QUALCOMM Demonstrates VoIP Mobility across Multiple Test Environments

TMCnet Contributing Editor
 
QUALCOMM Inc. has successfully demonstrated full mobility of high-capacity VoIP calls across multiple test environments. Calls were tested over mobile, pedestrian and fixed environments, and the results will enable operators to migrate voice services to IP-based platforms as a common service platform.

The field tests involved 62 simultaneous calls and were conducted over CDMA2000 1xEV-DO Rev. A in one sector within a single 1.25 MHz channel, in a fully mobile configuration. The test network showed capacity gains of about 30 times greater than mobile analog voice, and results from a fully loaded commercial network might be somewhat lower.

The company used commercial-ready application specific integrated circuits in handset and prototype networks. The tests validated the quality and capacity of fully mobile VoIP over EV-DO Rev. A and set the pace to accommodate large-scale commercial trials by network operators. VoIP over EV-DO Rev. A leverages the SIP protocol to achieve quality of service over traditional landline voice.


The tests represent a step toward convergence of IP and mobile data services with landline wide area IP networks. QUALCOMM is helping customers expand on the IP Multimedia Subsystem (News - Alert) (IMS) strategies, and proven mobility will enable them to efficiently merge wireline and wireless networks based on IMS, enabling a number of enhanced services.

“Operators globally have committed to the rapid deployment of CDMA2000 EV-DO Rev. A. These tests prove EV-DO Rev. A’s capability for delivering high-capacity, high-quality VoIP over 3G mobile broadband networks,” said Dr. Roberto Padovani, chief technology officer of QUALCOMM.

“QUALCOMM is committed to innovating on the 3G roadmap and will drive the leading edge of airlink enhancements converging onto one IP interface,” said Padovani. “High-capacity, full-mobility VoIP is a significant milestone in this vision for the evolution of mobile broadband networks. It will enable operators to supercharge their service packages by offering customers a rich mix of voice and data, and end users will have a heightened multimedia experience from the resulting real-time audio, video and data streams their service providers offer.”
