model does not include shadowing effects.

    Calculation of the coverage area of mobile broadband communications. Focus on land Antonio Martínez Gálvez Master of Science in Communication Technology Submission date: March Terje Røste, IET Supervisor: Norwegian University of Science and Technology Department of Electronics and Telecommunications Problem Description The task is to study the principles and models for calculating transmission loss in radiopropagation in mobile systems for land. Recent models are Okumura et. al [1], COST 231 [2], Bullingtons model [3], Epstein and Peterson's model [4], Picquenards model [5] and a modification of Walter Hill [6]. Another option is to look at Radar Ray Trace models. One must choose to proceed with one or two of these principles in a deeper studium. Furthermore can study Teleplan ASTERIX program (which is made available to the department) for prediction of transmission loss and describe how this program may be further developed with improved models. If time permits can simple modification of ASTERIX performed and tested. It focused on the frequency ranges 800 MHz and 2.6 GHz. Assignment given: 31. August 2009 Supervisor: Terje Røste, IET Abstract This thesis aims to provide information about what different propagation prediction models must be the adequate ones for the radio planning of an LTE network. In the initial phase, a study of different propagation models was done mainly over COST231 and ITU-R P. Recommendations, emphasizing over the ones for diffraction over rounded obstacles and paths over sea as a recommendation from Teleplan AS. Matlab code is also presented since it was tried to test the convenience of the use of ITU-R P.1546 over sea paths and to compare Lee Model with ITU-R P.526 for rounded obstacles.

    Progress In Electromagnetics Research M, Vol. 61, 133–146, 2017 Comparative Analysis of Basic Models and Artificial Neural Network Based Model for Path Loss Prediction Julia O. Eichie1, *,OnyediD.Oyedum1, Moses O. Ajewole2, and Abiodun M. Aibinu3 Abstract—Propagation path loss models are useful for the prediction of received signal strength at a given distance from the transmitter; estimation of radio coverage areas of Base Transceiver Stations (BTS); frequency assignments; interference analysis; handover optimisation; and power level adjustments. Due to the differences in: environmental structures; local terrain profiles; and weather conditions, path loss prediction model for a given environment using any of the existing basic empirical models such as the Okumura-Hata’s model has been shown to differ from the optimal empirical model appropriate for such an environment. In this paper, propagation parameters, such as distance between transmitting and receiving antennas, transmitting power and terrain elevation, using sea level as reference point, were used as inputs to Artificial Neural Network (ANN) for the development of an ANN based path loss model. Data were acquired in a drive test through selected rural and suburban routes in Minna and environs as dataset required for training ANN model. Multilayer perceptron (MLP) network parameters were varied during the performance evaluation process, and the weight and bias values of the best performed MLP network were extracted for the development of the ANN based path loss models for two different routes, namely rural and suburban routes. The performance of the developed ANN based path loss model was compared with some of the existing techniques and modified techniques.

Path loss models uses set of 3.5GHz (licensed) and 5.8GHz (unlicensed) frequency bands. mathematical equations and algorithms for prediction of path Path loss models can be used to find Received Signal Strength loss values. Such models are categorized into three categories (RSS) which is an important factor in deciding handover. If RSS i.e. deterministic (uses physical law leading propagation of is less than a particular threshold value then handover decision is to be taken. For our analysis we have taken Free space waves), Empirical (based on measurements and observations) Propagation, ECC-33, COST 231 Hata, COST 231 W-I and SUI and stochastic (uses series of random variables) models. In models compared w.r.t. different environment (high density, our study we use only empirical models which are described medium density and low density) and different height of as follow. receiving antenna (2m, 6m, and 10m).

    Radio Propagation Modeling on 433 Mhz

    Radio propagation modeling on 433 MHz Ákos Milánkovich1, Károly Lendvai1, Sándor Imre1, Sándor Szabó1 1 Budapest University of Technology and Economics, Műegyetem rkp. 3-9. 1111 Budapest, Hungary {milankovich, lendvai, szabos, imre}@hit.bme.hu Abstract. In wireless network design and positioning it is essential to use radio propagation models for the applied frequency and environment. There are many propagation models available for both indoor and outdoor environments; however, they are not applicable for 433 MHz ISM frequency, which is perfectly suitable for smart metering and sensor networking applications. During our work, we gathered the most common propagation models available in scientific literature, broke them down to components and analyzed their behavior. Based on our research and measurements, a method was developed to create a propagation model for both indoor and outdoor environment optimized for 433 MHz frequency. The possible application areas of the proposed models: smart metering, sensor networks, positioning. Keywords: Radio propagation model, 433 MHz, smart metering, positioning 1 Introduction We are accustomed to use various wirelessly communicating devices, which possess different transmission properties according to their application areas. There are devices operating at high bandwidth in short range, but can not percolate walls. On the contrary, other devices can penetrate all kinds of materials for long distances, but operate on lower bandwidth. The transmission properties of these various technologies – beyond transmission power and antenna characteristics – are principally determined by the operating frequency range of the system. In addition, the operating frequency determines the amount of attenuation for the technology, caused by different media. The ability of calculating the signal strength in a given distance from the transmitter is severely important in case of network planning, because such a model helps us to determine where to place the devices, so that the system operates properly.
