Real Time Locating Systems (RTLS)

• Terms of Reference
• by Marsha A. Harmon

ANSI ASC INCITS T20

• Real Time Locating Systems (RTLS)
• After 21 months of development has published an
  approved standard including
• ANS INCITS 371.1 - 2.45 GHz Protocol Air
  Interface
• ANS INCITS 371.2 - 433 MHz Protocol Air
  Interface
• ANS INCITS 371.3 - Application Program Interface
• Following INCITS 371 publication, decision made
  to take the standard to international, choices
• Fast track through JTC 1
• NP/CD, plus new efforts in ISO TC 122/104 JWG
• NP/CD, plus new efforts in JTC 1/SC 31 as a
  separate technology gt gt gt SC 31/WG 5

RTLS Technology or Application of RFID?

• ASC INCITS T20 strongly feels that RTLS is a
  separate and distinct technology from that of
  RFID in much the same way as wireless local area
  networks are a separate and distinct technology
  from that of RFID.
• All three services may share the same
  electromagnetic space but they are uniquely
  separate technologies.
• The SC 31 leadership and 122/104 JWG agree

TC 122/104 JWG Resolution

• JWG and INCITS T20 believe that SC 31 is the best
  place for this technology standard. JWG deals
  onlywith applications
• Resolution 2 (JWG n03061 - Auckland 2003-03-25)
  
• New Work Item for Real Time Locating Systems
• ISO/TC 122/104 JWG recognizes the value of the
  Real Time Locating Systems technology in
  potential applications of Automatic
  Identification and Data Capture. The JWG looks
  to ISO/IEC JTC 1/ SC 31 to provide technical
  standards in support of applications in the
  supply chain. We recommend that a proposed New
  Work Item (NP) for RTLS, to be initiated by the
  INCITS T20 committee, should be brought forward
  to SC 31.
• UNANIMOUS

Fast Track

• Document must go through without any changes.
  INCITS attempted to convince T20 to move the
  document internationally through Fast Track
• INCITS T20 believes that there are other
  technologies meeting different application needs
  that would be excellent candidates for
  international standardization
• While INCITS T20 has met monthly for nearly two
  years to develop this American National Standard,
  it encourages international review to create the
  best set of RTLS standards possible
• INCITS T20 feels the best way to encourage
  international adoption of its work and the
  incorporation of new technology is through an
  NP/CD process, not a Fast Track process

Real Time Locating Systems (RTLS)

• An ADC technology that provides both
  identification and location, generally through
  multi-lateration
• Types
• Sign Post/Localizers (Been Here)
• Time of Flight Ranging Systems
• Amplitude Triangulation
• Differential Time of Arrival (DTOA)
• Cellular Triangulation
• Satellite Multi-lateration

7
Types of RTLS

• Conceptually there are five types of RTLS
• Locating an asset via satellite - requires
  line-of-sight - resolution to 10 meters
• Locating an asset by virtue of the fact that the
  asset has passed point A at a certain time and
  has not passed point B
• Locating an asset by virtue of providing a homing
  beacon whereby a person with a handheld can find
  an asset
• Locating an asset in a controlled area, e.g.,
  warehouse, campus, airport - area of interest is
  instrumented - resolution to 3 meters
• Locating an asset in a more confined area - area
  of interest is instrumented - resolution to 10s
  of centimeters
