Abstract
We propose a scheme of a radio-over-fiber (RoF) network supporting the simultaneous transmission of radio frequency identification (RFID), Wi-Fi, and ZigBee services. All services share the same optical transmitter and receiver to reduce the network complexity. Error vector magnitude (EVM) values of 0.36%, 1.23%, and 0.25% can be achieved in the downlink for RFID, WiFi, and ZigBee signals, respectively. The corresponding EVM values in the uplink are 0.37%, 1.78%, and 0.29%, respectively. The scheme is verified over a 2 km RoF link where RFID, WiFi, and ZigBee master nodes can communicate normally with their slave nodes.
