Using advanced battery technologies to unlock the dynamic growth potential of remote wireless sensors used in "smart infrastructure" and related applications. By Sol Jacobs, Tadiran Batteries Contrary to all the recent economic news, the February 17, 2009 edition of The Wall Street Journal contained an upbeat article by Michael Totty entitled "Smart Roads.
By Todd Mersch, Continuous Computing So here we are in the second half of 2008 why are femtocells not more widely deployed in our homes? When are we finally going to get five bars in the family room? And what’s keeping us from quicker YouTube downloads in our kitchens? click to enlarge Figure 1.
The introduction of new radio technoloiges, like OFDM and MIMO, in LTE and WiMAX systems has created the need for new types of test equipment. George Reed, Azimuth Systems click to enlarge Figure 1. Three methods of testing transmitter and receiver performance: lab-based, direct cable connectivity, over-the-air testing and lab-based, connection through a channel emulator that simulates real world conditions.
By Danny Tseng, Cypress Semiconductor Designing a platform with modularity in mind is one approach that can shorten design time as well as enable easier feature upgrades. click to enlarge Figure 1. Architecture modularization of a mobile handset.
The recent advent of low-cost FPGAs equipped with high-performance transceivers and DSP blocks will greatly reduce the build and deployment costs of a video broadcast system. By Shakeel Peera, Lattice Semiconductor Corporation click to enlarge Figure 1.
Grounding and care in layout is the key to keeping noise out of the control circuit and allowing correct operation. Grounding and care in layout is the key to keeping noise out of the control circuit and allowing correct operation. By John Bottrill, Texas Instruments click to enlarge Figure 1.
A receiver's position accuracy is a fundamental challenge of satellite navigation system. As a result, GPS receiver designers must perform a combination of measurements to ensure the device will perform as expected. David A. Hall, National Instruments Geocaching involves discovering various "caches" whose coordinates can be found on the Web and whose contents are located all over the world.
Protecting infotainment dynamic data is essential. The unique advantage of F-RAM guarantees higher availability & performance. By Duncan Bennett, Ramtron International The use of non-volatile ferroelectric RAM (F-RAM) in automotive applications began with airbag applications. This type of safety critical application was click to enlarge Figure 1.
This is part two of a three part series. Read part one By Dr. Michael D. Foegelle, ETS-Lindgren; Kevin Li, Nokia Corp.; Andrew Pavacic, Paul Moller, Motorola, Inc. Defining the Grip An informal survey of advertised handsets on the market revealed that they could generally be separated into two categories by width.
A new modeling methodology combines FPGAs and detailed circuit-level modeling in a design-to-test flow. By Greg Jue and David Leiss, Agilent Technologies click to enlarge Figure 1. This high-level design flow begins with the design of key algorithms which can be quickly evaluated in simulation to verify system performance with just a handful of simulation blocks.
Emulating the way that the human hearing system characterizes and groups the audio stream into sound sources proves to be an extremely efficient and accurate way to suppress both stationary and non-stationary noise. By Lloyd Watts, Founder and CTO, Audience click to enlarge Figure 1a.
A standardized hand phantom used together with the SAM head phantom for radiated performance testing mirrors real-world use. Dr. Michael D. Foegelle, ETS-Lindgren, Kevin Li, Nokia Corp., Andrew Pavacic and Paul Moller, Motorola, Inc. Figure 1. The resulting kinematic CAD model.
As wireless standards continue to evolve, software-defined ?test systems will continue to evolve with them. By Luke Schreier, National Instruments As the proliferation of wireless standards continues, the idea of using software-defined measurement capability has become a necessity as opposed to a matter of click to enlarge Figure 1.
Testing LTE Design simulation can be useful in addressing LTE design and verification challenges but requires consideration in selecting the appropriate model abstraction for the given phase of the design cycle. By Greg Jue, Agilent Technologies Emerging standards such as 3GPP Long Term Evolution (LTE) present a number of design and verification challenges for system engineers.
Thorough and accurate Multimedia Messaging Service (MMS) testing is critical to the successful deployment of any mobile phone offering a MMS capability. By Scott Grimmett, Agilent Technologies Over the years, the mobile-phone usage model has changed quite dramatically. No longer is it used solely for its voice services.
For a US company intending to launch a worldwide product, compliance with EuP regulations will ensure entry to that market of almost 500 million people. Jeff Uden, Newark One of the most interesting trends in the electronics industry at the moment is the movement towards designing products in an environmentally friendly way.
By Gary Nevison, Newark Designers of electronic and electrical equipment are increasingly challenged to design new products that comply with legislation that applies in the markets where their products will be sold. As more US manufacturers sell their products internationally, design engineers not only need to consider legislation in the U.
By Gary Nevison, Newark Designers of electronic and electrical equipment are increasingly challenged to design new products that comply with legislation which applies in the markets where their products will be sold. Previously, we took a look at all the different flavors of RoHS.
