Fujitsu Cites Design Wins for WiMAX System-on-Chip

Fujitsu announced two design wins for its WiMAX System-on-Chip (SoC), which was introduced in April 2005.

  • MiTAC Technology, a global leader in PC, networking and communications products, has introduced a new indoor subscriber station based on the Fujitsu MB87M3400. The indoor subscriber station, which complies with the IEEE 802.16-2004 and ETSI HiperMAN standards, supports network routing, WiMAX-based Broadband Wireless Access (BWA), and voice over IP (VoIP). It connects with a WiMAX base station using a 3.5GHz wireless link to deliver high-speed voice, data and multimedia content.

  • Aperto Networks, a leading WiMAX systems provider serving more than 200 operators in 65 countries, has announced that its indoor, self-install WiMAX broadband wireless products for consumers will be available in the first quarter of 2006.
  • Fujitsu's chipset uses an OFDM 256 (Orthogonal Frequency Division Multiplexing) PHY that supports channels from 1.75MHz up to 20MHz, and can operate in TDD or FDD modes, with support for all available channel bandwidths. A programmable frequency selection generates the sample clock for any desired bandwidth. When applying 64QAM modulation in a 20MHz channel and using all 192 sub-carriers, the SoC's data rate can go up to 75Mbps. Uplink sub-channelization is also supported.

    The Fujitsu WiMAX SoC incorporates sophisticated processing power, including a main RISC engine that implements the 802.16 upper-layer MAC, scheduler, drivers, protocol stacks, and user application software. Also on board is a secondary RISC/DSP that functions as a co-processor, which executes lower-layer MAC functions, offloading processing from the upper-layer MAC and enhancing total performance. A multi-channel DMA controller handles high-speed transactions among agents on a high-performance bus.

    Fujitsu said its WiMAX SoC also incorporates radio control and all required analog circuits, along with a comprehensive set of integrated peripheral functions. To ensure security, the chipset uses DES/AES/CCM encryption/decryption engines for the 802.16 MAC privacy sub-layer. The chip also includes a memory controller, an Ethernet engine for interfacing to the network, and high-performance DAC/ADC for flexible baseband interface.
