Press Release - February 14, 2005 Quorum Systems Launches First CMOS-Based Multi-Mode GSM/GPRS/EDGE+WiFi Radio Frequency Transceiver Single-chip solution enables small, low-cost convergence handsets 3GSM, Cannes, France -- February 14, 2005 -- Quorum Systems, Inc., a fabless semiconductor manufacturer specializing in multi-mode, multi-band single-chip radio transceivers, announced the introduction of the Sereno(TM) QS2000, the first in a family of single-chip CMOS transceivers that offer simultaneous multi-mode operation. Integrating support for 802.11b/g and GSM/GPRS/Full EDGE technologies, the QS2000 enables simultaneous voice and data operation, seamless hand-off between cellular and Wi-Fi networks as well as enhanced make-before-break performance. The Sereno QS2000 is optimized to meet the demands of small form factor multi-mode cellular handsets. Manufactured in low power, low cost CMOS technology, the Sereno QS2000 offers an unparalleled degree of integration that reduces component count and footprint, which in turn offers lower overall cost, improved production yield as well as reduced design time and time to market for customers. "This highly integrated device offers multiple benefits such as improved functionality, greatly reduced size and lower bill-of-materials to cell phone manufacturers and carriers," stated Bernard Xavier, Quorum Systems' president and CEO. "One big advantage in using CMOS is that we are able to produce unprecedented performance in a cost-efficient manner which in turn offers significant cost benefit to handset manufacturers." The Sereno QS2000 achieves simultaneous operation by using Quorum's Multi-Access Technology (QMAT) underlying proprietary intellectual property (IP), which allows the radio resource to be shared, enabling multi-mode functionality while reusing passive and silicon real estate. Also as a result of the QMAT technology, interference, which previously led to costly handsets and the delayed adoption of multi-mode radio band technology in handhelds, has been eliminated by the Sereno QS2000 multi-mode single-chip transceiver. "The Sereno QS2000 is the first released chip in a series of new CMOS-based multi-mode products," explained Xavier, "We are actively developing a number of chips that comply with the array of standards in cellular telephony and expect to be making them available in the very near future." The QS2000 is available for sampling today. About Quorum Systems, Inc. Quorum Systems is a fabless semiconductor company that develops highly integrated multi-mode radio frequency (RF) transceivers.
