CHICAGO -- Fujitsu Microelectronics America, Inc. (FMA), a global leader in WiMAX-compliant broadband wireless technology, today announced a new Fujitsu mobile WiMAX base station SoC, a highly integrated, flexible device built using the leading-edge Fujitsu 65nm process technology.

Designed to meet the cost requirements of a femto base station architecture, the scalable WiMAX SoC can support pico and micro base station architectures, enabling system manufacturers to implement a single solution across multiple, small base-station platforms.

The new 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 throughput 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.

“There is growing demand for small base-station platforms that have significantly lower capital and operating costs compared with macro base stations,” said George Wu, director of the Fujitsu Wireless Solutions Business Group. “The use of many smaller base stations can provide coverage and increase capacity, while reducing user churn because of disappointing performance. Our new mobile WiMAX base station SoC is designed with the flexibility to meet those requirements, with all the features and performance to assure system certification.”
