I-booster yesiginali yeselula, eyaziwa nangokuthi i-repeater, yakhiwe izimpondo zokuxhumana, i-RF duplexer, isikhulisi somsindo ophansi, i-mixer, i-ESC attenuator, isihlungi, isikhulisi samandla nezinye izakhi noma amamojula ukwenza izixhumanisi zokukhulisa i-uplink ne-downlink.
I-booster yesignali yeselula iwumkhiqizo oklanyelwe ngokukhethekile ukuxazulula indawo eyimpumputhe yesignali yomakhalekhukhwini. Njengoba izimpawu zomakhalekhukhwini zithembele ekusakazweni kwamagagasi kagesi ukuze kutholakale ukuxhumana, ngenxa yokuvinjwa kwezakhiwo, kwezinye izakhiwo ezinde, amagumbi angaphansi nezinye izindawo, ezinye izitolo ezinkulu, izindawo zokudlela, izindawo zokuzijabulisa ezifana ne-karaoke, i-sauna kanye ne-massage, amaphrojekthi okuvikela umoya ongaphansi komhlaba, iziteshi zesitimela, njll.
I-Lintratek yeselula yesignali ye-boosteringaxazulula lezi zinkinga kahle kakhulu. Uma nje isistimu ye-booster yesignali yeselula ifakwe endaweni ethile, abantu bangathola isignali yeselula enhle yonke indawo njengoba uhlanganisa yonke indawo lapho. Nasi isithombe ukuze sibonise ukuthi isebenza kanjani i-booster yeselula.
Umgomo oyisisekelo womsebenzi wayo uthi: sebenzisa i-antenna eya phambili (i-antenna yomnikeli) ukuze uthole isignali ye-downlink yesiteshi sesisekelo kusiphindaphinda, ukhulise isignali ewusizo ngeamplifier yomsindo ophansi, ucindezele isignali yomsindo kusiginali, futhi uthuthukise isilinganiso sesignali-kuya-nomsindo (isilinganiso se-S/N). ); bese iguqulelwa phansi ibe isignali yefrikhwensi ephakathi, ihlungwe ngesihlungi, ikhuliswe kumafrikhwensi amaphakathi, bese iguqulelwa phezulu kufrikhwensi yomsakazo ngokugudluzwa imvamisa, ikhuliswe isikhulisi samandla, bese idluliselwa esiteshini esihambayo ngothi olubuyela emuva (i-antenna yokudlulisela kabusha); ngesikhathi esifanayo, i-antenna yangemuva isetshenziswa. Isignali ye-uplink yesiteshi esihambayo iyamukelwa, futhi icutshungulwa isixhumanisi sokukhulisa i-uplink endleleni ephambene: okungukuthi, idluliselwa esiteshini sesisekelo ngokusebenzisa isikhulisi somsindo ophansi, i-downconverter, isihlungi, i-amplifier ephakathi, i-upconverter, ne-amplifier yamandla. Ngalo mklamo, ukuxhumana okubili phakathi kwesiteshi sesisekelo kanye nesiteshi esihambayo kungenzeka.
Imiyalelo yokufaka nezinyathelo zokuphepha:
1. Ukukhetha imodeli: Khetha imodeli efanelekile ngokuya ngekhava kanye nezakhiwo zokwakha.
2. Uhlelo lokusabalalisa uthingo: Sebenzisa izimpondo ze-Yagi eziqonde ngqo ngaphandle, futhi isiqondiso sezimpondo kufanele zikhombe esiteshini esiyisisekelo sokudlulisa kaningi ngangokunokwenzeka ukuze uzuze umphumela ongcono kakhulu wokwamukela. Izimpondo ze-Omnidirectional zingasetshenziswa endlini, futhi ukuphakama kokufakwa kungamamitha angu-2-3 (Inani le-antenna nendawo incike endaweni engaphakathi nesakhiwo sangaphakathi), i-antenna eyodwa kuphela yasendlini edinga ukufakwa uhla lwangaphakathi olungavinjelwe olungaphansi kwamamitha-skwele angama-300, izimpondo ezi-2 zasendlini ziyadingeka ebangeni elingamamitha-skwele angama-300 kuya ku-300 kuya ku-300 kuya ku-50. 800 square metres.
3. Ukufakwa kwe-booster yesignali yocingo lweselula: kuvame ukufakwa endaweni engaphezu kwamamitha angu-2 ukusuka phansi. Ibanga phakathi kwendawo yokufaka okokusebenza kanye nezinti ezingaphakathi nangaphandle kufanele zihanjiswe ngebanga elifushane kakhulu (ngekhebula ende, ukuncishiswa kwesignali kukhulu) ukuze kuzuzwe umphumela ongcono kakhulu.
4. Ukukhethwa kwezintambo: izinga lesiphakeli se-booster yesignali yomsakazo nethelevishini (i-cable TV) ngu-75Ω, kodwa i-booster yesiginali yeselula imboni yezokuxhumana, futhi izinga layo lingu-50Ω, futhi ukuvinjelwa okungalungile kuzolimaza izinkomba zesistimu. Ukuqina kocingo kunqunywa ngokuya ngesimo sangempela esizeni. Uma ikhebuli iba yinde, intambo iba yinde ukuze kuncishiswe ukuncipha kwesignali. Ukusebenzisa intambo engu-75Ω ukwenza umsingathi nentambo kungafani kuzonyusa igagasi lokuma futhi kubangele izinkinga eziningi zokuphazamiseka. Ngakho-ke, ukukhethwa kocingo kufanele kuhlukaniswe ngokwemboni.
Isignali ethunyelwe uthi lwendlu ayikwazi ukutholwa uthi olungaphandle, oluzobangela ukuzithokozisa. Ngokuvamile, izimpondo ezimbili zihlukaniswa ngamamitha angu-8 ukugwema ukuzivusa.
I-Lintratek, ukuxazulula izinkinga zesignali yeselula ngokusemthethweni! NgiyacelaXhumana nathingenkonzo yamakhasimende.
