Push-To-Talk (PTT)(VoLTE), is a service option for a cellular phone network that enables subscribers to use their phones as walkie-talkies with unlimited range. A typical push-to-talk connection connects almost instantly. A significant advantage of PTT is the ability for a single person to reach an active talk group with a single button press; users don't need to make several telephone calls to coordinate with a group.
Push-To-Talk VoLTE similarly provide half-duplex communications — while one person transmits, the other(s) receive. This combines the operational advantages of PTT with the interference resistance and other virtues of mobile phones. The operation of phones used in this way is similar to Walkie-Talkie use.
