China Mobile to launch 4G voice service

China Mobile Ltd, the world's largest telecom operator by subscriber number, aims to start the commercial use of Voice over LTE - an approach to deliver voice services as data flows - by 2014. Li Yue, its chief executive officer, said on Wednesday that VoLTE has many advantages if you compared it with other old-fashioned voice-calls. "VoLTE allows a more efficient use of wireless network resources, at a lower cost, with higher capacity," Li said at Mobile Asia Expo held in Shanghai. In addition, VoLTE is an approach capable of introducing high-definition voice and video, he added. China Mobile plans to start comprehensive testing of VoLTE in the third quarter of this year, hold a small-scale field trial in the fourth quarter, and launch in the fourth quarter of 2014, Li said.
