The impact of RF parameters on perceived QoS in cellular mobile networks

Abstract

This paper targets empirical voice and video quality assessment in mobile networks and presents fundamental QoS testing methods in correlation to RF indicators. The paper focuses on the most critical performance parameters for real-time services (e.g. voice) such as call drop vs. poor coverage in UMTS. The empirical study was based on a clearly defined drive test scenario with predetermined routes and communication profiles such as mobile to data server and call server setup.
