I-booster yefowuni yeselula, eyaziwa ngokuba yi-repeater, yenziwe ngee-eriyali zonxibelelwano, i-RF duplexer, iamplifier yengxolo ephantsi, i-mixer, i-ESC attenuator, isihluzi, i-amplifier yamandla kunye namanye amacandelo okanye iimodyuli zokwenza i-uplink kunye ne-downlink yokwandisa amakhonkco.
I-booster yefowuni yeselula yimveliso eyenzelwe ngokukodwa ukusombulula indawo eyimfama yesiginali yefowuni ephathwayo. Kuba imiqondiso yefowuni ephathwayo ixhomekeke ekusasazweni kwamaza ombane ukuseka unxibelelwano, ngenxa yokuvalwa kwezakhiwo, kwezinye izakhiwo ezinde, amagumbi angaphantsi kunye nezinye iindawo, iindawo zokuthenga, iindawo zokutyela, iindawo zokuzonwabisa ezinje ngekaraoke, sauna kunye ne-massage, iiprojekthi zokhuselo lomoya ophantsi komhlaba, izikhululo zikaloliwe ezingaphantsi komhlaba, njl.
I-Lintratek yefowuni yeselula ye-booster ye-boosterinokusombulula ezi ngxaki kakuhle kakhulu. Okoko nje inkqubo ye-booster yefowuni ephathwayo ifakwe kwindawo ethile, abantu banokufumana umqondiso weselfowuni elungileyo kuyo yonke indawo njengoko ugubungela yonke indawo apho. Nantsi i-pic yokubonisa ukuba isebenza njani i-booster yeselula.
Umgaqo osisiseko womsebenzi wayo kukuba: sebenzisa i-antenna yangaphambili (i-antenna yomxhasi) ukufumana isignali ye-downlink yesikhululo sesiseko kwi-repeater, ukhulise isignali eluncedo ngokusebenzisa i-amplifier yomsindo ophantsi, ucinezele umqondiso wengxolo kwisignali, kwaye uphucule umlinganiselo we-signal-to-noise ratio (S / N ratio). ); emva koko i-down-converted ibe yi-intermediate frequency signal, ihluzwe sisihluzo, inyuswe kwi-frequency ephakathi, kwaye emva koko iguqulelwe kwi-frequency yerediyo ngokutshintsha rhoqo, ikhuliswe yi-amplifier yamandla, kwaye idluliselwe kwisikhululo esihambayo nge-eriyali engasemva (i-antenna yokubuyisela); ngelo xesha, i-eriyali engasemva isetyenziswa. Isignali ye-uplink yesitishi esihambayo ifunyenwe, kwaye iqhutywe yi-uplink amplification link ecaleni kwendlela echaseneyo: oko kukuthi, idluliselwe kwisikhululo sesiseko ngokusebenzisa i-amplifier yomsindo ophantsi, i-downconverter, i-filter, i-intermediate amplifier, i-upconverter, kunye ne-amplifier yamandla. Ngolu yilo, unxibelelwano lweendlela ezimbini phakathi kwesikhululo esisisiseko kunye nesikhululo esiphathwayo sinokwenzeka.
Imiyalelo yokufakela kunye nezilumkiso:
1. Ukukhetha imodeli: Khetha imodeli efanelekileyo ngokugubungela kunye nezakhiwo zokwakha.
2. Isicwangciso sokusasazwa kwe-antenna: Sebenzisa i-antenna ye-Yagi ngaphandle, kwaye isalathiso se-eriyali kufuneka sibhekiselele kwisikhululo sokuhambisa isiseko kangangoko kunokwenzeka ukuphumeza umphumo ongcono wokwamkela. Ii-eriyali ze-Omnidirectional zingasetyenziswa ngaphakathi, kwaye ubude bofakelo buzimitha ezi-2-3 (Isixa se-eriyali kunye nendawo sixhomekeke kwindawo yangaphakathi kunye nolwakhiwo lwangaphakathi), i-eriyali enye kuphela yangaphakathi ekufuneka ifakwe kuluhlu lwangaphakathi olungathintelekiyo olungaphantsi kwe-300 square metres, ii-eriyali ezi-2 zangaphakathi ziyafuneka kuluhlu lweemitha ezingama-300 ukuya kwe-300 kunye ne-50. 800 square metres.
3. Ufakelo lwe-booster yefowuni yeselula: ifakwe ngokubanzi kwiimitha ezingaphezu kwe-2 ngaphezu komhlaba. Umgama phakathi kwendawo yofakelo lwesixhobo kunye ne-eriyali yangaphakathi nangaphandle kufuneka ihanjiswe kunye nomgama omfutshane (ngobude bentambo, ubukhulu be-signal attenuation) ukufezekisa umphumo ongcono.
4. Ukukhethwa kweengcingo: umgangatho we-feeder ye-booster yesignali yerediyo kunye nomabonwakude (i-cable TV) yi-75Ω, kodwa i-booster ye-mobile phone i-booster yonxibelelwano, kunye nomgangatho wayo ngu-50Ω, kwaye i-impedance engalunganga iya kuhlahloka izikhombisi zenkqubo. Ubunzima bocingo bunqunywe ngokwemeko yangempela kwisayithi. Okukhona intambo inde, kokukhona ucingo lutyebileyo lokunciphisa ukucutha umqondiso. Ukusebenzisa i-75Ω ucingo ukwenza umamkeli kunye nocingo zihambelane ziyakwandisa amaza okuma kwaye kubangele iingxaki zokuphazamiseka. Ngoko ke, ukhetho locingo kufuneka luhlulwe ngokweshishini.
Isibonakaliso esithunyelwe yi-antenna yangaphakathi ayinakufunyanwa yi-antenna yangaphandle, eya kubangela ukuzikhukhumeza. Ngokuqhelekileyo, i-eriyali ezimbini zohlulwe ngeemitha ezi-8 ukuphepha ukuzivuselela.
Lintratek, ngobuchule ukusombulula iingxaki zesiginali yefowuni ephathwayo! NdiyacelaQhagamshelana nathingenkonzo yabathengi.
