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

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
• Shorter reading 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/ware
  house

Application Scenario (1 of 3)

• Dad enters home
• The human device (Dads watch) broadcasts Dads
  ID.
• After ID authorized, Dads 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

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

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

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
