UWB test: Call for participation Blog 9/30/2007 Post a comment I'm happy to report that an unbiased performance test is being coordinated by industry expert Fanny Mlinarsky, a highly-regarded consultant with more than 24 years of senior R&D expertise in wireless technologies.
Designing RF remote controls for DTV products Design How-To 9/26/2007 Post a comment In the short history of television remote control units, several different schemes have been tried. Early examples from the 1950s used wires, a single beam of light and ultrasonic sound to change channels and control the volume. These have obvious limitations. For instance, the photoelectric cells in the light beam example couldn't tell the difference between a flash light, an ordinary table lamp or even sunlight. This could lead to some chaotic television viewing.
SerDes: A new definition? Blog 9/26/2007 Post a comment The mission of engineers is to find a better way and that might be what Align Engineering has done with its Align Lock Loop (ALL) technology.
Implementing solid security on a Bluetooth product Design How-To 9/25/2007 Post a comment The first section of this article outlines the security features of individual Bluetooth components, and the subsequent section drills-down into the application component explaining the various types of Bluetooth security breaches and recommended solutions to thwart them from the product application.
HD interface chipsets allow CE systems to connect wirelessly Product News 9/24/2007 Post a comment Check out these Wireless High-Definition Interface (WHDI) chipsets from Amimon, that make it possible for a wireless HD video connectivity net that allows consumer electronic devices to share HD content throughout the entire home, up to 30 meters (100 feet) through walls, while maintaining wire-equivalent quality with no latency.
Optical transceiver targets wireless base stations Product News 9/21/2007 Post a comment Designed to support standards for cellular, WiFI, and WiMAX networks, Avago's latest optical transceiver supports high speed serial links over multimode optical fiber at signaling rates up to 3.7-Gbits/s for wireless base station applications involving the OBSAI or CPRI protocols.
Ericsson modules challenge Qualcomm, WiMax Product News 9/19/2007 Post a comment Ericsson AB has developed its first module to bring high-speed cellular data to notebooks and other client devices, challenging a market where Qualcomm reigns and crossing swords at the Intel developer Forum with Intel which is promoting adoption of WiMax.
Radio Basics for RFID, Part 1 Design How-To 9/18/2007 1 comment While this book excerpt from The RF in RFID:Passive UHF RFID in Practice, focuses on RFID applications, it is an excellent primer for RF basics. This Part covers electromagnetic waves, signal voltage, and power.
Managing cost issues in the design of femtocell home base stations, Part 1 Design How-To 9/13/2007 Post a comment The femtocell today takes on the performance and reliability of a macro base station, while adopting the costs, ease-of-use, and flexibility of a handset. This scenario begs a number of questions: What kind of radio is needed to meet the industry's current- and future needs? What are its performance metrics? This article tackles this and other issues in femtocell base station design.
MathWorks launches RF Blockset 2 Product News 9/13/2007 Post a comment Designed to help engineers implement and verify commercial and defense wireless communication systems and associated semiconductors, the new version includes support for Agilent data file fomats.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
