Optical wireless as part of optical communications

The final report from the 23rd Telecommunications Educational Seminar focused on Optical wireless as part of optical communications and related topics held in Ostrava from the 3rd to the 5th of August 2015.

The 23rd Telecommunications Educational Seminar supported by the project "Development of Excellence of the Telecommunication Research Team in Relation to International Cooperation - CZ.1.07/2.3.00/20.0217" was held for three days in Ostrava at the room number EC3 from the 3rd to the 5th of August 2015.

This three days long seminar was organized with the help of prof. Dr. Erich Leitgeb from Graz University of Technology (Austria), who prepared for attendees lectures about "Free Space Optics (FSO), Optical Wireless Communications (OWC) - Introduction, Basics, Applications Part OWC1" a "Free Space Optics (FSO), Optical Wireless Communications (OWC), Atmospheric influence on OWC Part OWC2" and "Free Space Optics (FSO), Optical Wireless Communications (OWC), Results and Fog Measurements Part OWC3".

First lectures section was dealing primary with the basics of FSO networks, development in this field and advantages / disadvantages of this technology for communication networks. During his talk were presented research and development trends in the recent years.

Second lectures part was oriented at atmospheric influences on FSO links and selection of optimal light source. During this talk were discussed basic mathematical relations that are connected with parameters of optical power attenuation in FSO link and also optimal wavelength used by transmitter. Participants also have had a chance to get knowledge about turbulence influences and their mathematical descriptions.

Last presentations from prof. Leitgeb were aimed at his scientific work and results in the FSO field. He also introduced future possibilities of FSO links in case of telecommunication operators. Very perspective utilization of FSO in satellite communication that is being nowadays used more and more was also mentioned.

The other large part of this seminar was devoted to the personal consultations with prof. Leitgeb in the FSO field and establishing of future possibilities of cooperation between universities as well as internships for academic employees and students.

Thanks to presented specialized lectures and consultations our students and employees had opportunity to take a closer look into the problems with Optical wireless communications.
