Fujitsu Integrated Flexible WiMAX SoC Supports Femto Base Stations

Fujitsu Microelectronics Asia Pte Ltd (FMAL) has announced a Fujitsu mobile WiMAX base station SoC, an integrated, device built using the Fujitsu 65nm process technology. The scalable WiMAX SoC can support pico and micro base station architectures, enabling system to implement a single solution across multiple, small base-station platforms. The SoC incorporates all the PHY and MAC features along with the analog and digital radio control, and analog circuits required for base station products to pass Mobile WiMAX Wave 2 certification requirements. An on-chip processing unit delivers the power needed to handle all functions of a femto base station. For larger base station applications, an additional processor can be connected by means of a PCI host interface to handle larger demands for more throughputs and a bigger user base. The SoC also provides a full range of commonly used interfaces. The power requirements are approximately 2W, typically enabling a full femto base station to operate on less than 10W.



The Fujitsu femto solution supports up to 10 users with seven simultaneous flows, each with enhanced support for self-organizing networks and on-chip IPSec support for non-secure, back-haul traffic applications. The new SoC can be designed into femto base stations for indoor applications; into pico stations for indoor or outdoor applications by service providers or enterprise networks; and into micro base stations for outdoor use by service providers. Fujitsu has also developed a femto base station reference design kit that includes all required software and hardware for ODMs or contract manufacturers to build a cost-effective system solution. The SoC continues Fujitsu’s leadership in WiMAX technology, which began in April 2005 with the release of the MB87M3400, an integrated WiMAX system-on-chip that complies with the 802.16-2004 standard.
