If other participants of the receiving group try to send in parallel, the messages will not be forwarded by the server.Īnyone who wants to use Push-to-Talk does not need any special hardware. the server can only forward messages from one sender at a time. Push-to-Talk establishes half-duplex connections, i.e. The voice messages themselves are sent in the so-called Real Time Protocol. Depending on the speed of the network, whether UMTS or LTE, and the reception situation, the voice message arrives with a slight delay. The speech is divided into data packets and sent to a server, which forwards them to the recipients. The transmission works similarly to the “Voice over IP” method. Push-to-talk technology uses the cellular network to transmit voice messages. In the corporate context, however, PPT has become established and has even largely replaced analog radio in some industries. As a result, push-to-talk has not been able to establish itself in the consumer market, at least in Germany. Depending on the software used, various additional functions can be used, for example, voice messages can be saved and listened to again later.Īt its core, the function corresponds to what WhatsApp and other messenger services also do. Messages can be sent not only to individuals, but to groups. There are two options for reception: Either the messages can be heard directly or they are only played when a user selects them via a button. The name describes what Push-to-Talk has to offer: You press a button and can record a voice message, which is then sent via a mobile device. It alludes to the fact that the mobile network (Cellular) is used to transmit voice messages. In some cases, the term push-over cellular, PoC, is used synonymously. It is not new, but has been used in mobile communications for many decades. Push-to-talk, or PPT for short, is a voice radio technology based on mobile networks.
