ABSTRACT
The article analyzes the advantages and disadvantages of free space optics (FSO). It uses infrared light-emitting-diodes to allow optical wireless exchange of data, voice and video. Up to 10Gbps are used through the air from 20 meters to 5 kilometers without the need to lay cables and radio frequency spectrum licenses. FSO is cheaper and easier to install and maintain than fiber optics. It is also difficult to intercept and to jam. However, FSO is subject to environmental variations such as fog, absorption, scintillation, scattering and building sway or earthquakes.
