Abstract
The worldwide telecom industry is moving toward 5G network to address high bandwidth,
low latency, and massive connectivity requirements. The recent deployment of 5G NR
technology in Ethiopia promised to transform the speed and quality of MBB services in
majority of the business districts and selected residential areas of Addis Ababa.
To achieve expected outcomes from this new 5G network, its quality and perception
of customers should be evaluated in its early stage. This will enable timely and informed
measures by subscribers, mobile network operators, mobile device manufacturers, the
regulatory authority, ECA, and other stakeholders. In this thesis, spatiotemporal evaluation
of QoS metrics-download throughput, upload throughput and latency-is conducted using
crowdsourcing application, Ookla SpeedTest, Network performance reporting system, PRS
and drive test tool, PHU. A subjective survey is used to assess user experience.
Despite the significant disparity in 5G coverage, result from all four sources indicate
that 5G eMBB service performance in AA is very good as compared to average global 5G
performance and IMT-2020 minimum technical requirements. Overall average download
throughput obtained is 364 Mbps from SpeedTest, 311 Mbps from PRS and 414 Mbps
from PHU. And average upload throughput is 58 Mbps from SpeedTest, 20 Mbps from
PRS and 89 Mbps from PHU. From subjective survey, MOS on the overall performance
of 5G eMBB service in AA is 4.1. The results also show a consistent trend regarding the
impact of spatiotemporal and device variations on the performance of 5G network.
