Diversity in Control
• Set-and-forget reader operation
– E.g., conveyor belt, handheld readers
• Real-time control of reader operation
– E.g., dock door operation
• Real-time control only when triggered
– E.g., Wrapping station operation
• Other operations that may require preprovisioning the reader for local action or a
network interaction for database access)
– E.g., Kill a tag at Point-of-sale
– Tag commissioning

Slide 10
Diversity in Data Traffic
• One tag every read
– E.g., conveyor belt
• 10s of tags every read
– E.g. handheld
• 100s of tags every read
– E.g., dock door operation, wrapping station
• Tag data + Sensor data
– E.g., readers deployed in cold chain applications, airline
parts tracking

Low Level Reader Protocol
(LLRP)
• 80+ companies participated in this
standardization effort
– Reader vendors, end users, middleware
vendors, network and RFID infrastructure
vendors
– Direct and indirect end user inputs on the
requirements
• A ratified standard
