Hitachi offers mobile IEEE 802.16e-compliant WiMAX solutions. Our total solutions encompass Access Service Network base stations (BS), ASN-GW, and the Operation and Maintenance Center (OMC). The ER3000 mobile WiMAX base station uses advanced S-OFDMA technology, MIMO technology, and the TDD system. The ER3000 mobile WiMAX system enables mobile broadband data communications. For application examples of the ER3000 Mobile WiMAX base station, see System Configuration.
The ER3000 mobile WiMAX ASN-GW is an access gateway accommodating mobile WiMAX base stations. The processor cluster architecture shares and balances loads according to the magnitude of traffic. It requires a small operation cost when the traffic is low following the initial introductory period and can be expanded in the future to cope with high traffic. ASN-GW complies with the QoS standard. In addition, it supports IPv4/v6 and Mobile-IPv4/v6 dual-stack modes to ensure compatibility with IPv6 when IP address depletion occurs.
