RF-iT Solutions uses a concept called a “Tube”. What is a Tube? A Tube is a complete solution for an identification point. They represent a communication channel between tags or devices and IT back-end systems. At a macro level, Tubes include the specification and configuration of the hardware and the environment of the RFID subsystem at an RFID Identification Point—starting with the specification of transponders to the definition of a parameter set for reader and antennas, filter- aggregation and data processing routines up to the interfaces to Enterprise IT systems. Optionally Tubes can have a graphical user interface or, for example, a connector to automation equipment (Programmable Logic Controllers).
