Ericsson, Motorola, and Siemens announced the first joint interoperability tests for Push-to-Talk over Cellular (PoC). The tests are designed to help provide network operators with easy integration, interoperability and a competitive environment in which to deploy commercial PoC service.
Already in use in North America, PoC is expected to expand in Europe and in Asia - but interoperability is a key factor to such broad-based acceptance. Push-to-Talk over Cellular is similar to a walkie-talkie experience; it is a means of quick one-to-one or group communication. Instead of dialing a number to start a conversation, with one push of a button you simply go to a "buddy list" and select the person you want to contact. Push the button again, talk, and your voice is heard by the recipient.
You can also create group calls so everyone on your buddy list can hear your message simultaneously - just as in a telephone conference. Instead of having to SMS or call each recipient individually, a push of the key is all it takes to send a message directly to an entire circle of friends or work colleagues, for example.
The first technical standard specification for Push-to-Talk - PoC Phase One - was submitted to the Open Mobile Alliance (OMA) in August 2003. Ericsson, Motorola, Siemens and Sony Ericsson are promoting a final version of the PoC standard through the OMA.
The PoC Phase One Specification was developed by wireless vendors to ensure an interoperable Push-to-Talk solution over standard cellular networks.
