  1. ULTRA-WIDE BAND:What is it? How can it be used? Presented by: Troy Hayes Kevin Koelbel Robert Stewart

  2. UWB: What is it? • New radio technology providing high speed data transfer • Classification of signals that spread over a large bandwidth, specifically those >500 MHz (A typical telephone modem operates at 12 kHz) • Short pulses of energy lasting nanoseconds, but bandwidth goes to very large levels • Transmits over a wider range of the radio spectrum than conventional wireless systems

  3. What is it? (cont’d) • Short range radio technology – transmits up to 30 feet • Composed of pulses of only a few cycles in length • Supports direct transmission of digital communication as a baseband signal • Information is not transmitted on a single pulse and the frequency of the signal is unable to be determined

  4. UWB: History • Originated in 1962 • Based on work in “time-domain” electromagnets • Invented by Dr. Gerald F. Ross • First patent awarded to Dr. Ross in 1973

  5. History (cont’d) • 1980’s – UWB was often referred to as “baseband,” “carrier-free,” or “impulse” • 1989 - The term “UWB” was first used by the U.S. Department of Defense • Prior to 1994 - most work in UWB was classified by the U.S. government • Since 1994 - UWB programs were declassified

  6. UWB: Advantages • Average transmitted power is low because of the duty cycle, which results in low power consumption • Higher data rates than conventional wireless technology • Less chance of interference than narrowband radio designs • UWB radars allow low probability of interception and detection, high data throughput, precise ranging and localization

  7. UWB: Disadvantages • Current FCC regulations limit UWB use to a range of 30 meters • Typically used indoors due to the limited range • Equipment not readily available to the general public yet • Although cheaper to operate, equipment is currently more expensive than conventional wireless equipment

  8. UWB: Uses • Personal Area Networks (PAN) • Local Area Networks (LAN) • “UWB Heart and Respiration Monitor,” and wireless patient location and tracking system (Wireless 2000Technologies) • Radar systems • Home entertainment centers • Remote tracking devices

  9. Uses (cont’d) • Transfer digital photos to a printer without a PC • Send movies / mp3’s from a laptop to a PDA • Play media on monitors / projectors across the room • Sync mobile phones and PCs • Sync laptop computers and PCs • Quickly back up PCs

  10. Educational Applications • Send large files to entire class • Quickly collect assignments • Create presentations with imbedded media • Show videos with less set-up time • Back-up and restore student files / equipment
