WiFi calling, also known as Voice over WiFi (VoWiFi), is a feature that allows users to make phone calls using a WiFi network instead of traditional cellular networks. This feature has gained popularity in recent years, especially among users who experience poor cellular coverage in their homes or offices. In this article, we will explore the availability of WiFi calling on Android devices, its benefits, and how to enable it.
What is WiFi Calling?
WiFi calling is a technology that enables users to make voice calls using a WiFi network. It works by converting voice calls into digital data, which is then transmitted over the internet using a WiFi connection. This technology is also known as Voice over Internet Protocol (VoIP). WiFi calling is different from traditional cellular calling, which uses cellular networks to connect calls.
How Does WiFi Calling Work?
WiFi calling works by using a combination of technologies, including:
- Session Initiation Protocol (SIP): This protocol is used to establish and manage voice calls over the internet.
- Real-time Transport Protocol (RTP): This protocol is used to transmit audio data in real-time.
- WiFi network: This is the network used to connect to the internet and transmit voice calls.
When a user makes a WiFi call, their device converts the voice call into digital data and sends it to the nearest WiFi access point. The access point then forwards the data to the internet, where it is routed to the recipient’s device. The recipient’s device then converts the digital data back into a voice call, allowing the user to communicate with the caller.
