Dadi Telecommunication Equipment GEA-8110A Gigabit Ethernet Analyzer is an integrated Ethernet Testing Tool for 10/100/100Mbps Ethernet Installation, Maintenance and Troubleshooting.
Network vendors in the performance monitoring and management solutions market are often daunted by the vast complexity of interprocess communications (IPC) and the need to scale with large network environments, running several applications simultaneously. Vendors with multiple management tools and data servers, and a separate solution for wireless performance of their networks will be hard pressed to focus on a unified holistic solution to manage the network services and applications proactively.
New analysis from Frost & Sullivan, World Network Performance Monitoring and Management Solutions Market for Enterprises, finds that the market earned revenues of $1.49 billion by the end of 2010. It market is expected to reach $3.37 billion at a compound annual growth rate (CAGR) of 12.3 percent from 2010 to 2017. (www.testandmeasurement.frost.com)
Washington, D.C. The Federal Communications Commission issued a Public Notice announcing that the Office of Engineering and Technology (OET) will commence a 45-day public trial of Spectrum Bridge Inc.’s TV band database system, beginning September 19, 2011.
Unused spectrum between TV stations–called white spaces–represents a valuable opportunity for our changing wireless mobile landscape. This block of spectrum is powerful platform for innovation and experimental use, holding rich potential for research and commercial purposes. The result of white spaces innovation has already led to a wave of new consumer technologies, including wi-fi and other innovations like baby monitors and cordless phones that have generated billions in economic growth.
In their paper, researchers described testing two versions of their battery supercapacitor hybrid. The first is a sandwich with nickel/tin anode, polyethylene oxide (PEO) electrolyte and polyaniline cathode layers; it was built as proof that lithium ions would move efficiently through the anode to the electrolyte and then to the supercapacitor-like cathode, which stores the ions in bulk and gives the device the ability to charge and discharge quickly. The second packs the same capabilities into a single nanowire. The researchers built centimeter-scale arrays containing thousands of nanowire devices, each about 150 nanometers wide. A nanometer is a billionth of a meter, thousands of times smaller than a human hair.
Ajayan’s team has been inching toward single-nanowire devices for years. The researchers first reported the creation of three-dimensional nanobatteries last December. In that project, they encased vertical arrays of nickel-tin nanowires in PMMA, a widely used polymer best known as Plexiglas, which served as an electrolyte and insulator. They grew the nanowires via electrodeposition in an anodized alumina template atop a copper substrate. They widened the template’s pores with a simple chemical etching technique that created a gap between the wires and the alumina, and then drop-coated PMMA to encase the wires in a smooth, consistent sheath. A chemical wash removed the template and left a forest of electrolyte-encased nanowires. In that battery, the encased nickel-tin was the anode, but the cathode had to be attached on the outside.
