VoLTE & WebRTC
The appearance of WebRTC (Web Real-Time Communication) enables Web browsers capabilities to provide real time peer-to-peer video and voice transfer within the browser via a simple JavaScript API. Users can speak to each other directly between browsers rather than through a server. Telecom operators can connect 3G or VoLTE voice with browsers and further develop new digital services.
VoLTE should bring strong competitiveness in telecom operators, but success depends on interoperability among browsers and compatibility with video codecs. Support from companies like Apple, Samsung and Microsoft is imperative.
WebRTC is still in its early stages and SK Telecom is experimenting with the technology in its labs. SKT recently uploaded WebRTC on its IMS infrastructure where the developer community has shown tremendous interest. The Korean telco plans to create a development-favorable environment allowing developers to easily access and develop diverse services.
VoLTE is finding traction in Asia and is helping telcos drive ARPUs with LTE. The success of VoLTE in the long run seems positive, as carriers around the globe are making significant investments to make VoLTE work. A large number of planned roll-outs are a testimony of the same.
