N2 - Radio-on-free space optical (RoFSO) communication systems are gaining popularity because of their ability to transmit simultaneously multiple radio frequency signals comprised of various wireless services over FSO links using wavelength division multiplexing technology. We propose a new approach of use of the RoFSO technology for high-speed indoor communication systems and introduce an analytical model for the transmission of orthogonal frequency-division multiplexing-based signals over a line-of-sight link with diverged Gaussian beam. We have analyzed the laser safety restrictions for the proposed system and derived a closed-form bit-error probability, taking into account the ambient noise and laser diode nonlinear distortion. Simulation results are shown and the system performance is discussed.
