February 01, 2004 - In This Issue [Cover Story] Transceivers Make Wireless Easy The desire for wireless embedded communications is quickly gaining ground. After all, wireless technology gives users unrestricted access to different locations. At the same time, it eliminates the need for costly wiring. Consider, for example, a... — Cheryl Ajluni [Design Application] Technology Advances WLAN Implementations More options are available to developers of 802.11 wireless-local-area-networking (WLAN) products than ever before. To support a growing number of coding schemes and data rates, industry-standards bodies continue to establish new specifications.... — Jeffrey Feigin CTCSS Unclutters Receiver Sound To allow multiple users to share one carrier frequency, many handheld transceivers employ Continuous Tone Coded Squelch System (CTCSS) encoders and decoders. CTCSS systems add a tone at the low end of what the human ear can hear to a transmitted... — Jeff Dahlin UWB's Promises Hold Industry-Wide Appeal Ultra Wideband (UWB) is one of the latest radio-frequency device technologies to hit the news. Yet a number of people are still unaware of what sets this technology apart. To send information through the air over short distances, UWB uses the... — William Stumpf [Product Features] Wireless-Data Demands Force Memory's Rebirth With the number of features in next-generation handsets on the rise, the adoption rate of data-based capabilities is surging. In the handset itself, this trend poses a significant strain for both code execution and data storage. To take some of the... — Cheryl Ajluni [New Products] USB-Port Connections Slash Number Of I/Os Wireless-device designers constantly operate under the mantra of "smaller, faster, lighter, and better." The parts that go into a handheld must therefore follow the same path of constant improvement. An example is the NLAS2066 from ON Semiconductor.... — Nancy Friedrich Mobile-Design Solution Fills Development Needs It seems that the creation of mobile-computing devices may have just gotten easier. In part, the credit for this improvement should go to the new Metrowerks OpenPDA platform and CodeWarrior for OpenPDA Application Development Tools. The OpenPDA... — Nancy Friedrich Flash Raises Memory-Subsystem Throughput In the memory arena, various technologies and architectures have set their sights on handhelds. Among the latest competitors is a 64-Mb Flash-memory device that boasts high performance. The MT28F644W18, which is sampling from Micron Technology, was... — Nancy Friedrich [Column] Verification Tools Expand To Cover The ESL Space The need for verification has become a driving force behind the resurgence of electronic-system-level (ESL) development tools. Previously, ESL tools claimed to enable accurate chip design above the register-transfer level (RTL). Today, however,... — John Blyler Satellites Promise To Reliably Transport IP-Based SS7 Increasingly, cellular carriers and service providers are using IP networks to transport and route Signaling System 7 (SS7) traffic. The SS7 protocol boasts a mechanism for offloading the traditional public-switched-telephone-network (PSTN)... — Jason Lawlor [News] Protect Your Wi-Fi Networks As 802.11-enabled products multiply, the challenges of securing wireless-local-area networks (WLANs) in the home and office will continue to grow. But the biggest security threat doesn't actually come from attackers. It comes from users who lack the... — John Blyler Short Clips The shareholders of Mimix Broadband, Inc. (www.mimixbroadband.com) elected Erik van der Kaay to its Board of Directors. Currently, van der Kaay sits on the boards of RF Micro Devices, TranSwitch Corp., and COMARCO, Inc. Mimix also closed its... — Nancy Friedrich Wireless-Monitoring Solution Guards Ports Today, a great deal of media attention is focused on the vulnerability of U.S. ports. Aside from a lack of personnel and financial resources, the port authorities are faced with a huge number of containers to inspect. Thankfully, it appears that... — Nancy Friedrich Football Fans Shell Out RFID Payments Radio-frequency-identification (RFID) technologies have altered the course of numerous industries, including automotive, retail, and manufacturing. Now, RFID is finding ways to improve consumers' lives as well. In Seattle, Wash., for example, an... — Nancy Friedrich Rugged Antenna Outfits Trucks Commercial telematics is a rapidly growing market segment. After all, solutions like asset tracking and data applications are mostly utilized by commercial vehicles. Yet those vehicles come with their own set of needs. For example, they must... — Nancy Friedrich Wi-Fi Passes Space Evaluation Recently, Wi-Fi networks have been popping up in more and more places. From airports and coffee shops, they've made their way into bookstores, fast-food restaurants, and more. As prevalent as these networks are becoming, however, they seemed fated... — Nancy Friedrich Cars Receive Satellite TV A few years ago, a debate raged over whether or not telematics applications would really take off. Now, it's hard to judge where they'll stop. Viewing screens and DVD players are already showing up in a lot of vehicles. One company is even promising... — Nancy Friedrich [Show Coverage] Chip Enables Wireless-Internet Phone Design Since the early 1990s, telephone calls over the Internet have grown increasingly popular. Often, such calls are referred to as voice over Internet protocol (VoIP) or IP telephony. As old public-branch-exchange (PBX) systems are phased out, the rise... — John Blyler The Future Of Wireless Is On Display At Wireless Systems 2004 The Wireless Systems 2004 Conference and Exhibition is right around the corner. From March 8 through 10, it will be held at the San Diego Convention Center in San Diego, Calif. This year, the show will testify to the robust nature of the wireless... — Cheryl Ajluni Electromagnetic Software Eases Design The successful analysis of high-frequency electromagnetic (EM) circuits is critical to a whole host of wireless applications. Such analysis is needed for the design of microstrip and stripline circuits, planar spiral inductors, RFIC and MMIC... — John Blyler Desktop Antenna Extends Wireless-Network Range Many users have felt frustrated by the limited range of their 2.4-GHz 802.11 wireless-local-area-network (WLAN) access points and bridges. Luckily, improvement options have begun to appear. Users could, for example, install a higher-gain antenna... — John Blyler RF Transceiver Makes Zigbee-Product Entrance Interest is steadily building around the new low-data-rate wireless standard known as IEEE 802.15.4.
