CDMA2000® OPERATORS TO BE FIRST TO OFFER CARRIER-GRADE VoIP
1xEV-DO Revision A to Provide Unprecedented Gains in Speed, Capacity and OpEx
CTIA WIRELESS IT & ENTERTAINMENT, LOS ANGELES, Sept. 12, 2006 — The CDMA Development Group (CDG) (www.cdg.org) today announced that CDMA2000® operators upgrading to 1xEV-DO Revision A (Rev A) with conversational QoS capability will be the first to offer carrier-grade voice over internet protocol (VoIP) communication services over wireless 3G networks. Beyond supporting an entire new line-up of real-time and concurrent services that use VoIP packets, this evolutionary upgrade will enable network convergence and an associated reduction in operating expenses. Specifically, QoS enabled Rev A networks will increase downlink and uplink speeds, provide symmetry, and reduce latency and jitter for delay sensitive services that require increased levels of priority. Such services include: voice-over IP (VoIP), push-to-talk (PTT), push-to-media, video conferencing, multicasting, and richly rendered 3D gaming with multiple players.
“Being able to offer carrier-grade VoIP services over a mobile network is one of the biggest breakthroughs to come along in years,” said Perry LaForge, executive director of the CDG. “VoIP over cellular is not only more flexible and affordable than circuit-switched networks; it will help enable the convergence of telecommunications with entertainment, consumer electronics and information technology.”
EV-DO Rev A has been standardized by the Third Generation Partnership Project 2 (3GPP2) and has been enhanced to support delay sensitive and real-time applications using fast call setup, short transmission time intervals, variable packet length transmissions, fast and efficient management of IP packet headers through compression (RoHC), fast hybrid automatic repeat requests (HARQ), incremental redundancy feedback in the uplink, fast and efficient link layer control messaging, quality of service (QoS), antenna diversity, and rapid base station switching (handoffs) controlled by the mobile device. These tightly related technological breakthroughs enable Rev A to deliver the highest performance and lowest cost for most any kind of mobile application. No other wireless technology can match its maturity and flexibility. Rev A’s support for VoIP will tip the balance between circuit and IP-based packet networks.
Mike Iandolo, president of Mobility Access Solutions for Lucent Technologies’ Network Solutions Group , commented, “With Rev A, operators will have the ability to quickly deploy VoIP-based applications that blend voice, data, video and multimedia capabilities to meet the mobile communications needs of most subscribers around the globe. Lucent believes that Rev A is an essential element in the movement towards an all-IP world, and with the CDMA community, we’ll be one of the first to make this a reality.”
“CDMA2000 Rev A delivers on the speeds, ease-of-use, and transparent access to IP-based voice, multimedia and broadband data services to create an unparalleled user experience,” said Darren McQueen, senior director, CDMA, Motorola. “Rev A brings carrier grade VoIP to life. Motorola’s introduction of Rev A networks allow for a new user experience with concurrent services, while providing a platform for the rapid introduction of other feature-rich applications that will give CDMA operators the upper hand in differentiated services.”
Doug Wolff, vice president and general manager for CDMA, Nortel, added, “Building on the success of CDMA2000 1xEV-DO, the evolution to Rev A will allow operators to use the same spectrum they have always used to continue delivering a large variety of new, innovative and feature-rich IP applications to their customers. Rev A’s industry leading performance enhances an operator’s quality of service for supporting delay-sensitive conversational services, such as push-to-talk and video telephony.”
“Because the combination of Rev A and VoIP deliver increased voice capacity, operators will be able to deliver phone calls at a lower cost over broadband than today’s circuit-switched technology,” said Randy Battat, chief executive officer of Airvana. “That creates a compelling business case to deploy mobile broadband everywhere. The result is a ‘virtual circle’ of lower costs, enabling new multimedia applications, leading to increased revenues, driving more deployment, and even lower costs.”
