2. INTRODUCTION

2.1 ORIENTATIONOFTHEPROPOSEDSTUDYEach environment is characterized by its unique

terrain profile [1].

Each Propagation model is designed to cater for aspecific terrain profile.

Propagation models can however be corrected to

fit another terrain profile.[1]

2.2 STATEMENTOFTHEPROBLEM

Measure and calculate the amount of fading that

will be encountered by a wave

2.4 SIGNIFICANCEOFTHESTUDY

The propagation model will greatly assist in

designing a networks that efficiently maximizes

the spectrum allocated.

Designing a network without a propagation modelleads to tedious and inaccurate work.

Help select the best location for setting up base

stations

3. LITERATURE A communication system

Source: refer to [2]

The propagation path has many different obstructions,

such as trees and buildings[1].

The field strength strongly depends on local

environment [2]8

3.2 PROPAGATION PATH-LOSS MODELS

3.2.1 Free space model It calculates radio signal propagation attenuation in free space with

no nearby obstacles to cause reflections or diffractions[3]

3.2.2 Hata model Hata presented the urban area propagation loss as a standard formula

and supplied correction equations for application to other

situations[3].

3.2.3 COST-321 model

It is suitable for medium and large cities where the base station

antenna height is above the surrounding buildings. The terrain

configuration is only partly taken into consideration[3].9
