KDDI Places 1xEV-DO Order
Hitachi says that it has won a CDMA2000 1xEV-DO radio access network contract from Japan's KDDI, for both 2GHz band and 800MHz band. KDDI will launch test service in April 2003 for 2GHz band systems and commercial service in autumn 2003 for 800MHz band systems. CDMA2000 1xEV-DO systems provided by KDDI consist of IP network, multi-vender radio access networks, and mobile terminals. Among these, Hitachi is responsible for radio access network.
The system being rolled out adopts IP based network architecture and provides a peak data rate of 2.4 Mbps within one 1.25MHz CDMA carrier. Due to high compatibility, CDMA2000 1xEV-DO can utilize existing CDMA2000 1x/cdmaOne cell sites, towers, and antennas.
Hitachi has been cooperating with KDDI to evaluate the performance and service of CDMA200 1xEV-DO by providing systems for field tests conducted by KDDI in Tokyo since 2000.'"
