November 2002 - In This Issue [Cover Story] Prototyping Takes Center Stage Prototyping is a well-understood practice these days, especially in the wireless arena. Using multi-FPGA pre-silicon prototypes (PSPs), wireless engineers can simulate a system-on-a-chip (SoC) device at near-real-world speeds and under real-world... — Cheryl Ajluni [Special Report] Java Faces Competition From BREW and .Net Software designers have to make tough decisions when they select development environments for cellular-handset and PDA applications. Each of the major frameworks have their own strengths and weaknesses, whether it be Sun Microsystems' J2ME,... — John Blyler [Design Application] What You Need To Know About WLAN Clearly, the remarkable penetration of a simple, always-on wireless-Internet connection enabled by the IEEE 802.11 wireless local-area-network (WLAN) standards is no longer just a trend. In-Stat currently estimates more than 15 million regular... — Dr. William Lindsey Cooling Strategies Must Get Smarter For an electronic device, heat removal is critical to assuring proper operation and long-term reliability. Elevated operating temperatures can introduce circuit stability problems. They also can take semiconductor junctions to the point where they... — Dave Keller [Product Features] Digital, Analog, And Vector Modulation Merge Testing can be one of the most problematic steps in a design chain. When new technologies emerge, test equipment usually lags a step behind. As such, it is imperative that test equipment become more flexible. In addition, the equipment's user... — Nancy Konish Projection Keyboard Reveals Itself In this era, electronic devices are often considered "blind" to their environment. That's why the new offering from San Jose, California-based Canesta, Inc. stands out. It promises to give ordinary electronic devices the ability to perceive nearby... — Cheryl Ajluni [New Products] Power MOSFETs Set On-Resistance Records Designers of portable equipment must ensure battery protection while squeezing in on-resistance to extend battery life. To help them achieve this goal, Siliconix, Inc., a subsidiary of Vishay Intertechnology, Inc., has released five n-channel... — Staff Quad-Band Amplifier Serves GSM/GPRS Though budgets keep getting tighter, handset features continue to multiply. In response to this trend, designers are calling for components with more functionality and flexibility. The RF Components Division of Raytheon Co. has answered this call... — Staff Wireless-Internet Applications Get Tested To help wireless-Internet application engineers create, troubleshoot, and verify designs, Anritsu Co. is introducing a cdma2000 1xRTT wireless-Internet-protocol test solution. This solution verifies both software and hardware. The company promises... — Staff [News] Hope Rests On Location-Based Services The slow economy has sent carriers and manufacturers on a quest for revenue-bearing services. Meanwhile, the government is ordering compliance with Phase II e-911 requirements, and third-generation (3G) services finally seem to be coming into reach.... — Nancy Konish Full Internet Goes Mobile The most glaring problem with the wireless Internet has always been the screen sizes of mobile devices. Different solutions have included zooming, scrolling horizontally, or even scaling down Web pages. The industry also experimented with formats... — Nancy Konish Calls Pass From Bluetooth to W-CDMA Many carriers have been working on successful W-CDMA voice-call demonstrations. Meanwhile, an industry debate has continued raging over Bluetooth's market viability. Surprisingly, Qualcomm just cut through the mire of both of these issues by... — Nancy Konish RFICs Find Applications Everywhere The growth of smaller, more power-sensitive wireless-communication products has fueled the explosive development of RF integrated circuits (RFICs). Highly integrated RF components now populate ICs, replacing the hybrid circuits that used discrete... — John Blyler [Editor's Note] So That's The Next Big Thing Not long ago, the buzzword in wireless was "data." It was heralded as the driving force behind the migration to 3G. There was just one problem: Making consumers support this migration would take more than promises of access to lots of data.... — Cheryl Ajluni |
