This Recommendation proposes a testbed setup and a methodology to evaluate the QoE of the multiple 5G and beyond mobile use cases. A testbed, its calibration, and a testing methodology are described, able to provide consistent and repeatable results in an automated fashion. A key focus of the setup is the use of commercial devices and applications, aiming at making results more valuable by mimicking the setup of a real user. This document focuses on cellular 3GPP networks. A similar setup could be thought of using other technologies, e.g., Wi-Fi, also interoperating to emulate inter-RAT handovers, although it will not be covered here.
