Alien Technology, an industry leader in RFID UHF products and services, announced a software update for its Enterprise Class readers (ALR-9900+ and ALR-9900+EMA) that supports LLRP (Low-Level Reader Protocol) Version 1.1. LLRP is a specification from GS1 EPCglobal for a standard network interface between RFID readers and controlling software or hardware.
The goal of LLRP is to simplify application development for end-users, eliminating the need to conform to different proprietary communication protocols provided by each RFID vendor. Users of competitive readers can now easily migrate to Alien’s more advanced hardware solutions.
“While LLRP enables cross-reader migration, it is a low-level paradigm and quite different from Alien’s high-level and much more autonomous ARP,” said Steve Smith, Alien’s chief technology officer. “LLRP is a binary protocol and can be thought of as programming in assembly code, whereas ARP is analogous to programming in a high-level language.”
