Motorola Supports Open Mobile Alliance's Push-to-Talk Over Cellular Standard with New Handsets & Services

Company to deliver full range of OMA-compliant PoC solutions to promote increased interoperability and adoption worldwide

LIBERTYVILLE, Ill., July 17 / Motorola, Inc. (NYSE:MOT) today announced that it will support the new Push-to-Talk over Cellular (PoC) standard recently released by the Open Mobile Alliance (OMA) -- PoC 1.0 and XDM 1.0 -- on its PoC-capable device portfolio and network solutions. By implementing these new OMA PoC enablers, Motorola will be able to offer more open and interoperable end-to-end PoC solutions to operator customers, provide consumers with an even greater seamless experience, and help drive overall PoC adoption worldwide.

The new OMA PoC enablers will offer a variety of benefits to users of compliant handsets and services. OMA PoC 1.0, a multi-party form of immediate communication, allows mobile phone users to engage in walkie-talkie style one- to-one and group conversations. OMA PoC 1.0 cooperates mainly with two other Enabler Release specifications -- OMA XDM Document Management Enabler 1.0 (OMA XDM 1.0) and OMA Presence Enabler 1.0. These enablers give users the ability to group communities of friends or colleagues for one-to-one and one-to-many conversations, and also to see their presence for availability. The presence feature, which Motorola will also support when it becomes ratified, allows end users to reflect their availability and preferred mode of interaction.

Motorola's many PoC-capable handsets currently deployed across markets worldwide -- such as the super-thin SLVR -- are designed to be forward compatible and support the OMA feature for carriers that utilize the Motorola server solution. In addition, Motorola will begin to deliver new OMA PoC compliant devices that will support the PoC, XDM and presence features and will work seamlessly with all OMA PoC network implementations.

"The OMA standard ratification marks the beginning of a new chapter in the evolution of push-to-talk over cellular by giving consumers the ability to 'push-to' friends, family and colleagues regardless of which carrier they subscribe to," said Peter Neary, Director, Global PoC Handsets, Motorola Mobile Devices. "This kind of access was key to driving the success of SMS over the last few years and we believe it will do the same for PoC. As a leader in PoC solutions and a key contributor to the OMA test specification, we're excited to be at the forefront of driving PoC adoption through greater interoperability."

Motorola played an integral role in defining the technical enabler test specifications for the OMA PoC standards -- in addition to taking a lead position in defining the OMA Test Fest environments and networking configuration requirements. "Adopting the new OMA standards is a continuation of Motorola's commitment to open standards and to our customers," added Neary.
