CANNES, France – February 23, 2004 – Motorola Inc.’s Global Telecom Solutions Sector (GTSS), leveraging its expertise in providing Push-to-Talk over Cellular (PoC) solutions, today announced at 3GSM in Cannes that it has made its standards-based PoC client software available for license to third party GSM/GPRS and UMTS handset manufacturers and software developers. This new PoC Device Interoperability Program extends Motorola’s prior practice of providing its interface specifications, and will help speed the introduction of a wider choice of PoC handsets to market, benefiting both consumers and operators.

"As a company with decades of experience in push-to-talk systems and devices, we enthusiastically support all efforts - through our active engagement in standards development and making our PoC client available," said Murali Aravamudan, vice president and general manager, Winphoria Division of Motorola's GTSS. "We support the harmonization of PoC specifications among all vendors, and have designed our network solutions to be compatible with the standards as they evolve."

Motorola is a leading provider of end-to-end PoC solutions, offering a variety of commercially available PoC handsets, device client software, PoC servers, development and integration support, and interoperability testing.

Motorola’s PoC software client is designed to run on a mobile phone or voice-capable PDA or laptop personal computer, and permits a subscriber to communicate with a quick, one-touch connection to one or many users. It is available to third-party handset manufacturers either directly from Motorola GTSS or through third-party software developers.

These developers will create compatible PoC software customized for the manufacturer’s handsets to provide new high-end capabilities that enable operators to differentiate their PoC offering. The PoC developer’s kit is available with protocol definitions only, or with both the protocol definitions and Motorola’s PoC software client.

Magic4 and Metrowerks are participating in Motorola’s PoC Device Interoperability Program.
