Fujitsu Microelectronics America, Inc. (CITY, CA) has made available a new white paper on WiMAX, "RF Spectrum Utilization in WiMAX." A follow-up to the company's first white paper on WiMAX, "WiMAX Technology and Deployment for Last-Mile Wireless Broadband and Backhaul Applications," published in August 24, 2004, this new document reviews the frequency spectrum requirements for implementation of the IEEE 802.16REVd (WiMAX) broadband wireless standard. It covers band diversification, regional variations, and transmit/receive requirements for WiMAX systems, and also highlights 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.

The nine-page WiMAX white paper, which can be downloaded at the link below, explores the growth prospects for the emerging Wireless MAN 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 expansion of the WiMAX spectrum also are included. Copies of the first white paper are available at the link listed below.
