This Report provides a response to Question ITU-R 245/5 concerning free-space optical links for fixed service (FS) applications. The following sections present equipment characteristics, possible FS applications as well as technical and operational aspects of the free-space optical transmission (see Notes 1 and 2). NOTE 1 – The free-space optical transmission discussed in this Report focuses on systems for outdoor use. NOTE 2 – Free-space optical connection between a hub station and mobile/nomadic terminals serving as wireless local area network is outside the scope of this Report;however, a fixed link between hub stations is covered by this Report.
