The increasing voice over Wi-Fi (VoWiFi) hotspot coverage is fueling the requirement for VoWiFi across the world. During the last couple of years, the governments of several countries have made huge investments in the deployment of Wi-Fi hotspots in various public places. According to reports, there were 124 million community and wireless local area network (WLAN) hotspots all over the world in 2017. This number is predicted to rise to 550 million by 2022.

Numerous factors such as free access to community Wi-Fi hotspots, Wi-Fi, and high speed and capacity Wi-Fi are massively propelling the demand for VoWiFi. The advent of voice over Wi-Fi services has caused major improvements in the quality of service (QoS). This is because VoWiFi allows people to remain connected with each other over call, even in the absence of mobile signal. It also allows people to receive and make calls reliable without upgrading their smartphones or installing additional applications.

Furthermore, this technology uses the already-existing subscriber identification module (SIM) security mechanism for protecting and authenticating communications. In addition to this, it offers a seamless network transfer during a call. The availability of this technology at affordable prices and the lack of proper network coverage at various indoor establishments such as offices, shops, and homes are causing the rapid expansion of the various VoWiFi services providing companies around the world.

The aforementioned factors are driving the advancement of the global VoWiFi market. The valuation of the market is predicted to grow from $2,035.3 million in 2019 to $22,801.2 million by 2030. Furthermore, the market is predicted to advance at a CAGR of 24.5% between 2020 and 2030. Circuit-switched fallback (CSFB), voice over IP multimedia subsystem (IMS), and voice over LTE generic access (VoLGA) are the most widely used VoWiFi technologies.

Depending on end user, the VoWiFi market is categorized into commercial and residential. Of these, the residential category recorded higher growth in the market in the past years. This was because of the various benefits offered by the VoWiFi technology including uninterrupted call services, even in the places that do not have proper cellular network. The commercial category is predicted to register faster growth in the market in the forthcoming years.

This will be because of the rapidly rising Wi-Fi network coverage at various public places, industrial parks, offices, and other locations. Globally, the VoWiFi market will demonstrate the fastest growth in Asia-Pacific (APAC) in the future, as per the estimates of P&S Intelligence, a market research company based in India. In this region, China is home to the biggest VoLTE subscriber pool, due to the existence of several major telecom operators such as China Mobile, China Unicom, and China Telecom.

Hence, it is safe to say that the demand for VoWiFi will surge all over the world in the future years, due to the rising VoWiFi network coverage in several countries and the growing demand for better connectivity and cellular networks.
