Comparison of Wireless Optical Communication Availability Data and Traffic Data

Optical Wireless link provides high bandwidth solution to the last mile access bottleneck. However, an appreciable availability of the link is always a concern. Free Space Optics (FSO) links are highly weather dependent and fog is the major attenuating factor reducing the link availability. However the traffic requirement of a LAN may not require 99.999% availability of FSO at all instants. A hybrid network with intelligent switch over can fulfil the availability and bandwidth requirement. In this paper statistical data of fog and FSO availability in Graz (Austria) has been compared to the traffic data of Technical University Graz (Austria).
