WifiCast is an application that lets you communicate in a way similar to the walkie-talkies using different devices connected to the same wifi network. To do this, it uses multicast data transmission mechanism designed to send information flows from a sender to multiple receivers without the number of receptors influencing the network traffic.
WifiCast, by default, starts in listening mode. This allows us to listen to what someone else transmits. To speak simply click once on the button that says “Listening” and see that it will indicate “Speaking.”
You can download the app WifiCast from Google Play and from the App Store.
