Abstract :
The benefits of free space optics (FSO) motivates to use it for future high data rate demanding communication applications. However, widespread growth of the technology has been hampered by reduced availability due to weather influences on the link. The alternate is to use back up RF link for improving the availability. But it requires intelligent switching back and forth between two links. The forward prediction of the received signal strength can greatly improve the performance of such hybrid network. The forward prediction approach has been analyzed using measured FSO attenuation data. The results are analyzed in terms of mean square error.
