Free-Space Optics data link
Šála, Jakub ; Číž, Radim (referee) ; Šporik, Jan (advisor)
In this thesis, shows a current issue for free space optics, limiting their use in practice with regard to the availability and reliability. They conducted measurements on wireless optical links and the observed values is calculated by the availability of the connection. Subsequently, measurements are performed on alternate versions of wireless and copper connections. Observed values were compared with a wireless optical link. It is made of optical design of wireless connections at home.

Design of the Computer Network at the Elementary School
Novák, David ; Jordán, Vilém (referee) ; Ondrák, Viktor (advisor)
This thesis focuses on the issue of designing of the computer networks, it proposes specific solution for the building of elementary school. This work describes procedure for designing computer network and preparation which the school must do before starting the installation of the network. In work is described, which components are necessary to create the computer network and what properties must have. In this thesis are taken into account best possible use and acceptable price for school.

Coaxial cables in communication networks
Hotárek, Lukáš ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The semestral thesis is focused on coaxial cables, its development and current utilization. In the prologue of this paper, the history and origin of the cable is described with mentioning important dates and events in its development. Since the coaxial cable is type of metallic cable, part of the paper deals with the theory, parameters and characteristics of metallic cables. The theory of all basic types of metallic cables is described, that implies twisted pair, structured cabling and coaxial cable, to which is dedicated most space. The next chapter presents brief description, basic division and utilization of fiber optic to enable comparison with coaxial cable. It presents main advantages and disadvantages as well as reasoning for prevalence of use of optic fibers. The current use of coaxial cable is presented. Aside from cable television, computer and telephone networks, the coaxial cables are also used as feeder lines for transmitting and receiving aerials and as television aerial lead. Due to great possibility of utilization of coaxial cables exists a broad spectrum of cables with different parameters and properties. Therefore a separate chapter focuses on particular types of cabling, describes its significant parameters and practical utilization. The last part of the paper presents parameters of coaxial cables that can be verified and that bear great importance in praxis. The methods of proper measurement are mentioned. Aforesaid parameters include impedance, cable loss and distance-to-fault. Described are also modern analyzers that are most commonly used for measuring said parameters of coaxial cables and aerials.

Company Computer Network Design
Herodková, Veronika ; Jordán, Vilém (referee) ; Ondrák, Viktor (advisor)
The bachelor‘s thesis deals with the design of a computer network in chosen company. In the analytic section of thesis, I describe the computer network and demands of the investor on new computer network. In the last section of bachelor‘s thesis is the design of structured cabling system itself, which comes from previous analysis of computer network and demands of the investor.
