Project Scope and Purposefor 1451.7 (this is
what had to be submitted to IEEE for approval in
creating a new Standard)

• Project scope This standard defines
  communication methods and data formats for
  transducers (sensors and actuators) communicating
  with RFID tags that follow the ISO/IEC 24753
  standard. The standard also defines Transducer
  Electronic Data Sheet (TEDS) formats based on the
  IEEE 1451 family of standards and protocols for
  accessing TEDS and transducer data. It adopts
  necessary interfaces and protocols to facilitate
  the use of technically differentiated, existing
  technology solutions. It doesnt specify
  transducer design or signal conditioning.
• Project purpose There is currently no openly
  defined independent interface standard between
  transducers and RFID tags. Each vendor builds
  its own interface. Without such standard,
  transducer interfacing and integration to RFID
  tags and systems are time-consuming and all
  vendors duplicated efforts are economically
  unproductive. The purpose of this standard is to
  provide interfaces and methods for interfacing
  transducers to RFID tags and reporting transducer
  data within the RFID infrastructure. It also
  provides means for device and equipment
  interoperability.

PAR Submittal Approved

• March 23 - Approval of IEEE Work Item
• March 30 - First official meeting of IEEE 1451.7
  Working Group
• Produced working outline of desired items to go
  into 1451.7
• Currently working on TEDS information to coincide
  with 24753

Monthly meetings - Topic - 1451.7

• Held first face-to-face meeting in June, 2007
• Discussed layout of logical diagram
• Physical diagrams currently being created
• We are making progress, but we still have to work
  towards a clear systems architecture for linking
  1451 compliant sensors to an RFID tag.
• The1451 standards currently do not cover all of
  the issues such as
• identifying gases, (IEEE folks will create table
  for gases)
• only working in SI units, and
• Small TEDS being defined.

1451.7 Logical Diagram
8

• Working towards a document that leans towards
  simple sensors, and intelligent/smart readers.
• Definable configuration of data stored on TAG
• Multiple sensors on single unit supported
• Data to be stored on the TAG
• Will we add another type of sensor for batteries?
• Interface with 18000 series written in 18000
  series
• 24753 has been granted a 1 year extension, to aid
  in the alignment of 1451.7

IEEE Sensor Coordination (IEEE 1451.7)

• Interfaces under consideration
• SPI (Serial Peripheral Interface)
• I2C (I Squared C)
• Potential synergy with ubiquitous sensor networks
  (USN)

10
Cooperation Needed!

• There are now multiple documents across three
  working groups (more evolving) that have to be
  coordinated in order for this new standard to be
  all inclusive - that is, to not leave anything
  out, conflict, or overlap.
• 15961-4 SC 31/WG 4/SG 1 (commands)
• 24753 SC 31/WG 4/SG 1 (ISO sensor
  document)
• 1451.7 SC 31/WG 4/SG 1 / IEEE (RFID for
  Sensors)
• 18000-6C SC 31/WG 4/SG 3 (air-interface)
• 18000-x SC 31/WG 4/SG 3 (air-interface)

IEEE 802.15.4

• The IEEE 802.15 TG4 was chartered to investigate
  a low data rate solution with multi-month to
  multi-year battery life and very low complexity.
  It is operating in an unlicensed, international
  frequency band. Potential applications are
  sensors, interactive toys, smart badges, remote
  controls, and home automation

12
IEEE 802.15 TG4 CURRENT STATUS

• The IEEE 802.15.4-2003 standard has been
  superceded by the publication of IEEE
  802.15.4-2006. The new standard can be purchased
  from the IEEE store. The TG4 task group put
  itself into hibernation at the March 2004 meeting
  after forming a task group (TG4b). The new task
  group 4b completed is work with the publication
  of the revision.
