RFID en växande företeelse inom alla brancher

Improving Efficiency with Real-Time Status

Vi kommer företrädelsevis att titta på

sk In Building Asset Tracking

(dvs med ett underliggande WLAN)

Varf r rtls

Varför RTLS?

  • Leverage WLAN infrastructure with Wi-Fi-based asset/personnel tracking and location applications

  • Fast locating of tagged equipment improves core services

  • Location context for workflows makes business operations and processes more efficient

  • Locating lost or missing equipment saves money

  • Preventing theft reduces cost

    Olika typer av lokaliserings tj nster rtls vs conventional rfid

    Olika typer av lokaliserings tjänsterRTLS vs. Conventional RFID

    • Passive RFID - Short Read Range Identification Technology

      • Chokepoint-based

      • More data than barcode, easily readable, becoming inexpensive

      • Standardized (EPC Global )

      • Primarily an identification resource – not for location tracking.

  • Active RFID - Location Tracking – Point Solutions

    • Use portals/scanners as overlays to existing LAN/WLAN

    • No standards proprietary networks

    • Various frequencies, tags & vendors create incompatible silos

    • Varying levels of performance, scalability and accuracy

  • RTLS - Location Tracking – Leverage 802.11 coverage

    • Real-time enterprise-wide location tracking

    • Proprietary overlay systems over 802.11 networks

    • Open standards 802.11-based leverages WLAN infrastructure

  • Seminarium 8 location system rfid taggar

    Access Point

    3. Patient Monitor sends alarm message to Alarm Manager

    5. Attending Nurse’s WLAN handset rings and a text message is displayed indicating problem and monitor the alarm was sent from. Nurse is busy and does not accept the alarm

    2. An alarm is triggered

    1. Patient Monitor detects an out of bounds condition
