Abstract
Namen diplomskega dela je opisati in raziskati stanje tehnologij LTE-Advanced in mobilni WiMAX serije standardov IEEE 802.16m (WiMAX 2), ki sta kot edini zadostili pogojem mednarodnega združenja za standardizacijo IMT-Advanced in s tem postali mobilni omrežji 4. generacije. Bralca najprej seznanimo z zgodovino razvoja mobilnih komunikacij skozi vse pretekle generacije do danes. Tako za LTE-Advanced kot tudi za mobilni WiMAX smo pobližje pogledali omrežno arhitekturo, frekvenčna področja delovanja in tehnologije prenosa informacij. Nekatere izmed njih so v uporabo stopile z mobilnima tehnologijama 4. generacije in s tem pripomogle k večjim hitrostim prenosa podatkov ter boljši optimizaciji omrežja. Kljub temu, da je bilo omrežje LTE na trg lansirano sedem let po omrežju WiMAX, je LTE v obdobju nekaj let pridobil veliko podporo s strani velikih telekomunikacijskih podjetij. Rezultat tega lahko vidimo v zadnjem delu diplomskega dela in se kaže v umestitvi omrežnih elementov LTE-Advanced v omrežje mobilni WiMAX. S to potezo operaterji WiMAX naredijo dokončen prehod na omrežje TD-LTE in si s tem zagotovijo širši krog uporabnikov ter boljšo podprtost najnovejših mobilnih terminalov.

Title:4th Generation Mobile Networks
Abstract:
The purpose of the thesis was to describe and explore the state of LTE-Advanced technology and Mobile WiMAX IEEE 802.16m (WiMAX 2) series of standards, which fulfilled the conditions of the international Association for Standardisation IMT-Advanced, and therefore became the fourth generation of mobile networks. Firstly, we introduce the history of the development of mobile communications, through all past generations until today. So for both, LTE-Advanced and mobile WiMAX, we take a closer look at network architecture, frequency area of working and the technology of information transmission. Some of them have entered into service with the 4th generation of mobile technology and by that contributed to higher data transfer rates and better optimization of the network. Despite the fact that the LTE network was launched on the market about seven years after the WiMAX network, it has gained a lot of support from large telecommunication companies in a few years. The result of this can be seen in the last part of the thesis, and it is reflected in the placement of network elements of LTE-Advanced to the WiMAX network. With this move, WiMAX operators are committed to complete the transition to TD-LTE network and thereby provide a wider range of users and the support of the latest mobile terminals.

Keywords:LTE-Advanced, WiMAX IEEE 802.16m (WiMAX 2), WiMAX to TDLTE harmonisation, 4th generation of mobile networks.
