Sonke sike saba lapho: ungena ekhefini, imigoqo yesignali yocingo lwakho yehla iye ku-zero, bese usala ubheke isikrini esingenalutho—uphuthelwe ucingo lweklayenti, ungena emndenini, noma ungakwazi ngisho nokufona ucele usizo uma ikhefini ima ngokungazelelwe. Ama-lifti ayizisebenzi ezisebenza kakhulu ezakhiweni zesimanje, kodwa izindonga zawo zensimbi kanye nokwakhiwa kwawo kokhonkolo kuzenza zibe yimigodi emnyama yesignali, futhi kuyinto ecasulayo okungekho muntu okufanele ayibekezelele.
Izindaba ezinhle?i-elevator yeselula yesignali yokukhulisaakuyona icebo lobuchwepheshe elisezingeni eliphezulu—yisisombululo esilula esisebenzayo, uma wazi ukuthi ungayikhetha kanjani efanele. Ngemva kweminyaka eminingi yokusiza izakhiwo ukuxazulula le nkinga, ngichaza ukuthi kungani ama-lifti ebulala isignali, ukuthi lezi zintoIzikhulisi zesignali zeselula ze-3g 4gempeleni kuyasebenza, kanye namaphutha enziwa yiwo wonke umuntu lapho ethenga eyodwa—akukho magama alula, ukukhuluma nje kwangempela ukuze uthole isignali ephelele, ngisho nasezindaweni eziqinile eziqondile.
Okokuqala, ake sicacise inganekwane enkulu: ukulahleka kwesignali ye-elevator akukhona ukuthi umbhoshongo weseli uqhele kakhulu. Konke kumayelana nokuvikela ngokomzimba. Isignali yocingo lwakho ingamagagasi kagesi, futhi lapho lawo magagasi eshaya i-elevator cab yensimbi evaliwe, awamane nje adlule—agxuma ezindongeni zensimbi njengebhola emshinini we-pinball, futhi lokho okuncane okungagxumanga kudonswa ukhonkolo ojiyile. Okwenza kube kubi nakakhulu, ama-elevator adala okuthile okubizwa ngokuthi umphumela we-resonant cavity: amagagasi abhajwa ngaphakathi kwe-cab, agxumagxuma emuva naphambili kuze kube yilapho amandla awo echithwa ngokuphelele. Yingakho noma ngabe unezingodo ezigcwele ngaphandle kwe-elevator, usuke ungaxhunyiwe ku-inthanethi ngokushesha uma iminyango ivaliwe—akuyona inkinga yenethiwekhi, kuyindaba yefiziksi.
Ngakho-ke kanjaniizikhulisi zesignali ze-elevatorUkunqoba le nkinga yefiziksi? Konke kumayelana nohlelo olulula lwezinyathelo ezintathu, futhi akuyona isayensi yerokhethi. Okokuqala, i-antenna yangaphandle eqondisayo ifakwe ku-elevator shaft noma ophahleni lwesakhiwo, iqondiswe ngqo embhoshongweni weseli oseduze. Le antenna ibamba ngisho nesignali encane kakhulu entantayo esakhiweni—isignali ebuthakathaka kangangokuthi ifoni yakho ayikwazi ukuyithatha yodwa. Okulandelayo, leso signali esibuthakathaka siya kuyunithi ye-booster, ekhulisa amandla ayo futhi ihlunge konke ukuphazamiseka okungcolile okuvela ezinhlelweni zokulawula ze-elevator, izibani, kanye nezinye izinto zikagesi zokwakha.
Lesi sinyathelo sibalulekile: akukhona nje ukwenza isignali ibe nomsindo omkhulu, kodwa futhi kuyenza ihlanzeke. Okokugcina, i-antenna encane eqondisa yonke indawo ngaphakathi kwekhebhini ye-elevator isakaza ekhulisa isignali, ihlunge kuwo wonke amakhona emoto.
Nansi inkinga, nokho: akuzona zonkeizikhulisi zesignali ze-elevator zakhiwe ngokulinganayo, futhi i-inthanethi igcwele izinketho ezishibhile. Ngikhulume nabaphathi bezakhiwo abaningi kanye nabaninikhaya abachithe imali ku-booster kodwa bathola ukuthi ayisebenzi, noma ibangela izinkinga eziningi kunalokho ezikuxazululayo. Inkinga akukhona ukuthi ubuchwepheshe bubi—ukuthi abantu bathenga ngokusekelwe entengo noma ezicini ezingahleliwe, hhayi izici ezintathu ezibalulekile ngempela kuma-lifti. Ake sihlukanise lokhu, ngoba umehluko phakathi kwe-booster esebenza iminyaka eminingi kanye neyokugcina ilahlekile.
Okokuqala ukuhambisana kwebhendi. Uma uthenga i-booster esekela ibhendi elilodwa noma amabili kuphela, uzibeka engcupheni yokwehluleka. Namuhla, sonke sisebenzisa i-4G, 5G, ngisho ne-2G/3G ukuze sithole izingcingo eziyisisekelo, futhi inkampani ngayinye isebenzisa amabhendi ahlukene. Ngibone abantu bethenga i-eshibhile.i-booster yebhendi eyodwaukwenza izingcingo nje, kodwa baqaphele ukuthi abakwazi ukulayisha ikhasi lewebhu noma ukuthumela umyalezo—okuphazamisa ngokuphelele injongo. Ama-elevator booster amahle kakhulu asekela ama-band amaningi (ama-tri-band, ama-five-band) futhi asebenza nazo zonke izinkampani ezinkulu, ngakho akudingeki ukuthi ushintshe idivayisi uma i-5G isabalala kakhulu noma ushintsha abahlinzeki. Kuyisisombululo esisodwa, hhayi i-band-aid yesikhashana.
Okwesibiliukulawula inzuzo okuzenzakalelayo (i-AGC). Abantu abaningi bacabanga ukuthi"Inzuzo ephezulu = isignali engcono",” kodwa lelo yiphutha elibi kakhulu ongalenza nge-elevator booster. Ukwanda kakhulu kubangela ukugcwala kwesignali, okuholela kulowo msindo ocasulayo we-static noma “wempendulo” ezingcingweni—sikubiza ngokuthi “ukuguquguquka.” Kungaphazamisa ngisho nezinye izinto zikagesi zesakhiwo noma umbhoshongo weseli wendawo, kukwenze ukhale kumphathi wakho. I-booster enhle ayigcini nje ngokufaka inzuzo enkulu eyunithi encane; inobuchwepheshe be-AGC obulungisa amandla esignalingokuzenzakalelayoUma isignali yombhoshongo inamandla ngolunye usuku futhi ibuthakathaka ngolunye usuku, i-booster iyavumelana nezimo—akukho zinguquko ezenziwa ngesandla, akukho ukulayisha ngokweqile, isignali nje ezinzile necacile njalo.
Okwesithathu ukwakheka okulwa nokuphazamiseka. Ama-lifti ayizindawo ezinomsindo zezimpawu—phakathi kwenjini, iphaneli yokulawula, kanye nokukhanya, kukhona ukuphazamiseka okuningi kwe-electromagnetic okuzulazulayo. Ama-booster ashibhile ayakweqa ukuvikela nokuhlunga okudingekayo ukuvimba lo msindo, ngakho-ke isignali yakho ephakanyisiwe ifana neyasekuqaleni.ama-booster esignali asebenzisa isivikelo sensimbi kuyunithi kanye nezifunda zokuhlunga ezithuthukisiwe ukuze aqede konke lokho kuphazamiseka, ngakho-ke noma ilifti ihamba ngesivinini esigcwele, isignali yakho ihlala iqinile. Ungaskrola, ushayele ucingo, noma uthumele umyalezo ngaphandle kokuma noma ukuwa—yilokholokho okwenziwa yi-booster enhle.
A isikhuthazi sesignali esihle se-elevatorakukhona nje ukuskrola ezinkundleni zokuxhumana esitobhini; kumayelana nokuba nomzila wokuphila uma kukhona okungahambi kahle, mayelana nokungaphuthelwa ucingo olubalulekile, kanye nokwenza ama-lifti esakhiwo sakho asebenze kahle njengoba kufanele. Isakhiwo ngasinye sesimanje sidinga isignali ethembekile kuwo wonke amakhona, kufaka phakathi lawo aqonde phezulu.
Uma ubhekene nendawo engasebenzi kahle ezikhulwini zesakhiwo sakho—kungakhathaliseki ukuthi ungumphathi wezindlu, umnikazi webhizinisi, noma umninikhaya ohlala endlini encane—akudingeki ukuthi ubekezelele lokho.Chofoza lapha xhumana nathingezansi ngesimo sakho: zingaki izilifti onazo? Iyiphi inkinga enkulu obhekene nayo (ukushaya izingcingo, akukho siginali nhlobo, idatha ehamba kancane)? Ngizokwabelana ngqo ngohlobo lwe-booster oludingayo, futhi ngichaze ukuthi ungagwema kanjani amaphutha enziwa yiwo wonke umuntu. Azikho iziphakamiso zokuthengisa, iseluleko esiqotho nje esivela kothile olungise le nkinga yezakhiwo eziningi.
