I-booster yefowuni ephathwayo, ekwabizwa 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.Ekubeni iimpawu zefowuni eziphathwayo zixhomekeke ekusasazweni kwamaza ombane ukuseka unxibelelwano, ngenxa yokuvalwa kwezakhiwo, kwezinye izakhiwo ezide, amagumbi angaphantsi kunye nezinye iindawo, ezinye iindawo zokuthenga, iindawo zokutyela, iindawo zokuzonwabisa ezifana nekaraoke, 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 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 ngulo: sebenzisa i-eriyali eya phambili (i-antenna yomxhasi) ukufumana isignali ye-downlink yesikhululo sesiseko kwi-repeater, ukhulise umqondiso oluncedo ngesandisi-lizwi esiphantsi, ucinezele umqondiso wengxolo kwisignali, 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 yesikhululo esihambayo ifunyenwe, kwaye icutshungulwe ngekhonkco lokukhulisa i-uplink ecaleni kwendlela echaseneyo: oko kukuthi, idluliselwe kwisikhululo esisezantsi ngesandisi-sandi esiphantsi, i-downconverter, isihluzi, 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 zingasetyenziselwa ngaphakathi, kwaye ubude bofakelo buziimitha ezi-2-3 (Ubungakanani be-eriyali kunye nendawo ixhomekeke kwindawo yangaphakathi kunye nesakhiwo sangaphakathi), i-eriyali enye kuphela yangaphakathi kufuneka ifakwe kuluhlu lwangaphakathi olungathintelekiyo olungaphantsi kwe-300 square. Iimitha, ii-eriyali ezi-2 zangaphakathi ziyafuneka kuluhlu lwe-300-500 square metres, kwaye ezi-3 ziyafuneka kuluhlu lwe-500 ukuya kwi-800 yeemitha 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, kunye nomgangatho wayo yi-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, i-eriyali ezimbini zohlulwe ngeemitha ezi-8 ukuphepha ukuzivuselela.
Lintratek, ngobuchule ukusombulula iingxaki zesiginali yefowuni ephathwayo!NdiyacelaQhagamshelana nathingenkonzo yabathengi.
