For Immediate Release
SiP or SoC? Wireless Semiconductor Technologies & Economics
at WCA November 21 Meeting
Expert Presenters: Dr. Rajeev Krishnamoorthy of Tzero Technologies and
Dr. Winston Sun of Atheros Communications
Silicon Valley, November 8, 2006 – The November 21 Wireless Communications Alliance (WCA)
meeting will feature presentations from Atheros Communications and Tzero Technologies discussing SiP
(System-in-Package) and SoC (System-on-Chip) wireless semiconductors. The presenters will each
discuss their technologies and the economic decisions involved in the development of each approach.
The meeting will take place on Tuesday, November 21, from 4:00 to 6:00PM at Cadence System Design
Corporate Headquarters, 2655 Seely Ave., Building 5, San Jose. Directions and additional information
are available on the WCA website at www.wca.org.
Tzero Technologies supplies ICs that enable high-definition DVD-quality video over wireless networks.
The company's ultra-wideband (UWB) wireless technology is driving the emergence of a completely
wireless home or office where consumer electronic devices and computer equipment are capable of
delivering broadcast-quality video. Dr. Rajeev Krishnamoorthy, CTO and founder of Tzero, has spent
nearly two decades creating, developing, and commercializing novel, advanced wireless communications
systems. Dr. Krishnamoorthy is also a Consulting Professor at Stanford University in the Electrical
Engineering department.
Atheros Communications develops semiconductor system solutions for wireless communications
products. Atheros combines wireless systems expertise with high-performance radio frequency (RF),
mixed signal and digital semiconductor design to provide highly integrated chipsets that are
manufacturable on low-cost, standard complementary metal-oxide semiconductor (CMOS) processes.
Atheros technology is being used by manufacturers of personal computers, networking equipment and
handsets. Dr. Winston Sun is a member of the Atheros development team.
“November's event will focus on the interface and interplay between economic goals and technological
realities of the SiP versus SoC decision,” said Rick Ellinger, President of the WCA. “The speakers will
describe how they made their initial design selection and overcame technological challenges. They will
also offer their perspectives on how semiconductor technology might evolve in order to meet future
market demands.”
About the Wireless Communications Alliance (WCA)
The Wireless Communications Alliance, founded in 1993, is a Silicon Valley-based, non-profit business
league of 2000 individuals and 350+ companies and organizations dealing in wireless technology and
markets. The goals of the WCA are to promote education, networking and exchange of non-proprietary
information; increase awareness of Northern California’s vast wireless capabilities; and assist a broad
spectrum of companies, including start-ups. The WCA organizes monthly meetings with presentations on
a wide spectrum of topics including the technical and marketing aspects of wireless products and services,
regulatory issues, wireless standards and investor-driven wireless market analysis. The web site,
www.wca.org, lists current events as well as past presentations and other pertinent information relating to
the wireless space. The WCA is run by an all-volunteer Board of Directors.
