Carriers worldwide are seeking ways to improve the efficiency and capacity of their networks while minimizing costs and improving end-user experience. LTE has served this purpose well in terms of mobile broadband data access, but carriers are struggling to find solutions to fight declining revenues for voice services, the primary stream of revenue for most carriers. Voice over LTE (VoLTE) offers a potential solution. Not only does VoLTE offer unique advantages in lowering a carrier’s voice infrastructure economics, but it also promises to improve voice quality, device battery life and user experience by allowing concurrent voice and data services over a single LTE radio interface.
ARCchart forecasts that the number of devices supporting VoLTE will ramp significantly over the coming years, spurred by aggressive competition against OTT providers. By 2016, we expect a total installed base of over 74 million VoLTE-enabled handsets will be present in the market. However, the OTT mobile VoIP market will also continue to maintain healthy growth.
