Reader Protocol: EPCglobal Ratifies Low-Level RFID Reader Protocol

GS1 EPCglobal Inc. recently announced the ratification of the Low-Level Reader Protocol (LLRP) standard. Use of LLRP allows readers to be operated to deliver optimal performance resulting in rich, accurate, actionable data and events. The LLRP standard will further foster reader interoperability and create the foundation for technology providers to extend basic capabilities in satisfaction of industry-specific requirements.

This new standard, produced by the EPCglobal Reader Operations Working Group, defines a high-performance, flexible and extensible interface for operating network-connected RFID readers. The protocol is the result of collaboration between over 90 companies including end users, RFID infrastructure vendors, middleware vendors, industry experts, and networking professionals.

"The LLRP effort brought together industry leaders with a broad perspective and advanced the state of the RFID industry," said David Husak, Co-chairman of the EPCglobal Reader Operations Working Group, and Chief Technical Officer of Reva Systems Corporation. "In particular, the participation of prominent RFID end users helped to ensure that LLRP will meet the broadest possible range of industry requirements, worldwide."

LLRP supplies the functionality around reader operations in compliance with the EPCglobal Architecture Framework. It is the first interface specification that provides comprehensive support for all control and data features of the EPCglobal Class1 Generation 2 UHF Air Interface Protocol.

"Gen2 was the first big step toward broader adoption of passive RFID and EPC technology, it changed the marketplace by standardizing the tag-to-reader air interface," said Chris Adcock, president of EPCglobal Inc. "By standardizing the next critical architecture layer, the LLRP reader-to-network interface is expected to move the industry another step along the path to widescale enterprise adoption."
