Development project of radio on free space optics

Radio on Fiber (RoF) technologies are available to realize a universal platform for transparent forwarding various types of wireless services under multi air interferences coexistence in a ubiquitous network environment. By applying free space optical techniques for RoF, its concept can be extended to free space channels. This paper describes a development project of DWDM Radio on Free Space Optics (RoFSO) system, which can realize a universal platform to quickly and effectively provide ubiquitous wireless services for rural areas. Radio on Free Space networks using RoF, RoFSO, and Radio on Radio (RoR) realize software definable radio networks, which is configured with the combination of Virtual Radio Free Space Network using radio on free space networks, software definable radio gateway, wireless service over IP, and radio agents. This paper also describes the availability of software definable radio networks for ubiquitous wireless.
