While we are at it, we might as well study a thing or two about Voice over LTE (VOLTE). After all, RCS and VOLTE are said to be the major game changers in the coming generation of telecommunication. VOLTE is an all-IP mobile-access technology with the promise of high bandwidth and low latency. VOLTE is a subset of the IMS technology that is discussed time and again in the book. LTE is not just a concept anymore with commercial LTE network setups at many places and huge investments. There already is mass interest in VOLTE from telecom operators, equipment manufacturers, and even GSMA.

Combination of WebRTC, VOLTE, and RCS

This combo has the potential to completely revolutionize the way we see communication today. It provides the environment for innovative service creation while adhering to open standards. An architectural depiction of these technologies working together is shown in the following diagram:
