Lesi sihloko sinikeza ukubuka konke kwezingxenye ze-elekthronikhi zangaphakathi zokuphinda isignali yeselula. Bambalwa abakhiqizi abadalula izingxenye zangaphakathi zezimpawu zabo eziphindayo kubathengi. Eqinisweni, ukwakheka kanye nekhwalithi yalezi zingxenye zangaphakathi kudlala indima ebalulekile ekusebenzeni kukonke kwe-ophinda isignali yeselula.
Uma ungathanda incazelo elula yokuthi isiphindaphinda sesiginali yeselula sisebenza kanjani,Chofoza lapha.
Izimiso Eziyisisekelo Zokuphinda Isiginali Yeselula
Njengoba kukhonjisiwe kumdwebo ongenhla, umgomo oyisisekelo wokuphinda isignali yeselula ukukhulisa amasignali ngezigaba. Iziphindaphinda zesiginali yeselula yesimanje emakethe zidinga izigaba eziningi zokukhulisa inzuzo ephansi ukuze kuzuzwe inzuzo edingekayo. Ngakho-ke, inzuzo kumdwebo ongenhla imelela iyunithi eyodwa nje yokuzuza. Ukuze ufinyelele inzuzo yokugcina, izigaba eziningi zokukhulisa ziyadingeka.
Nasi isingeniso samamojula ajwayelekile atholakala kusiphindaphinda isiginali yeselula:
1. Imojula Yokwamukela Isiginali
Imojula yokwamukela inesibopho sokwamukela amasignali angaphandle, ngokuvamile avela eziteshini eziyisisekelo noma izimpondo. Ithwebula amasignali omsakazo asakazwa yisiteshi esiyisisekelo futhi iwaguqule abe amasignali kagesi iamplifier engawacubungula. Imojula yokwamukela ngokuvamile ihlanganisa:
Izihlungi: Lezi zisusa amasiginali wefrikhwensi engadingeki futhi zigcine amabhendi efrikhwensi yesiginali yeselula.
Isihlelamsindo esiphansi (LNA): Lokhu kukhulisa isignali engenayo engenamandla kuyilapho kunciphisa umsindo owengeziwe.

2. Imojula Yokucubungula Isignali
Iyunithi yokucubungula isignali ikhulisa futhi ilungise isignali eyamukelwe. Ngokuvamile kuhlanganisa:
I-Modulator/I-Demodulator (I-Modemu): Lokhu kushintsha futhi kwehlise isignali ukuze kuqinisekiswe ukuthi ihambisana nezinqubo zokuxhumana ezijwayelekile.
Iphrosesa Yesiginali Yedijithali (i-DSP): Inesibopho sokucutshungulwa kwesignali okuphumelelayo nokuthuthukisa, ukuthuthukisa ikhwalithi yesiginali kanye nokunciphisa ukuphazamiseka.
I-Automatic Gain Control (AGC): Ilungisa ukuzuza kwesignali ukuze kuqinisekiswe ukuthi ihlala ingaphakathi kwamaleveli alungile—igwema kokubili ubuthakathaka besignali nokukhulisa okudlulele okungase kubangele ukuzithikamezeka noma ukuphazamisa amanye amadivayisi.
3. I-Amplification Module
Isikhulisi samandla (i-PA) sithuthukisa amandla esignali ukuze sinwebe ububanzi bayo bokuhlanganisa. Ngemva kokucubungula isignali, isikhulisi samandla sikhulisa isignali emandleni adingekayo futhi siyidlulisele ngothi. Ukukhethwa kwe-amplifier yamandla kuncike emandleni adingekayo kanye nendawo yokumboza. Kunezinhlobo ezimbili eziyinhloko:
Ama-Amplifaya Alayini: Lezi zigcina ikhwalithi nokucaca kwesiginali ngaphandle kokuhlanekezela.
Ama-Amplifaya Angaqondile: Asetshenziswa ezimweni ezikhethekile, ngokuvamile ukuze amboze indawo ebanzi, nakuba angabangela ukuhlanekezelwa kwesignali ethile.
4. Ukulawula impendulo kanye namamojula okuvimbela ukuphazamiseka
Imojuli Yokucindezelwa Kwempendulo: Uma i-amplifier idlulisela isignali enamandla kakhulu, ingase ibangele impendulo othini olwamukelayo, okuholela ekuphazamisekeni. Amamojula okucindezela impendulo asiza ekuqedeni lokhu kuziphazamisa.
I-Isolation Module: Ivimbela ukuphazamiseka phakathi kokwamukela nokudlulisa amasignali, iqinisekisa ukusebenza okufanele kwe-amplifier.
Ukucindezelwa Komsindo Nezihlungi: Yehlisa ukuphazamiseka kwesignali yangaphandle, uqinisekisa ukuthi isignali ihlala ihlanzekile futhi iqinile.
5. I-Signal Transmission Module
Imojula Yokudluliswa: Le mojula ithumela isignali ecutshunguliwe nekhulisiwe ngothi oludluliselayo endaweni yokumboza, iqinisekisa ukuthi amadivaysi eselula athola isignali ethuthukisiwe.
I-Transmit Power Controller: Ilawula amandla okudlulisela ukuvimbela ukukhuliswa ngokweqile, okungabangela ukuphazamiseka, noma ukukhulisa kancane, okungaholela kumasignali abuthakathaka.
I-Directional Antenna: Ukuze uthole ukumbozwa kwesignali okugxilwe kakhulu, i-antenna eqondisayo ingasetshenziswa esikhundleni se-omnidirectional, ikakhulukazi ukufakwa kwendawo enkulu noma ukuthuthukiswa kwesignali.
6. Imojula Yokuhlinzeka Ngamandla
Iyunithi Yokunikezela Ngamandla: Ihlinzeka ngokunikezwa kwamandla okuzinzile kusiphindaphinda isiginali, ngokuvamile ngokusebenzisa isiguquli se-AC-to-DC, siqinisekisa ukuthi sisebenza kahle ngaphansi kwezimo zamandla kagesi ezihlukene.
Imojula Yokuphatha Amandla: Amadivayisi asezingeni eliphezulu angase futhi afake izici zokuphatha amandla ukuze kuthuthukiswe ukusebenza kahle kwamandla nokwandisa ubude bempilo yedivayisi.
7. I-Heat Dissipation Module
Isistimu Yokupholisa: Abaphindayo besignali bakhiqiza ukushisa ngesikhathi sokusebenza, ikakhulukazi izikhulisamandla zamandla nezinye izingxenye zamandla aphezulu. Isistimu yokupholisa (njengamasinki okushisa noma amafeni) isiza ukugcina izinga lokushisa elilungile lokusebenza ukuvimbela ukushisa ngokweqile kanye nokulimala kudivayisi.
8. Iphaneli yokulawula kanye nezinkomba
Iphaneli Yokulawula: Ezinye iziphindi zesiginali yeselula ziza nephaneli yokubonisa evumela abasebenzisi ukuthi balungise izilungiselelo, balungise ukusebenza kahle, futhi baqaphe isistimu.
Izinkomba ze-LED: Lezi zibani zibonisa isimo sokusebenza kwedivayisi, okuhlanganisa amandla esignali, amandla, nesimo sokusebenza, okusiza abasebenzisi ukunquma ukuthi isiphindayo sisebenza kahle yini.
9. Izimbobo zokuxhuma
Imbobo yokufaka: Isetshenziselwa ukuxhuma izimpondo zangaphandle (isb., uhlobo lwe-N noma izixhumi zohlobo luka-F).
Imbobo yokuphumayo: Okokuxhuma izinti zangaphakathi noma ukudlulisa amasignali kwamanye amadivaysi.
Imbobo yokulungisa: Abanye abaphindayo bangafaka izimbobo zokulungisa inzuzo kanye nezilungiselelo zokuvama.
10. Idizayini Ebiyelwe kanye Nokuvikela
Okuvalekile okuphindaphindayo kuvame ukwenziwa ngensimbi, esiza ukuvikela ekuphazanyisweni kwangaphandle futhi kuvimbele ukuphazamiseka kwe-electromagnetic (EMI). Amanye amadivaysi futhi anezindawo ezivalekile ezingangeni manzi, ezingangenwa uthuli, noma ezingethuki ukuze zimelane nezindawo zangaphandle noma eziyinselele.
Izingxenye Zangaphakathi-commercial isignali mobile repeater
Isiphindaphinda sesignali yeselula sithuthukisa amasignali ngomsebenzi ohlanganisiwe walawa mamojula. Isistimu ithola futhi ikhulise isignali ngaphambi kokudlulisa isignali eqinisiwe endaweni yokumboza. Uma ukhetha isiphindaphindi sesiginali yeselula, kubalulekile ukuqinisekisa ukuthi amabhendi ayo okuvama, amandla, kanye nokuzuza kufana nezidingo zakho ezithile, ikakhulukazi ezindaweni eziyinkimbinkimbi njengamathaneli noma amagumbi angaphansi lapho ukumelana nokuphazamiseka namandla okucubungula isignali kubalulekile.
Ngakho-ke, ukukhethaumenzi onokwethenjelwa wesiginali yeselulaukhiye.I-Lintratek, eyasungulwa ngo-2012, ineminyaka engaphezu kwengu-13 yokuhlangenwe nakho kokukhiqiza amasignali aphindaphindayo-kusuka endaweni yokuhlala kuya kumayunithi okuhweba, okuhlanganisa ama-fiber optic repeaters kanye neziteshi zokusakaza eziqondile. Inkampani ithola izingxenye zekhwalithi ephezulu zemikhiqizo yazo, iqinisekisa ukusebenza okuthembekile.
