Phase 4 of 4

Full Room-Scale Contactless Presence

The target state: front- and back-door UHF detection that distinguishes entry side, full RFID and camera correlation, and the complete presence-state machine running live in the trial classroom.

Draft, Most Advanced

What's Being Built

  • Doors: front and back UHF readers, positioned to distinguish entry side
  • Coverage: higher-gain or multiple antennas, sized for the full 60×40 ft trial room
  • Packaging: a real enclosure plan for whole-room hardware
  • Correlation engine: live, running the full presence-state model
  • Enforcement: per-period expected enrollment and bell-schedule-bound attendance windows in production
All acceptance and test cases from the Technical Detail page get validated live in this phase.

Acceptance Criteria

  • Front and back door UHF readers, positioned to distinguish entry side, sized for the full 60 by 40 foot trial room
  • Higher-gain or multiple antennas and a real packaging and enclosure plan for whole-room coverage
  • A live correlation engine running the full presence-state model: present, tardy, stepped out, left early, opted out, tamper, and so on
  • Per-period expected enrollment and bell-schedule-bound attendance windows enforced in production
  • All acceptance and test cases from the Technical Detail page validated in the live room
