Resonext Two-Chip CMOS Dual Band 802.11a/b/g WLAN 
Chipset Chosen as Product of the Month

    SAN JOSE, Calif., Dec. 5, 2002 - Resonext(TM) Communications, Inc., a leading provider of highly integrated two-chip CMOS solutions for Wireless LAN (WLAN) platforms, announced today that the Resonext RN5220, the world's first two-chip CMOS dual band chipset for 802.11a/b/g applications, has been named the "RF Design Magazine Editors' Choice for Product of the Month" in November.

    "We are honored that the editors of RF Design chose the Resonext RN5220 dual band chipset as product of the month," said Resonext Marketing VP Robert Fan. "By incorporating the industry's first single-chip dual band 1.8V CMOS radio based on zero-IF architecture, our dual band chipset lowers bill of materials costs and reduces power consumption -- both very important features for our customers."

    Resonext first demonstrated its new RN5220 dual band chipset last month at Comdex Fall 2002 and continues to conduct private demonstrations for Original Equipment Manufacturers (OEM) and Original Design Manufacturers (ODM). The RN5220 dual band chipset will sample this quarter to alpha customers, with volume production scheduled for the first half of 2003.

    Mr. Fan, a recognized authority on dual band technology in today's wireless LAN environment, will discuss dual band chipset performance and design advantages during a panel on technology trends at the 802.11 Planet Fall 2002 Conference & Expo today in Santa Clara, Calif.

    The Resonext RN5220 dual band chipset is based on the company's flagship product, the RN5200 802.11a chipset, which was also named the "RF Design Magazine Editors' Choice for Product of the Month" in January, 2002. The RN5220 802.11a/b/g chipset consists of a single-chip dual band CMOS radio and a multi-protocol baseband/MAC chip, both manufactured on the 0.18-micron, 1.8-volt CMOS process from Taiwan Semiconductor Manufacturing Company (TSMC).

    The Resonext RN5220 dual band chipset is compliant with IEEE 802.11a/b standards and is designed to fully support the emerging 802.11g specifications with a data transfer rate of up to 54Mbps. The chipset features Resonext's proprietary AccuChannel(TM) equalization technology, which increases the Signal-to-Noise Ratio (SNR) by up to 4dB and provides up to a 32 percent greater range for all data rates when compared to standard OFDM modems. A flexible MAC architecture supports customer differentiation and evolving IEEE drafts for Security (802.11i and Wi-Fi Protected Access), Quality of Service (802.11e), Dynamic Frequency Selection and Transmit Power Control (802.11h).
