Although the literature on Quality of Experience QoE has boomed over the last few years only a limited number of studies have focused on the relation between objective technical parameters and subjective user-centric indicators of QoE. Building on an overview of the related literature this paper introduces the use of a software monitoring tool as part of an interdisciplinary approach to QoE measurement. In the presented study a panel of test users evaluated a mobile web-browsing application . Wapedia on a PDA in an IEEE g Wireless LAN environment by rating a number of key QoE dimensions on the device immediately after usage. This subjective evaluation was linked to the signal strength monitored during PDA usage at four different locations in the test environment. The aim of this study is to assess and model the relation between the subjective evaluation of QoE and the objective signal strength in order to achieve future QoE optimization. 1. Introduction
