NEC said it has successfully completed a trial of its HSDPA data service technology and is now gearing up to launch the offering commercially next fall. The company carried out the trial using Vodafone's KK network in Japan. NEC said the trial showed that Node-Bs and radio network controllers based on its HSDPA attained high levels of performance and functionality but did not specify data transmission speeds. The system was jointly developed by NEC and Siemens. In April, Ericsson tested its HSDPA over Vodafone's KK network in Tokyo, and Ericsson claimed the HSDPA-enabled base stations could support downlink bit-rates up to 3.6 Mbps and uplink rates up to 384 Kbps.
