The world is rapidly shifting towards a wireless era, and phone calls are no exception. With the advent of WiFi technology, making phone calls has become more convenient and cost-effective. Gone are the days of relying solely on cellular networks to make calls. WiFi calling has revolutionized the way we communicate, providing an alternative to traditional phone calls. But how does it work, and what are the benefits of making phone calls using WiFi?
What is WiFi Calling?
WiFi calling, also known as Voice over WiFi (VoWiFi), is a technology that allows users to make phone calls using a WiFi network. This means that instead of relying on cellular signals, your phone uses a WiFi connection to connect to the internet and make calls. This technology has been around for a few years, but it has gained significant traction in recent times, with many phone manufacturers and carriers embracing it.
How Does WiFi Calling Work?
WiFi calling works by using a combination of your phone’s WiFi antenna and a specialized software to connect to a WiFi network. When you make a call, your phone sends a request to the nearest cellular tower, which then redirects the call to the WiFi network. The call is then routed through the internet to the recipient’s phone, using the WiFi network as a conduit.
The process is enabled by a technology called IP Multimedia Subsystem (IMS), which is a set of standards and protocols that allow for the delivery of multimedia services, including voice, video, and data, over IP networks. IMS enables carriers to offer WiFi calling as a seamless extension of their cellular services, allowing users to make and receive calls, send texts, and access data services over WiFi.
