Energetska učinkovitost mobilnih omrežij 5G

BANOŽIĆ, DANIEL (author), Humar, Iztok (mentor)

Trenutno stanje tehnologije 5G mobilnih omrežij je v zgodnjih fazah razvoja. Veliko podjetij in univerz je ustanovilo raziskovalne skupine, ki razvijajo tehnologije, katere bo moč uporabiti pri izgradnji pete generacije mobilnih omrežij. Prav tako se pomembnosti razvoja pete generacije mobilnih omrežij zavedajo skupine zadolžene za standardizacijo (angl. Third Generation Partnership Project - 3GPP). Nove tehnologije, ki se bodo uporabljale v peti generaciji mobilnih omrežij, se bodo začele postopoma pojavljati in uporabljati v četrti generaciji mobilnih omrežij. Poleg visokih prenosnih hitrosti, zmanjšanja zakasnitev na manj kot 1 ms uporabe centimetrskega in milimetrskega frekvenčnega spektra nam omrežje pete generacije prinaša ogromno novosti na področju brezžičnih komunikacij, industrije ter osebnih navad uporabnikov. Z uvedbo 5G omrežij se predvideva, da bo promet v brezžičnih omrežjih narasel za 10.000 krat, prav tako se predvideva, da bo naraslo število naprav, ki se bodo posluževale novega omrežja. Največja novost bo uporaba heterogenih baznih postaj ter delitev na komunikacije na prostem in znotraj zgradb. Diplomska naloga opisuje peto generacijo mobilnih omrežij. Uvodni del kratko predstavi razvoj 5G omrežja, razdelitev razvoja omrežja na štiri faze in umestitev celotnega projekta 5G omrežja med leti 2012 in 2020. V nadaljevanju so predstavljene potencialne tehnologije za omogočanje doseganja zahtev omrežja 5G ter možne rešitve na področju arhitekture 5G omrežja. Osredotočil sem se tudi pomembna problematika energetske učinkovitosti 5G omrežja. Predstavljena so tudi heterogena mobilna omrežja in problem optimalne porazdelitve baznih postaj v njih. Za realizacijo praktičnega dela diplomske naloge sem napisal skripto v programskem orodju Matlab. Skripta mi je bila v pomoč pri matematičnih izračunih in pridobivanju rezultatov ter ugotavljanju optimalne porazdelitve baznih postaj v heterogenih mobilnih omrežjih.

Abstract

Technologies for 5G mobile networks are in early stages of development. Many businesses and universities have established research groups which are developing technologies that will be used in the construction of fifth generation mobile networks. There are also groups (3GPP) that are responsible for the standardization of fifth generation of mobile networks. New technologies that will be used in the fifth generation of mobile networks will begin to emerge gradually and will be also used in fourth generation mobile networks. In addition to the high transmission speed, reduced latency to less than 1 ms and the use of centimeter and millimeter frequency spectrum of a network. The fifth generation brings a lot of innovations in the field of wireless communications, industry and personal habits of users. With the introduction of 5G networks, it is assumed that traffic in wireless networks will grow 10,000 times. The increase in number of devices that will use the new network is also expected. The biggest innovation is use of heterogeneous base stations and divisions of communication on those that take place inside buildings and those that take place outside. Thesis describes the fifth generation mobile networks. Introductory part describes the development of the 5G network and the distribution of development in four phases and places the entire project of development 5G networks between years 2012 and 2020. In the following chapters are presented potential of the technology to permit the achievement of a 5G network requirements and possible solutions in the field of architecture of 5G networks. Also is presented an important issue of energy efficiency in 5G networks. There are also presented heterogeneous mobile networks and problem of the optimal distribution of base stations in heterogeneous mobile networks. For realization of the practical part of the thesis I wrote a script in Matlab programming tool. The script helped me with mathematical calculations, obtaining results and determining the optimal distribution of base stations in heterogeneous mobile networks.
