Izikhulisi zesignali yeselulaAmadivayisi aklanyelwe ukuthuthukisa amandla okwamukelwa kwesignali yeselula. Abamba amasignali abuthakathaka futhi awakhulise ukuze athuthukise ukuxhumana ezindaweni ezinokwamukelwa okubi noma izindawo ezifile. Kodwa-ke, ukusetshenziswa kabi kwala madivayisi kungaholela ekuphazamisekeni kweziteshi zeselula.
Isiteshi Sesisekelo Seselula
Izimbangela Zokuphazamiseka
Amandla Okukhipha Adlulele:Abanye abakhiqizi bangase bandise amandla okukhipha ama-booster abo ukuze bahlangabezane nezidingo zomsebenzisi, okungabangela ukuphazamiseka komsindo kanye nokungcola komshayeli okuthinta ukuxhumana kwesiteshi esiyisisekelo. Ngokuvamile, imininingwane yobuchwepheshe yalezi zi-booster—njengesibalo somsindo, isilinganiso samagagasi amile, i-intermodulation ye-third-order, kanye nokuhlunga imvamisa—ayihambisani nezindinganiso zomthetho.
Ukufakwa Okungafanele:Ama-booster esignali yeselula angagunyaziwe avame ukufakwa kabi, okungenzeka ahlangane nezindawo zokumboza zenkampani futhi avimbele iziteshi eziyisisekelo ekudluliseni amasignali ngempumelelo.
Ikhwalithi Yedivayisi Ehlukahlukene:Ukusebenzisa izikhulisi zesignali zeselula ezisezingeni eliphansi ezinokuhlunga okubi kungabangela ukuphazamiseka okukhulu eziteshini eziyisisekelo zezinkampani eziseduze, okuholela ekunqanyulweni okuvamile kwabasebenzisi abaseduze.
Ukuphazamisana:Ama-booster amaningi esignali yeselula angaphazamisana, adale umjikelezo omubi ophazamisa ukuxhumana ezindaweni zasendaweni.
Izincomo Zokunciphisa Ukuphazamiseka
-Sebenzisa amadivayisi aqinisekisiwe ahlangabezana nezindinganiso zomthetho nezokulawula.
- Cela ochwepheshe ukuthi bafake futhi balinganise imishini ukuqinisekisa ukuthi ibekwe kahle futhi i-engeli ifanelekile.
-Ukulungisa nokuhlola njalo ukuqinisekisa ukusebenza kahle.
-Xhumana nenkampani yakho yenethiwekhi ukuze uthole ukuhlolwa kochwepheshe kanye nezixazululo uma kuvela izinkinga zesiginali.
Izici ze-AGC kanye ne-MGC zama-Mobile Signal Boosters
I-AGC (Automatic Gain Control) kanye ne-MGC (Manual Gain Control) yizici ezimbili ezivamile zokulawula i-gain ezitholakala kuma-booster esignali eselula.
1.AGC (Ukulawula Ukuzuza Okuzenzakalelayo):Lesi sici silungisa ngokuzenzakalelayo inzuzo ye-booster ukuze sigcine isignali yokukhipha ngaphakathi kobubanzi obubekiwe. Uhlelo lwe-AGC luvame ukuba ne-variable gain amplifier kanye ne-feedback loop. I-feedback loop ikhipha ulwazi lwe-amplitude kusuka kusignali yokukhipha futhi ilungisa inzuzo ye-amplifier ngokufanele. Lapho amandla esignali yokufaka ekhuphuka, i-AGC inciphisa inzuzo; ngokuphambene nalokho, lapho isignali yokufaka incipha, i-AGC ikhulisa inzuzo. Izingxenye ezibalulekile ezihilelekile zifaka:
-Isitholi se-AGC:Iqapha ubukhulu besiginali yokuphuma kwe-amplifier.
-Isihlungi Sokushelela Esidlula Kancane:Iqeda izingxenye ezivame kakhulu nomsindo ovela esignalini etholakele ukuze ikhiqize i-voltage yokulawula.
-Isekethe Yokulawula I-Voltage:Ikhiqiza i-voltage yokulawula esekelwe kusignali ehlungiwe ukuze ilungise inzuzo ye-amplifier.
-I-Gate Circuit kanye ne-DC Amplifier:Lokhu kungafakwa futhi ukuze kuthuthukiswe futhi kuthuthukiswe ukulawula inzuzo.
2.MGC (Ukulawula Ukuzuza Ngesandla):Ngokungafani ne-AGC, i-MGC ivumela abasebenzisi ukuthi balungise ngesandla inzuzo ye-amplifier. Lesi sici singaba usizo ezimweni ezithile lapho ukulawulwa kwenzuzo okuzenzakalelayo kungahlangabezani nezidingo ezithile, okuvumela abasebenzisi ukuthi bathuthukise ikhwalithi yesignali kanye nokusebenza kwedivayisi ngokulungiswa ngesandla.
Empeleni, i-AGC kanye ne-MGC zingasetshenziswa ngokuzimela noma ngokubambisana ukuze zinikeze isisombululo sokukhulisa isignali esiguquguqukayo. Isibonelo, ezinye izithuthukisi zesignali yeselula ezithuthukisiwe zifaka kokubili ukusebenza kwe-AGC kanye ne-MGC, okuvumela abasebenzisi ukushintsha phakathi kwezindlela ezizenzakalelayo nezesandla ngokusekelwe ezindaweni ezahlukahlukene zesignali kanye nezidingo zomsebenzisi.
Izinto Okucatshangelwayo Ngomklamo we-AGC kanye ne-MGC
Uma uklama ama-algorithm e-AGC, izici ezifana nezici zesignali kanye nezingxenye ze-RF front-end zibalulekile. Lokhu kufaka phakathi izilungiselelo zokuqala ze-AGC gain, ukutholwa kwamandla esignali, ukulawula i-AGC gain, ukwenza ngcono isikhathi njalo, ukuphathwa komsindo phansi, ukulawula i-gain saturation, kanye nokwenza ngcono ububanzi obuguquguqukayo. Ngokubambisana, lezi zinto zinquma ukusebenza kanye nokusebenza kahle kohlelo lwe-AGC.
Kuma-booster esignali eselula, ukusebenza kwe-AGC kanye ne-MGC kuvame ukuhlanganiswa nobunye ubuchwepheshe bokulawula okuhlakaniphile, njenge-ALC (Automatic Level Control), i-ISO self-oscillation lining, i-uplink idle shutdown, kanye ne-automatic power shutoff, ukuhlinzeka ngezixazululo zokukhulisa isignali kanye nokumboza ezisebenza kahle nezithembekile. Lezi zici ziqinisekisa ukuthi i-amplifier ingalungisa ngokuzenzakalelayo isimo sayo sokusebenza ngokusekelwe ezimweni zangempela zesignali, ithuthukise ukumbozwa kwesignali, inciphise ukuphazamiseka kweziteshi eziyisisekelo, futhi ithuthukise ikhwalithi yokuxhumana iyonke.
