Power/Performance Bits: Aug. 23

Connecting implanted devices University of Washington researchers developed a new method for communication between devices such as brain implants, contact lenses, credit cards and smaller wearable electronics with other devices such as smartphones and watches. Using only reflections, an interscatter system requires no specialized equipment, relying solely on mobile devices to generate Wi-... » read more

Power/Performance Bits: March 1

Low power Wi-Fi Computer scientists and electrical engineers from the University of Washington came up with a way to generate Wi-Fi transmissions using 10,000 times less power than conventional methods and which consumes 1,000 times less power than existing energy-efficient wireless communication platforms such as Bluetooth Low Energy and Zigbee. The system, Passive Wi-Fi, uses backscatte... » read more

Super Wi-Fi For The IoE

From time to time the term “white space” may have popped up in wireless spectrum discussions. Generally, white space describes parts of the licensed radio spectrum that are unassigned, unused, only used part time by the licensees, or not used by them in certain geographic locations. Virtually every country in the world has some of this. Most of this exists in the television spectrum, and is... » read more

802.XX And The IoE

Ever since the first 802.11 standard was published in 1997, it has evolved to become the de facto protocol for much of the wireless networking across a wide range of devices and implementations. Today the protocol family includes 802.b 802.11a, 802.11g, 802.11n, and 802.11ac, respectively. Some of these will play a very important role in the IoE. There are other 802.xx protocols (such as 802.15... » read more

System Bits: Oct. 22

Untangled nanotubes Carbon nanotubes are lightweight, strong and conduct electricity, which make them ideal components in new electronics devices, such as tablet computers and touchscreen phones, but cannot be used without being separated out from their natural tangled state. Researchers from Imperial College London have developed a way to unravel and apply carbon nanotubes in the laboratory a... » read more

Following The WLAN Alphabet To Lower Power

By Cheryl Ajluni The quest for low power in electronic devices is one that shows no sign of abating any time soon. Pressure for it comes from many different sources, such as the continual drive to pack more functionality into ever smaller, mobile electronic devices. To try and maintain a decent battery life for today’s power-hungry “road-warriors,” engineers have to reduce power con... » read more
