Overview
This high performance UHF antenna multiplexer system is intended for networking and distributing UHF RFID antennae to enable real-time item level assets tracking and management. It is also an ideal choice for smart shelf, electronic label shelf and other RFID applications. This antenna multiplexer utilizes master and slave unit design and all information exchange between master and slave goes through RF cables so no extra communication cabling is needed.
It utilizes a proprietary intelligent identification algorithm and can realize as many as 32 slave multiplexers and 256 antenna connections. It also provides real time antenna connection status.
