Motorola Debuts IP-based Push-To-Talk Engine for iDEN

Motorola announced an agreement with Nextel Communications to implement Next Generation Dispatch (NGD), a new IP-based Push-To-Talk (PTT) call processing engine. The NGD solution used with Motorola's iDEN technology is designed to replace the call processing system currently used in Nextel's nationwide network.



The NGD development contract includes development of the new IP-based PTT server solution, associated hardware needed to deploy the solution in Nextel's largest markets, plus the development of an All Frame Relay backhaul solution from cell sites to the switching core. NGD will replace legacy PTT call processors, voice duplication equipment and router equipment used in the current architectural design.



The NGD agreement includes the development of technology that will enable Nextel to convert its cell site transport facilities to an All Frame Relay IP based network, which is designed to increase the capacity of existing T1 span lines by reducing Nextel's operating expense. Commercialization is scheduled to commence in the first half of 2006.



Motorola said NGC significantly simplifies the iDEN PTT architecture and extends interoperability for IP-based PTT services on 3G broadband networks that utilize CDMA 1XRTT and EV-DO technology. http://www.motorola.com
