Ericsson, Motorola, and Siemens Announce Interoperability Tests for Push-to-Talk Over Cellular (PoC) Technology

Strategic Insights -

As the world moves towards more seamless communication experiences, Ericsson, Motorola, and Siemens are leading the charge by announcing the first joint interoperability tests for Push-to-Talk over Cellular (PoC) technology. This groundbreaking collaboration aims to provide network operators with easy integration, interoperability, and a competitive environment to deploy commercial PoC service. With PoC poised for growth in Europe and Asia, interoperability has become a crucial factor for broad-based acceptance.

Key Takeaways:

  • The first joint interoperability tests for PoC technology were conducted by Ericsson, Motorola, and Siemens to ensure seamless communication experiences for consumers.
  • The tests aimed to provide network operators with easy integration, interoperability, and a competitive environment to deploy commercial PoC service.
  • PoC is a means of quick one-to-one or group communication, similar to a walkie-talkie experience, where users can select a "buddy list" and communicate with others by pushing a button.
  • 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 first interoperable products and solutions are expected to be introduced in Q2 2004.
  • Other manufacturers are encouraged to join the interoperability tests to ensure compatibility between devices and PoC servers across vendors.
  • PoC service opens up a whole new realm of voice services for network operators, enhancing telephone service and potentially providing a new source of revenue.
  • PoC service fits a variety of markets, from consumers who want quick communication to small, medium, and large enterprises that need frequent intermediate contacts.
  • The PoC Phase One Specification was developed by leading wireless vendors to ensure interoperable Push-to-Talk solutions over standard cellular networks.
  • The Open Mobile Alliance (OMA) is further enhancing the specification based on wider industry feedback.

Statistics:

  • Sales in 2003 for Motorola: US$27.1 billion.
  • Siemens Information and Communication Mobile Group generated sales of Euro 10 billion with a workforce of 26,900 people in fiscal 2003 (September 30).
  • The Open Mobile Alliance (OMA) has ongoing work in enhancing the PoC Phase One Specification, including the addition of Network-to-Network Interface (NNI) for inter-operator communication.
