Ukusetshenziswa kwama-Duplexer kuma-Indoor Distribution Systems

Ngenxa yesidingo esikhulayo sokuxhumana kweselula nokuphepha komphakathi, izinhlelo ze-antenna ezisabalaliswa zangaphakathi (i-DAS) zisetshenziswa kabanzi ezindaweni ezinjengezikhumulo zezindiza, imigwaqo engaphansi komhlaba, izibhedlela, nezindawo ezinkulu zezentengiselwano ukuze kubhekwane nezindawo eziyimpumputhe ezitholakala endlini kanye nokuncishiswa kwamasignali. Phakathi kwezingxenye eziningi ezibalulekile ezinhlelweni ze-DAS, ii-duplexeriyingxenye ebalulekile nebalulekile.

Ii-duplexerumsebenzi oyinhloko ukunika amandla amasignali e-uplink ne-downlink ukuze abelane nge-antenna efanayo, ahlukanise ngempumelelo amasignali amabili ngomklamo wokuzihlukanisa kakhulu ukuvimbela ukuphazamiseka. Lesi sici sinikeza izinzuzo ezilandelayo ezinhlelweni ze-DAS:

Isibalo se-antenna esincishisiwe: Izinti ezabiwe zinciphisa kakhulu inkimbinkimbi yokufaka nezindleko zekhebula;

Ikhwalithi yesignali ethuthukisiwe: Igcina ukuxhumana okuzinzile ezindaweni eziningi ezijwayelekile, ezinamabhendi amaningi;

Isekela ukuthunyelwa kwezimo eziningi: Kungakhathaliseki ukuthi ku-DAS yokuphepha komphakathi, izakhiwo zezentengiselwano, noma amanethiwekhi abiwe wabasebenzisi abaningi,ama-duplexersikwazi ukusebenza ngokwethembeka.

Ezinhlelweni zokuxhumana zokuphepha komphakathi,ama-duplexersqinisekisa ukuxhumana okubushelelezi kwe-VHF/UHF kwamaphoyisa, abacimi bomlilo, kanye nezokuxhumana eziphuthumayo zezokwelapha. Ezindaweni ezinkulu zezentengiselwano, zehlisa izinyawo zemishini futhi zithuthukise ukufana kokufakwa. Ezindaweni eziyinkimbinkimbi njengezikhumulo zezindiza nezitimela ezihamba ngaphansi,ama-duplexersukusiza ukuzuza ukuhlukaniswa okuphumelelayo kanye nokuxhumana okungenamthungo kwama-multi-operator, amasignali amabhendi amaningi.

Ngokuhlukaniswa okuphezulu, ukulahleka kokufakwa okuphansi, amandla okubamba amandla aqinile, kanye nomklamo owenziwe ngokwezifiso,ama-duplexersqinisekisa ukusebenza okuphezulu kokusebenza kwezinhlelo ze-DAS ezindaweni lapho amazinga amaningi, njenge-LTE, 5G, nokuphepha komphakathi, ehlala ndawonye. Ziyizici ezibalulekile zesimanje zokuxhumana zasendlini.
