Voice over LTE Market Size, Share & Trends Analysis Report By Application, By Technology, Regional Outlook, Competitive Strategies, And Segment Forecasts, 2019 To 2025

Increased spectrum efficiency is expected to drive the global Voice over LTE market over the forecast period. Voice over LTE (VoLTE) is a technology, which enables voice calls over an LTE network. It sends voice calls over IP-based LTE networks and harnesses data capabilities of LTE with traditional voice services on to the same LTE network. The technology enables both voice and data to merge thereby resulting in better efficiency as well as quality. It also helps to send voice calls over IP-based LTE networks, thereby harnessing the data capabilities of LTE.

The technology empowers network operators to provide rich video, messaging, and voice services. It also enables the operators to use data network for transmitting voice services in small sized packets and increase spectrum efficiency, thereby reducing maintenance as well as operational costs. The technology also allows the operators to utilize their IMS infrastructure, optimize the spectrum efficiency, thereby adding value to the existing voice plans. The technology allows operators to offer a new set of standards based on services such as Rich Communication Services (RCS). RCS includes video, voice mail, real time language translation, instant messaging, and video calling. The rich communication services reduce the time to connect VoLTE calls and also improve battery life over other VoIP applications.

Rapid call set up time due to reduced latency and decrease in maintenance as well as operational costs is expected to drive VoLTE market growth. Rising adoption of VoLTE services by operators is expected to fuel Voice over LTE market growth over the forecast period. Lesser availability of VoLTE enabled devices coupled with lack of carrier inter-operability is expected to inhibit the VoLTE market. The technology offers provisions for faster call setup times, RCS, true device interoperability, and High Definition (HD) voice. HD voice gives a very clear audio output and also scrapes off the background noise much better than standard voice calls.

The technology makes use of IMS call control for LTE voice services. IMS offers voice services such as calling line identification, terminating or call originating, and services such as advanced multimedia and value added services. The technology is expected to be favorable for subscribers as well as mobile network operators. Reuse of 2G & 3G spectrum reduces the requirement for a new spectrum. Additionally, simplification of service delivery and optimization of network helps in cost reduction.

One of the key VoLTE market trends is telecom operators regaining control over the VoIP market, previously dominated by OTT VoIP applications. The telecom industry is expected to witness a spur in data-driven services, which require better coverage, greater speed, and higher bandwidth over the forecast period.

The VoLTE market can be segmented on the basis of technology which includes Voice over IP Multimedia Subsystem (VoIMS), Circuit Switched Fallback, and Dual Radio or Simultaneous Voice and LTE (SVLTE).

In terms of revenue, developed countries are shifting towards the LTE coverage, wherein VoLTE is expected to become an integral part of the network architecture. Furthermore, a shift towards, network strategy is anticipated over the forecast period thereby requiring interoperability, and network capacity.

Key market players include Nokia Solutions & Networks Huawei Technologies Co. Ltd., AT&T Inc, Alcatel-Lucent, Ericsson, Metro PCS, LG Uplus, Verizon Wireless, SK Telecom, and KT Corporation. Nokia VoLTE core, including IMS /TAS and SDM, is a provider of next generation voice and messaging service. Furthermore, VoWiFi & fixed IP enhance the customer experience, thereby enabling the operators to bundle the services together. Voice over Wi-Fi & WebRTC uses the same IMS core as VoLTE, thereby enabling the transmission and reception of multimedia as well as communication services. Additionally, by providing this technology, operators enhance indoor coverage with the help of Wi-Fi and extend communication services with WebRTC.
