The ability to make calls without cellular network is not impossible and now Huawei has made it possible in India. The Chinese smartphone manufacturer launched its Voice over WiFi (VoWiFi) calling support for its smartphones. The VoWiFi service, which is also called Wi-Fi Calling, enables users to voice call or video call other VoWiFi supported smartphones when a Wi-Fi connection is available. The users can even make VoWiFi call in airplane mode, and even when cellular network is not available.
The Huawei VoWiFi solution complies with most specifications and common subscribers can access IMS networks. This uses Wi-Fi hotspots and use HD voice and video services. The Huawei VoWiFi solution covers cellular telecommunications technologies. This includes radio access, core network and service capabilities, which provide a complete system description for mobile telecommunications. The 3GPP specifications also provide hooks for non-radio access to the core network, and for interworking with non-3GPP networks.
VoWiFi immensely benefits subscribers who often suffer from network issues at their home or workplace. It will also help operators to develop new business, ensure that users stick around and enhance competitiveness of voice solutions. Subscribers can access network under Wi-Fi hotspots, and enjoy HD voice and video service and a smooth handover between VoLTE and VoWiFi.
VoWiFi greatly improves indoor coverage, decreases cost of MVNO, provides cost efficient roaming solution, and increases carrier competitiveness. This solution can solve the problem of indoor coverage network construction. VoWiFi solution support international roaming call. VoWiFi users can access any Wi-Fi.
