The voice over Wi-Fi (VoWiFi) market growth will be fueled by a number of factors, such as an exponential rise in the Wi-Fi hotspot availability and substantial enhancements in the overall quality of service (QoS). During the forecast period (2020–2030), the market is projected to witness a 24.5% CAGR. The market generated $2,035.3 million in 2019, and it is expected to reach $22,801.2 million by 2030. At present, the market is witnessing the trend of offloading the mobile data traffic to the Wi-Fi network.

A tremendous rise in the global Wi-Fi hotspot coverage is stimulating the VoWiFi market advance. In recent years, several governments have spent a significant amount on the installation of Wi-Fi hotspots in public areas. The number of community hotspots and wireless local area network (WLAN) hotspots is expected to reach 550 million by 2022, 261 million of which will be in Asia-Pacific (APAC) alone. Thus, the higher capacity and speed of Wi-Fi, free access to Wi-Fi, and large-scale deployment of community hotspots will support the market growth in the coming years.

Moreover, the continuous improvements in the overall QoS since the advent of VoWiFi services will drive the VoWiFi market during the forecast period. This technology allows customers to remain connected over the call even without a mobile signal. It enables users to reliably receive and make calls without upgrading the smartphone or installing any additional app. Moreover, the VoWiFi technology utilizes the existing security mechanism of the subscriber identification module (SIM) to protect and authenticate communications. It also provides a smooth transfer of the network from the Wi-Fi to the cellular network, while the call is going on.

Geographically, North America accounted for the largest share in the VoWiFi market in 2019 due to the presence of a large number of users in the U.S. and high average revenue per user (ARPU) in the country. Moreover, the existence of key telecommunications companies in the nation, such as Sprint Corporation, Verizon Wireless, AT&T Inc., and T-Mobile USA Inc., will support the market growth in the forecast years. These regional players are focusing on partnership with leading players to provide enhanced services and products to their customers.

Furthermore, the Asia-Pacific (APAC) VoWiFi market is projected to demonstrate the fastest growth and become the largest market during the forecast period. China, Japan, and South Korea are among the early users of the VoWiFi technology, wherein Japan and South Korea also observe the highest penetration of the VoLTE technology. China has the largest number of VoLTE subscribers due to the presence of telecom operators such as China Mobile, China Unicom, and China Telecom. These operators are expanding their Wi-Fi network across the country, which is supporting the provision of VoWiFi services.

The VoWiFi market is advancing toward a fragmented stage due to the presence of several players like Verizon Wireless, T-Mobile USA Inc., China Mobile Limited, Vodafone Group Plc., and AT&T Inc. These companies are launching new services to expand their geographical presence. For example, Telefónica UK Limited, in February 2020, signed a deal with Mavenir Systems Inc., wherein the former will use the latter’s virtualized IMS for VoWiFi and VoLTE in the U.K.’s nationwide data center infrastructure. This solution will offer mobile service support to more than 8 million customers.

Thus, the increasing network congestion and surging number of community and public Wi-Fi hotspots will fuel market growth in the forecast period.
