QoE of social network applications: A study of VoIP quality from Skype vs LINE over 3G and 4G

This paper briefly presents the study of VoIP quality from two popular social network applications over 3G and 4G in Bangkok, covering both stationary and mobility. It has been found that, based-on stationary tests, 4G does not provide better VoIP quality than 3G, although the downlink speed of 4G is faster that 3G by about 5-7 times. However, based on mobility tests called semi-dynamic tests, it can be seen that 4G provides better VoIP quality than 3G obviously.
