LLRP
The EPCglobal Low Level Reader Protocol (LLRP) is a standardized communication interface for RFID readers, enabling efficient management and data transfer between RFID devices and backend systems. It simplifies interoperability across RFID hardware from different vendors, supporting real-time monitoring and control of RFID operations..
EPCglobal Low Level Reader Protocol (LLRP) is a standardized protocol developed to facilitate communication between RFID readers and enterprise-level applications. It provides an abstracted, unified interface for managing RFID devices, regardless of manufacturer, simplifying integration within RFID infrastructures. LLRP operates primarily over TCP/IP networks, supporting commands for setup, inventory control, tag reading, and event notifications.
LLRP's design emphasizes a low-level command structure implemented via XML messages exchanged over network sockets. This allows developers to finely control parameters such as radio transmission power, filtering criteria, and tag singulation algorithms. The protocol supports real-time inventory operations and event-driven reporting, enabling fast, reliable RFID data acquisition with minimal latency.
Integration of LLRP into enterprise systems can be achieved through middleware platforms or direct socket programming, enabling seamless connection of RFID edge devices with inventory management, supply chain, and ERP systems. Due to its widespread industry adoption, LLRP helps standardize RFID deployments and reduces vendor lock-in concerns.
