Whats IP-X protocol?

• A non modulated reader protocol also called Tag
  Talk Only (TTO) or Tag Talk First (TTF)
• Tag transmits their message randomly in time upon
  reception of enough field to power-up
• Very helpful for spectrum difficult situation
• Ability to detect extremely fast moving object
• Minimum complexity for tag IC
• Reader talks when it needs to program data into
  the tag

• Should be other applications than supply chain
• Deployed in largest item level tagging project in
  apparel and fashion application
• For highly dynamic tag populations in difficult
  RF environment
• Explosives
• Miner equipment and safety
• Vehicle identification
• Paper real
• Non-interference not proven
• Could be assured by introduction of TOTAL (Tag
  Only Talks After Listening) check CISC

• Multiple frequencies do not fit into the 18000
  structure
• Reduction on single frequency parts can be done
• Impact on communication quality of cellular
  phones
• Report from Vodacom South Africa shows no issues
• Technology already deployed in Japan
• Data structure compatibility must be ensured
• Various parts of 18000 show different data
  structures. Preferred data structure would be
  supported.

• Only supported by a single vendor and no market
  penetration
• Chips have been selling commercially since 1999
  by EM-Microelectronic. More than 100Mio IP-X UHF
  chips sold, qties will more than double in 2007.
• Technology deployed by MarksSpencer (UK) for men
  suite, women suite and women casual garments
  tagging. Largest Item Level Tagging project in
  apparelfashion application worldwide.

• Technology supported by multiple inlay/label
  suppliers such as IER, KSW, ASK, Paxar, Vanskee,
  Sokymat, Smart tag, Syrmatech, Power
  Paper/PowerID
• Technology supported by multiple reader suppliers
  such as IER, Feig electronic, Deister, AWID,
  Smart ID, iPICO, Kiscomm, Samsys (taken over
  SIRIT), CNE, SyGade.

How to ensure co-existence of RTF and TTF
technologies?

• Introduction of TOTAL(Tag Only Talks After
  Listening)
• Leverages the speed advantage
• Automatically detects any other communications
  and shuts down
• IP-X TOTAL tags will by principle step back in
  case of other running applications. It could be a
  way to address all future TTF type tags.
• Evaluation simulations shown today
