QUALCOMM Successfully Demonstrates Fully Mobile VoIP Calls Across a Number of Field Test Environment
SAN DIEGO, June 7 -- QUALCOMM Incorporated (Nasdaq:
QCOM), a leading developer and innovator of Code Division Multiple Access
(CDMA) and other advanced wireless technologies, today 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(R) 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.
QUALCOMM used commercial-ready application specific integrated circuits in
both handset and prototype networks. These field tests validate the quality
and capacity of full mobility VoIP over EV-DO Rev. A and pave the way to large
scale commercial trials by network operators.
"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.
VoIP over EV-DO Rev. A leverages session initiation protocol, commonly
referred to as SIP, in combination with a number of advanced techniques to
achieve quality of service comparable to traditional landline voice. These
techniques include:
Comprehensive Quality of Service features, which enable operators to
provide multiple services on a common packet data platform;
Advanced call-hand-off algorithms, which ensure seamless operation in
the mobile environment;
Mobile receive diversity and equalization, which improve network
capacity and user experience; and
Enhanced speech-processing algorithms, which improve network capacity
and ensure high voice quality.
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 wireline 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.
"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 realtime audio, video and data streams their
service providers offer."
