    Push to talk over Cellular (PoC) is a new still evolving service concept for mobile systems. Traditionally Push to Talk (PTT) service has been used in proprietary networks for decades but recently new Internet Protocol (IP) based specifications for PoC have been introduced. The service has been available in lead markets since 2004 but the mass-market adoption has not yet taken place. Commercialization process of PoC still includes many technical and market risks. The PoC technology has, however, potential to create new mobile service evolution path starting from voice and extending later on to other group applications. This document reviews different strategies related to standardization, system architecture, vendors’ product strategies, substitutes, regulation and service provision relevant for PoC and discusses the various options for mobile operators and vendors how to implement this new service successfully.
