The increasing Wi-Fi hotspot coverage all over the world is pushing up the demand for voice over Wi-Fi across the globe. During the last two years, the governments of several countries have made huge investments in the establishment of Wi-Fi hotspots in public places. As per many reports, there were as many as 124 million public community and wireless local area network (WLAN) hotspots around the world in 2017. Moreover, this number will grow to 550 million by 2022.

Numerous factors such as free access to community Wi-Fi hotspots, Wi-Fi (promoting other services), and greater speeds and capacities of Wi-Fi are pushing up the popularity of VoWiFi (voice over Wi-Fi) across the globe. The emergence of voice over Wi-Fi is fueling rapid improvements in the overall quality of service (QoS) for users. This technology allows users to remain connected with each other over the call, even when there is no mobile signal available.

Moreover, this technology allows people to reliably receive and make calls without using any additional application or upgrading the device. It uses the already existing SIM (subscriber identification module) security mechanisms for authenticating and protecting communications. VoWiFi also enables a seamless network transfer from the Wi-Fi to the cellular network, during ongoing calls. The availability of Wi-Fi at affordable prices and poor network coverage at shops, offices, homes, and various indoor places allow mobile operators to massively augment their services.

Due to the aforementioned reasons, the adoption of VoWiFi is growing rapidly all over the globe. This is driving the progress of the global VoWiFi market. As a result, the valuation of the market is predicted to rise from $2,035.3 million in 2019 to $22,801.2 million by 2030. Furthermore, according to the estimates of P&S Intelligence, a market research firm based in India, the market would exhibit a CAGR of 24.5% between 2020 and 2030.

The most widely used VoWiFi technologies are the circuit-switched fallback (CSFB), voice over IP multimedia subsystem (IMS), and voice over LTE generic access (VoLGA). Out of these, the usage of the VoLGA technology is predicted to rise rapidly across the world in the upcoming years. This would be due to the ability of this technology to provide VoLTE services by using the network operator’s 4G infrastructure. Additionally, this technology doesn’t require modifications in the architecture.

Globally, the Asia-Pacific VoWiFi market is predicted to demonstrate the fastest growth in the future. In this region, China currently has the biggest VoLTE subscriber base, due to the existence of major telecom operators such as China Mobile, China Unicom, and China Telecom. The rapid deployment of Wi-Fi networks in other countries is also fueling the advancement of the industry in the region. For example, BSNL, an Indian government-owned telecom company, started a partnership with Google LLC in May 2019.

Thus, it is quite clear that the popularity of VoWiFi would surge all over the world in the upcoming years, mainly because of the increasing deployment of Wi-Fi hotspots in several public places and the growing demand for better Wi-Fi connectivity across the world.
