December 14, 2010 9:06 am | Comments

By Byron Henderson, Mesh Dynamics Smart Grid networks are currently receiving tremendous government attention and funding. The US Department of Energy says the Smart Grid "would integrate advanced functions into the nation's electric grid to enhance reliability, efficiency, and security, and would also contribute to the climate change strategic goal of reducing carbon emissions.


Network Offloading is Vital - but is Wi-Fi Up to the Task?

December 14, 2010 8:40 am | Comments

By Malek Shahid, Senior Strategist, Wireless, Alcatel-Lucent By 2013, global mobile data traffic will exceed two terabytes a month1. Video streaming, social media applications and smartphone signaling are the chief culprits. This data tsunami will swamp mobile network architectures, and operators face the challenge of finding the right way to offload it.


LTE and the Role of Femtocells

December 14, 2010 8:30 am | Comments

By picoChip and Continuous Computing LTE is coming. It’s almost impossible now to pick up an article on network infrastructure without reading about it and how companies are working on towards the shift. The wireless networks in place today were primarily designed to support voice, a job that they actually do quite well and with plenty of capacity to spare.


Power Film Capacitors Enable Advancements in Hybrid Vehicles

December 8, 2010 11:11 am | by Chris Reynolds, AVX Corporation | Comments

Within the last few years, designers have established a solid powertrain foundation for hybrid vehicles (HEVs) and electric vehicles (EVs). All major auto manufactures see the hybrid and electric vehicle market as one continuing to enjoy steady growth. One major driving factor to the projected increased growth is the significant technology advances taking place that directly impact the HEV and EV power electronic systems.


Cars, Clouds, and Pockets: Connecting Vehicle Infotainment Systems to Mobile and Internet Services

December 8, 2010 10:11 am | Comments

By Kerry Johnson, QNX Software Systems Already, vehicle telematics services have been deployed in tens of millions of automobiles. Nonetheless, mobile services offered on smart phones and other consumer devices are growing at a far greater pace. A quick survey of these mobile services reveals that many offer significant utility to drivers or passengers; in fact, some are designed specifically for in-vehicle use.


Designing a Robust Failure Indicator

December 8, 2010 10:09 am | Comments

By Chris Keeser, Cypress Semiconductor Corp. The other day I was driving to the local dump to drop off a load of trash carefully stacked into the back of the family minivan. Suddenly I noticed that the “trunk open” light came on. I quickly pulled over just as the rear hatch popped all the way open and the van began to empty my garbage bags all over the road.


Leading the Way to Smarter Grids: 4G WiMAX for smart grid communications

December 6, 2010 3:17 pm | Comments

By Ashish Sharma, Alvarion Ltd. Imagine having the ability to unify all the communications needs for the smart grid via a single communication – be it distribution automation, concentrators, video surveillance, smart metering, mobile workforce, etc.

The future holds RFID Applications that go far beyond mere bar coding. The world will be a different place once readers and RFID tags are everywhere. Q: “What are some of the untapped applications for RFID that we may see in the foreseeable future?” By Victor Vega, Alien Technology UHF RFID has matured to a point where “it just works.


Give your Brain a Break Today

December 6, 2010 12:09 pm | Comments

There is a lively debate going on among scientists over whether technology’s influence on behavior and the brain is good or bad, and how significant it is. Scientists say juggling email, phone calls, and other incoming information can change how people think and behave.

MIMO Applications

November 11, 2010 11:01 am | Comments

Multiple antenna technology enables high capacity and high data rates. Q: Right now there is a limitation on data rate for each user. Can MUMIMO overcome these limitations and if so, how? J. McFarland, Chief Technology Officer for Atheros Communications The advent of Web-enabled phones has clearly pointed out that wireless carriers need more system capacity to meet the expectations of their users.


How Femtocells Are Playing a Critical Role in the Transition to 4G

November 10, 2010 9:41 am | Comments

By Joe Cozzarelli, ANADIGICS As mobile carriers and network operators transition to 4G service, they are faced with several challenges, including the massive amount of smartphones available in the market, the volume of data traffic per phone that is rising exponentially, and all the steps required to deploy and upgrade their network infrastructures.


e-MMC Based Embedded Memory Architectures in Mobile Phones

October 20, 2010 12:55 pm | by Scott Beekman, Toshiba America Electronic Components, Inc. | Comments

The growth of features available in mobile phones has both driven and been enabled by changes in NAND based memory architectures. As phone capabilities evolved, feature rich phones migrated from NOR-based solutions to NAND-based solutions. Today, with the growth of GB1 (Gigabyte) class phones, a variety of NAND-based architecture solutions are available with various tradeoffs to consider.


High Speed Differential Interfaces and the Need for Common Mode Filtering and Protection

September 29, 2010 12:18 pm | by Jonathan Harris, ON Semiconductor | Comments

In the operating environment seen by electronics today there are numerous sources of electromagnetic interference (EMI) and radio frequency interference (RFI). This is due in large part to the increased use of RF technology. These types of interference result in the need for common mode filtering in applications utilizing differential interfaces.


Design Considerations Using Lithium Polymer Batteries

August 31, 2010 4:43 pm | Comments

Dr. Robin Tichy, Micro Power Electronics Li-ion cells come in three basic form factors: cylindrical, prismatic (rectangular brick shape) and the flat Lithium polymer cells. Lithium polymer cells, sometimes called laminate cells, are available in custom footprint size. They can be very thin or quite large depending on their intended use.


Serial RapidIO Gen 2 in Next-Generation Wireless Base Stations

August 30, 2010 12:52 pm | by Stephane Gagnon, IDT | Comments

Third- and fourth-generation wireless base stations that use today’s most-common interface standards, such as WCDMA, TD-SCDMA, LTE, TD-LTE and Wimax, require a large amount of signal processing to keep up with the uplink and downlink bandwidth requirements.
