12  Abstract — We have proposed and demonstrated a novel architecture of a radio over fiber (RoF) system in this paper. In this downlink system, the base band data signals are carried by the optical millimeter-wave generated at the central station and converted to the electrical RF signal by a converter at the base station before we distribute them through antenna. Here we generate and transmi...

Abstract— A Radio over Fiber (RoF) distribution network based on single-mode fiber (SMF) and a combination of coherence multiplexing (CM) and subcarrier multiplexing (SCM) is proposed. CM is a relatively unknown and potentially inexpensive form of photonic code-division multiplexing, and is used here as a means to distinguish between the radio access points (RAPs). Two alternative CM network to...

In this paper, we propose a medium access control (MAC) protocol to allow a radio over fiber-based wireless local area network (RoF-based WLAN) to coexist with legacy carrier sense multiple access with collision avoidance (CSMA/CA)-based WLANs. In RoF-based WLANs, there are long propagation delays between access points (APs) and stations (STAs). When an RoF-based WLAN uses the conventional CSMA...

Recent advancements in microwave and terahertz photonics technologies has led to development of innovative advanced wireless communications systems. One of the emerging promising technologies is Radio-on-Free-Space Optical (RoFSO) system described in this paper. RoFSO is achieved by combining Radio-over-Fiber (RoF) technique and free-space optical (FSO) communication technology using seamless c...
