20.500.12556/RUL-83508 Načrtovanje mobilnih sistemov v zgradbah Planning of mobile in-building systems Vsi uporabniki v mobilnih omrežjih se vsakodnevno srečujemo s problem dostopa do mobilnih storitev in največkrat se nam to dogaja ravno v zgradbah. V diplomskem delu sem se osredotočil na problematiko zagotavljanja visoke kvalitete mobilnih storitev v zgradbah. V uvodnem delu sem predstavil napovedi rasti podatkovnega prometa ter problematiko zagotavljanja dostopa do mobilnih storitev v zgradbah. Statistike namreč prikazujejo, da se večji del celotnega prometa generira ravno v zaprtih prostorih. Načrtovanje mobilnih sistemov za zgradbah postaja najpomembnejši del načrtovanja radijskega omrežja saj v prihodnje z makro omrežjem ne bo možno zagotavljati potrebnih prometnih kapacitet ter s tem visoke kvalitete mobilnih storitev. Za različne generacije mobilnih omrežij sem opisal tehnologijo in lastnosti radijskega vmesnika. Ločeno sem predstavil še postopek izročanja zvez, ker pomembno vpliva na uporabniško izkušnjo in omogoča nemoteno uporabo mobilnih storitev povsod, kjer je prisoten radijski signal mobilnih omrežij. S praktičnim primerom sem prikazal postopek načrtovanja mobilnega sistema v dvorani Stožice. Predstavil sem bistveno razliko med aktivnim in pasivnih distribuiranim antenskim sistemom. Podane so tudi zahteve investitorja in postopek verifikacije delovanja sistema. S fleksibilno zasnovo sistema so omogočene tudi bodoče nadgradnje , ki so navedene v zaključku naloge. All mobiles users are experiencing issues with access to mobile services on a daily basis and most these happen while we are indoors. In my finally thesis i have focused on importance of delivering high quality mobile services to end users in different indoor environments. In the introduction part i am presenting the global traffic forecast for the next 4 years which is rapidly increasing. The fact that most of the traffic is generated indoors is the trigger for analyzing the future radio network design where in-building systems and small cells will have a key role while trying to serve end users demands. In the main part I have covered different radio network technologies and their specifics on the radio interface. I have also described the handover procedures since they have a huge impact on end user experience. As practical example I have focused on in-building system design for basketball arena in Stožice. Designing of an in-building system for sport arenas and stadiums is one of the most difficult projects since it is basically impossible to predict user behavior and traffic demand. I have presented the main difference between designing a passive or active distributed antenna system. Additionally I have listed investor’s technical requirements and verification process. The goal of every in-building system design is to fulfill given requirements as well to allow future upgrades and implementation of new technologies. Some of them are listed in the conclusion. mobilni sistemi v zgradbah distribuiran antenski sistem mobilni sistem v dvorani Stožice In-building systems distributed antenna system IBS basketball arena Stožice true false false Slovenski jezik Angleški jezik Diplomsko delo 2016-06-16 08:51:24 2016-06-16 08:51:25 2022-08-01 23:25:52 0000-00-00 00:00:00 2016 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 34661 Kejzar_Rok_-_Nacrtovanje_mobilnih_sistemov_v_zgradbah.pdf Kejzar_Rok_-_Nacrtovanje_mobilnih_sistemov_v_zgradbah.pdf 1 06B75F9A993840240A29CC035EE878ED 2157ca60af489ba61bead6972cef9564749477923e8fe4a23f9a18aee7d2e865 4a96e1e9-a1ae-11eb-a523-00155dcfd717 20.500.12556/rul/0e16a824-23bf-4588-a45d-ed8bd9d0d882 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=86527 Fakulteta za elektrotehniko 0 0 0
