The Quality of Service of the Deployed LTE Technology by Mobile Network Operators in Abuja-Nigeria

Abstract


In this study, Long-term evolution (LTE) cellular system practical performance analysis focused on-field results obtained from mobile network operators (MNOs) namely MTN, GLO, Airtel, and 9Mobile in Nigeria. MNOs utilize the 5MHz, 10MH, and 20MHz channel bandwidths based on 3GPP’s (Third-Generation Partnership Project’s) standard. The presented analysis shows the Uplink (UL) and Downlink (DL) throughputs in mobility conditions in addition to other sections of Long Term Evolution system quality of service (QoS) key performance Indicators (KPI’s) of connection drop rate, connection failure rate, peak physical downlink throughput, minimum radio link control (RLC) downlink throughput threshold and latency. Comparative studies are performed between the Nigerian MNOs and it was observed that MTN provides the best QoS. The introduction of novel LTE QoS metrics herein referred to as National Independent Wireless Broadband Quality Reporting (NIWBQR) is the major contribution of this study. The goal of this study is to show the quality of the network as it affects users' experience. It was clearly shown in the study that all the MNOs are not adhering to the 3GPP’s specified user plane latency of 30ms and control plane latency of 100ms respectively. Which makes video streaming and low latency communication a near-impossible task.
