RFID Middleware System based on the Low-Level Reader Protocol
Yang Yong Guo · ZTE communications · 2010
The application of Radio Frequency Identification (RFID) technology has proceeded rapidly in recent years. The RFID middleware system—between the application system and readers—is an important component of the RFID network,and functionsas a tag information processing centre. Conventional RFID middleware systems provide a unified ALE (Application Level Events ) interface for the upper layer application system ,while establishing a connection with readers by adapting to variable private interfaces. This is obviously not beneficial for the rapid construction of the RFID application system. On the other hand,another kind of RFID middleware system ,based on Low-Level Reader Protocol (LLRP),offers a standard interface for connecting readers of different manufacturers ,This significantly improves the efficiency of building the RFID application system.
