How Does Push to Talk Work?
Overview and History Push to Talk, often abbreviated as PTT, refers to any two-way communication where a user has to push a button to talk, and then release it to listen to the other party. In modern usage, it refers to a feature on mobile phones that allows users to simulate a two-way radio communication. Cellular Push to Talk also allows groups of people to establish a simulated radio dispatch between all members of the predetermined group without making everyone call in. Cellular Push to Talk came to be when Nextel Communications, named FleetCall at the time, began purchasing specialized mobile radio frequencies across the country. These frequencies were primarily used for truck and cab dispatch, but as the technology grew, it allowed the cells to “speak” to each other and enabled the growth of the network beyond just a small region. When Nextel grew into a nationwide carrier, it kept part of its radio past in the form of Push to Talk over its network. Functionality Push to Talk est
