  1. RFID Network Infrastructure: Backgrounder IEEE LANMAN 2007

  2. Background • UHF ‘Passive’ Radio Frequency ID • Developed through Auto-ID Center (MIT) sponsored research (1999-2004) • Specifications developed and ratified by EPCglobal and ISO • Readers talk first, tags communicate via modulated backscatter • Electronic Product Code (EPC) concept • General utility model, but… • Relies on back-end network resolution • Broad adoption across vertical markets • Started with Big Retail, DoD, and Pharma • Now add Air Transportation, Manufacturing, Logistics, Food Processing, Merchandising… • Expanding across applications • Open-loop, “supply chain” style • Closed-loop, “asset tracking” style • Technology is extending UHF applicability • Semi-passive tag technologies • User data memory • Sensor integration © 2007, Reva Systems Corporation

  10. RFID Infrastructure:Questions and Open Issues… • How will RFID impact enterprise networks? Does RFID create any special requirements for network bandwidth, latency, security, etc.? • Should RFID infrastructure be built with Edge v. Centralized Intelligence? Fat v. Thin readers? • How to define device-level v. system-level performance metrics? • What’s the best way to produce RFID identification and location context? What role does configuration or sensing play? • Comparison to and cooperation with other locating technologies, like WiFi RTLS, semi-passive UHF, HF, UWB? • How useful is RFID for emerging NFC applications? • What about RFID-enabled mesh networks? • How general-purpose can a locating infrastructure be made across multiple locating or sensing technologies? © 2007, Reva Systems Corporation
