June 2004 - In This Issue [Cover Story] Chip Set Widens ZigBee's Web Right now, a multitude of wireless-connectivity standards exists. Each of these standards promises to fill a unique void in the path toward total wireless-network connectivity. Many experts agree that getting to this connected reality is possible. Yet... — Cheryl Ajluni [Special Report] Misconceptions About Wireless Broadband Abound From the highest office in the land to the average consumer, everyone seems interested in high-speed, wireless Internet access. Even the United States government has deemed this topic important. It is now proposing the construction of base-station... — John Blyler [Design Application] Are Wireless Devices Too Hot To Handle? Cooling electronic enclosures was once a fairly straightforward job. First, one had to calculate the maximum heat that was dissipated in the enclosure. The next step was to calculate the maximum allowable temperature rise above the maximum expected... — Dave Keller Reduce The "Buzz" In Cellular Phones Harsh and noisy environments are commonplace for cell phones, personal digital assistants (PDAs), and other portable communications equipment. This fact has led to the development of new audio power amplifiers (PAs). These PAs offer fully differential... — Nicholas Holland , et al. Analog Designs Crave Dynamic Gain Control In the process of creating various products that deal with analog signals, one frequently requested function is automatic gain control. This feature is needed to control the amplitude of a given input signal so that it always remains within some... — Dave Bordui [Product Features] FPGA Prototyping Tool Aligns With ASIC Flow Over a third of all high-end ASIC designers now use FPGAs for prototyping 500,000-plus-gate designs. Driving this trend is the fact that a median application-specific integrated-circuit (ASIC) design can now fit onto the largest field-programmable... — John Blyler Platform Eases Hands-Free Bluetooth Design What if you could truly have hands-free cell-phone operation while driving down the road? Better yet, imagine that this capability was inexpensive, yet provided high sound quality. Texas Instruments believes that most cell-phones users would welcome... — John Blyler ESL Tools Enable Early Software Development Software development is the critical link in the development of today's embedded wireless applications. Some estimates place software creation at 50% to 70% of overall product-development costs. To remain competitive, wireless designers must be able... — John Blyler [New Products] Wi-Fi And RFID Devices Unite To Help Hospitals Wireless technology isn't new to the medical community. For years, doctors have been using laptops and PDAs with Wi-Fi connectivity to record patient records. In addition, many hospitals have experimented with various forms of wireless devices to... — John Blyler Low-Power FPGAs Put SRAM Into Small Package To meet consumer requirements for feature-rich, small, and lightweight mobile wireless devices, chip vendors have had to increase the density of their packages. One example is the low-power, high-density programmable-logic devices that were recently... — John Blyler Module Grants Many Devices Wireless Features Even though many device manufacturers want to join the wireless bandwagon, they lack the in-house resources to develop wireless connectivity. Now, help may have arrived in the form of Lantronix's WiPort module. This integrated device server supports... — John Blyler OFDM Building Blocks Help Speed WiMAX Development To accelerate the evolution of IEEE 802.16 or WiMAX networks, the industry may turn to devices that already have the flexibility to support this emerging standard. For example, picoChip recently developed a WiMAX PHY library that will run on its... — John Blyler Phone Boasts Keyboard And VPN-Client Capabilities Everyone talks about the next wireless "killer application." But users seem more interested in usability issues than the latest and greatest application. For this reason and others, Sierra Wireless has embedded a VPN client into its VoqMail... — John Blyler [Column] Unit Testing Emerges As Software Necessity These days, bringing a product to market is a frenetic experience no matter how it's done. The combination of a narrow market-opportunity window and tight development budgets dictates severe constraints. So it's no surprise that software testing... — Scott Thomas Will The U.S. Continue To Lead Wireless Standards? One measure of a region's technological power is its ability to set global standards. This capability directly reflects the region's knowledge base and global market share. Standards serve as milestones for the technologies as well. It's well known... — John Blyler Wireless Future Holds Engineering Challenges The increasing popularity of 802.11 wireless-local-area-network (WLAN) technology helps to prove that wireless is the wave of the future. Consumers want to be free from the confines of wires and cables. At the same time, they want to stay... — Brian Faith [News] Standard Addresses Wireless Multimedia One might assume that reading a book about the latest IEEE wireless standard would be about as fun as a trip to the dentist. Happily, Dr. Gilb's work is an easy read with a lot of graphics and sidebar notes. The aim of this book is to help individuals... — John Blyler Hardware Hacking Can Be Truly Fun I met the Technical Editor of this book, Joe Grand, at the recent "Design Wars" contest that I hosted for the Wireless Systems Design Conference & Expo. Joe took part in the contest by building a crystal radio. His eagerness to jump into a... — John Blyler How To Survive Doomed Software Projects Before reviewing the second edition of this book, I dusted off my copy of the original. It had served me well as a software-development manager. It had even helped me spot troubled projects that I should avoid. In addition, the first volume of... — John Blyler DSP + ARM Device Seeks Portable Data Terminals Often, people think that the wireless space is comprised solely of cell phones, PDAs, and wireless-networking devices. In truth, however, such products represent only a segment of this market's far-reaching potential. Take the fast-rising... — Nancy Friedrich DFS Series Beats Cost Constraints At this month's IEEE International Microwave Symposium (www.ims2004.org) in Dallas, Texas, attendees witnessed the latest in digital-frequency synthesizers (DFSs): the Low-Cost DFS Series Synthesizer from Elcom Technologies, Inc. (www.elcom-tech.com).... — Nancy Friedrich Full-Internet Phones Reach Japan The keys to success for a "wireless Internet" have been inspiring debate for years. Although consumers used the limited version of the mobile Internet, they didn't adopt it in droves. Many concluded that the consumer population was "spoiled" by its... — Nancy Friedrich Short Clips The NanoBusiness Alliance (www.nanobusiness.org) appointed Joseph Piché, CEO of Eikos, Inc. (www.eikos.com), to its Advisory Board. His objective is to guide the development of what has been called the Industrial Revolution for the... — Nancy Friedrich [Editor's Note] Where Do We Go From Here? Over the course of the past few years, the wireless industry has undergone a major transformation. Technological advances and economic hardship have resulted in major consolidation within certain market segments. Many wireless companies have simply... — Cheryl Ajluni [Around the World] Snapshots Optimi (www.optimi.com) announced its merger with TarTec (www.tartec.com). TarTec, based in Malaga, Spain, provides research engineering and advanced software products to the world's mobile carriers.
