Multimedia streams have increased dramatically over the wireless networks during the last few years. 3D video stream-based applications and movies will become significant contents of wireless network traffic in future Internet. This paper shows Quality of Experience (QoE) results based on transport network’s Quality of Service (QoS) level degradation obtained from subjective tests which were carried out for 3D stereoscopic video files transporting through GPON-based transport network combined with IEEE802.11n standard based WiFi sub-networks on clients’ side. Gathered information show that QoE level is influenced with more factors like: bandwidth limitation or channel interference in WiFi network and QoS parameters’ values of transport network as well. In case of 3D contents quality of film shooting, size and resolution value of using display also take effect on perceived visual quality. Evaluation results were processed statistically IBM SPSS Statistics software-package.
