The sheer number of smart connected devices with data-intensive applications, such as high-definition video, has created an explosion in the demand for mobile broadband. This trend increasingly requires wireless infrastructure equipment manufacturers and wireless service providers to dramatically boost network performance.

Brainstorm: Wireless Power

February 19, 2013 4:39 pm | by WDD Staff | Comments

As our smart phones, tablets, and other wireless devices get smaller and smaller, this creates more challenges for the electronic designer.  And as we depend more on these devices, and give up our paper calendars, note pads, and other old fashioned ways of keeping track of our lives.


Turning Ideas Into Validated Products—Faster

February 15, 2013 4:46 pm | by Andy Botka, Agilent Technologies | Comments

For test equipment manufacturers and their customers, one trend is unavoidable: the deepening integration of the RF, microwave and high-speed digital technologies used inside today’s electronic systems, especially mobile devices. To satisfy end-user demand for always-on access and fast data rates, mobile devices need powerful processing capabilities.


What is the Real Smart Home?

February 15, 2013 3:52 pm | by Elly Schiatse, General Manager, GreenPeak Belgium | Comments

You are ready and packed to leave on a holiday trip and for the first time, you agreed that your teenage son can stay home alone. The control freak in you is already making long lists of daily and weekly tasks and to-do’s to keep the pets and plants alive, and the calamity predictor in you wants to anticipate for flooded bathrooms and burning fryers.


Wireless Communication Systems Using Phased Array Antennas

February 14, 2013 3:31 pm | by Dr. John Howard, President & CEO of Electromagnetic Technologies Industries, Inc. (ETI) | Comments

There are many factors that contribute to the limitations of wireless systems, of which arguably the most important are frequency bandwidth (spectrum availability) and frequency efficiency.  Though efficiency may be increased by higher modulation rates, more sensitive receivers and more accurate bit error detection/correction methods...

Monetizing LTE Investments: Dynamic Policy Management

February 14, 2013 11:37 am | by Graham Kunz, Product Marketing Manager, Empirix | Comments

LTE is no longer the future of telecommunications; it is now a key component of the network’s infrastructure. Service providers are investing heavily in this technology to meet customer demand as consumers continue to purchase smart phones, tablets and other wireless devices at unprecedented rates.


Transmitter Measurements on Multistandard Base Stations

February 12, 2013 2:11 pm | by Martin Schmähling, Spectrum Analysis Product Manager, Rohde & Schwarz | Comments

Following its introduction 20 years ago, GSM has established itself as the de facto global standard for mobile telephony. Since this time, wireless communications has continued to develop. Whereas GSM was initially only designed for voice, the GPRS and EDGE extensions have also made it usable for data services.


Components, Characteristics and Device Implementation

February 12, 2013 10:24 am | by Luis Puebla, Applications Engineer, Freescale | Comments

According to the National Sleep Foundation, more than 18 million American adults have obstructive sleep apnea (OSA). OSA occurs when the back muscles of the throat relax while sleeping, causing the airway to narrow, resulting in snoring. These muscles could also completely block the flow of air to the lungs.


Proper Data Security

February 12, 2013 9:37 am | by Dean Wiech, Managing Director at Tools4ever | Comments

There are really three sides to proper data security. The first step is ensuring that new employee accounts are created with the proper access rights when an employee joins the organization. The second is making sure those access rights remain accurate during the employee’s tenure, and the third is revoking all access rights when the employee leaves.


TD-LTE – A Global Standard

February 11, 2013 2:09 pm | by Stephen Hire, General Manager for India, Aeroflex Limited | Comments

The “TD” (Time Domain) flavor of LTE can no longer be viewed as a niche technology exclusive to China. Other countries worldwide, including India and Sweden, are embracing TD-LTE for their broadband wireless access rollouts. Before long, close to half the world’s population will be within reach of a TD-LTE network. India will have a full commercial service ahead of its northern neighbour, China.

Moore’s Law Meets RF

February 8, 2013 9:09 am | by Bill Driver, National Instruments | Comments

The byproducts of Moore’s law have increased the performance and reduced the cost of electronic products across every industry for more than half a century.  The development pace and proliferation of mobile devices today have leveraged Moore’s law, growing at a projected 24.9% CAGR for 2011 – 2017 (, May 3, 2012).

Smartphones, Tablets Help UW Researchers Improve Storm Forecasts

February 7, 2013 9:49 am | by Hannah Hickey, University of Washington | Comments

The next advance in weather forecasting may not come from a new satellite or supercomputer, but from a device in your pocket. University of Washington atmospheric scientists are using pressure sensors included in the newest smartphones to develop better weather forecasting techniques.


Optimizing Real-Time Application Software for Small Cells

February 1, 2013 4:06 pm | by Sridhar K V, Radisys | Comments

Operators are looking to deploy small cell technologies as quickly as possible to generate revenue, offload data traffic, and leverage the existing macro network efficiency. These small portable platforms have limited hardware, memory, and CPU speed so operators need real-time application software to manage their performance, stability, scalability, and efficiency to ensure customer satisfaction.


System-Level Design and Verification of Wireless Embedded System to Meet Global Demands Using a Mixed Domain Oscilloscope

January 10, 2013 3:16 pm | by Faride Akretch, Technical Marketing Manager, Tektronix | Comments

Designing and implementing wireless systems so they can be used in different geographic regions around the world represents a significant challenge. Wouldn’t it be nice if everyone all agreed on the use of frequency, modulation type, power levels, and bandwidth?
