The transmission speed enhancement techniques in TKR
Šťovíček, Petr ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
The purpose of this work is to assess and propose possible methods for increasing the transmission speed of the cable television distribution, concretely the UPC network in Brno. The first part of work collectively processes general knowledge and gives the reader into the issue. After that follows an analysis of TV cable networks UPC in Brno, especially view of data transmission. After familiarization with the physical aspect of the network is described data communications itself, including standard DOCSIS, respectively EuroDOCSIS. Particular attention is paid to factors that have effect on data transmission and speed. Benefit is the calculation of dividing ratio in different parts of the network and compared with the real load. As far as possible in the given work results of measurements with regard to the quality of the network. The last part is about how to increase speeds. Perspective solution is mainly a technology which is based on standard EuroDOCSIS 3.0, which introduces the concatenation of individual channels. Result of made tests of first cable modem EuroDOCSIS 3.0 confirms the very high speeds and currently preparedness for other major step in so long development of TV cable network.

DOCSIS Technology in Access Networks
Pirohanič, Lukáš ; Šilhavý, Pavel (referee) ; Horváth, Tomáš (advisor)
This bachelor thesis explains the design and implementation of data communication between a central unit and a cable modem. Suitable transfer medium and intermediate devices for signal forking and amplification are chosen in practical part of the work. The upstream and downstream channel transfer rates are tested using modulation techniques and also testing the DOCSIS Network for qualitative parameters and laboratory task dealing with the DOCSIS standard. The theoretical part describes DOCSIS standard, CATV network architecture and signal modulation during transmission.
