The Emerging Smart Multi-Grid™ Wireless Architecture – A Network of Networks 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.
Model-Based Design for Hybrid Electric Vehicle Systems Energy security, fuel prices, and environmental concerns have increased pressure on the automotive industry to create energy-efficient and environment-friendly vehicle designs. Research in the last decade and a half has led to a range of vehicle designs based on electric drives.
Enhanced RFCMOS Paves the Way for UWB Systems Ultra Wideband (UWB) wireless systems are capable of delivering extremely high data rates with little interference and excellent frequency diversity. These transmission properties allow high performance systems to be designed at frequencies that can be implemented using enhanced RFCMOS IC technologies.
Software Defined Radio for Wireless Devices Wireless in the commercial world started in the late 1980s with the advent of car-phones and 2 lb. handsets that cost more than $2000. The first problem that the industry needed to solve was that of reducing size and cost in order to make the handset a portable and mass-market device. This problem has mostly been solved; we now have phones that barely weigh a couple of ounces and cost less than $40. The next challenge for the industry was to evolve the handset from a purely voice communications device to a multifunction device that is capable of handling data, video, music, and graphics as comfortably as voice.
N.C. Hospital Looks to RFID Technology to Improve Asset Visibility Southeastern Regional Medical Center (SRMC) in Lumberton, N.C., has contracted RadarFind to install an asset-tracking system that uses active RFID tags and interrogators operating in the 902 to 928 MHz range.
