September 2003 - In This Issue [Cover Story] Location-Based Services Are Positioned For Growth To many people, "location-based services" (LBS) is just one long buzzword. The average American consumer is probably familiar with some of the capabilities of the FCC-mandated e-911 initiative. But he or she has had little real exposure to LBS... — John Blyler [Design Application] System Verification Comes To SystemC It is widely accepted that system verification is the most imposing obstacle to meeting time-to-market schedules. Now, the verification process has become even more time-consuming and expensive. These factors can be attributed to rising chip... — Adam Rose Analyze And Optimize Throughout The Flow The increased use of portable, wireless, battery-powered electronic systems is driving the demand for integrated-circuit (IC) and system-on-a-chip (SoC) devices. After all, these devices consume the smallest possible amounts of power. With every new... — Sameer Patel Measurements Put WLANs To The Test Within business IT infrastructure, wireless is becoming an accepted and often expected mode of data communications. A myriad of hardware vendors and technologies exists, however. To gain maximum performance, an employed WLAN system must therefore use... — Jason Manous W-CDMA Signals Now Take Center Stage Emerging wireless standards bear many implementation challenges. A technology like Wideband Code Division Multiple Access (W-CDMA), for example, is new territory for many designers. Its signals are wider in bandwidth and they are more complex in their... — Koichi Sega MLC Challenges Mobile-Entry Barriers Smart phones, personal digital assistants (PDAs), and other devices are luring users with increased functionality and personalization options. These designs are based on standard operating systems. They have PC-like functionality and an operational... — Raz Dan , et al. Batteries Bear The Digital Load's Burden As the world moves from analog to digital communications devices, new demands are being placed on the battery. While analog transceivers draw a steady current, the digital radio loads the battery with short, heavy current spikes. For example, the... — Isidor Buchmann [Product Features] Cellular Memory Swaps In The Next Generation Although they have been hyped for many years, high-data-rate cellular networks are now becoming a reality. As more communities are upgraded with 2.5G and 3G infrastructure systems, consumer interest is growing in the networks' potential benefits. But... — John Blyler Gain Amplifier Eyes 30-To-300-MHz Range The rollout of 2.5 and 3G networks is quickly gaining momentum. North America, for example, is witnessing the ongoing build-up of GSM/GPRS cellular network systems. In addition, one major U.S. carrier is in the process of deploying that region's first... — John Blyler [New Products] Tool Family Slashes Design-Verification Time Baseband design iterations are known to incur costs while robbing designers of time. One way to avoid these pitfalls is by reducing the number of iterations. Agilent Technologies recently released Baseband Studio for that very purpose. This new... — Staff Small Analog Switches Pack A Powerful Punch Seven low-voltage, high-performance analog switches now flaunt what's said to be the industry's smallest package footprint—just 1.6 × 1.6 mm. Known as the DG2000 series, these switches are designed for routing and selecting signals in... — Staff High-Performance SiGe Mixers Reject Emissions Most conventional mixers are passive solutions. As a result, they have a higher risk of spurious emissions. In contrast, Atmel's ATR0785, ATR0786, and ATR0787 products are active components. By providing a conversion gain of about 17 dB, each device... — Staff Single-Handed Keypad Enables Fast Text Entry Typing speed is a significant bottleneck on today's cell phones. Now, a single-handed-operation, alphanumeric-keypad design is working to eliminate this problem. By providing a 300% typing-speed increase, the Delta II technology allows cell-phone... — Staff Transistors Satisfy Infrastructure Needs Infrastructure equipment for CDMA, GSM, and EDGE always craves improved RF transistor performance. In response, Motorola has designed a series of 100-W, 900-MHz RF power transistors in plastic packaging. These transistors also promise to deliver... — Staff One-Stop Solution Speeds Cell-Phone Development To ensure a product's success, it is vital for manufacturers to bring compact, feature-rich mobile telephones to market more quickly and easily than ever before. The Compact Phones Development Lab has emerged to aid handset manufacturers in those... — Staff [Column] Fashion Will Drive The Next Electronics Wave Ever since electronic devices like cell phones and laptops arrived on the market, performance characteristics have been their mainstay. Today's technology playing field, however, has largely been leveled by global access to state-of-the-art... — Tom Tarnowski Defense Labs Hustle To Regain Wireless Expertise Are you a former defense professional? Maybe you worked for the Department of Defense (DoD) or one of the many contractors that support the U.S. military complex. Most wireless-systems engineers started their professional careers on defense-related... — John Blyler [News] Multimedia Technology Charms Handset Industry Remaining competitive in these tough economic times can be a challenge. It's even more difficult to thrive against other major players. Yet somehow, the Santa Clara, California-based Nazomi Comm. seems to have succeeded on both of these fronts. At the... — Nancy Konish Calendar Embedded Systems Conference Hynes Convention Center, Boston, MA September 15-18,... — Nancy Konish Mobile Entertainment Proceeds Forward These days, the term mobile entertainment is creating a big buzz in the wireless industry. Gone are the days when a cell phone was merely used to place and receive calls. Now, consumers demand access to a number of features—not the least of which... — Nancy Konish Short Clips Tropos Networks (www.troposnetworks.com) received an investment from the Intel Communications Fund. Tropos and Intel also plan to participate in joint marketing activities. The investment by Intel Communications Fund is part of its $150 million... — Nancy Konish Mobility Radiates Out From The User In a perfect wireless world, users would be able to access cellular and wireless LANs from a single handset. They would have coverage across enterprise networks, cellular networks, and public hot-spot WLANs. To bring this idealistic vision into... — Nancy Konish Partners Pursue Aerospace And Defense A few years ago, the semiconductor industry seemed to be fated for endless growth. Then the economy started to turn downward, leaving many companies struggling to find profits. For many wireless- and radio-frequency-focused companies, the world... — Nancy Konish DoD Prompts GPS Evolution In the past six months, global-positioning-system (GPS) equipment has garnered a lot of media attention over possible threats of enemy jamming. To defense-technology experts, however, this supposed security risk doesn't seem to be a cause for major... — Nancy Konish Photovoltaics Take The Weight Off Soldiers In the consumer world, smaller and lighter handheld devices are considered flashy and desirable. In the defense arena, however, it is critical rather than fashionable for a device to be small and low in weight. After all, soldiers must carry this... — Nancy Konish On The Wireless Front Syracuse, New York Anaren, Inc. recently announced that its Breakthrough 2003 launch represents a major improvement in balun transformers. This launch takes the form of a minuscule, surface-mount Xinger-brand... — Staff [Editor's Note] For The Big Picture, Look To Content I'm sure that you're all very aware that the wireless industry is no longer just about the handset. Even though this statement seems obvious, however, some people cannot alter their old perception. To me, saying that the industry is comprised solely... — Cheryl Ajluni |
