TNZ to Upgrade Entire CDMA2000 Network to Enable More Advanced Broadband Services in 2006


AUCKLAND, New Zealand, July 12, 2006 — The CDMA Development Group (CDG) ( congratulated Telecom New Zealand (TNZ) on its commitment to deploy CDMA2000® 1xEV-DO Revision A before the end of 2006. TNZ recently announced that CDMA2000 has proven to be a superior technology in delivering 3G broadband services. With EV-DO Revision A, their network capacity and performance will be further enhanced to enable additional competitive service offerings. The Revision A network will also provide TNZ with a smooth upgrade path to EV-DO Revisions B and C to begin offering ultra broadband services within the next few years.

"The CDG applauds TNZ’s decision to bring this innovative technology to market," said Perry LaForge, executive director of the CDG. "In markets around the world, Revision A will demonstrate CDMA2000’s greater performance, flexibility, and one to three year time-to-market advantage over competing technologies.”

“Our decision to deploy Revision A reflects our desire to deliver the best performing and most cost-effective services to our subscribers,” commented Kevin Bowler, general manager of consumer marketing, TNZ. “Revision A will allow us to offer richer, more compelling and faster mobile data services to our consumer and enterprise customers. They will be the first to experience the value of enriched multimedia communications and enhancements to enterprise productivity.”

CDMA2000 1xEV-DO Revision A is an enhanced version of 1xEV-DO Release 0, a broadband wireless technology currently available from 36 networks across Asia, the Americas and Europe, with 37 more under construction. The key benefits of Revision A include:

  • Advanced services – Revision A enables the enhanced performance of a large variety of real-time broadband, symmetric data link, and delay sensitive (low latency) services such as voice-over IP (VoIP), push-to-talk (PTT), push-to-media, video conferencing, multicasting, and richly rendered 3D gaming with multiple players.
  • Improved Broadband speeds – Revision A increases the efficiency and speed of existing EV-DO networks, resulting in an improved user experience on existing applications. Peak download (forward link) and upload (reverse link) data rates are increased to 3.1 Mbps and 1.8 Mbps, respectively, in a mobile environment. These speeds will support a wide range of bandwidth-intensive applications.
  • Increased Capacity – On both the forward and reverse link, Revision A allows operators to support more users and it improves the cost of delivering voice, data and multimedia services.
  • Symmetry – By increasing uplink speeds, Revision A will be the first commercially available wireless technology to deliver a true synchronic broadband experience. Symmetry is important for applications where users send packets of data as often as they receive them, such as receiving and sending email with attachments.
  • Low latency – The average latency of Revision A is well below 50 milliseconds, making it ideal for delay-sensitive applications such as VoIP, PTT, virtual private networks (VPNs), and simultaneous voice and data applications.
  • Quality of service – Revision A enables the delivery of a wide range of applications with different levels of priority using enhanced Quality of Service (QoS) mechanisms. These mechanisms will ensure a consistent, high-quality user experience.
  • All-IP – Internet Protocol (IP) is the foundation for all future CDMA2000 radio access networks. Like 1xEV-DO Release 0, All-IP Revision A networks will continue to enable operators to enjoy additional service flexibility and higher bandwidth efficiencies, which translate into greater control and significant cost savings.
  • Backward compatibility – Revision A networks support existing Release 0 applications and devices. As a result, existing Release 0 customers will continue to drive revenue long after operators have deployed Revision A. This backward compatibility preserves an operator’s previous network investments, and is particularly important for enterprises who want to continue to leverage their investment in EV-DO Release 0 equipment for years to come.
