PROJECT TOPICLogistics, Warehousing & Smart Retail
RFID Smart Portal Tunnel
A warehouse telemetry concept investigating electromagnetic RF shielding chambers, circular polarized antenna phasing, and anti-collision tag algorithms to count dozens of RFID-tagged items inside sealed totes.
Bulk Contactless Ingestion Verification
- ✓Reads hundreds of packed item tags simultaneously without opening shipping cartons.
- ✓Prevents RF spillover reading stray warehouse tags using carbon-embedded absorbing foam.
- ✓Synchronizes conveyor belt encoder ticks with RFID tag timestamp records.
The Engineering Challenge
Problem / Objective
Opening every incoming tote to manually scan barcodes creates massive receiving docks bottlenecks and slows throughput.
