Sonke besilapho: ungena kwi-elevator, iibha zesignali zefowuni yakho ziyehla ziye kwi-zero, uze ushiywe ujonge isikrini esingenanto—uphoswa yifowuni yomthengi, usapho lujonge ukungena, okanye ungakwazi nokufowunela uncedo ukuba i-elevator ima ngequbuliso. Ii-elevator zizinto ezisebenza nzima kwizakhiwo zanamhlanje, kodwa iindonga zazo zesinyithi kunye nokwakhiwa kwazo kwekhonkrithi zizenza zibe yimingxunya emnyama yesignali, kwaye yinto ebangela ukuba umntu angafanele ayinyamezele.
Iindaba ezimnandi?isinyusi sesignali yefowuni yeliftiayilocebo lobuchwephesha elimangalisayo—licebo elilula elisebenzayo, ukuba uyazi indlela yokukhetha elichanekileyo. Emva kweminyaka yokunceda izakhiwo zisombulule le ngxaki, ndiyachaza isizathu sokuba iilifti zibulale isignali, indlela eziIzikhuseli zesignali zefowuni ye-3g 4giyasebenza ngokwenene, kwaye iimpazamo ezenziwa ngumntu wonke xa ethenga enye—akukho magama angaqhelekanga, yintetho nje yokwenyani ukuze ufumane umyalezo opheleleyo, nokuba ziindawo ezixineneyo ezithe nkqo.
Okokuqala, masicacise eyona ntsomi inkulu: ukulahleka kwesignali yelifti akukokuba inqaba yeseli ikude kakhulu. Konke kumayelana nokukhusela ngokwasemzimbeni. Isignali yefowuni yakho ngamaza e-electromagnetic kuphela, kwaye xa loo maza efika kwikhabhathi ye-elevator yesinyithi evaliweyo, awadluli nje—agxuma eludongeni lwesinyithi njengebhola kumatshini we-pinball, kwaye oko kuncinci okungajikiyo kutsalwa yikhonkrithi etyebileyo. Okubi nangakumbi, ii-elevator zenza into ebizwa ngokuba yi-resonant cavity effect: amaza ayabanjwa ngaphakathi kwikhabhathi, egxumagxuma emva nangaphambili de amandla awo aphele ngokupheleleyo. Yiyo loo nto nokuba unemivalo epheleleyo ngaphandle kwe-elevator, awusebenzi kwangoko xa iingcango zivaliwe—ayisiyongxaki yenethiwekhi, yingxaki yefiziksi.
Ngoko ke njaniizikhuseli zesignali zeliftiNgaba uyoyisa le ngxaki yefiziksi? Konke malunga nenkqubo elula yokudlulisa umbane enamanyathelo amathathu, kwaye ayisiyosayensi yerokhethi. Okokuqala, i-antenna yangaphandle ebhekisa kwicala ifakelwe kwi-elevator shaft okanye eluphahleni lwesakhiwo, ibhekiswe ngqo kwinqaba yeseli ekufutshane. Le antenna ibamba nesona signali sincinci esijikelezayo kwisakhiwo—isignali ebuthathaka kangangokuba ifowuni yakho ayinakukwazi ukuyithatha yodwa. Okulandelayo, eso signali sibuthathaka siya kwiyunithi ye-booster, eyandisa amandla ayo kwaye ihluze zonke iingxaki eziphazamisayo ezivela kwiinkqubo zolawulo ze-elevator, izibane, kunye nezinye izixhobo ze-elektroniki zokwakha.
Eli nyathelo libalulekile: akupheleli nje ekwenzeni isignali ibe phezulu, kodwa kukuyenza icoceke. Okokugqibela, i-antenna encinci ejikelezayo ngaphakathi kwikhabhathi yelifti isasaza isignali eyonyusiweyo, ehluzwayo kuyo yonke ikona yemoto.
Nantsi into efunekayo, nangona kunjalo: ayizizo zonkeizikhuseli zesignali zelifti zenziwe ngokulinganayo, kwaye i-intanethi igcwele iindlela ezingabizi kakhulu. Ndithethe nabaphathi bezakhiwo abaninzi kunye nabanini bezindlu abachithe imali kwi-booster kodwa bafumanisa ukuba ayisebenzi, okanye ibangela iingxaki ezingaphezulu kunezo zisombululayo. Ingxaki ayikokuba itekhnoloji imbi—kukuba abantu bathenga ngokusekelwe kwixabiso okanye kwiinkcukacha ezingacwangciswanga, kungekhona kwiimpawu ezintathu ezibalulekileyo kwiilifti. Masizihlalutye ezi zinto, kuba zahlukile phakathi kwe-booster esebenza iminyaka emininzi kunye neyo iphelela kwinkunkuma.
Okokuqala kukuhambelana kwebhendi. Ukuba uthenga isixhobo sokunyusa esixhasa ibhendi enye okanye ezimbini kuphela, uzibeka esichengeni sokungaphumeleli. Namhlanje, sonke sisebenzisa i-4G, 5G, kwane-2G/3G kwiifowuni ezisisiseko, kwaye wonke umphathi wenethiwekhi usebenzisa iibhendi ezahlukeneyo. Ndibone abantu bethenga ibhendi engabizi kakhulu.isixhasi sebhendi enyeukwenza nje iifowuni, kodwa baqonde ukuba abanakukwazi ukulayisha iphepha lewebhu okanye ukuthumela umyalezo—oko kuyawuphelisa ngokupheleleyo loo njongo. Ii-elevator boosters ezilungileyo zixhasa iibhendi ezininzi (i-tri-band, i-five-band) kwaye zisebenza nazo zonke iinkampani ezinkulu, ngoko akufuneki utshintshe isixhobo xa i-5G isasazeka ngakumbi okanye utshintsha ababoneleli. Lulungiso oluza kwenziwa kube kanye, alulo uncedo lwexeshana.
Okwesibini nguulawulo lokuzuza oluzenzekelayo (AGC). Abantu abaninzi bacinga"Inzuzo ephezulu = isignali engcono",” kodwa leyo yeyona mpazamo imbi onokuyenza nge-elevator booster. Ukwanda kakhulu kubangela ukugcwala kwesignali, okukhokelela kwisandi esicaphukisayo esingashukumiyo okanye “sempendulo” kwiifowuni—sikubiza ngokuba “kukuguquguquka.” Kunokuphazamisa nezinye izixhobo ze-elektroniki zesakhiwo okanye inqaba yeseli yasekuhlaleni, oku kukufumana isikhalazo kumphathi wakho. I-booster elungileyo ayigcini nje ngokufaka i-maximum gain kwiyunithi encinci; inetekhnoloji ye-AGC elungisa amandla esignali.ngokuzenzekelayoUkuba isignali yetower inamandla ngolunye usuku kwaye ibuthathaka ngolunye usuku, isixhasi siyahlengahlengiswa—akukho kulungiswa ngesandla, akukho mthwalo omninzi, isignali nje ezinzileyo necacileyo ngalo lonke ixesha.
Okwesithathu kuyilo oluchasene nokuphazamiseka. Iilifti ziindawo ezinengxolo yemiqondiso—phakathi kwemoto, iphaneli yokulawula, kunye nokukhanya, kukho ukuphazamiseka okukhulu kwe-electromagnetic okujikelezayo. Ii-booster ezingabizi kakhulu azisebenzisi ukhuselo kunye nokucoca okufunekayo ukuthintela le ngxolo, ngoko ke isignali yakho ephakanyisiweyo ifana neyasekuqaleni.izikhuseli zesignali zisebenzisa isikhuselo sesinyithi kwiyunithi kunye neesekethe zesihluzo eziphambili ukunqanda konke oko kuphazamiseka, ngoko ke nokuba ilifti ihamba ngesantya esiphezulu, isignali yakho ihlala iqinile. Ungaskrola, utsalele umnxeba, okanye uthumele umyalezo ngaphandle kokuqandisa okanye ukuwisa—yiyo loo ntointo eyenziwa yi-booster elungileyo.
A isixhasi sesignali yelifti elungileyoAyikuko nje ukuskrola imidiya yoluntu kwilifti; imalunga nokuba nomgca wokunceda xa kukho into engalunganga, malunga nokungaphoswa yifowuni ebalulekileyo, kunye nokwenza iilifti zesakhiwo sakho zisebenze njengoko kufanele. Isakhiwo ngasinye sanamhlanje sifanelwe luphawu oluthembekileyo kuzo zonke iikona, kuquka nezo zithe nkqo.
Ukuba ujongene nendawo engenanto yakwenza neempawu ezingafunekiyo kwiilifti zesakhiwo sakho—nokuba ungumphathi wepropathi, umnini-shishini, okanye umnini-ndlu kwi-condo—akusekho mfuneko yokuba unyamezele loo nto.Cofa apha qhagamshelana nathingezantsi ngemeko yakho: zingaphi iilifti onazo? Yeyiphi ingxaki enkulu ojongene nayo (iifowuni eziphosiweyo, akukho signali konke konke, idatha ecothayo)? Ndiza kwabelana nawe ngohlobo lwe-booster oyifunayo, kwaye ndichaze indlela yokuphepha iimpazamo ezenziwa ngabanye abantu. Akukho ntengiso, icebiso elinyanisekileyo nje elivela kumntu olungise le ngxaki kwizakhiwo ezininzi.
