November 2004 - In This Issue [Cover Story] Higher-Bandwidth DSP Covers Asia's Telecom Market Few places have experienced the explosive wireless-telecommunication-network growth that has been seen in Asia. The demand for wireless devices and, more importantly, the networks that support them has been especially great in China. For instance,... — John Blyler [Design Application] Automatic Antenna Tuning Saves Power In recent years, the world has welcomed an increasing number of short-range, license-free wireless applications that operate in the Industrial Scientific Medical (ISM) band. Among these applications are keyless entry, tire-pressure monitoring, door... — Ferenc Mernyei RF And Digital Tests Unite Against BER In today's wireless-receiver architecture, an evolving trend places the digital-signal-processor (DSP) subsystem closer to the radio-frequency (RF) antenna. This trend highlights a need for innovative RF/digital-verification solutions. Many... — Scott Ferguson , et al. [New Products] 802.11a/b/g Solution Occupies Single Chip Although the evolution toward higher integration remains at a constant rate of improvement, such integration is only successful if it does not sacrifice performance. Atheros Communications, Inc. claims to have overcome that risk with its single-chip... — Nancy Friedrich DSP Goes From Algorithm To Implementation To implement algorithms, digital-signal-processing (DSP) developers have had to rely upon design flows that use manual approaches. Aside from being time consuming, the manual process can invite errors. To enable faster and more efficient DSP design... — Nancy Friedrich Interconnect Manages Power And Data Flow As systems-on-a-chip (SoCs) bring more functionality onto the chip itself, data flow becomes a daunting issue. To confront this design problem, Sonics, Inc. has come out with the SonicsMX solution. The goal of SonicsMX is to enable the design of... — Nancy Friedrich Real-Time Clock IC Cuts Current Consumption In handheld devices, energy efficiency is critical. To help designers achieve that efficiency, Seiko Instruments has come out with the S-35180A and S-35380A Series ICs. These ICs promise to provide ultra-low current consumption for real-time clocks.... — Nancy Friedrich [Column] Letters To The Editor EDUCATION IS NOT IMPOVERISHED I read your editorial, "We Are Fighting A Battle That We Dare Not Lose" (July/August 2004, p. 17). My comment is that you confuse increases in investment with actual... — WSD Readers WLAN Follows Ethernet Into Industrial Control To simplify life, we prefer to think of wireless and wired-Ethernet local-area networks as being two versions of the same thing. But these networks are inherently different. For instance, the configuration of wireless is totally unlike that of... — Rod Corder Bluetooth Will Answer The Call For CD-Quality Sound Currently, wireless audio applications are exploding through cell phones and digital music, MP3, and DVD players. This demand is being driven by consumers who are now very used to the CD quality of digital music players. Users realize that they can... — Jalil Shaikh [News] Single Chip Brings A-GPS To Mobile Phones When the Enhanced 911 (E911) mandate was put into place by the Federal Communications Commission (FCC), both carriers and device makers fought to cost effectively implement a service that seemed to offer little return on investment. Since that time,... — Nancy Friedrich Europe Invests In Micro And Nano Design For a long time, micro- and nanotechnology-based products only existed in the minds of engineering dreamers. Now, microtechnology products have evolved into physical entities. In the near future, products based on nanotechnology also will begin to... — Nancy Friedrich Standards Compete For Home Front Recently, the IEEE 802.11a and 802.11g standards have been gearing up to meet the wireless multimedia needs of the home. Yet these WLAN players may soon be facing stiff competition—especially when it comes to wireless video. In two recent... — Nancy Friedrich Short Clips Ember (www.ember.com) closed an additional $25 million in funding led by Vulcan Capital. Joining Vulcan in this latest round were three new strategic investors: ChevronTexaco Technology Ventures, Hitachi Ltd., and WestAM. Other... — Nancy Friedrich [Editor's Note] Wireless Rides The Cyclic Market Have you ever noticed that even though everything changes, the pattern of change seldom varies? Paradoxically, some things seem to be in constant flux while others seem to remain relatively unchanged. Take the technology markets, for instance.... — John Blyler [Around the World] Snapshots In a new funding round, Siemens Venture Capital (www.siemensventurecapital.com) increased its stake in the Berlin software company, space2go GmbH, by an unspecified amount. The new capital is intended to support the... — Nancy Friedrich France Sets Its Sights On RFID For many years, the French paid little attention to radio-frequency-identification (RFID) technologies. Now, tags and readers—high-tech bar-code systems—appear to be following the same arduous path as the Internet. Despite the fact that... — Thomas Forner [On The Wireless Front] On The Wireless Front San Jose, California Micrel, Inc. recently rolled out four high-performance, low-dropout (LDO) regulators in the industry's smallest plastic packaging: the 2-x-2 MLF. The MIC5219/47/52/55 series is part of... — Staff |
