Skrócony opis: (tylko po angielsku)

The module presents the fundamentals of wireless optical communication systems (OWC). Analysis of the OWC device's construction and its limitations is performed. Factors influencing both range and data rate have been defined considering conditions of radiation propagation for different environments and various physical phenomena. Significant parameters of OWC construction elements (lasers, detectors, optical systems, modulation, and coding techniques) are determined considering the properties of communication systems. The current state of both underwater and terrestrial communication technologies is presented.
