Abaphindayo Indlela Yokusebenza

Yintoni umntu ophindayo

Ukuphinda-phinda sisixhobo sonxibelelwano lukanomathotholo esinomsebenzi wokufumana kunye nokukhulisa imiqondiso yenethiwekhi yeselula.Isetyenziswa ikakhulu kwiindawo apho umqondiso wesikhululo sesiseko ubuthathaka kakhulu.Ikhulisa umqondiso wesikhululo sesiseko kwaye emva koko iwudlulisele kwiindawo ezikude nezibanzi, ngokwenjenjalo yandisa i-network coverage.ububanzi.

Abaphindaphindayo sisisombululo esona sisiso sokwandisa ukhuselo lothungelwano lonxibelelwano.Xa kuthelekiswa nezikhululo ezisisiseko, zineenzuzo zesakhiwo esilula, utyalo-mali oluncinci, kunye nokufakwa lula.Zingasetyenziswa ngokubanzi kwiindawo ezingaboniyo kunye neendawo ezibuthathaka ekunzima ukuzigubungela, ezifana neevenkile ezinkulu kunye nezikhululo zeenqwelomoya., izitishi, amabala emidlalo, i-subways, uhola wendlela kunye nezinye iindawo zokuphucula umgangatho wonxibelelwano kunye nokusombulula iingxaki ezifana neefowuni ezihlayo.

WukwenzaPrinciple

Umsebenzi osisiseko wophinda-phindwayo sisimboli samandla sophawu lweRF.Umgaqo osisiseko womsebenzi wayo kukusebenzisa i-eriyali eya phambili (i-antenna yomxhasi) ukufumana isiginali ye-downlink yesikhululo esisezantsi kwisiphindaphindi, ukukhulisa umqondiso oluncedo ngokusebenzisaiamplifier yengxolo ephantsi, cinezela umqondiso wengxolo kwisignali, kwaye uphucule umlinganiselo we-signal-to-noise ratio (S / N);Emva koko iguqulelwe phantsi ibe yisignali yefrikhwensi ephakathi, ihluzwe ngeisihluzo, ikhuliswe yi-frequency intermediate, kwaye emva koko i-up-converted to frequency radio, ikhuliswe yi-amplifier yamandla, kwaye idluliselwe kwisikhululo esihambayo nge-antenna yangasemva (i-antenna yokubuyisela);Kwangaxeshanye, yamkelwa yi-eriya engasemva Isignali ye-uplink yesikhululo esihambayo isenziwa likhonkco lokukhulisa i-uplink ecaleni kwendlela echaseneyo: oko kukuthi, idlulaiamplifier yengxolo ephantsi, phantsi-converter,isihluzo, i-mid-amplifier, i-up-converter, kunye ne-amplifier yamandla kwaye emva koko idluliselwe kwisikhululo sesiseko, ngaloo ndlela ifezekisa unxibelelwano phakathi kwesikhululo sesiseko kunye nesikhululo esihambayo.Indlela ezimbini zonxibelelwano.

Uhlobo lokuphinda

(1) I-GSM yonxibelelwano lweselula oluphindayo

I-GSM repeater yindlela yokusombulula ingxaki yeendawo ezingaboniyo zesignali ezibangelwa kukhuseleko lwesiseko sesikhululo.Ukuseta abaphindayo akunakuphucula kuphela ukugubungela, kodwa kunciphise kakhulu iindleko zotyalo-mali kwizikhululo ezisisiseko.

(2) Isikhululo sokuphinda unxibelelwano oluphathwayo lweCDMA

I-CDMA ephindayo inokuphelisa indawo yethunzi yangaphandle yemiqondiso yasekhaya ezixekweni ezibangelwa yimpembelelo yezakhiwo eziphakamileyo.Abaphindayo be-CDMA banokwandisa ukhuseleko lwezikhululo ze-CDMA kwaye basindise kakhulu utyalo-mali kulwakhiwo lwe-CDMA network.

(3) GSM/CDMA optical fiber repeater station

I-fiber optic relay ye-mobile communication repeater iqulethwe ngamacandelo amabini: umatshini osondeleyo osondeleyo kwisikhululo sesiseko kunye nomatshini okude kufuphi nommandla wokugubungela.I-fiber optical repeater inemisebenzi efana ne-broadband, ukhetho lwebhendi, ukhetho lwebhendi, kunye nokukhethwa kwamaza.
