Path Loss Measurements for Wireless Communication in Urban and Rural Environments
American Journal of Engineering and Applied Sciences, 2015
Path loss models are useful planning tools that allow the designers of wireless communication networks to achieve optimal levels for the base station deployment and meeting the expected service level requirements. In this study various propagation models (COST 231 Walfisch-Ikegami W-I, Ericsson and Stanford University Interim SUI) are analyzed and compared with the measurements. The measured data were taken in urban (high density region) and rural (low density region) environments at the operating frequency of 1700 MHz using the spectrum analyzer. As one of the key outputs, It was found that the calculations of SUI model fit with the measured data in urban environment.
Propagation Path Loss in Urban and Suburban Area
2013
In this paper, we would discuss the influence of propagation environment in a GSM mobile network. Here we discuss the path loss in urban and suburban areas. The objective of this paper is to develop and optimize a path loss model based on the existing Hata path loss model and outdoor measurement using frequency range from 400MHz to 1800 MHz. The Hata and many other path loss propagation models are compared with the measured data taken in the drive test. The result shows that the measured data and the Hata model are close while the other models undervalue the path loss phenomena. The values for modified empirical parameters of Hata model were developed and presented in this paper. The modification of hata model is given by considering building effects and dust storm effects in the above mentioned area.

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 simulations the selected propagation models have been proposed at the operating frequency of 1800 MHz for different receiver antenna heights in urban and rural environments. Simulations were performed using MAT-LAB R2013b. The propagation models depend on location, frequency range and clutter type such as urban, suburban and countryside. It was noticed from the results of the path loss calculation for 2 m, 7 m and 14 m receiver antenna heights in urban environment that COST 231 (W-I) model showed the lowest path loss results (138 dB) as compared with the other models in urban environment. On the contrary, SUI model showed the highest path loss result (166 dB in 2 m receiver antenna height) as compared with the other models in the same environment.

This investigation deals with the identification of the suitable empirical models for predicting radio wave propagation path losses in Erbil city of Kurdistan region in Iraq. For this purpose, two sites of Korek Telecom operating at 1800 MHz and 2100 MHz have been selected at urban and suburban environments in the city and seven different empirical path loss model named free space model, ECC-33, Stanford Interim University (SUI), Optimized Cost-231, Okumura-Hata, Egli, and Ericson models are tested against experimentally measured path loss values. The path loss was measured experimentally using Sony Ericson handset with complete required equipment and the results are compared to that predicted by each of the mentioned empirical models. The results which have been analyzed through the identification of Root Mean Square Error value achieved by each model revealed that the Optimized Cost-231 and Ericson model provide lowest Root Mean Square Error values.
A Review on Investigation and Assessment of Path Loss Models in Urban and Rural Environment
IOP Conference Series: Materials Science and Engineering
This paper aims at providing a clear knowledge of Path Loss (PL) to the researcher. The important data have been extracted from the papers and mentioned in clear and precise manner. The limited studies were based on identification of PL due to FM frequency. Majority of studies based on identification of PL considering telephonic frequency as a source. In this paper the PL in urban and rural areas of different places due to various factors like buildings, trees, antenna height, forest etc. have been studied. The common parameters like frequency, model and location based studies were done. The studies were segregated based on various parameters in tabular format and they were compared based on frequency, location and best fit model in that table. Scatter chart was drawn in order to make the things clearer and more understandable.However,location specific PL models are required to investigate the RF propagation in identified terrain.

In this research we present the measured path loss values in typical urban and suburban areas at the operating frequency of 3.5 GHz. The measurements are carried out using the spectrum analyzer FSH6 in order to record the channel response. The values of path loss exponent n are calculated for urban and suburban environments. We also compare and analyze the path loss predictions with the measured data. The results of this research confirm that in urban areas the path loss estimation is influenced according to the greater distances. At the beginning of the measurements in urban environment the losses are equal 23 dB after 18 m from the measurement survey. The analysis of measurements centers on anticipating the normal signal quality at the collector set at the given remove from the transmitter as well as the changeability of the signal quality in the specific environment. The acquired from this work results are salutary for planning and installation of any base station with similar to the thoughtful locations environments in order to supply rules for cell arranging of remote communication frameworks as path loss could be a key in calculations within the plan of any radio communications framework system.

In wireless communication, a planned network is given by the path loss model. Link budgeting, coverage prediction, and system performance optimization are indispensable in developing an accurate, simple, and general path loss model. To predict path loss in a particular environment each type of path loss propagation model is designed, it may be inaccurate in another different environment. In this paper, we are trying to predict a path loss model of Durgapur considering a particular place with a mixture of high-rise buildings, suburban , open, and foliage environments. For this proposal, the model area has been divided into twelve sectors taking 30° sectoring of radii 5 km and applying the path loss model for the calculation of path loss.
An empirically based path loss model for wireless channels in suburban environments
IEEE Journal on Selected Areas in Communications, 1999
We present a statistical path loss model derived from 1.9 GHz experimental data collected across the United States in 95 existing macrocells. The model is for suburban areas, and it distinguishes between different terrain categories. Moreover, it applies to distances and base antenna heights not well-covered by existing models. The characterization used is a linear curve fitting the decibel path loss to the decibel-distance, with a Gaussian random variation about that curve due to shadow fading. The slope of the linear curve (corresponding to the path loss exponent,) is shown to be a random variate from one macrocell to another, as is the standard deviation of the shadow fading. These two parameters are statistically modeled, with the dependencies on base antenna height and terrain category made explicit. The resulting path loss model applies to base antenna heights from 10 to 80 m, base-to-terminal distances from 0.1 to 8 km, and three distinct terrain categories.
Investigation of Path Loss Models for Mobile Communications in Malaysia
2011
The design of a propagation path loss model requires knowledge of environment characteristics. Quite a number of propagation path loss models for mobile radio communication system were published in the literature. However, choosing the most suitable model for a given geographical and morphographical area is not a simple task because descriptions of terrain and land-use information can vary widely from country to country. Furthermore, Efficiency of present path loss models suffers when they are used in the environment other than for which they have been designed. The Malaysian geographical and morphographical area varies widely from areas where most models were developed. In addition, several studies in Malaysia, Indonesia and others have shown that the known path loss models perform unsatisfactory when compared with measured data. Hence, this prompts the necessity to investigate the models that suit the Malaysian environment conditions. To investigate the path loss models, measureme...
