Tropian to Discuss Development Path of 3G Handsets at Semiconductor Conference in London

date: September 13, 2001

Tropian, a Silicon Valley-based wireless communications product company, announced that Richard Lodge, Director, Market Applications, will address key challenges and recommendations for development of semiconductor devices for 3G handsets at this week's Chips for Mobile Handsets conference in London.

The conference, "Optimizing the Marketability of Chips For Mobile Handsets," opened yesterday and continues through today at the Euston Plaza Hotel in London. Attendees are examining emerging trends in the mobile handset market and their impact on communications chip designers. In addition, the conference goal is to identify and predict 2.5G and 3G functionality to minimize research and development risks.

As the wireless industry begins to offer higher bandwidth 3G services including email, web browsing and messaging, handsets will be challenged by higher processing rates, higher part count and signal purity. Lodge's presentation, "Optimizing Power Efficiency of Semiconductor Devices for 3G Handsets, from 5:00-5:40 p.m. today, will focus on how the wireless industry can deliver high-speed data while meeting consumer expectations of small product size, long battery life and clear signal. According to Lodge, although there are several standards in development for 3G wireless systems, EDGE/GPRS may be the best choice for the immediate future as the standard will allow sufficient delivery of bandwidth while optimizing battery life and part count. Lodge will also join the panel session "Meeting the Requirements of the Next Generation Mobile Terminals with Innovative Chip Design" today from 12:10-12:50 p.m.

Once EDGE/GPRS is decided upon, Lodge recommends architecture design using polar modulation rather than traditional PA linearization. While linear designs can suffer trade-offs between signal purity and efficiency, polar modulation can offer both spectral purity and efficiency. In addition, because polar modulation design is a digital configuration, there is opportunity in the future for integration with other handset parts, thus allowing for reduction of part count and product size.

"As the industry rolls out its next generation of wireless service, it must consider consumer expectations set by widespread use of digital voice systems," Lodge said. "With EDGE/GPRS technology and a polar modulation architecture, we can deliver high-speed data along with efficient modulation and performance."

M-Profits: Making Money from 3G Services
ISBN: 0470847751

This book discusses 3G services from the view of what is needed for the service to provide value to the user, what is the value proposition for the user, how will money be made out of delivering the service, and discussions on how revenue sharing propositions might work to benefit content providers and network operators. 3G operators should take note of this highly recommended book.
