September 2004 - In This Issue [Cover Story] Software Works So You Don't Have To Traditionally, the cover of Wireless Systems Design has featured a product, component, or design tool that in some way stands out from the rest. The cover product may flaunt lower power, lower cost, or higher performance. Or, it may have been... — Cheryl Ajluni [Special Report] Unrealistic Expectations Threaten WiMAX's Success Despite some great charitable and technological efforts, the disparity between the world's networked and non-networked populations seems only to have worsened. The better-connected populations are enjoying a move to next-generation cellular... — Nancy Friedrich [Design Application] Quality Devices Deserve Good Sound As audio quality becomes increasingly important in electronic systems, many more designers must become skilled in the "art" of analog and mixed-signal design. Some designers find this trend intimidating. In truth, though, an amplifier is still just... — Julian Hayes [Product Features] Entertainment Nears The Consumer Sweet Spot Many consider the wireless home to be the crowning achievement of the engineering future. Currently, numerous engineering companies are working on technologies that will enable wireless audio/video in such a home. Although very impressive... — Nancy Friedrich ZigBee Platform Readies Wireless-Based Designs Sometimes, a little can go a long way. For instance, take the case of ZigBee—a set of networking, security, and application software protocols based on the IEEE 802.15.4 low-data-rate wireless standard. Compared to other wireless networks, such... — John Blyler [New Products] One-Box Tester Supports Multiple Standards Until now, no technology has successfully measured both WLAN 802.11a/b/g and Bluetooth modules from a single platform. Agilent Technologies, Inc. recently changed that trend with its N4010A one-box test set. This product replaces the golden radio... — Staff Synthesizers Guarantee 12,000 Hours Of Operation Engineers are constantly seeking ways to improve their designs. They can now get help from Aeroflex, which has achieved major design improvements with the addition of the 2200 series to its line of fast-switching frequency synthesizers. This series... — Staff Design Kits Extend To VHF And UHF Power Amplifiers Designers need to go from design to production as quickly as possible. For help in achieving this goal, they can rely on the DAK-3A Design Accelerator Kit from the Semiconductor Division of Mitsubishi. This kit is the third in a series of advanced... — Staff Technology Helps Shrink Component Height Recently, Murata Electronics introduced the Planar High-density Passive Device (PHPD) technology for low-height components. This technology can be applied to many components, such as filters, diplexers, and mode transformers. The first... — Staff [Column] Hot Spot In A Box: The Missing Wi-Fi Link Joins With Linux A large gap exists in the wireless-product lines of most network-equipment manufacturers. That gap is one of needed functionality—in other words, access points that can be configured, monitored, and secured by standard network-management... — Kelly Abbott , et al. [News] Sensors Save Industrial Energy The industrial sector may not be the flashiest or most talked about wireless application area. Yet it is experiencing a high rate of growth and development. Thanks to recent support from the U.S. government, wireless' potential for industry should... — Nancy Friedrich Short Clips The Open Source Development Labs (www.osdl.org) announced a milestone: 22 major companies are now participating in and supporting the development of Carrier Grade Linux (CGL) specifications. Wireless Valley Communications, Inc.... — Nancy Friedrich Integration Spells Relief For Mobile Workers In many ways, the mobile-user experience remains clumsy and unsatisfying. A major part of the problem is the lack of integration between wireless local-area networking (WLAN) and wireless wide-area networking (WWAN). To make wireless access more... — Nancy Friedrich Java Comes In A New Blend Mobile devices can thank Java for the popular mobile games, ringtones, and other features that are currently driving the handheld market. As smart phones and personal digital assistants are showing, however, Java also feels at home in the enterprise... — Nancy Friedrich Design IrDA Products The Right Way Sometimes, it's easy to forget that infrared technology—as embodied by the IrDA community—is every bit as wireless as Bluetooth and Wi-Fi. In fact, IrDA is pervasive throughout today's electronic mobile systems. The most recent IrDA report... — John Blyler [Editor's Note] Not More WLAN Alphabet Soup! Just when you thought it was safe, another 802.11 standard variation has emerged on the scene. This standard is known as 802.11n. Its intention is to enable next-generation Wi-Fi, which is capable of sustaining data throughput in excess of 100 Mbps.... — Cheryl Ajluni [Around the World] Snapshots Ericsson Technology Licensing (www.ericsson.com/bluetooth) launched the "Ericsson Blue Pages." This guide offers a collected view of Bluetooth solutions for manufacturers of mobile phones, headsets, and other accessories. The first issue... — Nancy Friedrich [On The Wireless Front] On The Wireless Front Thanks to its introduction of a 256-kB, electrically erasable and programmable ROM (EEPROM) embedded smart card, Samsung Electronics Co. Ltd. now offers a full lineup of high-performance, high-capacity smart-card technologies. The smart-card... — Cheryl Ajluni |
