KDDI testing Qualcomm HDR technology ( longer story ) telecomclick.com [ Longer story, more detail than DJ wire story - DPR ] 08/10/00 06:11:45 PM Central Daylight Time By Kevin Fitchard, News Editor Aug. 10 (WirelessClick) - Japan's KDDI announced Thursday it has begun field trials of Qualcomm's High Data Rate technology, designed to deliver broadband Internet access to mobile and portable devices. KDDI, the company forming from the merger of wireless carriers KDD, DDI and IDO, is conducting field trials of the technology over its 800MHz cdmaOne networks through December with the help of Qualcomm, networking giant Cisco Systems and fellow Japanese technology company Hitachi. KDDI officials said at news conference today that Kyocera - which bought Qualcomm's CDMA handset division earlier this year - and Sony have agreed to make dual mode CDMA-HDR for the format once it is launched. Company officials, however, would not say when the services would be launched commercially. HDR is still in its formative stages with Japan doing most of the rearing. NTT Docomo's high-speed PHS service and IDO's own data services currently provide access speeds from 32Kb/s to 64Kb/s, far greater than the 9.6Kb/s to 14.4Kb/s available over most cellular and PCS networks but a far cry from the fat pipes of bandwidth promised by 3G. As the packet data technology becomes more sophisticated and IP network cores are deployed, those rates are expected to increase astronomically. While still primarily in the test phases, Qualcomm has been pushing its HDR format Air Link infrastructure as an alternative or transitional technology to 3G. The infrastructure can be grafted onto existing CDMA networks and can run concurrently with voice service. Qualcomm also touts the spectral efficiency of the technology, capable of squeezing 2.4Mb/s through a dedicated 1.2MHz channel. Qualcomm claims that the average data rates for a loaded sector would be about 600Kb/s on the downstream and 220Kb/s on the upstream, speeds nearing what many fixed-line and fixed-wireless broadband carriers are now offering customers. Unlike many broadband services like DSL though, individual subscribers aren't allocated dedicated bandwidth on the network. But bandwidth is reallocated as quickly as every 1.67 mSec, giving subscribers the maximum available bandwidth at any given moment, Qualcomm said.
