Road warriors may no longer have to stay put in an airport lounge or Starbucks to access the high-speed Internet via an 802.11 Wi-Fi network. Thanks to software developed by two computer scientists at the University of California, San Diego, the time it takes to hand off from one Wi-Fi wireless network to the next can be dramatically shortened -- overcoming a major obstacle in Wi-Fi roaming.
Jacobs School of Engineering professor Stefan Savage and graduate student Ishwar Ramani have a patent pending on the basic invention behind SyncScan, a process to achieve practical, fast handoff for 802.11 infrastructure networks. Their study will be published in the Proceedings of the IEEE InfoCom 2005.
"Wi-Fi offers tremendous speeds if you stay in one place or at least within 100 meters of the same access point," said Savage, an assistant professor in the Computer Science and Engineering department and academic participant in the California Institute for

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
