Essentially, GAN allows cellular communication packets to be forwarded to a network access point over the internet, rather than over-the-air using cellular networks. It extends mobile voice and data applications over Internet Protocol networks to enable communication over the internet, bypassing cellular networks altogether. Wi-Fi calling is based on a protocol called GAN, or Generic Access Network. It is also different from VoWLAN, which is essentially VoIP over a Wi-Fi network. While VoWiFi is somewhat similar to VoIP (Voice over Internet Protocol) in some aspects, they differ in some critical areas insofar as their implementations are concerned. However, instead of using the carrier’s cellular network to place the call, VoWiFi uses a local Wi-Fi hotspot for the task. The authentication, call connection, call routing all work as a regular call, as the technology is essentially the same as VoLTE. Another requirement for Wi-Fi calling is a VoLTE-enabled device, which has become commonplace since the advent of 4G several years ago.Īs a user, Wi-Fi calling is almost identical to making a regular phone call without using a third-party app. ![]() As long as there’s a Wi-Fi hotspot that the phone can latch on to, you can make calls to a mobile phone or a landline number. That could mean using a Wi-Fi connection at home or any other Wi-Fi hotspot accessible when you are out and about, such as at a cafe or library.Īlso known as Voice over Wi-Fi (VoWIFi), the protocol enables users to make and receive voice calls even without cellular reception. It relies on IP networks to connect phone calls over the internet instead of the cell tower. How to Enable Wi-Fi Calling on iPhone and AndroidĪs the name tells, Wi-Fi calling is a feature that enables users to make phone calls using Wi-Fi instead of a cellular connection.
