세계의 VoLTE 시장 보고서 : 기술별, 디바이스 유형별, 최종 이용 산업별, 지역별(2025-2033년)

The global voice over LTE (VoLTE) market size reached USD 23.2 Billion in 2024. Looking forward, IMARC Group expects the market to reach USD 919.8 Billion by 2033, exhibiting a growth rate (CAGR) of 50.5% during 2025-2033. The growing penetration of Internet of Things (IoT) devices and applications requiring low-power, and low-latency communication capabilities, the escalating consumer expectations for high-quality voice services, and continual technological advancements are some of the major factors propelling the market.

Voice over LTE (VoLTE) is a communication standard that allows for the transmission of voice and multimedia content over 4G Long-Term Evolution (LTE) networks, an improvement over the traditional 2G or 3G networks. Unlike previous generation networks, VoLTE delivers high-quality, crisp voice calls and enables simultaneous use of voice and data. It works by converting the voice into a digital signal, which is transmitted over the LTE network, facilitating rapid data transfer and high-definition voice calls. This digital transformation also paves the way for additional services such as video calling, file sharing, or live streaming. Furthermore, it supports a greater call capacity than its predecessors, contributing to its efficiency.

The proliferation of Internet of Things (IoT) devices and applications majorly drives the global market. IoT devices often require low-power, low-latency communication capabilities, making VoLTE a suitable choice for supporting these applications. Along with this, VoLTE offers distinct advantages for roaming and international calls, making it an attractive choice for travelers and international businesses. With traditional roaming, calls are usually routed through legacy networks, leading to reduced call quality and higher costs. In addition, consumer expectations for high-quality voice services have grown significantly over the years. Traditional circuit-switched voice calls, while reliable, often lack the clarity and richness that users now expect from their communication experiences. VoLTE, with its HD voice quality and reduced background noise, addresses this demand for superior voice communication. Moreover, Rich Communication Services (RCS) represent the next evolution of messaging and aim to provide a more interactive and feature-rich messaging experience compared to traditional SMS. RCS includes features, such as read receipts, file sharing, group chats, and video calling, creating a positive market outlook.

VoLTE Market Trends/Drivers:

Rising Smartphone Penetration

The increasing penetration of smartphones globally is another vital market driver for VoLTE. Smartphones have become an indispensable part of modern life, and their affordability and widespread availability have led to a rise in adoption across different demographic segments. As a result, a larger portion of the population now possesses VoLTE-capable devices. VoLTE requires compatible devices that support Voice over LTE technology, which can utilize the IP-based network for voice calls. As smartphone ownership rises, the potential customer base for VoLTE services expands significantly. Mobile network operators and service providers recognize this trend and are increasingly investing in VoLTE infrastructure to leverage the growing smartphone user base.

Growing Demand for Enhanced Communication Services

With the increasing reliance on digital communication and the need for efficient and reliable voice services, there is a growing demand for enhanced communication solutions. VoLTE offers several features and benefits that cater to this demand, such as HD voice quality, faster call setup, and seamless handovers between 4G and 5G networks. Moreover, VoLTE enables the integration of voice and data services, enabling users to access the internet, use applications, and make voice calls simultaneously without any compromise in quality. This enhanced user experience is driving the demand for VoLTE, especially in industries that heavily rely on real-time communication, such as healthcare, emergency services, and business communications.

Expanding 4G and 5G Networks

One of the key market drivers for the Voice over LTE (VoLTE) industry is the continuous expansion of 4G and 5G networks worldwide. As more countries upgrade their infrastructure to support higher data speeds and improved network efficiency, the demand for VoLTE services rises. 4G networks have already become widespread, and 5G networks are rapidly rolling out, promising even faster data speeds, lower latency, and higher capacity. In addition, the proliferation of these advanced networks creates a conducive environment for VoLTE adoption. VoLTE offers significant advantages over traditional circuit-switched voice calls, such as higher call quality, faster call setup times, and concurrent voice and data usage. As consumers experience the benefits of VoLTE on these modern networks, the demand for compatible devices and services grows, driving the VoLTE market forward.

VoLTE Industry Segmentation:

Breakup by Technology:

• 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)
• Single Radio Voice Call Continuity (SRVCC)

The adoption of circuit switched fall back (CSFB) in the voice over LTE (VoLTE) industry is primarily driven by the need to maintain voice services for devices that do not yet support VoLTE. As VoLTE technology becomes prevalent, not all devices in the market are equipped to handle VoLTE calls. CSFB acts as a bridge between these legacy devices and the LTE network by facilitating a smooth transition to circuit-switched networks (2G/3G) when initiating or receiving voice calls. This seamless handover ensures that users with non-VoLTE compatible devices can still access reliable voice services without any disruptions.

On the contrary, single radio voice call continuity (SRVCC) in the voice over LTE (VoLTE) industry stem from the increasing demand for seamless voice services during the transition from LTE to legacy 2G/3G networks. SRVCC addresses this need by ensuring uninterrupted voice calls when a user moves out of the LTE coverage area, guaranteeing a smooth handover to 2G/3G networks without call drops or disruptions. This technology becomes particularly crucial as more network operators adopt VoLTE, aiming to enhance voice call quality and free up spectrum for data services.

Breakup by Device Type:
