Lesi sihloko sinikeza umbono jikelele wezingxenye zangaphakathi ze-elekthronikhi ze-repeater yesignali yeselula. Bambalwa abakhiqizi abadalula izingxenye zangaphakathi ze-repeater yabo yesignali kubathengi. Eqinisweni, ukwakheka kanye nekhwalithi yalezi zingxenye zangaphakathi kudlala indima ebalulekile ekusebenzeni okuphelele kwe-isiphindaphindi sesignali yeselula.
Uma ungathanda incazelo elula yokuthi i-repeater yesignali yeselula isebenza kanjani,Chofoza lapha.
Izimiso Eziyisisekelo Zokuphindaphinda Kwesignali Ehambayo
Njengoba kuboniswe kumdwebo ongenhla, isimiso esiyisisekelo sokuphindaphinda kwesignali yeselula ukukhulisa izimpawu ngezigaba. Iziphindaphindi zesignali yeselula zanamuhla emakethe zidinga izigaba eziningi zokukhulisa okungenamandla ukuze kufezwe inzuzo efiselekayo yokukhipha. Ngakho-ke, inzuzo kumdwebo ongenhla imelela iyunithi eyodwa yokuzuza. Ukuze kufinyelelwe inzuzo yokugcina, kudingeka izigaba eziningi zokukhulisa.
Nasi isingeniso samamojula ajwayelekile atholakala ku-repeater yesignali yeselula:
1. Imodyuli Yokwamukela Isignali
Imojuli yokwamukela inesibopho sokwamukela izimpawu zangaphandle, ngokuvamile ezivela eziteshini eziyisisekelo noma kuma-antenna. Ibamba izimpawu zomsakazo ezithunyelwa yisiteshi esiyisisekelo bese iziguqula zibe izimpawu zikagesi ezingacutshungulwa yi-amplifier. Imojuli yokwamukela ngokuvamile ihlanganisa:
Izihlungi: Lezi zisusa izimpawu zemvamisa ezingafuneki futhi zigcina amabhendi emvamisa yesignali yeselula adingekayo.
Isikhulisi Somsindo Ophansi (i-LNA): Lokhu kwandisa isignali engenayo ebuthakathaka ngenkathi kunciphisa umsindo owengeziwe.

2. Imodyuli Yokucubungula Isignali
Iyunithi yokucubungula isignali ikhulisa futhi ilungise isignali etholakele. Ngokuvamile ifaka:
I-Modulator/Demodulator (I-Modem): Lokhu kuguqula futhi kunciphise isignali ukuqinisekisa ukuthi ihambisana nezinqubo zokuxhumana ezijwayelekile.
Iprosesa Yesignali Yedijithali (i-DSP): Inesibopho sokucubungula nokuthuthukisa isignali ngempumelelo, ukuthuthukisa ikhwalithi yesignali nokunciphisa ukuphazamiseka.
Ukulawula Ukuthola Okuzenzakalelayo (AGC): Kulungisa ukuzuza kwesignali ukuqinisekisa ukuthi kuhlala kumazinga afanele—kugwenywe kokubili ubuthakathaka besignali kanye nokukhulisa ngokweqile okungase kubangele ukuphazamiseka noma ukuphazamisa amanye amadivayisi.
3. Imodyuli Yokukhulisa
I-power amplifier (PA) ikhulisa amandla esignali ukuze yandise ububanzi bayo bokumboza. Ngemva kokucutshungulwa kwesignali, i-power amplifier yandisa isignali ibe namandla adingekayo futhi iyidlulisele nge-antenna. Ukukhetha i-power amplifier kuncike kumandla adingekayo nendawo yokumboza. Kunezinhlobo ezimbili eziyinhloko:
Ama-Linear Amplifier: Lawa agcina ikhwalithi nokucaca kwesiginali ngaphandle kokuphazamiseka.
Ama-Amplifiers Angewona Aqondile: Asetshenziswa ezimweni ezikhethekile, ngokuvamile ekumbozweni kwendawo ebanzi, yize engase abangele ukuphazamiseka kwesignali.
4. Amamojula Okulawula Impendulo Nokuvimbela Ukuphazamiseka
Imojuli Yokucindezela Impendulo: Uma i-amplifier idlulisela isignali enamandla kakhulu, ingabangela impendulo ku-antenna eyamukelayo, okuholela ekuphazamisekeni. Amamojula okucindezela impendulo asiza ekuqedeni lokhu kuziphazamisa.
I-Isolation Module: Ivimbela ukuphazamiseka okuhlangene phakathi kwezimpawu zokwamukela nezokudlulisa, iqinisekisa ukusebenza kahle kwe-amplifier.
Ukucindezela Umsindo kanye Nezihlungi: Nciphisa ukuphazamiseka kwesignali yangaphandle, uqinisekise ukuthi isignali ihlala ihlanzekile futhi inamandla.
5. Imodyuli Yokudlulisa Isignali
Imodyuli Yokudlulisa: Le module ithumela isignali ecutshunguliwe nekhulisiwe nge-antenna yokudlulisa endaweni embozwe, iqinisekisa ukuthi amadivayisi eselula athola isignali ethuthukisiwe.
Umlawuli Wamandla Okudlulisa: Ulawula amandla okudlulisa ukuze kuvinjelwe ukukhulisa ngokweqile, okungabangela ukuphazamiseka, noma ukukhulisa kancane, okungaholela ezimpawini ezibuthakathaka.
I-Antenna Eqondisa: Ukuze uthole ukumbozwa kwesignali okugxile kakhulu, i-antenna eqondisa ingasetshenziswa esikhundleni se-omnidirectional, ikakhulukazi ukumbozwa kwendawo enkulu noma ukuthuthukiswa kwesignali.
6. Imodyuli Yokuphakelwa Kwamandla
Iyunithi Yokunikezela Ngogesi: Ihlinzeka ngogesi ozinzile ku-repeater yesiginali, ngokuvamile nge-AC-to-DC converter, ukuqinisekisa ukuthi isebenza kahle ngaphansi kwezimo ze-voltage ezahlukahlukene.
Imodyuli Yokuphatha Amandla: Amadivayisi aphezulu angafaka nezici zokuphatha amandla ukuze kuthuthukiswe ukusebenza kahle kwamandla futhi kwandiswe isikhathi sokuphila kwedivayisi.
7. Imodyuli Yokushabalalisa Ukushisa
Uhlelo Lokupholisa: Ama-repeater esignali akhiqiza ukushisa ngesikhathi sokusebenza, ikakhulukazi ama-power amplifier nezinye izingxenye ezinamandla amakhulu. Uhlelo lokupholisa (njengama-heat sink noma amafeni) lusiza ukugcina izinga lokushisa elisebenza kahle ukuvimbela ukushisa ngokweqile kanye nomonakalo kudivayisi.
8. Iphaneli Yokulawula Nezinkomba
Iphaneli Yokulawula: Ezinye iziphindaphindi zesignali yeselula ziza nephaneli yokubonisa evumela abasebenzisi ukulungisa izilungiselelo, ukulungisa ukusebenza kahle, nokuqapha uhlelo.
Izinkomba ze-LED: Lezi zibani zibonisa isimo sokusebenza kwedivayisi, okuhlanganisa amandla esignali, amandla, kanye nesimo sokusebenza, okusiza abasebenzisi ukuthi banqume ukuthi i-repeater isebenza kahle yini.
9. Amachweba Okuxhumana
Imbobo Yokufaka: Isetshenziselwa ukuxhuma ama-antenna angaphandle (isb., izixhumi zohlobo lwe-N noma uhlobo lwe-F).
Imbobo Yokukhipha: Yokuxhuma ama-antenna angaphakathi noma ukudlulisa amasignali kwamanye amadivayisi.
Imbobo Yokulungisa: Ezinye iziphindaphindi zingase zifake amambobo okulungisa izilungiselelo zokuzuza kanye nemvamisa.
10. Umklamo Wokuvalela Nokuvikela
Isembozo se-repeater ngokuvamile senziwe ngensimbi, esiza ukuvikela ekuphazamisekeni kwangaphandle nokuvimbela ukuphazamiseka kwe-electromagnetic (EMI). Amanye amadivayisi aphinde abe nesembozo esingangeni manzi, esingangeni uthuli, noma esingangenwa ukushaqeka ukuze simelane nezimo zangaphandle noma eziyinselele.
Izingxenye Zangaphakathi-isiphindaphindi sesignali yeselula yezentengiselwano
I-repeater yesignali yeselula ithuthukisa amasignali ngomsebenzi ohlanganisiwe wala mamojula. Uhlelo luthola futhi lukhulise isignali ngaphambi kokudlulisa isignali eqinisiwe endaweni embozwe kuyo. Uma ukhetha i-repeater yesignali yeselula, kubalulekile ukuqinisekisa ukuthi ama-frequency band ayo, amandla, kanye nokuzuza kufanelana nezidingo zakho ezithile, ikakhulukazi ezindaweni eziyinkimbinkimbi njengemigudu noma izitezi ezingaphansi komhlaba lapho ukumelana nokuphazamiseka kanye namakhono okucubungula amasignali kubalulekile khona.
Ngakho-ke, ukukhethaumenzi othembekile wokuphindaphinda isignali yeselulakuyisihluthulelo.I-Lintratek, eyasungulwa ngo-2012, ineminyaka engaphezu kwengu-13 yesipiliyoni ekukhiqizeni iziphindaphindi zesignali—kusukela kumayunithi okuhlala kuya kwezentengiselwano, kufaka phakathi iziphindaphindi ze-fiber optic kanye neziteshi zokusakaza eziqondile. Le nkampani ithola izingxenye zekhwalithi ephezulu zemikhiqizo yayo, okuqinisekisa ukusebenza okuthembekile.
