A dynamic, reconfigurable, intelligent radio-over-fiber （I-RoF） system can integrate fiber and wireless access systems. It can provide efficiency, flexiblility, and broadband capability by using new network architecture, MAC layer protocols, system link, and key components. In this paper, we describe the network architecture for I-RoF technology in the network layer. We describe the specific design that can improve the performance of I-RoF and ensure the dynamic control of joint resources in the MAC layer. We also describe the technologies that deal with RF processing, transmission, and control in the optical domain in the system layer. Finally, introduces new technologies and special structures that can improve the performance of the filter and antenna.
