20.500.12556/RUL-83710 Fiksni brezžični širokopasovni sistemi Fixed Broadband Wireless Systems Diplomska naloga opisuje fiksne brezžične širokopasovne sisteme. Opisani so sistemi, ki so jih pred dolgimi leti razvili z namenom distribucije televizijskih programov in sistemi, ki jih uporabljamo danes in omogočajo dvosmerni prenos interneta ter telefonije preko interneta. Bolj podrobno so opisani tudi sistemi, ki jih uporabljamo oz. tisti, ki jih bomo v Sloveniji še uporabljali. Fiksni širokopasovni brezžični sistemi se razlikujejo glede na proizvajalca in na ponudnika storitve, zato so na kratko predstavljene osnovne lastnosti in zgradba najbolj osnovnega sistema, iz katerega izhajajo nadaljnji sistemi. Uporabljajo se lahko različne frekvence, zato je opisano tudi, kako reagirajo različne frekvence v brezžičnem prostoru. Predstavljeni so različni sistemi, ki delujejo na različnih frekvenčnih območjih. Zaradi hitrega širjenja fiksnih brezžičnih širokopasovnih sistemov so se začele pojavljati motnje med njimi in drugimi sistemi na določenih frekvenčnih območjih. Opisane so tudi najpogostejše motnje in v katerih frekvenčnih območjih se pojavljajo. Slovenija je ena od držav, ki uporablja te sisteme za distribucijo dvosmernega širokopasovnega prenosa. Predstavljena so frekvenčna območja, ki so namenjena fiksnim širokopasovnim brezžičnim sistemom na slovenskem ozemlju in nekatera pravila, ki jih morajo operaterji upoštevati. This thesis describes fixed broadband wireless systems. Also described are systems that have been developed for distributing television programs and systems that are being currently used for bi-directional internet and IP-telephony transmission. The systems that are used in Slovenia are described in more details. Fixed broadband wireless systems can be very different, depending on the manufacturer and service provider. Because of that, the most common system from which all others originate, is described in the thesis. The systems can use different frequencies and because of that, the thesis describes how different frequencies react in the wireless environment. Systems that operate on various frequency bands are also described. The number of interferences between systems at certain frequencies has grown due to the rapid expansion of fixed wireless broadband systems. Also described in the thesis are the most common interferences and in which frequency bands they occur. Slovenia is one of the countries that use those systems for bi-directional broadband distribution. Frequency bands that are used for fixed wireless broadband systems and certain rules service providers on Slovenian territory are obliged to follow are also introduced in the thesis. brezžični širokopasovni prenos fiksni brezžični sistemi frekvenčna območja brezžični prenos televizije brezžični prenos interneta modulacije in standardi sistemi na slovenskem ozemlju. wireless broadband transfer fixed wireless systems frequency bands wireless television transmitter wireless internet transmitter modulations and standards systems on Slovenian territory. true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-06-23 13:55:01 2016-06-23 13:55:04 2022-08-02 00:13:23 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 34473 Trcek_David_-_Fiksni_brezzicni_sirokopasovni_sistemi.pdf Trcek_David_-_Fiksni_brezzicni_sirokopasovni_sistemi.pdf 1 18C7AA28D34ACA5620E7842B9D5CA4CB 1264d1a733bbff4cdeacfc2c9f64eba58bee31f7887d5be7ac39888aaf82e9d8 5400f331-a1ae-11eb-a523-00155dcfd717 20.500.12556/rul/ddf6e34d-330c-4c6a-bd3d-a32a508e32f7 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=86747 Fakulteta za elektrotehniko 0 0 0
