Software applications on the Android operating system facilitate telephone calls over a Wi-Fi network. This functionality allows users to make and receive calls using a Wi-Fi connection instead of a cellular network. A common example is an application pre-installed on a smartphone or downloaded from a digital distribution platform like Google Play, enabling voice communication via a wireless internet connection.
The capacity to place calls over Wi-Fi presents several advantages, particularly in areas with weak cellular signals but robust Wi-Fi access. It can reduce reliance on cellular data, potentially lowering costs associated with mobile service plans. Furthermore, its integration into mobile operating systems or third-party applications marks a significant development in telecommunications technology, allowing for more flexible and accessible communication options.
