Accelerated Technology's Nucleus 802.11 STA Delivers Wireless Ethernet Support to Nucleus Developers

EMBEDDED SYSTEMS CONFERENCE, Boston, Mass., September 15, 2003 - Accelerated Technology®, the Embedded Systems Division of Mentor Graphics Corporation, today announced the release of Nucleus 802.11 STA to developers requiring 802.11b or wireless Ethernet support to build their wireless application. The addition of 802.11b to the Nucleus^TM real-time operating system (RTOS) product line will allow users of the Nucleus RTOS to easily add wireless capabilities to their devices including multimedia appliances, infotainment devices, PDAs, digital cameras, cellular phones, DVD players, set-top boxes and portable radios.

802.11b, or wireless fidelity (Wi-Fi®), refers to a family of specifications for wireless local access network (LAN) technology. Wi-Fi, a term coined by the Wi-Fi Alliance, provides for wireless Ethernet transmission primarily between laptops and local access nodes that attach to the standard corporate LAN. While the office is a natural setting for Wi-Fi, the movement to wireless communication in the home has provided increased capabilities for personal Wi-Fi use. Cellular phones, PDAs and handheld Internet appliances are among many devices that now carry wireless Ethernet capabilities allowing users to connect with others across the room or across the country without the limitations of physical wires.

Nucleus 802.11 STA, a wireless Ethernet driver for wireless STAtion devices, gives developers a robust and easy-to-use solution to build their wireless application and get it to market quickly. The 802.11b support plugs seamlessly into the Nucleus NET, Accelerated Technology's TCP/IP protocol stack. Nucleus 802.11 STA supports infrastructure and ad-hoc mode, wired equivalent privacy (WEP) security, and has been tested against multiple off-the-shelf PC Cards. Nucleus 802.11 STA is also provided with well-documented source and without royalty fees.

"Wi-Fi, which has been a hit on the desktop, is quickly becoming a must-have technology for many of our embedded customers, especially in the consumer electronics space," said Robert Day, director of marketing, Mentor Graphics Embedded Systems Division. "Because the Nucleus software dominates the commercial-off-the-shelf market for operating systems in this area, the addition of 802.11 technology to the Nucleus family of products was an easy decision to make. This will further strengthen our Nucleus product line for any applications that are considering adopting Wi-Fi."

Pricing and Availability
Available now, licenses for Nucleus 802.11 STA start at U.S. $7,495. For more information, please contact Accelerated Technology at 800-468-6853 or info@acceleratedtechnology.com.
