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 yokuvaleka kwezakhiwo, kwezinye izakhiwo ezinde, amagumbi angaphantsi kunye nezinye iindawo, ezinye iindawo zokuthenga, iindawo zokutyela, iindawo zokuzonwabisa ezinje ngekaraoke, sauna kunye ne-massage, phantsi komhlaba. Iiprojekthi zokhuselo lomoya woluntu, izikhululo zikaloliwe ezingaphantsi komhlaba, njl.njl., kwezi ndawo, imiqondiso yeselula ayinakufikelelwa kwaye iiselfowuni azikwazi ukusetyenziswa.
I-Lintratek yefowuni yeselula ye-booster ye-boosterinokusombulula ezi ngxaki kakuhle kakhulu.Okoko nje inkqubo ye-booster yefowuni ephathwayo ifakwe kwindawo ethile, abantu banokufumana uphawu oluhle lweselfowuni kuyo yonke indawo njengoko ugubungela yonke indawo apho.Nantsi i-pic yokubonisa ukuba isebenza njani i-booster yeselula.
Umgaqo osisiseko womsebenzi wayo ngulo: sebenzisa i-eriyali eya phambili (i-antenna yomxhasi) ukufumana isiginali ye-downlink yesikhululo sesiseko kwi-repeater, ukhulise isiginali eluncedo ngesandisi-lizwi esiphantsi, ucinezele umqondiso wengxolo kwisiginali, kwaye uphucule. umlinganiselo wesignali ukuya kwingxolo (S/N ratio).);emva koko iguqulelwe phantsi ukuya kwisiginali yefrikhwensi ephakathi, ihluzwe sisihluzo, inyuswe kwifrikhwensi ephakathi, kwaye emva koko iguqulelwe kumaza onomathotholo ngokuguquguquka, ikhuliswe sisikhulisi samandla, kwaye idluliselwe kwisikhululo esiphathwayo nge-eriyali engasemva. (i-eriyali yokudluliselwa kwakhona);ngelo xesha, i-eriyali engasemva isetyenziswa.Isiginali ye-uplink yesitishi esihambayo ifunyenwe, kwaye icutshungulwa ngekhonkco lokukhulisa i-uplink ecaleni kwendlela echaseneyo: oko kukuthi, idluliselwa kwisikhululo esisezantsi ngesandisi-sandi esiphantsi, i-downconverter, icebo lokucoca, i-amplifier ephakathi, i-amplifier. upconverter, kunye neamplifier 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 buziimitha ezi-2-3 (Isixa se-eriyali kunye nendawo ixhomekeke kwindawo yangaphakathi kunye nesakhiwo sangaphakathi), i-eriyali enye kuphela yangaphakathi kufuneka ifakwe kuluhlu lwangaphakathi olungathintelekiyo olungaphantsi kwama-300 square. Iimitha, ii-eriyali ezi-2 zangaphakathi ziyafuneka kuluhlu lwe-300-500 square metres, kwaye ezi-3 ziyafuneka kuluhlu lwama-500 ukuya kuma-800 eemitha zesikwere.
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 (yi-cable TV) yi-75Ω, kodwa i-booster yesignali yefowuni yeselula yimboni yonxibelelwano, kwaye umgangatho wayo ngu-50Ω, kunye nokuphazamiseka okungalunganga kuya . ukuwohloka kwezalathi 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, ii-eriyali ezimbini zohlulwe ngeemitha ezi-8 ukuphepha ukuzivuselela.
Lintratek, ngobuchule ukusombulula iingxaki zesiginali yefowuni ephathwayo!NdiyacelaQhagamshelana nathingenkonzo yabathengi.
