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

3. 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

4. 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

5. 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

6. 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

7. 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

8. 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

9. 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

10. 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

11. 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
