Introduction

Complete Wireless MAN Access

With a MAC-to-PHY implementation of the IEEE 802.16-2004 broadband wireless access (BWA) standard, the Fujitsu WiMAX SoC, MB87M3400, offers a cost-effective solution for both subscriber station and base station applications. This highly integrated SoC implements MAC, PHY, radio control and all the necessary analog circuits for the appropriate 2 to 11GHz licensed or license-exempt bands.

The Fujitsu WiMAX SoC, MB87M3400, fully complies with the IEEE 802.16-2004 standard using an OFDM PHY. The SoC can operate in TDD or FDD modes and supports all the available channel bandwidths from 1.75MHz up to 20MHz 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 subchannelization is supported as defined in the standard.

The SoC’s integrated ARM926 RISC engine implements 802.16 upper layer MAC, scheduler, drivers, protocol stacks, and user application software. A multi-channel DMA controller handles high-speed transactions among various agents on a high-performance bus.

To offload processing from the upper layer MAC and enhance performance, the Fujitsu WiMAX SoC includes a separate ARC RISC/DSP engine to execute 802.16 lower layer MAC functions. The chip’s multiple hardware-based encryption/decryption engines are tightly coupled with this lower layer MAC processor and can be enabled to provide full security for the MAC privacy sub-layer.
