A Modified Approach to Calculate the Path Loss in Urban Area
نویسنده
چکیده
The propagation path loss models may give different results if they are used in different environments other than in which they were designed. In this paper we compare the different path loss propagation models with measured field data and find out the model which is giving results nearer to the field measured data. In this we used many path loss models For comparative analysis. The field measurement data is taken in urban (high density region) environment in INDIA at 900 MHz &1800 MHz frequency with the help of spectrum analyzer. After analyzing the results Okumara model shows the better results in the specified environment. To attain more reliability in the existing Okumara model for the area specified we given correction factor using some existing assumptions.

A Modified Empirical Path Loss Model for 4G LTE Network in Lagos, Nigeria
The quality of signal at a particular location is essential to determine the performance of mobile system. The problem of poor network in Lagos, Nigeria needs to be addressed especially now that the attention is toward online learning and meetings. Existing empirical Path Loss (PL) models designed elsewhere are not appropriate for predicting the 4G Long-Term Evolution (LTE) signal in Nigeria. T...
متن کاملUrban Sprawl Pattern and Its Implications for Urban Management (Case Study: Zaria Urban Area, Nigeria)
Urban sprawl, or the unplanned and uncontrolled spreading out of built-up areas in Zaria urban area causes problems of congestion, poor urban basic infrastructure delivery and poor urban planning. This paper analyzed the pattern and implications of urban sprawl using GIS and Remote sensing as an improved approach to analyze and explain sprawling beyond the traditional spatial or cartographic ma...

In recent decades, population growth and progress of technology have shaped large and compact urban settlements. Existence of huge transportation systems and developed urban infrastructures are among the most important properties of modern cities.

متن کاملVolume-Based Imperviousness for Storm Water Designs
The concept of low impact development LID is to apply decentralized on-site runoff source control to preserve the watershed hydrologic and ecological functions. An integrated layout using bioretention and vegetated landscape can decrease the developed runoff volume and peak flow. One of the key factors in urban hydrology is the imperviousness in the watershed. The conventional approach is to we...
متن کاملStructure of Production with Urban- rural income Inequalities in the Framework of Structural path Analysis: The Case of Iran
The first experimental SAM for Iran was constructed more than three decades ago under the supervision of Prof. Pyatt. Based on this work Prof Pyatt had observed that the way in which Iran was spending oil revenues was likely to exacerbate urban—rural income differentials in Iran. In his approach to SAM he did not distinguish between factorial and institutional income distributions preferring to...
