Alvarion and Hitachi Communication Technologies have agreed to develop Broadband Mobile Wireless Access System using Mobile WiMAX technology jointly in Japan and overseas market.

WiMAX is considered as the most likely candidate for Broadband Mobile Wireless Access Systems. To establish WiMAX technology, the base station, which can transmit broadband data stably, and the mobile management technology, which can realize seamless handover between base stations, are needed.

The main goal of this agreement is that Hitachi and Alvarion will develop total system solutions, combined with the base station technology of Alvarion with the mobile gateway technology, construction and maintenance technology of Hitachi, which has experience of 3G Mobile Radio Network System.

Hitachi Com is in charge of developing Access Service Network Gateway (ASN-GW). This can flexibly be expanded along by the future traffic increase through separating protocol processor from traffic processor. It has a non-stop configuration to realize the quality of carrier grade so that it can switch to the redundant system without giving any impact to other equipment such as base stations and mobile stations.

Alvarion is in charge of developing high performance macro/micro base stations. The company aims to realize the reduction in size and weight of base stations by function aggregation (unified RF parts and digital processing parts, 30% less power consumption and 50% less mass), and to reduce the power consumption in the RF portion with the advanced technologies such as DPD and CFR. The base stations will be compatible with AAS and MIMO which are key features in the WiMAX Forum Wave 2 specifications. As a result of combining MIMO and AAS together, effective cell design can be accomplished easier and both area coverage and system capacity increase.

Through the experiences of Hitachi, with mobile management technologies proven in the 3G mobile communication market, and Alvarion, which has the wireless broadband technology from OFDMA down acquired in the fixed WiMAX with high market shares in the world, they can realized new WiMAX system which has the quality of career grade still maintaining WiFi-like easy deployment capability.

Hitachi Com will aim for further global expansion in the next generation broadband wireless business through this scheme.
