November/December 2003 - In This Issue [Cover Story] Radio-On-A-Chip Unwires Electronics Many of today's engineers and designers hope to make the switch from wired electronics to their wireless counterparts. Factoring in installation, this migration typically provides a great deal of cost savings. But the adoption of wireless technology... — Cheryl Ajluni [Design Application] Java Security Guards Embedded Networks From the beginning, the Java programming language was designed with security in mind. Yet developers remained suspicious about its secure nature. They were blinded by the novelty of a portable language that could transfer applications from system to... — Prithvi Rao Wireless Security Re-Invents Itself Again The face of computing is being changed by innovations in wireless technology. For example, users are no longer bound to the traditional "wires" that made up their computing environment. Thanks to technologies like Wireless Local Area Networks (WLANs),... — Victor Chang Slice And Dice Chunks Of Radio Spectrum The path to real-time wideband channelization is camouflaged by different techniques. Among the competing approaches are Pipelined FFT, polyphase DFTs, multiple digital downconverters (DDCs), and both the Pipelined Frequency Transform (PFT) and its... — John Lillington Voice-Based Networks Fail Broadband Needs Existing wireless cellular networks were designed to transmit circuit-based voice signals across the air. This task is a very different undertaking than transmitting data or packet-switched information. Third-generation (3G) operators and vendors must... — Ronny Haraldsvik [Product Features] Design-For-Test System Fits Desktop Wireless designers are very well acquainted with time-to-market pressures. In hopes of escaping this familiar tension, they warmly welcome anything that can reduce these pressures—especially if it also lowers product-development costs. Among the... — John Blyler C Synthesis Nurtures FPGA Development The design starts that use reconfigurable processors—namely field-programmable gate arrays (FPGAs)—continue to grow in popularity. In fact, a recent Gartner Dataquest study found that FPGAs and application-specific signal processors (ASSPs)... — John Blyler [New Products] Reliable Board-To-Board Connections Are Forged Board-to-board interconnections are commonly made by traditional mechanical stacking connectors. Unfortunately, this approach invites modification costs and concerns. To eliminate these issues, Tyco Electronics Elastomeric Technologies spawned the... — Staff Voltage-Controlled Oscillators Are Reborn Although the industry tends to spotlight the newest innovations, many components and technologies continuously do an impressive job of reinventing themselves. For example, take voltage-controlled oscillators (VCOs). Their target applications have... — Staff 100% CMOS Satellite Radio Tuner Saves Space Over the next several years, forecasts predict that consumers will increasingly embrace satellite radios. To help prepare the radios for such popularity, Silicon Laboratories, Inc. has announced the Si2210 IC. This all-CMOS satellite radio tuner... — Staff [Column] Dataconverters Turn To Analog Synthesis Wireless applications increasingly depend upon digital-signal-processing techniques. In a transmitter, for example, they modulate information from a baseband onto an RF signal. In a receiver, they modulate information back to the baseband. This... — Eric Soenen Balance Hacker Crime And Punishment Is it really in society's best interest to impose severe punishment on young hackers? This question came about after the recent arrest of Jeffrey Lee Parsons. He is the teenager who wrote the variant of the Blaster worm that brought down thousands of... — John Blyler T1 Platforms Help Wireless Carriers Face E-911 Mandates Doing more with less has become a fact of life in today's economy. For the wireless carrier, this order can be tough to fill. It's especially hard to do when changes in regulations mean extra services, such as Enhanced 911 (E-911). To make matters... — Brian Sherk [News] Applications Bridge Mobile And Personal-Computing Environments Although some applications have garnered great consumer interest, not one has succeeded in dragging the industry out of its doldrums. Part of the problem may be that designers have confined their projects too much to their own industry segments. A... — Nancy Friedrich Processor Generation Promises Multimedia Greatness The ability to snap photos, play games, and listen to music has become a huge selling point for handhelds. Yet today's discerning wireless consumers are already looking for better multimedia performance. The great leaps and bounds of the wireless... — Nancy Friedrich Short Clips As its new CEO, Voice Signal Tech-nologies (www.voicesignal.com) named Richard J. Geruson. Previously, Geruson was a Senior VP for Nokia. He will take over responsibility for Voice Signal's day-to-day operations from the company's co-founder... — Nancy Friedrich Alloy Lures Handhelds With Conductivity The birth of new devices and the desire for miniaturization are rapidly raising power requirements. At the same time, the industry must maintain mechanical performance characteristics while lowering thermal resistance. Brush Wellman, Inc.... — Nancy Friedrich Designers' Guide Homes In On Printed-Circuit Boards An overwhelming amount of information can be covered in the area of high-speed printed-circuit-board (PCB) design and manufacturing. To approach this topic, for example, one recent book merges 10 years of course instruction, 30 years of experience,... — John Blyler [Editor's Note] The New Year Rings In Better Coverage We've just about come to the end of another year. As the old saying goes, it's time to go "out with the old and in with the new." To us at Wireless Systems Design, that means that it's time to add some new editorial features. We've created a... — Cheryl Ajluni [Around the World] Europe Offers Lessons On Giving Subscribers What They Want For years, developers worldwide have toiled to realize a seemingly simple dream: to deliver the Web anytime and anywhere. Yet recent history is rife with examples of applications that have failed to fulfill this dream. Connected PDAs, WAP-enabled... — Jonathan Sheena Snapshots Astec Power (www.astecpower.com) is moving its design facility in Pasig Kapitolyo, Philippines, to the Eastwood City CyberPark in Quezon City. Situated on the northeastern side of metro Manila, Astec's new leased facility will encompass... — Nancy Friedrich [Special Section] Wireless Gadgets From an economic perspective, things have certainly been tumultuous for the wireless industry. Yet those setbacks fail to slow the steady stream of innovative products and development. Just look at this holiday gadget section. We've included some... — Staff Wireless Networking Comes Home We've all been exposed to the benefits of wireless technology in one form or another. In our personal lives, we rely heavily on cell phones. To make us more productive in our professional lives, we use devices like PDAs and PCs. In those capacities,... — Staff TiVo-Like Device Plots A PC Takeover Not all that long ago, TiVo was the "must-have" gadget for television fans everywhere. Although it's a pretty slick device, TiVo's price tag and monthly subscription fee left many consumers unwilling to make the investment. Now, another option has... — Staff Picture Frame Displays Multitude Of Images Do you know any wireless enthusiasts who are enamored with digital photography?
