Paper Abstract
This paper firstly derives a new model of RoFSO (Radio on Free Space Optics) channel considering fluctuation speed of
the scintillation and the probability density function (p.d.f) of the random and time-correlated optical intensity disturbed
by scintillation. The relationships among frequency characteristic of RoFSO channel, variance of received optical
intensity and atmospheric conditions (temperature and insolation) are statistically analyzed by the proposed model. By
using the proposed model and the relationships, the throughput performance of WLAN (802.11a) over RoFSO link is
evaluated with computer simulations. For two cases of without-shadowing and with-shadowing in the radio propagation
channel, evaluations of degradation due to scintillation are conducted. As a result, it is found that the degradation due to
scintillation is much smaller than that due to shadowing in the throughput performance for WLAN.
