! The CDMA Development Group (CDG) is doing its best to talk up CDMA 3G technology and services in the face of growing market dominance by WCDMA. The CDG has announced that five major operators, KDDI (Japan), LG Telecom (South Korea), Sprint Nextel and Verizon Wireless (US) and Telecom New Zealand will be deploying commercial CDMA2000 1xEV-DO Revision A technology. "Collectively, these operators represent millions of mobile consumer and enterprise customers. These launches will further strengthen their respective market leadership and drive revenue from unrivalled broadband multimedia services," the CDG claimed. "Less than one year after the standard was finalised, Revision A is becoming a reality," said Perry LaForge, executive director of the CDG. "Commercial Revision A infrastructure is now available, and user devices will start shipping in the second half of 2006. This means that CDMA2000 operators will be able to provide their customers with enhanced broadband services as early as late this year, maintaining their leadership in advanced data services." CDMA2000 1xEV-DO Revision A is an enhanced version of 1xEV-DO Release 0 currently running on 36 networks across Asia, the Americas and Europe, with 37 more under construction. Revision A's key features include: - Increased peak download (forward link) rates to 3.1Mbps, making it able to support bandwidth-intensive applications such as video and transferring large files. - Symmetry. Revision A increases peak upload (reverse link) speeds to 1.8Mbps and is claimed to be the first commercially available wireless technology to deliver a true synchronic broadband experience. - Backward compatibility. Revision A networks support existing Release 0 applications and devices. - Low latency. Revision A has latency of 32 milliseconds, making it ideal for delay-sensitive applications such as push-to-talk (PTT), voice over IP (VoIP) and virtual private networks (VPNs). - Quality of service.  Revision A's enhanced QoS capabilities also makes it a fit for VoIP, video telephony and other services that require mechanisms in the network and user device to ensure a consistent, high-quality experience.
