CDMA Development Group Happy With Telecom New Zealand Upgrade Decision
Posted on 10-Jul-2006 18:57. | Tags Filed under: News.



The CDMA Development Group (CDG) has congratulated Telecom New Zealand (TNZ) on its commitment to deploy CDMA2000 1xEV-DO Revision A before the end of 2006. TNZ recently commited to CDMA2000 EV-DO Rev A to expand and enhance their network capacity and performance.

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.

CDMA2000 1xEV-DO Revision A is an enhanced version of 1xEV-DO Release 0, a broadband wireless technology deployed by cellular network operators, currently available from 36 networks across Asia, the Americas and Europe, with 37 more under construction.

Key benefits of Revision A include advanced services, mainly those impacted by real-time broadband, symmetric data link, and delay sensitive (low latency) such as voice-over IP (VoIP), push-to-talk (PTT), push-to-media, video conferencing, multicasting, and richly rendered 3D gaming with multiple players.

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.

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.

The average latency of Revision A is below 50 milliseconds, making it ideal for delay-sensitive applications such as VoIP, PTT, virtual private networks (VPNs), and simultaneous voice and data applications.

The new platform also enables the delivery of a wide range of applications with different levels of priority using enhanced Quality of Service (QoS) mechanisms.
