Voice over Wi-Fi (VoWiFi) Market

Global Voice over Wi-Fi (VoWiFi) Market Size

The global Voice over Wi-Fi (VoWiFi) market was worth USD 8.75 billion in 2025. The global market size is projected to reach USD 10.89 billion in 2026 and USD 62.88 billion by 2034, growing at a CAGR of 24.5% from 2026 to 2034.

As people get used to Wi-Fi technology more and more, mobile operators (Telcos) aim to exploit these potential business opportunities by offering VoWiFi to residents and businesses, and they plan to expand the area of coverage of their service by setting up faster broadband connections. VoLTE is analogous to Voice over Internet Protocol (VoIP) service and supports voice calls over a broadband connection using Internet voice applications such as Skype and Vonage. These services offer three times more voice and data capacity than 3G UMTS and up to six times more than GSM 2G.

Voice over Wi-Fi (VoWiFi) uses a Wi-Fi network for voice services. In most cases, the Wi-Fi network and the voice components that support the voice system are the private property of the end users. These voice-over services allow mobile network operators to offer full voice, video, and messaging services. These services transmit voice in small data packets, thereby reducing congestion, increasing spectrum efficiency, reducing operating and maintenance costs, and supporting instant messaging and language translation in real time. VoWiFi services are available to smartphone and tablet customers using OTT (over-the-top) services. As VoLTE consolidates, network device OEMs are strategizing to implement an increasing number of VoIP clients complementary to Wi-Fi on the terminal chipset. This integrated client will allow the complementary use of VoLTE and VoWiFi technologies to make voice calls with just one click.

MARKET DRIVERS

Increasing Investments and Availability of High-Speed Broadband Connections

The increasing investments by leading players and the availability of high-speed broadband connections will likely propel the growth of the global voice-over Wi-Fi market in the coming years. Potential downsides expected to slow the growth of the global VoWiFi market include the need for a transmitter and receiver (i.e., communication devices) that support this technology. For instance, in India, the government aims to install 10 million Wi-Fi access points by 2022 to facilitate public data offices. It has established five access points for public services in each of the 250,000-gram panchayats or village blocks. BSNL has installed 25,000 Wi-Fi access points as part of a government program, which it intends to complete by the end of the current fiscal year in 2019, which could increase the VoWiFi market. Increasing the number of Wi-Fi access points can also help operators free up their spectrum, as users can use Wi-Fi access points to make a call instead of using the operator's network. Thus, operators can save their investments.

Public Wi-Fi hotspots are gaining popularity and is a notable trend in the global market. A general access network allows users to continue having access to make calls without needing a nearby cell tower. In addition to covering places with poor cellular reception, the existence of public Wi-Fi access points requires more VoWiFi. This further encourages users to use public Wi-Fi, especially in remote areas, where mobile networks are worse than in urban areas. Operators are likely to take advantage of the availability of Wi-Fi to use VoWiFi and extend coverage, especially indoors and in areas with poor cellular coverage, to reduce the churn rate, which could enhance market growth. In the future.

MARKET RESTRAINTS

Dependence on Stable and High-Speed Wi-Fi Networks

Despite tremendous expansion, the Global Voice over Wi-Fi (VoWiFi) industry has its share of challenges and restrictions. One key drawback is the dependence on stable and high-speed Wi-Fi networks. The smooth operation of VoWiFi services relies heavily on the availability of strong and consistent wireless connectivity, in regions or areas with inadequate Wi-Fi infrastructure or areas prone to frequent signal disruptions, the quality of VoWiFi calls may be compromised, hindering user experience.

SEGMENTAL ANALYSIS

By Technology Insights

VoLTE or voice over LTE is expected to represent a significant share, as the technology segment requires a higher bandwidth allocation than its peer technologies.

REGIONAL ANALYSIS

The global Voice over Wi-Fi (VoWiFi) market is growing in the Asia-Pacific, Europe, North America, South America, and the Middle East and Africa regions. North America has a significant market share as a result of the region's growing number of Wi-Fi users with each passing year and the early adoption of the IP Multimedia Subsystem (IMS).

KEY PARTICIPENTS IN THE MARKET

The leading players in the global VoWiFi market are Huawei Technologies Co. Ltd., Nokia Solutions and Networks, Verizon Wireless (Verizon Communications), Ericsson, Aptilo Networks, Alcatel-Lucent SA, LG Uplus Corporation, MetroPCS Communications, Inc., AT&T, Inc., KT Corporation and Mitel Networks Corporation.

RECENT HAPPENINGS IN THE MARKET

• In May 2019, Cellcom, a nationwide communications service provider in Michigan and Wisconsin, selected Mavenir to implement its virtualized IMS mobile base software and voice-over WiFi (VoWiFi) solutions. This virtualized technology permits operators to quickly and easily create and manage telecom-grade services based on a wide range of commercially available hardware.

• In February 2020, Telefónica UK Limited contracted with Mavenir Systems Inc. to use the virtualized IMS for VoWiFi in its national data centers. The solution can offer support to mobile services for over eight million customers.

• In February 2018, Eastlink Inc., a Canadian telecommunications operator, selected Ericsson as the primary backbone of VoLTE and Wi-Fi calling. The company’s funding can be the basis for future Wi-Fi calling and 5G services.
