RFID Data-Capture Standards: LLRP and ALE

Published: February 22, 2013

The first task in many RFID implementations is to interface with RFID interrogators—a task that is significantly more complex than interfacing with a bar-code scanner. Fortunately, there are widely adopted standards that help ease the task, and that enable developers to focus on the business problem they are trying to solve. The Low Level Reader Protocol (LLRP) provides a standardized interface to RFID interrogator devices, and the Application Level Events (ALE) standard defines a standardized way for application business logic to obtain the data it requires from a network of RFID devices. This session will explore these two standards in detail, outline their use in commercial products, and show how developers can utilize them to rapidly build robust, vendor-independent RFID systems.
