    dont know their own location
  • Unlike the Movies, structural fires are
    characterized by heavy smoke and darkness
  • Sounds are diffused by smoke and difficult to
  • Seconds count...
  • If they are known to be on the scene (sometimes
    they are not), it may take a long time before a
    firefighter is missed
  • Commanders dont know status of their
    firefighters (oxygen level, health, etc.)

  • Locate and identify devices/people within an area
  • Communicate sensor information
  • Over time (autonomy must last for months, devices
    can be re-energized)
  • A device (com. is some , can be
    much more with certain kinds of sensors
  • Example
  • For tracking and safety purposes in large
    communities environments such as schools and
    hospitals (large range, medium or large
  • For preventive medicine , health monitoring and
    health therapy purposes. Typically Body Area

Rouzet- STMicroelectronics
Properties (1 of 2) (for next slides, features
are mainly extracted from application 1 which is
the highest demanding )
  • Thousands of active devices may exist in one area
  • Devices are as simple as possible (no processor
    inside, could even be deaf?)
  • Communication is at very low data rate (Kbps?)
  • Communication is uncoordinated (sporadic or with
    low periodicity)
  • Network is adhoc. A controller node exists and
    concentrates the intelligence
  • Devices are mainly sleeping (powerful power save
  • Devices can be located easily (see next slide)
  • Reliability of transmission is essential

Rouzet- STMicroelectronics
Properties (2 of 2)
  • Localization
  • Must be offered at very low cost (no specific
    sensor ? UWB is a very good candidate
  • Must be done thanks to a simple exchange protocol
    using only local time of devices and normal
    precision clocks
  • Required precision is some 10s of cm or 1 m
  • Good time resolution in the system ? UWB
  • Devices can move (10-20 mph)

Rouzet- STMicroelectronics
  • The system can be operated in open environments
  • (outdoor)
  • A frequency band must exist ? UWB, possibly with
  • The population density can be huge ? very low TX
    level, very low duty cycle factor, possibly
    mechanisms to spread the emission over the full
    band for a given population in one large area
  • using and overcrowding the ISM bands does not
    appear as a good choice

Rouzet- STMicroelectronics
  • Fraction of a , autonomous (battery powered) for
    months ?
  • CMOS !
  • No processing needs
  • No initial set up
  • No big precision oscillator
  • Good realistic examples are chips for smart cards
    ? same objectives (Quantity, cost,
    manufacturability, ) but with antenna and
    battery included

Contribution 10Oren Eliezer
Package Tracking
  • Currently, mostly bar-codes are used, requiring
    visual contact with the tracked item, creating
    not only an accessibility issue but also consumes
  • 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
  • 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
  • Locating a package within the truck/container/ware

Eliezer- InfoRange
Shipment and Delivery Applications - Comparison
with Asset Management
  • Similar to the asset management applications in
    some requirements
  • More sensitive to cost of wireless label to be
    attached to each packet/item to be tracked
  • Higher volumes (the labels are a lot more
    temporary compared to those of asset management,
    and are attached to many more items)
  • Higher aggregate bit-rates needed (e.g. full
    truckload of packages to be scanned/read within

reader (fixed or portable)
multiple packages/items (e.g. 1000)
Eliezer- InfoRange
Discussion of Transmission only Devices
  • With a low level of transmission assumed (e.g.
    below 1mW), the receiver may consume more than
    the transmitter.
  • If a wireless label is to be implemented as a
    transponder that would transmit its message only
    in response to being polled, then it might have
    to waste more energy in reception than in getting
    its message through (receiver not only consumes
    more but is powered on for longer intervals).
  • Since power consumption should be minimized, and
    periodically powering a receiver could be
    wasteful, transmission only devices should be
  • If a devices message comprises very little data,
    and the air-occupancy and spectrum of the
    transmission allow for coexistence with many
    other devices, then asynchronous (device
    initiated transmissions) should be allowed.
  • A message may incorporate an indication whether
    it is a response to some inquiry/polling or not,
    but the central reader should also be able to
    accept those unexpected periodic transmissions.

Eliezer- InfoRange
Market Potential
  • Currently, security/access control and
    transportation are the most widely adopted
    applications in the RFID industry, but by 2006,
    supply chain management applications could hold
    the lions share of RFID market revenues.
  • The market for transponders in 2000 was about
  • The market for readers in 2000 was about 200M
  • With the availability of a global standard also
    having a location capability, the market
    potential for such applications is extremely high
