7. Main Requirement • Locate and identify devices • within an area, • moving to another authorized area, • or “lost” • Over time (autonomy must last for months or years, no maintenance) • A device (com. +loc.+energy) is a small fraction of a $ Larry Taylor (Staccato), Jason Ellis (GA) Rouzet- STMicroelectronics

8. Package Tracking • Currently, mostly bar-codes are used, requiring visual contact with the tracked item, creating not only an accessibility issue but also consumes time. • Solving these issues is worth the added cost of a wireless-label (assuming a very low cost solution, e.g. sub $2). • UWB based identification could offer the advantages of: • Shorterreading time (a whole truck could be read in seconds) • No need for line of sight within a reasonable range • Automatic warning provided by the tracking system whenever a package is being loaded on a truck/container heading towards the wrong destination, or when a package is mistakenly offloaded • Locating a package within the truck/container/warehouse Larry Taylor (Staccato), Jason Ellis (GA) Eliezer- InfoRange

9. Is the Technology Ready? Present the Technological Options • Is Society Ready? Compile Product Requirements In parallel with IEEE 802.15.4a:Invitation to a High-Tech Child Safety Forum Developing Solutions with Key Support Assemble the Stakeholders in Child Safety, Crisis Response, & Wireless Communications Together Examine the Feasibility of a Child Safety Infrastructure • Government Agencies (NIST, FCC, DOJ, etc.) • Wireless Communications Developers • Children’s Clothing & Shoe Manufacturers • RF Tag Manufacturers & Distributors • Children’s & Parents Advocacy Groups • Security Monitoring Services • Mapping & Positioning Software & Services A High-Tech Child Safety Roundtable A One-Day Event on Wednesday, October 8th, 2003 George Washington University Grand Ballroom, Wash DC www.KidLocate.net Larry Taylor (Staccato), Jason Ellis (GA) Brooks- LB&A Consulting

10. Application Scenario (1 of 3) • Dad enters home • The human device (Dad’s watch) broadcasts Dad’s ID. • After ID authorized, Dad’s preferred devices (such as PC, Fax, Mailbox, Phone, TV, Homecare, Hot water supply system) get ready for operation • Dad is moving toward one of the rooms • With location awareness, devices near Dad are operating • For example: when Dad is entering the living room • Received mails are notified • Answering machine notifies received calls • Stock channel is turned ON Larry Taylor (Staccato), Jason Ellis (GA) Kim- Samsung

11. Workplace Productivity Applications • Better communications between distributed sites • Moving maps • Phone call forwarding • Asynchronous messaging • Sharing space more effectively • Low-overhead personalisation • Measurement of space utilisation • “Pay-as-you-go” billing for space • Recording activity in a corporate memory • “Who was at the meeting last week?” • Demand now: Multinationals implementing distributed workplace strategies Larry Taylor (Staccato), Jason Ellis (GA) Batty- Ubisense

12. Audio “Sweet Spot” Prime listening position for an audio system; the “best seat in the house.” The sweet spot is the listening position for which an audio system is optimized. Normally located halfway between the speakers and back 6 to 8 feet for a stereo audio system, the sweet spot is where optimal sound quality is encountered Larry Taylor (Staccato), Jason Ellis (GA) Yurdakul- Wisair

13. Communications and Networking • Routing • Replacing GPS-assisted routing • Low cost, low power • At the cost of processing • Indoor as well as outdoor • Center-location • Minimum link cost of a group (e.g. multicast, cluster) • Optimal tree or mesh network formation • Smart flooding (avoid redundant flooding) • MAC • Exposed terminal problem is solved Larry Taylor (Staccato), Jason Ellis (GA) Kwon- Samsung/CUNY

14. Digital Routing As the Fire Fighter traverses the floor plan his Motorola XTS 5000 Digital radio transmits a digital pulse signal displaying digital bread crumbs on the display map. Larry Taylor (Staccato), Jason Ellis (GA) Nowakowski- Chicago

15. Summary • Confirmed interest level to start Study Group • Identified many enhanced applications • Restate commitment of leadership slate • Chair: Larry Taylor (Staccato) • Vice Chair: Jason Ellis (General Atomics) • Technical Editor: TBD (TBD) • Secretary: TBD (TBD) Larry Taylor (Staccato), Jason Ellis (GA)

16. Purpose of SG • Expected output from Study Group activities • New applications identified from official CFA • High resolution location capability • Scalable data rate • Very (Ultra) Low power • Evolutionary requirements captured in technical requirements document • Location resolution • Data rates and range • Power consumption • PAR & 5C generated for Task Group Larry Taylor (Staccato), Jason Ellis (GA)
