Qualcomm Demonstrates Fully Mobile VoIP Calls Across A Number of Field Test Environments

Qualcomm Incorporated announced it has successfully demonstrated the full mobility of high-quality, high-capacity voice over Internet protocol (VoIP) calls across multiple test environments, including mobile, pedestrian and fixed, enabling operators to migrate voice services to Internet protocol (IP)-based platforms for a common service platform.

The field tests, which involved 62 simultaneous calls, 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 demonstrated capacity gains approximately 30 times greater than mobile analog voice and results from a fully loaded commercial network could be somewhat lower.

"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.

The full mobility success of these VoIP field tests represent another step toward the convergence of IP and mobile data services with landline wide area IP networks, as Qualcomm helps bring its customers' IP Multimedia Subsystem (IMS) strategies to fruition. Operators will be able to efficiently merge their wireless and wire line networks based on IMS, allowing them to realize unsurpassed cost and operational efficiencies over current deployments. By basing all communications services on an IP network, operators are able to use their network capacity in a much more flexible manner, through the dynamic allocation of capacity to an ever-increasing array of 3G services, such as:
-Push to talk, which is VoIP offered as walkie-talkie-like service;
-Packet-based video telephony, which combines realtime video with VoIP; and
-Simultaneous VoIP calls and data sessions.
