Fujitsu Microelectronics America, Inc. (FMA) has released a white paper, “RF Spectrum Utilization in WiMAX,” which focuses on the WiMAX (Worldwide Interoperability for Microwave Access) standard and its implementation.
The paper discusses the frequency spectrum requirements for implementation of the IEEE 802.16REVd (WiMAX) broadband wireless standard. It also reviews the diversity of band spectrum for WiMAX-certified Metro Area Network (MAN) deployment, which is creating new demand for base stations and subscriber stations with varying RF requirements.
Additionally, the paper explores the growth prospects for the emerging Wireless MAN(TM) market based on the WiMAX (IEEE 802.16x) standard, and focuses on the control signals required for transmit and receive functions.
A detailed section reviews IEEE 802.16REVd, the version of the specification that addresses the point-multipoint architecture designed for last-mile applications. Brief sections on the RF-to-SoC interface and future expansionof the WiMAX spectrum also are included.
FMA is working closely with equipment and infrastructure vendors on a single-chip product that integrates PHY (physical layer) and MAC (media access control) functions.
The chip is targeted for use in base station and subscriber station applications, with a launch date currently set for the second calendar quarter of 2005.
