About This Report Ultrawideband (UWB) technology has the potential to enable a range of new applications. Imagine downloading a DVD-quality movie in the time you take to fill a car's gas tank. When you arrive home, that video may play back on any TV in your home as you move about—without requiring any new wiring between rooms. Has the computer ever seemed noisier than you'd like it to be? In the future, you may be able to locate the computer in a closet and use UWB to transmit the video to your desktop monitor. Heavy users of digital cameras and MP3 players lose patience sometimes at the amount of time necessary to move data between portable devices and a PC. With a wireless Universal Serial Bus (USB), you'll need less than 30 seconds to transfer the contents of a 1-gigabyte memory card—typically, enough for a vacation's worth of photos or more than 15 hours of music. Operating at some 480 megabits per second, Wireless USB will rely on UWB technology and will be in products available in 2006. If you've never heard of wireless USB before, expect to hear a lot about it from analysts and journalists during the next year. Within five years, Wireless USB will likely be as common as wired USB is today. Fast data rates may not be the only benefit of UWB. Relative to other wireless technologies, UWB can have superior ability to penetrate walls and human tissue. UWB's wall-penetrating ability makes possible the use of a type of active radio-frequency–identification tag—which people sometimes call UWB tags—to locate valuable assets, such as notebook PCs and video projectors, within a building. UWB's wall-penetrating ability may also enable portable radar devices for use by law-enforcement, military, and rescue personnel to detect people hidden in buildings or under rubble. UWB's ability to penetrate clothing and human tissue may make it possible for medical technicians to monitor physiological indicators such as heartbeat dynamics—without the patient's having to undress. This report is the first in a series that aims to provide guidance for technology suppliers who seek to understand how users will receive value from specific wireless innovations. These reports will briefly summarize technologies and company activities and provide detailed coverage of how users will take advantage of applications that are enabled by these technologies. We welcome feedback about this report and the program, and we encourage you to contact us with any questions or suggestions. For more information, contact Michael Gold at telephone:
