Indoor Radio Network Planning:Coverage And Capacity Planning Of Small Cells For Buildings

Abstract

Indoor Radio network planning has been a long-standing problem since the very starting commercialization and business of indoor mobile communications sys tem ,of which power coverage and capacity coverage are the two major objec tives.Indoor RNP of a new Radio interface such as Small cell LTE needs new tools and competencies.The introduction of pico cell and femto cell driven small cell technology and comparison of pico cell and femto cell, in small cell technology ,makes network planning challenging. In this work,coverage and capacity estimation of pico cell and femto cell network was performed for future network deployment.Our designed network femto cell were improved by 12.23% and pico cell by 9.06%.Femto cell network coverage and capacity is best as compared to pico cell network .In the case of coverage planning,Radio link budget together with important link level simulations was performed to determine path loss.Comparison of path loss models were used to select the best model. A COST Multiwall winprop path loss model was used to determine the cell radius per morphology.For capacity evaluation,data rate,throughput analysis,and impor tant system level simulations was performed to know subscribers supported per site.Cell edge throughput and Receiver Sensitivity was determined as the measure of performance and effectiveness for capacity analysis. Finally,coverage target number of sites,capacity target number of sites,and the fi nal limiting site count was determined.
