Critical Demands on Ruggedized Wireless Systems for Today and Tomorrow

August 2, 2010 12:57 pm | by Gregory Powers, Tyco Electronics | Comments

Wireless systems are now fully mainstream in our lives, not only in the consumer world of cell phones, Wi-Fi enabled laptops and satellite television, but also in the mission and life critical world of aerospace and defense. Recent applications such as ADS-B (Automatic Dependant Surveillance - Broadcast) managed commercial airline flight, software defined radios, and UAVs (unmanned aerial vehicles) bristling with sensors, all depend heavily on the electromagnetic spectrum to interact with the world, demand the highest in reliability, and are driving new and innovative solutions relative to electrical interconnect.

Will Telemedicine be the Next Killer App?

July 18, 2010 1:06 pm | Comments

At the American Telemedicine Association’s annual meeting recently the results of a national survey were revealed. The survey of health care and information technology professionals, sponsored by Intel, found that a majority of decision makers believe that the emergence of telehealth will have a major role in improving the care for the globally aging population, aka the “baby boomers.

Power Efficiency

July 15, 2010 12:06 pm | Comments

The path to achieving energy efficiency is ridden with obstacles. Q: If we continue to increase the power efficiency of a product, are we approaching the point of diminishing returns? Will it eventually detrimentally impact the cost of the product? Doug Bailey, VP marketing, Power Integrations This is an interesting question.

Wireless PC Peripherals Point the Way for RF Remote Control

July 8, 2010 1:02 pm | by Sveen-Tore Larsen, Nordic Semiconductor | Comments

Consumers are starting to complain about infrared (IR) remote control’s inability to cope with the demands of modern media devices. A recent study by Strategy Analytics1, for instance, found that while early adopters of advanced Internet TV services (such as AppleTV, Hulu, and AT&T U-Verse) value the ability to personalize and share their content, the adoption rate could be slowed because consumers “want better control devices and superior user experience”.

The RF Sting in the Digital Transmission Tail

July 8, 2010 12:38 pm | Comments

Simon Whittle, Nujira Ltd. The new generation of data-oriented digital communications networks being rolled out in the cellular, broadcast, military and other environments carries a sting in the tail for RF designers. In order to achieve high data rates, these new standards use advanced modulation techniques such as OFDM which significantly increase the variations in amplitude of the transmitted signal.
