VICTORIA and CHICAGO – Canadian wireless manufacturer VCom, along with several other companies, will show a live demonstration of an IP voice over WiMAX call at next week’s GLOBALCOMM conference in Chicago.
VCom, CableMatrix Technologies, AudioCodes, and Emergent Networks, have teamed up for the demonstration. "The combined elements enable high quality IP voice over the IEEE 802.16 air interface standard by incorporating dynamic QoS on behalf of authorized IP voice sessions," says their joint press release.
The demonstration illustrates a completely deployable SIP based voice solution for broadband wireless service providers. QoS is triggered and admitted in real-time by Emergent’s Session Border Controller (SBC) and CableMatrix’s Policy Decision Function (PDF) when a call’s initiated by the AudioCodes’ Analog Terminal Adapter (ATA). VCom’s VistaMAX base station allocates the necessary QoS based upon characteristics of the admitted IP voice call. Calls are then terminated off network by AudioCodes’ core media gateway. Service quality is maintained throughout the duration of the call even when competing against bandwidth intensive video sessions.
"Our demonstration shows how wireless broadband operators can effectively manage the high-bandwidth demands of media-rich IP applications such as voice and video," said Jay Malin, vice-president of business development at CableMatrix. "Together with VCom, AudioCodes and Emergent, we developed a complete solution that, by efficiently managing bandwidth resources, creates new revenue generating opportunities for the operator."
Focusing on standards based technology; the solution demonstrates the viability of differentiated services in an IP network. Components used in the demo are compatible with the emerging WiMAX standard for interoperability and with the IP Multimedia Subsystem (IMS) framework used for next-generation converged IP services.
"IP voice over WiMAX provides wireless broadband service operators an extremely cost-effective solution to bundle high-quality voice communication with data services," said Richard Blenkinsop, vice-president of business development at VCom. "Through integrating our technologies, we provide operators the ability to reserve bandwidth resources that guarantee end-to-end call quality."
