Isimiso sokusebenza se-booster yesignali yeselula

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 amasignali omakhalekhukhwini ancike ekusakazweni kwamagagasi kagesi ukuze kusungulwe 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, ngaphansi komhlaba. amaphrojekthi okuvikela umoya womphakathi, iziteshi zesitimela, njll., kulezi zindawo, amasignali omakhalekhukhwini awakwazi ukufinyelelwa futhi nomakhalekhukhwini abakwazi ukusetshenziswa.

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.

umakhalekhukhwini wesiginali booster

Umgomo oyisisekelo womsebenzi wayo uthi: sebenzisa i-antenna eya phambili (i-antenna yomnikeli) ukuze uthole isignali ye-downlink yesiteshi sesisekelo kusiphindaphinda, ukhulise isignali ewusizo nge-amplifier yomsindo ophansi, ucindezele isignali yomsindo kusiginali, futhi uthuthukise. isilinganiso se-signal-to-noise (isilinganiso se-S/N). ); bese iguqulelwa phansi ibe isignali yefrikhwensi ephakathi, ihlungwe ngesihlungi, ikhuliswe kumafrikhwensi amaphakathi, bese iguqulelwa phezulu ibe yifrikhwensi yomsakazo ngokugudluka kwamaza, ikhuliswe isikhulisi samandla, bese idluliselwa esiteshini esihambayo ngothi olubuyela emuva. (i-antenna yokudlulisela kabusha); ngesikhathi esifanayo, i-antenna yangemuva isetshenziswa. Isiginali ye-uplink yesiteshi esihambayo iyamukelwa, futhi icutshungulwa isixhumanisi sokukhulisa i-uplink endleleni ephambene: okungukuthi, idluliselwa esiteshini esiyisisekelo ngokusebenzisa i-amplifier yomsindo ophansi, i-downconverter, isihlungi, i-amplifier ephakathi, i-amplifier. i-upconverter, kanye ne-amplifier yamandla. Ngalo mklamo, ukuxhumana kwezindlela ezimbili phakathi kwesiteshi sesisekelo kanye nesiteshi seselula 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. Ama-antenna e-Omnidirectional angasetshenziswa endlini, futhi ubude bokufakwa bungamamitha angu-2-3 (Inani le-antenna nendawo incike endaweni engaphakathi nesakhiwo sangaphakathi), kufanele kufakwe ithikithi elilodwa elingaphakathi ukuze kube nobubanzi obungavinjwanga bangaphakathi obungaphansi kwesikwele esingu-300. amamitha, izimpondo ezi-2 zasendlini ziyadingeka ebangeni elingamamitha-skwele angama-300-500, kanti ezi-3 ziyadingeka ebangeni elingama-500 kuya 800 square metres.

3. Ukufakwa kwe-booster yesignali yeselula: ngokuvamile ifakwa 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 lokuphakelayo kwe-booster yesiginali yomsakazo nethelevishini (i-cable TV) ngu-75Ω, kodwa i-booster yesignali yeselula iyimboni yezokuxhumana, futhi indinganiso yayo ingu-50Ω, futhi ukuvinjelwa okungalungile ziwohloka 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, ngokusemthethweni ukuxazulula izinkinga zesignali umakhalekhukhwini! NgiyacelaXhumana nathingenkonzo yamakhasimende.
