Abstract

This paper addresses the challenges to provide inexpensive, rapidly deployable broadband access through Free Space Optics (FSO) technology. It discusses the factors that are to be considered to design an adaptive optical wireless link. Link restoration techniques such as Dynamic Load Switching (DLS) and Multihop Routing are dealt elaborately. Implementation and computed results for DLS algorithm using median and mean estimation methods taking average power and BER as performance metric are given. Methodologies for atmospheric dependent multihop routing and zoned approach are discussed.
