Terabeam Wireless Announces Plans for WiMAX Systems Based on the Fujitsu System-on-Chip

TeraMax™ 3.0 Products To Include New “Logan” Operating System and Planned for General Availability in 4Q 2005

Falls Church, VA and Sunnyvale, CA
May 23 , 2005

Terabeam Wireless, the business name of YDI Wireless, Inc. (NASDAQ:YDIW), a leading developer and supplier of broadband wireless solutions, and Fujitsu Microelectronics America, Inc. (FMA), a leading provider of robust and highly integrated wireline and wireless system-on-chip (SoC) solutions for next generation networks, today announced that Terabeam has selected the Fujitsu MB87M3400 WiMAX SoC as the standard silicon for integration into Terabeam’s TeraMax™ 3.0 product family. The TeraMax™ 3.0 products will be WiMAX-compliant, will incorporate Terabeam’s new wireless network management operating system, code-named “Logan,” and are planned for general availability in the fourth quarter of 2005.

Terabeam will offer turnkey point-to-multipoint and point-to-point systems complying with the IEEE 802.16-2004 WiMAX standard as an extension of its TeraMax™ product series. Current TeraMax™ products have been providing customers with much of the functionality of WiMAX since 2004, such as orthogonal frequency division multiplexing (OFDM), adaptive dynamic polling, packet aggregation, and enhanced security options. TeraMax™ base stations, customer premise equipment (CPE), and bridges are available today for operation at multiple frequency bands – including the 4.9GHz band dedicated to public safety in the United States – and are also available in compact (integrated-antenna) and ruggedized enclosures. With a powerful combination of performance, versatility, and value, TeraMax™ systems are ideal for a variety of applications and environments for service providers, enterprises, municipalities, and public safety organizations.

The Fujitsu MB87M3400 is fully compliant with the IEEE 802.16-2004 WiMAX standard and can be configured to be used in both base station and subscriber station applications. It is designed to support frequencies ranging from 2 to 11GHz in both licensed and license-exempt bands. An on-chip OFDM PHY supports channel bandwidths from 1.75MHz up to 20MHz, and can operate in TDD or FDD modes. When applying a 64QAM modulation in a 20MHz channel and using all 192 sub-carriers, the SoC’s data rate can go up to 75 Mbps. The SoC incorporates sophisticated processing power, including a powerful main RISC engine that implements the 802.16 upper-layer MAC, scheduler, drivers, protocol stacks, and user application software. Also on board is a secondary RISC/DSP that functions as a co-processor, which executes lower-layer MAC functions, offloading processing from the upper-layer MAC and enhancing the total SoC performance.

“Logan” has been under development for over three years and was a significant driver of Terabeam’s acquisition in 2004 of KarlNet, Inc. Logan is a processor-agnostic operating system that can support multiple wireless modes (including 802.11 and the proprietary TurboCell® currently, and 802.16 by 4Q 2005) and is significantly more adaptable for ongoing development. Logan’s agility and versatility allow for a major streamlining of Terabeam’s software portfolio, and it enables support for quality of service (QoS), voice-over-IP (VoIP), state-of-the-art security and IPv6. Logan’s user interface and configuration and management tools provide for an enhanced user experience. Logan will be integrated into select Terabeam products throughout the remainder of 2005.

“Terabeam’s extensive range of broadband wireless networking products has been deployed around the globe by service providers, enterprises and government entities. The addition of WiMAX-compliant systems to our portfolio will build on our heritage of excellence in wireless networking,” said Robert Fitzgerald, Terabeam Wireless’ CEO. “The Fujitsu WiMAX System-on-Chip delivers the performance we require at an excellent price point, and we are pleased to have aligned ourselves with a leader in this exciting technology. In addition, our introduction of the Logan operating system to uniformly support all of our standards-based and proprietary products will result in a quantum leap in performance, scalability and management control in broadband wireless networking.”

“Terabeam’s decision to work closely with Fujitsu on its WiMAX development is very exciting and gratifying to our broadband wireless team,” said Keith Horn, senior vice president of marketing and sales for Fujitsu Microelectronics America. “It also underscores our contention that 2005 is truly the year in which WiMAX technology will emerge in multiple markets worldwide as the leading companies in the industry, like Terabeam, move forward with significant product development, compliance testing, and initial field deployments.”

Terabeam Wireless will be participating in ISPCON from May 24 to 26 at the Convention Center in Baltimore, Maryland, and will be showcasing its broadband wireless products in booth 318. Terabeam Wireless (booth 87019) and Fujitsu (booth 41015) will be participating in SUPERCOMM 2005 from June 7 to 9 at McCormick Place in Chicago, Illinois. Terabeam will host an executive briefing at 1:00 p.m. CDT on Tuesday, June 7 in Room #N427D (Level 4 in South Building, McCormick Place).
