5G Radio Network Dimensioning And Millimetric Wave Propagation Modeling: The Case Of Kirkos Subcity, Addis Ababa

Abstract

The ongoing progress in request for improved mobile quality, higher data rates, and lower latencies are motivating the development of the network to 5G. The advancement of wireless communication technologies and the increasing scope of radio network make the tasks of radio network planning more challenging and attention has to be given for nominal and the desired requirements after deployment. The nominal and detailed 5G radio network dimensioning involves consideration of basic network requirements in terms of coverage prediction, capacity and Quality of Service (QoS). In this thesis, the significance of such basic requirements has been demonstrated using mathematical analysis and Radio network planning and optimization (RNPO) software i.e Winprop tool in order to disclose 5G’s radio network planning strategies to the operator and local practicing engineering in the target area. This thesis considers Kirkos sub city in Addis Ababa, with the area of 14.91 ���� 2. The simulation result output contains coverage prediction by pathloss, Signal strength (Reference signal received power(RSRP), Reference signal received quality(RSRQ)), Capacity analysis by throughput and SINR (Signal to interference plus noise ratio) and Quality of services that validate the deployed radio network that can handle the cellular traffic of Kirkos sub city in Addis Ababa. Since the real Addis Ababa digital map is used, from which Kirkos Subcity is cut out of this city by using Winprop(Wallman) software. From the coverage and capacity planning perspective of the 5G New radio 57gNodeB’s (from Coverage planning) and 44gNodeB’s (from Capacity planning) are obtained respectively for Kirkos Subcity, from which the maximum of the two is deployed.
