The Path To 4G Will Take Many Turns A race is going on right now and it's a heated one. It's a race to the next generation of untethered communications—4G mobile broadband wireless. The prize for reaching the finish line first or even finishing at all could be huge. Yet that finish line keeps moving, as the fourth generation (4G) isn't yet fully defined. In fact, spectrum won't be allocated until 2007. Standards probably won't be complete until the year after that. Right now, though, many teams across the globe are... — Noah Schmitz March 2005 [Design Application] Metrics And Methods Bring VoWLAN Success Mobile phones have been a runaway success for two decades. Over the years, however, the cellular market has stabilized. Can Wi-Fi give the cell-phone industry a boost? The IEEE 802.11-based Wi-Fi data-networking technology has penetrated the small-office/home-office (SOHO) market. Now, it is expanding rapidly into the enterprise and public-access markets. Wi-Fi is well suited to carry packetized voice, such as Voice over IP. It also can offer cellular users better indoor coverage at a... — Fanny Mlinarsky February 2005 [Design Application] WLAN Testing Relies On Controlled RF The wireless enterprise environment operates under very different conditions than wired networks. As a result, this environment requires a fresh outlook on testing. For wireless LANs (WLANs) to succeed in the enterprise, developers must rely on system-level test solutions. Such solutions must produce repeatable outcomes, scale beyond a single device to a network, and provide systems designers with an automated solution that will decrease the cost per test. As discussed last month... — Graham Celine February 2005 [New Products] Wi-Fi Test System Evaluates Networks Although Wi-Fi networks are increasingly being adopted by consumers and enterprises, ways to test these networks are still emerging. An example is CMC's EE-WPA multi-station test system. Using this system, designers, test managers, and network engineers gain the ability to perform sophisticated capacity, scalability, and load stress testing on WPA-enabled enterprise-class products and wireless networks. The system is for WPA-Enterprise with full support for 802.1x authentication, RADIUS,... — Staff January 2005 [Design Application] Effective WLAN Testing Begins To Emerge Wireless-local-area-network (WLAN) technology first became prevalent in the small-office/home-office (SOHO) market. In that forgiving environment, convenience often outweighs performance concerns. But as 802.11 technology extends to the enterprise, wireless-system designers and developers must face the enterprise market's performance-based realities. Enterprise WLAN networks are evolving to support business-critical data and voice applications, large numbers of network users, and diverse... — Graham Celine , et al. November 2004 [Design Application] 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. October 2004 [New Products] Portable Test Solution Covers Up To 7 GHz Increasingly, outdoor base-station construction and maintenance demand the use of handheld spectrum analyzers. Yet those handhelds have been limited in frequency range. As a result, they require additional converters. Traditionally, these handheld... — Nancy Friedrich September 2004 [New Products] One-Box Tester Supports Multiple Standards Until now, no technology has successfully measured both WLAN 802.11a/b/g and Bluetooth modules from a single platform. Agilent Technologies, Inc. recently changed that trend with its N4010A one-box test set. This product replaces the golden radio... — Staff June 2004 [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 May 2004 [Cover Story] WLAN Testing Gets Down To A Science When engineers think of wireless-local-area-network (WLAN) test equipment, images of bulky spectrum analyzers often come to mind. They may even picture oddly named "sniffer" programs that are used in conjunction with these analyzers. In addition,... — John Blyler May 2004 [New Products] CDMA2000 Gears Up For Performance Test Run Protocols like CDMA2000 herald the long-awaited arrival of third-generation (3G) mobile services. As such services are rolled out, however, equipment manufacturers and service providers need to be absolutely sure that their new technologies work.... — Staff April 2004 [News] Sweden Becomes Global 3G Test Center Sweden has been at the forefront of wireless technologies for some time. Now, the country is opening its doors to U.S. and international companies that want to test their 3G-related technologies, products, and services. Sweden boasts virtually... — Nancy Friedrich April 2004 [News] Test Sets Gain Bluetooth Approval Test instrumentation must constantly validate itself against changing standards. Such validation is crucial to developers, who want to be confident in their products before submitting them for qualification testing. For developers in the Bluetooth... — Nancy Friedrich April 2004 [New Products] Get 802.11a/b/g System Testing Done By One Unit As the technology that supports wireless-local-area networks (WLANs) matures, so does the need for comprehensive testing. Multi-standard products based upon 802.11a, b, and g require measurement systems that can test all of the protocol variations.... — John Blyler March 2004 [Design Application] Test Sets Refine Handset Entertainment Wireless entertainment may soon lead to an upswing in the telecommunications market. In large part, its commercial success will depend upon the quality and usability of new mobile terminals. To run increasingly sophisticated games and other... — Jan Schiefer March 2004 [Product Features] RFIC Test System Meets Wireless Needs For one of the hottest growth areas in the semiconductor market, look to radio-frequency integrated circuits (RFICs). These ICs are an essential part of any wireless device—be it a cell phone, laptop, or multimedia product. To ensure that they... — John Blyler March 2004 [New Products] Spectrum Analyzer Endures Harsh Conditions To successfully install, maintain, and troubleshoot wireless systems, technicians must quickly find, identify, and solve problems. Because this work takes place in the field, the technicians require both performance and ruggedness. Anritsu claims to... — Nancy Friedrich February 2004 [Show Coverage] RF Probe Makes High-Frequency Testing Easier Wireless systems continue to migrate to higher and higher frequency bands. They hope to utilize uncrowned spectrums and larger data bandwidths. When it comes to testing, however, these increasingly high-frequency product components require very... — John Blyler February 2004 [Show Coverage] DUC And Enhanced FEC Arrive At The FPGA Core As major analysts predicted, FPGAs are continuing to expand into traditional ASIC and DSP markets. To take advantage of this growth, Xilinx is now offering a digital-upconverter (DUC) LogicCore module along with enhanced forward-error-correction... — John Blyler November/December 2003 [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  prev. page
