KDDI plans to launch faster CDMA network this year

12 Sep 2006

CDMA mobile phone subscribers in Japan should see faster upload and download speeds later this year with an upgrade by operator KDDI.

KDDI, which uses the 'au' brand-name and is No. 2 in the Japanese cellular market, will boost the maximum download speed from 2.4Mbps to 3.6Mbps and the upload speed from 144Kbps to 3.1Mbps with the upgrade, it said.

The faster data transfer speeds will be available from December this year and will be made possible after KDDI upgrades its current network to cdma2000 1xEV-DO Rev.A. The lengthy moniker signifies the latest version of the CDMA cellular telephone technology and is a technology also likely to be employed by other CDMA operators around the world.

In addition to faster data transmission the upgrade also brings support for quality-of-service guarantees and services that require low network latency, such as VoIP and video telephony.

With the upgrade KDDI plans to offer both these two services, it said.
