A Robust Push-to-Talk Service for Wireless Mesh Network

Push-to-Talk (PTT) is a useful capability for rapidly deployable wireless mesh networks used by first responders. PTT allows several users to speak with each other while using a single, half-duplex, communication channel, such that only one user speaks at a time while all other users listen.

A Client-Side Design and Implementation for Push to Talk over Cellular Service

This paper proposes a client architecture for the Push to Talk over Cellular (PoC) service based on the Open Mobile Alliance (OMA) PoC specifications v1.0 release. We show that most standard VoIP modules can be reused for the PoC client, and the VoIP software can be easily extended to support PoC service.

IP based Push To Talk on a Mobile Phone

Push-to-talk (PTT) is a new approach to voice communication which emulates walkie-talkie system. The main purpose of this project is to implement PTT on a cellular mobile phone (PoC).

PoC is an instant messaging service like a voice SMS. Instead of dialing, you "push" a button and speak. When you release the button the message is sent. Communication is bidirectional but not simultaneous (half-duplex).
