How can you profit from VoWi-Fi?

Wi-Fi is everywhere. According to a recent study by Wi-Fi Alliance as much as 71% of all mobile communication flows over Wi-Fi. So let’s discuss the benefits of VoWi-Fi.


VoWi-Fi stands for Voice over (EPC-integrated) Wi-Fi and it uses a wireless broadband network for the purpose of vocal conversation. VoWi-Fi is a complementary technology to VoLTE and utilises IMS technology to provide a packet voice service that is delivered over IP via a Wi-Fi network.
