We experimentally demonstrated a remote antenna system based on a millimeter-wave (MMW) over fiber scheme for 622-Mbps broadband fixed wireless access systems. In this system, the format of the RF signal is based on a four-carrier signal in which each carrier is modulated by using 64-QAM, to reduce the complexity of the RF system in comparison with the single-carrier QAM system using many more signal-points than 64. The remote antenna system based on the IF-over-fiber scheme was also experimentally demonstrated, as well as the MMW over fiber scheme for comparison. From the experimental results, we found that the remote antenna system based on the MMW over fiber scheme is effective not only from the viewpoints of miniaturization of the remote antenna station and ability to provide a stable millimeter-wave frequency, but also from the viewpoint of link performances such as allowable dynamic range and power penalty, even though the scheme's E/O and O/E devices have a higher cost.
