October 2003 - In This Issue [Cover Story] Chip Set Withstands WLAN's Future Blows The furious pace of WLAN announcements is almost drowning engineers. Because they're being inundated with so much information, it's hard for engineers to separate marketing hype from technical fact. Yet certain truths do exist. For example, the WLAN... — Cheryl Ajluni [Design Application] Wireless Invades The Medical Front In the world of medical science, mobile circuits are quickly evolving into less cumbersome devices. They are providing more information and using less power. At the same time, they're improving quality of life. Although this evolution is only... — Thad Smith [Product Features] Alchemy Works Magic On Mobile Devices One of the brightest stars in today's technology constellation continues to be the wireless market. Big and small players alike have joined in the consumer craze for wireless products. New devices are based on everything from 2.5G and 3G technology... — John Blyler Coprocessor Synthesis Offloads Software Tasks For experienced wireless designers, the migration path from software to hardware is a familiar one. After all, newer technologies are first implemented in software to gain efficiency and expediency. Examples include Java, multimedia (MPEG-4), and 3G... — John Blyler Test-Vector Generation Draws Major Gains To design complex ASICs in a timely and cost-effective manner, engineers must incorporate various design-for-test (DFT) methodologies. Early on, for example, they must add boundary as well as internal built-in self-test (BIST) structures and scan... — John Blyler [New Products] EMI+ESD Device Benefits Liquid-Crystal Displays Compared to their predecessors, modern color displays have high data rates. As a result, it is essential to significantly reduce the display interface's capacitance. This approach will ensure the integrity of the display data as it passes through... — Staff Bluetooth Card Unleashes Industrial Handhelds To track their products, many delivery-service and warehouse employees use handheld terminals. Typically, these devices work by having the operator enter product information via a keypad or IrDA-based bar scanner. Now, the devices are entering the... — Staff Mobile-Access Solution Breaks Cost Barrier For universal, wireless mobile-data access, cost has been the main factor that's holding back growth. Of course, cost weighs down the growth of any leading technology. But its reign over the mobile-data arena may be about to end. Xpherix Corp. has... — Staff Co-Existence Software Limits Interference The rapid growth of Wi-Fi devices and the steady increase in Bluetooth-enabled products are resulting in increased signal interference. To address this problem, many hardware chip sets have been designed with accompanying software. Taking an... — Staff GSM Scanning Receiver Empowers Carriers As Global System for Mobile Communications (GSM) networks are rolled out across the U.S., the demand will grow for related receivers and measurement systems. Luckily, some companies are already prepared for this trend. For example, Dynamic... — Staff Wi-Fi DSL Router Widens Home's Networking Reach Once, wireless home networking was thought of merely as an add-on for broadband. Instead, it turned out that it actually improved the attractiveness of DSL. Wireless home networking has helped operators hold their customer base and even grow revenue... — Staff [Column] Will EDGE Have A Fairy-Tale Ending? For the last couple of years, it seems like EDGE has been playing the role of Cinderella to stepsisters CDMA and 3G/UMTS. I'm loath to describe these technologies as "ugly," as beauty is in the eye of the patent holder. Today, however, network... — Greg Matthews If CM Is Good, Outsourcing Will Be Better Good configuration management (CM) is seldom easy. It can become even more difficult when software-development teams are distributed across the globe. As the outsourcing trend in U.S. wired and wireless companies continues to grow, so too will the... — John Blyler Wireless-Systems Engineers Get Wired Into PCB Trends Wireless-systems designers are being pushed to find low-cost ways to pack higher performance and greater functionality into smaller packages. For many, the solution is to combine digital, analog, and RF technologies. To reduce time to market,... — David Wiens [News] On The Wireless Front Santa Clara, California California Eastern Laboratories (CEL) recently announced the availability of an uncooled, 1310-nm, directly modulated laser-diode module. Hailing from NEC, it is designed for the 10-G... — Staff Short Clips Recently, Royal Philips Electronics (www.semiconductors.philips.com) introduced a low-power 802.11b solution. This solution plans to address the new era of handheld multimedia products, in which integrated WLAN access reaches corporations,... — Cheryl Ajluni PA Module Urges Smart Phones To Diversify Modern cellular phones perform a varied array of tasks. They can connect to the Internet, take and send photos via e-mail, and keep their users organized and on time. Meanwhile, innovation in personal communications and handheld computing is forging... — Cheryl Ajluni Telemedicine Slips Into A T-Shirt Right now, society is witnessing wireless technology's transformation of the medical field. As the primary vehicle of this change, most people can easily imagine a small, intricate device like a pacemaker. No one imagines a T-shirt. Yet the first... — Nancy Friedrich Calendar CTIA Wireless I.T. & Entertainment... — Nancy Friedrich Interface Displays Open-Source Potential So far, mobile consumers seem to be easily drawn to the ability to play games, view videos, or exchange pictures. This trend is turning the display from a component into a winning feature of the device. To make sure that future displays don't... — Nancy Friedrich Short Clips OSE Systems (www.ose.com), a subsidiary of Enea Data (www.enea.com), joined forces with other Enea Data subsidiaries: Enea Realtime and Enea TekSci consulting. Together, they will become Enea Embedded Technology. Operating as a subsidiary of Enea... — Nancy Friedrich Biometrics Takes Satellite Ride The government has long relied upon satellites to enhance security efforts and deepen investigations. In a new twist, it will soon be able to use satellite systems to send and receive biometrics data. In conjunction with Sun Microsystems... — Nancy Friedrich [Editor's Note] What's The Word On WLAN? These days, you really can't go anywhere without hearing something about Intel and Centrino. In one fell swoop, Intel seems to have dramatically altered the course of the WLAN and mobile-computing marketplaces.
