Wireless Power Technology Embraces User-friendly Features

October 12, 2012 6:54 am | Comments

Wireless charging technology has been recognized as a very attractive solution to a wide range of applications because it conveniently replaces power cords and charging cables. This emerging technology is being adopted for charging mobile phones and other handheld devices [1] . Several major mobile communication service providers in Japan, Korea and the United States offer smartphones readily equipped with wireless chargers.


What’s The Worst That Could Happen? RF Communication Disasters

October 10, 2012 5:19 am | Comments

The morning of December 4, 2011 began normally for the team of Air Force technicians. As they settled into their shift flying unmanned aircraft over Afghanistan, perhaps they chatted casually and swapped stories from the weekend. Very soon, however, their conversations were interrupted by shrill alarm sirens blaring from their control monitors.


Fundamentals of Battery Fuel-Gauging

October 9, 2012 11:36 am | by Karthik Kadirvel, Design Engineer, Texas Instruments | Comments

Personal battery-powered devices range from single-cell devices such as cell phones to multi-cell devices such as electric cars. Range anxiety is a common issue among all battery-operated electronics. Users are anxious if they can catch the end of the movie before the battery on their tablet runs out of charge, or if they can drive their electric car to the next charging station before they get stranded on the freeway.


Replicating Dynamic Field Environments in the Lab for More Effective Regression Testing

October 4, 2012 6:54 am | by Erik Org, Senior Marketing Manager, Azimuth Systems | Comments

In today’s complex wireless ecosystem, as our mobile devices have continued to evolve, users have come to expect continually improving functionality. Accordingly, chipset vendors, device and infrastructure OEMs, and carriers are challenged to keep up if not accelerate the pace of innovation while maintaining high product quality.


Outdoor Enclosures for Wireless Base Stations

October 2, 2012 10:42 am | by Jeffrey VanZwol, Marketing Advisor, Purcell Systems Inc. | Comments

As wireless operators continue to build out their infrastructure to support ever-increasing bandwidth requirements, one commonly overlooked aspect that has a significant impact on operational cost is enclosures and cabinets needed to house electronics.   Outdoor equipment enclosures enable wireless operators to save substantial time, labor, space, capital and operational expense as compared to prefabricated buildings and shelters, while meeting their exact needs for equipment mounting, thermal management, coaxial and fiber cable management, power and battery backup.


Mobile HD Video: What are my options?

October 2, 2012 8:28 am | by Graham LS Connolly, Member of Technical Staff, Fairchild Semiconductor | Comments

In today’s consumer products, USB and HDMI™ have become household names and are synonymous with ultra-portable connectivity and HD video. As technology has improved and as the consumer’s demands for more features, high definition (HD) video playback and social networking capability continues to grow then so has the challenge constantly increased to maintain the ultra slim form factor on mobile products that help us to stay connected with the world.


Emergence of Thinking Networks

October 2, 2012 7:41 am | by Mike Fahrion, director of product management, B&B Electronics | Comments

When examining Flame, the most sophisticated malware that has appeared to date, investigators discovered an interesting feature: Flame can steal and transmit data from computers that have no Internet connections. Flame does it by using unsuspecting humans for bi-directional data transport. Flame begins the process by copying itself to every digital storage device that it encounters, including USB sticks and external hard drives.


Making Moves and Harvesting Energy

October 1, 2012 12:24 pm | by Janine E. Mooney, Editor | Comments

Engineers are tossing the batteries and making advances to save wasted energy in more effective and realistic ways Today’s technology offers the OEM more cultivated and feasible power options for wireless networks and devices. Also known as “power harvesting” or “energy scavenging”, energy harvesting is when energy originates elsewhere, from an external source.


Implementing Self-Powered WSNs for Building Automation

By Tim Bradow, VP of Marketing, Infinite Power Solutions (IPS) Advanced solid-state batteries together with ambient energy harvesting provide a permanent eco-friendly power solution for deploying wireless sensor networks in Smart Buildings. Wireless Sensor Networks (WSNs) are self-organizing, self-healing networks of small sensor nodes and are positioned to transform a variety of industrial sensing applications, including building automation (occupancy detection, HVAC, lighting controls, etc.


Software Development Tools Optimize ZigBee Performance

September 24, 2012 8:04 am | Comments

By Anders Lundgren, IAR Systems As ZigBee gains traction in the home automation and light industrial arenas, the right development tools make the difference in power savings. The ZigBee wireless protocol has been around for a number of years, but is just beginning to make a significant impact on the market.


Designing a More Patient-Proof Battery Holder

September 21, 2012 10:58 am | by Tom Blaha, President, Memory Protection Devices | Comments

As more and more battery-powered medical devices get utilized in the home or get worn by the patient, it is becoming increasingly critical to make this equipment less susceptible to patient-error. An innovative battery holder technology makes battery replacement virtually fool-proof, providing added protection against incorrect battery replacement, which can jeopardize product safety and performance.


How Non-Line-of-Sight Backhaul Really Works

September 12, 2012 7:19 am | by Frank Rayal, Vice President of Product Management at BliNQ Networks | Comments

Ever wondered how non-line-of-sight (NLOS) backhaul really works? And how NLOS backhaul is different from Line-of-Sight (LOS) backhaul? I will explain the difference here and highlight some key issues that make a very big difference in the performance of NLOS systems. A fundamental practice in designing wireless systems is to understand the characteristics of the propagation channel and to design a system that takes advantage of such characteristics while mitigating for different impairments.


The New Smart Home is the Really Smart Home

September 10, 2012 7:14 am | by Cees Links, CEO of GreenPeak | Comments

The new Smart Home is much more than just the connected home – it is about a truly smart home that combines the best of the connected home, the new Internet of Things, as well as the Internet of Tiny Things, with the marketing and business platform provided by the world’s leading entertainment and service providers.

Some of you may have seen my blog back in February about the "12 Communication Trends for 2012."  Six months later, the cool thing is that this continues to be a very hot and relevant set of topics for just about anyone who wants to quickly get a perspective on the top communication trends and how to plan for them.


Wireless Pedestrian Detection Technology

September 7, 2012 5:22 am | by Janine E. Mooney, Editor | Comments

We’ve all been there – distracted while driving. Unfortunately for some, it can result in a horrible accident. Hitting another car, a tree, or even a pedestrian. General Motors is making moves to prevent these accidents, and I must admit – the technology is pretty cool (and you’ve probably heard of it).
