Voice over Wi-Fi


Voice over Wi-Fi has been proven as a cost effective and simple way to extend service providers voice coverage to smartphones, tablets, laptops, and other personal devices. In places where it might be difficult to provide Mobile Communication QoS, such as in remote urban areas, residential countryside, insulated building or basements as well as locations where there is a need to fully rely on carrier roaming networks, Wi-Fi Calling is the affordable alternative to communicate.

For many years, operators and service providers handled poor voice coverage with Femto-cells, distributed antenna system (DAS), or other costly infrastructure. With Voice over Wi-Fi, providers can solve this problem without expensive solutions while allowing them to enhance their mobility offering.

Extend your Coverage and Attract New Customers

Voice over Wi-Fi (VoWi-Fi), also called Wi-Fi Calling, is a setting on many mobile devices that enables calls to be made and received over a Wi-Fi network rather than over the cellular network. In addition to solving the problem of limited coverage, Calls over Wi-Fi are also affordable and attractive for users at home and travellers in international roaming.
