Qualcomm Incorporated (Nasdaq: QCOM), pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, announced today that the Company is joining TGn Sync, a cross-industry group, in its development of an Institute of Electrical and Electronics Engineers (IEEE)-sanctioned 802.11n standard proposal. Previously, Qualcomm was separately responsible for one of the four remaining 802.11n system proposals that were submitted to IEEE for the development of the next generation of high-performance local area wireless networks. Consistent with its decision to join TGn Sync, Qualcomm will withdraw its proposal from the IEEE process. The 802.11n standard is required to deliver a user throughput of 100 Megabits per second—nearly four times the performance of existing 802.11 a, g networks—and is widely anticipated to support the digital wireless home and office of the future.

Qualcomm’s support for TGn Sync’s proposal affords the group deep expertise in wireless technology, particularly with regard to Qualcomm’s leading edge Multiple Input Multiple Output (MIMO) technology which greatly improves wireless performance through the use of multiple transmit and receive antennas.

“As a recognized leading contributor to the IEEE 802.11n standards body, Qualcomm opted to align with TGn Sync to support the rapid introduction of a proposal that shares the same fundamental approach as ours and is strongly supported by numerous industry leaders,” said Ed Tiedemann, senior vice president of engineering, Qualcomm. “We believe that the TGn Sync proposal will serve as the fundamental basis for the 802.11n standard and provides the highest possible throughput and quality of service for next-generation wireless networks.”

TGn Sync is a cross-industry group working together to rapidly introduce a unified proposal for the next generation of high-performance wireless networks. The group’s proposal was developed under the guidelines of the IEEE Standards Association and submitted to the IEEE 802.11 Task Group N (TGn). TGn Sync’s proposal dramatically improves the capabilities of wireless networks while supporting the antenna configurations, product designs and protocol requirements of hundreds of millions of cellular handsets, enterprise base stations and Wi-Fi?-enabled computers already in use worldwide.

In a statement today, TGn Sync said, “By applying Qualcomm’s expertise in wireless and MIMO technology development, we are strengthening our proposal for the 802.11n standard. Working together, our cross-industry group will be in a much better position to advance the standard swiftly. The TGn Sync 802.11n proposal provides for both short- and long-term opportunities, providing for the useful application of the technology by both the consumer and enterprise markets, now and in the future.”

TGn Sync is comprised of 20 industry-leading companies across the cellular, computing, consumer electronics, enterprise networking, mobile radio, public access and semiconductor markets. For a list of the current members, go to
