Abstract
Disclosed is an RoF system providing an HD wireless communication service. The RoF system includes the base station for transmitting and receiving each of the TDD/FDD individual signals and TDD/FDD combined signals, channel-combining downstream signals for a TDD scheme with downstream signals for an FDD scheme, and generating TDD/FDD mode control signals; a base station donor for receiving downstream RF signals from the base station, converting the resultant signals into downstream optical signals, outputting the converted signals, and delivering upstream optical signals, which are input to the remote station from the wireless terminals, to the base station; and the remote station for switching a corresponding duplexing mode operation according to wireless service channel states of the wireless terminals, converting the downstream optical signals transmitted from the base station donor into service RF signals, amplifying the converted service RF signals, and providing the amplified service RF signals to the wireless terminals through antennas.
