This is where WiFi calling comes into play, promising to revolutionize mobile communication by leveraging the power of internet connectivity. But does WiFi calling truly improve call quality?
Understanding WiFi Calling
WiFi calling, also known as Voice over WiFi (VoWiFi), is a technology that allows users to make voice calls over a WiFi network instead of a traditional cellular network. This means that as long as you have a stable internet connection, you can make calls from anywhere in the world, without relying on cellular coverage. WiFi calling uses the internet protocol (IP) to transmit voice data, which is then converted into a traditional voice signal at the receiving end.
How WiFi Calling Works
The process of making a WiFi call is relatively straightforward. Here’s a step-by-step explanation:
- Your smartphone connects to a WiFi network, which provides an internet connection.
- When you make a call, your phone converts your voice into digital data and sends it over the internet to the recipient’s phone.
- The recipient’s phone receives the digital data and converts it back into a voice signal, allowing them to hear your voice.
- The process is reversed when the recipient responds, and their voice is transmitted back to your phone over the internet.
The Benefits of WiFi Calling
WiFi calling offers several benefits over traditional cellular calling, including:
