VOICE OVER LTE (VoLTE) MARKET REPORT OVERVIEW

The global voice over LTE (VoLTE) market size was USD 74.92 billion in 2024 and the market is projected to touch USD 2659.5 billion by 2032, exhibiting a CAGR of 66.51% during the forecast period.

Voice over LTE (VoLTE) changes how voice calls use the 4G LTE network. It converts voice in the same way it does any other kind of data into packets. VoLTE works under the wider IP Multimedia Subsystem (IMS). This system combines voice and multimedia as data streams over an IP interface. This integration means that both voice and data can be processed at the same time which is an improvement from the earlier way of processing as distinct circuit-switched networks. Technology such as VoLTE has improved the quality of voice, background noise and clarity, especially in harsh environmental conditions. It also supports faster call setup times and more efficient utilization of the spectrum as compared to previous technologies.

In addition to voice improvements, VoLTE allows for the use of data services such as browsing while on a call and increasing face time. They also lead to longer battery life than the traditional VoIP options and this makes it the most suitable for mobile use. Currently, VoLTE is already live with 262 operators in 120 countries using the technology and 194 companies launching VoLTE-HD voice services. Currently, all modern smartphones support VoLTE, which increases the availability and demand for it in consumer terms.

VOICE OVER LTE (VoLTE) MARKET SEGMENTATION

By Type

Based on type the global market can be categorized into Voice Over IP Multimedia Subsystem (VoIMS), Circuit Switched Fall Back (CSFB), Dual Radio/Simultaneous Voice and LTE (SVLTE), Voice Over LTE Via Generic Access Network (VOLGA) and Single Radio Voice Call Continuity (SRVCC).

• Voice Over IP Multimedia Subsystem (VoIMS): VoIMS is the primary innovation on which VoLTE is based to support voice and multimedia services over IP networks. It specifies the means of controlling and defining how voice and multimedia sessions will be set up. VoIMS does not send the voice calls through the circuit-switched domains but rather through the LTE IP domain thereby being clearer and able to set up faster and be able to support simultaneous voice and data.
• Circuit Switched Fall Back (CSFB): VoLTE is a voice over LTE that is used in communication, CSFB on the other hand is a fallback mechanism. CSFB, on the other hand, provides a way for the VoLTE-enabled device to switch thereby transferring the ongoing voice call to the LTE CSFB-enabled legacy 3G or 2G CS network. This guarantees the voice call continuity despite the lack of the LTE connectivity guaranteeing a different quality and feature set though not as good as the native VoLTE.
• Dual Radio/Simultaneous Voice and LTE (SVLTE): SVLTE is useful for a device to establish voice and LTE data connection at the same time by using two different radio transceivers. This is the latitude for the device to stay on the LTE for data and also integral CS calls at the same time. SVLTE is used to bridge the gap between the lookout for full VoLTE implementation.
• Voice Over LTE Via Generic Access Network (VOLGA): VOLGA can be classified as an alternative approach in voice services to be supported over LTE networks. The device relies on the Generic Access Network (GAN) for the transmission of voice, which is passed via an IP network without the necessity of the IMS support. But for VOLGA, it is rated to offer the VoIP such as communication without the complete VoLTE integration even though it will not be as effective as the VoLTE system.
• Single Radio Voice Call Continuity (SRVCC): SRVCC is defined as the process that allows the handover of a current voice call from LTE to one of the prior modes of CSNs which are the 3G or 2G networks. It enables the voice call to continue when the device is out of the LTE area by converting the call to the circuit-switched domain. The SRVCC is very important in VoLTE so the voice service should be continued during and after the data service where SRVCC plays an important role.

By Downstream Industry

Based on downstream industry the global market can be categorized into Wireless Communication, Mobile Phones, Data Terminals and Others.

• Wireless Communication: The wireless communication segment in the VoLTE market targets those solutions that offer voice over LTE to enhance the experience of the users.
