At WiMAX World in Boston, Motorola Inc. demonstrated the capability of its Internet Protocol Multimedia Subsystem (IMS) solution to deliver VoIP, end-to-end converged services and applications across today's broadband networks and emerging WiMAX access environments. For example, Motorola's IMS solutions, coupled with WiMAX, will allow operators who do not have last mile access to offer VoIP and IP- Centrex/PBX service for enterprises and residential customers.



Motorola, using its IMS core and MOTOwi4 Canopy solution, demonstrated IP-based voice, video, conferencing services, unified messaging, ringback tones, and other SIP-based applications on multiple devices including Motorola's Ojo Personal Video Phone. "The Motorola IMS solution is a central component of our seamless mobility strategy across multiple access environments including wireless broadband. Our IMS solution supports WiMAX, as well as other packet-based broadband networks like Wi-Fi, DSL and cable, and mobile broadband," said Raghu Rau, senior vice president, Global Marketing and Strategy for Motorola Networks. "This demonstration using Motorola's IMS core for voice and other IP applications is significant because it proves the ability to deliver a full suite of services over MOTOwi4 WiMAX broadband networks."



Motorola is developing a portfolio of MOTOwi4 solutions that includes an end-to-end WiMAX 802.16e access network, IP core, devices and professional services that utilize Motorola's existing businesses and solutions. The architectural design of the MOTOwi4 IP-based systems enable seamless mobility through the IMS core, tying together existing 2G and 3G cellular systems, circuit voice, and higher-tier mobile broadband access services and applications.



The Motorola IMS, designed to be a robust and highly scalable carrier- grade system that enables convergent VoIP across multiple access domains and open interfaces to third-party applications servers, is currently in trial with multiple service providers. Early IMS implementations already are in commercial service being used to deliver Push-To-Talk over Cellular (PoC).
