Wireless USB

Short range wireless or personal area networking technology has grown rapidly in the past 5 years, mostly in the form of Bluetooth. While over a billion Bluetooth devices have been sold to date, there are a number of features that could enable new usage models that today's Bluetooth is not well equipped to handle. This talk describes Wireless USB, which is based on ultra wideband (UWB) radio technology. Wireless USB offers speeds of up to 480Mb/s at short distances, and energy efficiency far beyond Bluetooth. WUSB will allow exchange of large files such as digital photos, video, and music in seconds, not minutes, and will expend a fraction of the battery capacity compared to Wi-Fi or Bluetooth. The Wireless USB specification was ratified two years ago, and interoperability tests and certification are in the final stages. Products will begin appearing on retail shelves this summer. This talk will give a look "under the hood" of WUSB and UWB technology, and how it will impact computer, mobile, and consumer electronics products.
