||The focus of this bachelor’s thesis are various methods in which the frequency spectrum is allocated and a valuation of the frequency spectrum. At the beginning there is a description of mobile communication technologies and the individual bands of spectrum used by mobile operators for a better understanding of the topic. There are also described various methods in which the frequency spectrum is allocated. Special attention is paid to auctions because they are currently the most used method of spectrum allocation. Auctions that have already been completed and selected auctions that are in preparation are described in the next chapter. Finally, the value of the frequency spectrum in various bands is analyzed using data from European auctions that have been described in the chapter before. More attention is paid to the value of the digital dividend where various factors influencing the value are examined.
