Keywords: Skype, Viber, Video quality, LTE
In today's world communication, many applications have been developed for user equipment (UE) that supports VoIP (Voice over IP), multimedia, text and data services in mobile telecommunications. Despite voice call as the basic communication, on-demand service is also video as advance way of communication. To have a video communication in LTE (Long Term Evolution) network, mobile operators should provide good radio conditions and enough bandwidth to support multimedia communications in general and video communication particularly. To achieve the required quality of multimedia communications via different applications, operators need to improve the coverage and the throughput capacity in wireless technology. This paper shows the results of the video quality measurements for Skype and Viber applications, in different radio propagation conditions in LTE network. Utilization of throughput and modulation schemes used during the communication are also measured and analyzed. Recorded video sequences are evaluated based on the feedback from the people (users) involved in the evaluation process. Mean Opinion Score (MOS) method was used as evaluation method.
