Abstract

An accurate propagation modeling of radio waves propagation is very important task in cellular network design as it provides the detailed useful knowledge about the wireless channel environment characteristics. Theoretical or empirical RF propagation models provide the required useful information about the signal path loss and fading to evaluate the received signal level, the coverage area, and the outage probability in specific regions. This paper aimed to develop an empirical radio wave propagation model based on observations and sets of measurement data collected from different sites through drive test. These measurements are used to determine the received signal power at some locations to create an empirical radio wave propagation model that is suitable to be appropriate in cellular network accurate design and link budget prediction at the city of Baghdad.

Highlights

The widespread demand for cellular communication service has lead mobile communication operators to use micro-cellular technology to face the extraordinary increasing in the number of subscribers
The reliable cellular mobile radio design heavily depends on accurate prediction of transmitted signal attenuation, and local field variations [1], [2]
The RF propagation model is a set of mathematical equations or algorithms through which the received signal strength or the path loss can be predicted in specific regions [2]

Summary

Introduction

The widespread demand for cellular communication service has lead mobile communication operators to use micro-cellular technology to face the extraordinary increasing in the number of subscribers. The reliable cellular mobile radio design heavily depends on accurate prediction of transmitted signal attenuation, and local field variations [1], [2]. The RF propagation model is a set of mathematical equations or algorithms through which the received signal strength or the path loss can be predicted in specific regions [2]. This paper aimed to determine the path loss exponent value in urban places at the city of Baghdad, and to develop an empirical radio propagation model that be appropriate in Baghdad. This will be carried out through the received power measurements for different distances in several cellular sites at the city.
