Comparison of Asset and Atoll Cellular Planning tools for LTE Network Planning Hormoz Parsian 85014K Department of Communication and Networking Supervisor: Prof. Jyri Hämäläinen Instructor: Dr. Kimmo Mäkeläinen This Master’s thesis was conducted at Nokia Siemens Networks 5/22/2012 1 Outline of the work: ã Introduction Background Research question Methodology ã Propagation Models Hata Models Standard Propagation Models in the Tools Deriving Equivalent Parameters ã Coverage Analysis Coverage Analysis with srcinal constant term in Atoll propagation model Coverage Analysis with optimum constant term in Atoll propagation model ã Interference Analysis Analysis of Number of Covering Cells in Asset Interference Analysis for Outdoor Users Interference Analysis for Indoor Users ã Capacity Analysis Capacity Analysis of LTE services Capacity Analysis for MIMO modes Capacity Analysis of Scheduling Algorithms ã Conclusions and Future Works 5/22/2012 2 Introduction ã Backgrond ã Software for network planning : Astoll of Forsk Asset of Aircom Planet of Mentum ã Planning tool manufacturers design their tools independently of each other ã Users do not know before testing whether different planning tools produce comparable performance estimates for a given network ã Sometimes a network is planned or investigated in two different planning tools ã Companies often change from one planning tool to another Planning results of the first tool have to be reproduced in the second one 5/22/2012 3 Introduction ã Research Question ã Comparing two planning tools, Atoll of Forsk and Asset of Aircom with respect to LTE network planning Not trying to find out which of the tools is better than the other one Trying to investigate whether they provide comparable performance measures in the test network ã Tools’ performance can be close to each other if two investigated network configurations and other configurations like propagation models are equal to each other. ã Finding equal parameters mean they produce same performance estimates AND it necessary does not mean numerically equal parameters ã LTE input parameters for Asset and Atoll, prepared by NSN to give equal performance estimates 5/22/2012 4
