What is WiFi calling and how does it work?
WiFi calling, also known as Voice over WiFi (VoWiFi), is a technology that allows users to make and receive phone calls using a WiFi network instead of a traditional cellular network. This technology uses the internet to route calls, allowing users to stay connected even in areas with poor or no cellular coverage. WiFi calling is especially useful for people who live or work in areas with weak cellular signals, or for those who travel frequently to areas with limited cellular coverage.
WiFi calling works by using a smartphone’s WiFi capabilities to connect to a WiFi network, and then routing calls through that network. This allows users to make and receive calls just like they would on a traditional cellular network, but without the need for a cellular signal. WiFi calling is often used in conjunction with traditional cellular service, allowing users to seamlessly switch between cellular and WiFi networks depending on the strength of the signal.
What are the benefits of WiFi calling?
One of the biggest benefits of WiFi calling is the improved coverage it provides. With WiFi calling, users can make and receive calls in areas where traditional cellular signals are weak or non-existent. This is especially useful for people who live or work in rural areas, or in buildings with thick walls that can block cellular signals. WiFi calling also provides a cost-effective alternative to traditional international roaming fees, as users can make calls over WiFi networks even when traveling abroad.
In addition to improved coverage and cost savings, WiFi calling also provides a higher quality of service. Because WiFi networks are often less congested than cellular networks, calls made over WiFi tend to have better sound quality and fewer dropped calls. This makes WiFi calling an attractive option for businesses and individuals who rely on clear and reliable communication.
Is WiFi calling the same as VoIP?
While WiFi calling and Voice over Internet Protocol (VoIP) share some similarities, they are not the same thing. VoIP is a technology that allows users to make voice calls over the internet using a VoIP phone or computer. VoIP calls are typically made using a dedicated VoIP app or software, and may require a separate account and phone number.
WiFi calling, on the other hand, is a technology that allows users to make traditional voice calls using their smartphone and a WiFi network.
