Abaphindayo Indlela Yokusebenza

Yini ephindayo

I-repeater iyisisetshenziswa esidluliswayo sokuxhumana ngomsakazo esinomsebenzi wokwamukela nokukhulisa amasignali enethiwekhi yomakhalekhukhwini. Isetshenziswa kakhulu ezindaweni lapho isiginali yesiteshi sesisekelo ibuthakathaka kakhulu. Ikhulisa isignali yesiteshi bese iyidlulisela ezindaweni ezikude nezibanzi, ngaleyo ndlela yandise ukusabalala kwenethiwekhi. ububanzi.

Iziphindaphinda ziyisixazululo esilungile sokunweba ukusabalala kwamanethiwekhi okuxhumana. Uma kuqhathaniswa neziteshi eziyisisekelo, zinezinzuzo zesakhiwo esilula, ukutshalwa kwezimali okuncane, nokufaka kalula. Zingasetshenziswa kakhulu ezindaweni eziyizimpumputhe nasezindaweni ezibuthakathaka okunzima ukuzihlanganisa, njengenxanxathela yezitolo nezikhumulo zezindiza. , iziteshi, izinkundla, imigwaqo ehamba ngaphansi, imigwaqo emikhulu nezinye izindawo ukuze kuthuthukiswe ikhwalithi yokuxhumana nokuxazulula izinkinga ezifana nezingcingo eziyehlisiwe.

WorkingPi-rinciple

Umsebenzi oyisisekelo wokuphindaphinda amandla esignali ye-RF. Umgomo oyisisekelo womsebenzi wayo ukusebenzisa i-antenna eya phambili (i-antenna yomnikeli) ukuthola isignali ye-downlink yesiteshi sesisekelo kusiphindaphinda, ukhulise isignali ewusizo ngokusebenzisai-amplifier yomsindo ophansi, cindezela isignali yomsindo kusiginali, futhi uthuthukise isilinganiso sesignali-kuya-nomsindo (S/N); Bese iguqulelwa phansi ibe isignali yefrikhwensi emaphakathi, ihlungwe nge-aisihlungi, ikhuliswe imvamisa emaphakathi, bese iguqulwa ibe yifrikhwensi yomsakazo, ikhuliswe isikhulisi samandla, futhi idluliselwe esiteshini esihambayo ngothi olubuyela emuva (i-antenna yokudlulisela kabusha); ngasikhathi sinye, yemukelwa i-antenna engemuva Isiginali ye-uplink yesiteshi esiphathwayo icutshungulwa isixhumanisi sokukhulisa i-uplink endleleni ephambene: okungukuthi, idlulai-amplifier yomsindo ophansi, isiguquli esiphansi,isihlungi, i-amplifier emaphakathi, isiguquli esiphezulu, kanye nesikhulisi samandla bese sidluliselwa esiteshini esiyisisekelo, ngaleyo ndlela kuzuzwe ukuxhumana phakathi kwesiteshi sesisekelo nesiteshi esihambayo. Ukuxhumana okubili.

Uhlobo Lokuphindaphinda

(1) Isiphindaphindi sokuxhumana kweselula se-GSM

I-GSM repeater iyindlela yokuxazulula inkinga yezindawo eziyizimpumputhe zesignali ezibangelwa ukumbozwa kwesiteshi sesisekelo. Ukusetha abaphindayo akukwazi nje ukuthuthukisa ukufakwa, kodwa futhi kunciphisa kakhulu izindleko zokutshala imali eziteshini eziyisisekelo.

(2) Isiteshi se-CDMA esiphindaphinda ukuxhumana kwamaselula

Isiphindaphinda se-CDMA singasusa izindawo zethunzi zangaphandle zesignali zasendaweni emadolobheni ezibangelwa umthelela wezakhiwo eziphakeme. Abaphindayo be-CDMA banganweba ukufakwa kweziteshi eziyisisekelo ze-CDMA futhi bonge kakhulu utshalomali ekwakhiweni kwenethiwekhi ye-CDMA.

(3) Isiteshi se-GSM/CDMA optical fiber repeater

I-fiber optic relay yokuxhumana yeselula ephindaphindayo iqukethe izingxenye ezimbili: umshini oseduze eduze nesiteshi sesisekelo kanye nomshini oqhelile oseduze nendawo yokumboza. I-optical fiber repeater inemisebenzi efana ne-broadband, ukukhethwa kwebhendi, ukukhetha ibhendi, nokukhetha imvamisa.
