Middleware
Middleware is the software that the data read out by an RFID reader send to a control system.
Mobile Reader
A mobile reader is not firmly integrated in a system and can be carried. It may be cabled or uncabled.
Opposite stationary reader.
Modulation
The best known forms of modulation are amplitude modulation (AM) and frequency modulation (FM), these also being used in RFID. A useful signal is modulated onto what is called a carrier signal or alters the carrier signal to transmit the useful signal. The useful signal is retrieved at the receiving end by a demodulator. In this way both analog and digitial signals can be transmitted.
Multiplexer
A selective switching network in which one input is selected from a defined number of inputs by an analog or digital circuit and connected to a defined output.
