Abstract
Wireless communication using free space optics (FSO) is becoming attractive for data transmission purposes. However, the system performance gets affected by atmospheric factors such as turbulence which induces beam wander effect thus degrading the reliability of FSO links. A turbulence simulation experiment is performed in laboratory to study the beam wander effect. A statistical prediction model for beam wander effect in a turbulent FSO link is presented. Based on this model, outage calculations are performed and compared against experimental values. The decline in outage due to increase in aperture area is computed both for predicted as well as experimental values. The results show similarity in both the values for small aperture sizes but differ for larger ones.
