Link design of Radio on Free Space Optic system for heterogeneous wireless services

Radio on free space optics (RoFSO) is being developed to realize a cost effective and universal platform for heterogeneous wireless services as same as RoF. The developed RoFSO transceiver can directly transmit some RoF signals from an optical fiber and can receive an RoFSO signal from air into a fiber core. It can achieve an free space that is transparent for various types of wireless services in an optical wireless beam. This paper describes the features of developed equipments, and propose the link budget design for WLAN and terrestrial digital broadcasting services.
