In today’s digital age, staying connected with friends, family, and colleagues is more important than ever. With the rise of Wi-Fi technology, it’s now possible to make cell phone calls over the internet, eliminating the need for traditional cellular networks. But can you really make cell phone calls on Wi-Fi? In this article, we’ll delve into the world of Wi-Fi calling, exploring its benefits, limitations, and everything in between.
What is Wi-Fi Calling?
Wi-Fi calling, also known as Voice over Wi-Fi (VoWi-Fi), is a technology that allows you to make voice calls over a Wi-Fi network. This means that instead of using your cellular network to make calls, you can use a Wi-Fi connection to connect with others. Wi-Fi calling uses the internet to transmit voice data, making it a popular choice for those with poor cellular reception or those who want to save on their phone bills.
How Does Wi-Fi Calling Work?
Wi-Fi calling works by using a technology called Voice over Internet Protocol (VoIP). VoIP converts your voice into digital data, which is then transmitted over the internet to the recipient’s phone. This process happens in real-time, allowing for seamless communication.
When you make a Wi-Fi call, your phone connects to a nearby Wi-Fi network and establishes a connection with the recipient’s phone. The call is then routed through the internet, using the Wi-Fi network as a bridge between your phone and the recipient’s phone.
