Performance analysis of VoWIFI on RAN
Yan Xin Yang, Yong Qiu, Tao Zhang · 2017
With the rapid development of wireless technology, free or cheap voice communication has become more and more popular. But this cost-effective voice technology based on Wi-Fi, Voice over WIFI (VoWIFI), is lacking mature management and control system, especially there is still no relevant research on its RAN performance. This paper has three mainly contributes: 1) in the indoor environment, we studied the relationship between voice quality and signal quality of Wi-Fi; 2) in order to achieving high performance to improve the users' QoE, two types of voice quality are compared of the VoWIFI with VoWIFI only and VoWIFI adding download service, 3) according to the experimental data, an estimate method is proposed and verified for the VoWIFI performance based on signal quality of Wi-Fi.
