VoLTE
is not just about costs and spectral efficiency. It enables operators to
provide the better voice quality and lower latency that are the key
requirements of GSMA’s rich communication services (RCS), and that will enable
them to support the chat, voice, and video applications envisaged by the
recently launched joyn project. In this context, VoLTE is a necessary complement
to video services and applications that have started to dominate the traffic
load and that promise to generate an increasing portion of revenues.
Today
most operators find these services challenging to provide, as they cannot
consistently guarantee a specific level of performance even to high‐paying
subscribers. VoLTE, coupled with QoS, traffic prioritization, and policy, will
enable operators to roll out the adaptive multi‐rate wideband (AMR‐WB) codec
needed for high‐definition (HD) voice, differentiate the services they offer
across subscriber segments (high‐paying, high‐performance subscribers versus
best‐efforts, lower‐ARPU subscribers), and from the services offered by their
competitors. The increased variety and richness of voice services that VoLTE
will allow drives the expectation shared by 50% of operators that, despite the
worries of competition from OTT players like Skype or Viber and despite the
elusiveness of their monetization efforts, VoLTE will lead to higher revenues
and better subscriber experience. READ THE WHITE Below for further insights.
