Ezibhedlela, umzuzwana ngamunye uyabaluleka—kungakhathaliseki ukuthi udokotela ohlela ukuhlinzwa okuphuthumayo, umndeni wesiguli obhalisa, noma isivakashi esikhokhela indawo yokupaka. Kodwa kuthiwani uma lezo zikhathi ezibucayi ziphazanyiswa isignali yeseli engabonakali? Yileyo kanye inkinga isibhedlela esikhulu eHunan, eShayina, esibhekane nayo: izindawo zokupaka ezingaphansi komhlaba, izitezi 1-4 zesakhiwo sabo esikhulu, kanye nazo zonke izilifti eziyi-10 zaziyizindawo ezifile ngokuphelele. Esikhungweni esiphatha amakhulu eziguli nsuku zonke, lokhu kwakungeyona nje inkinga—kwakuyingozi empilweni. Basithinta eLintratek, futhi ngemva kwezinsuku eziyi-7 zomsebenzi onzima, saguqula lezo zimbobo ezimnyama zesignali zaba ukumbozwa okuthembekile. Ake sibheke ukuthi sikwenze kanjani, akukho nkulumo yobuchwepheshe—izinselele zangempela nezixazululo zangempela.
Izibhedlela azifani nezakhiwo ezivamile; indawo yazo eyingqayizivele yenza ukumbozwa kwezimpawu kube yiphupho elibi. Igalaji yokupaka engaphansi komhlaba yayinophahla oluphakeme ngamamitha ayi-6 kanye nezindonga ezinkulu zekhonkrithi ezazivimba amasignali eseli angaphezu kwama-90%—cabanga ngakho njengesivikelo esikhulu esivimbela izimpawu zingangeni. Izitezi ezingezansi zesakhiwo esikhulu zazigcwele abantu nemishini yezokwelapha, okudala ukuphazamiseka okukhulu kwe-electromagnetic.
Futhi ama-lifti? Lawo ma-shaft aqondile adume ngokuwa kwesignali—cabanga ngomuntu osizayo ozama ukuvuselela isimo sesiguli phakathi nokuhamba, kodwa ucingo lwaphela. Ngaphezu kwakho konke lokho, besingeke sikwazi ukuphazamisa ukusebenza kwesibhedlela—akukho mathuluzi amakhulu ngesikhathi sokuvakasha, akukho ukuvimba imizila yezimo eziphuthumayo. Kwakuwukuhamba ngentambo eqinile phakathi kokuqeda umsebenzi nokugcina isibhedlela sisebenza kahle.
Sasazi ukuthi i-"single-fit" ifanelana-isikhuthazi sesignali sonkengeke kusebenze lapha. Ngakho-ke saklama ikhambi elenziwe ngokwezifiso: ingxube "yemishini ye-fiber optic eyenziwe ngokulingisa" kanye nemishini yethu ekhethekileizikhulisi zesignali ze-elevator(sibabiza ngokuthi“Izithuthukisi Zesignali Ze-Lifti”). Ezitezi ezimatasa zesakhiwo esikhulu neziphazamisayo kakhulu, sisebenzise ama-amplifiers anamandla aphezulu anqamula umsindo kagesi ngaphandle kokuphazamisa amadivayisi ezokwelapha—ukuphepha kuqala, njalo. Ukuze kube nokhonkolo obukhulu begaraji elingaphansi komhlaba, amadivayisi anamandla aphansi, aqondiswe ngokunemba angene ezindongeni ngaphandle kokuchitha isignali. Ama-lifti athole ama-booster awo azinikele, elilodwa ngomshaft, ukuqinisekisa ukudluliselwa kwesignali okungenamthungo njengoba izimoto zihamba zenyuka zehla—akusekho ukushaywa kwezingcingo lapho kubaluleke kakhulu. Siphinde sasebenzisa uhlelo olusatshalaliswa nge-fiber-optic ukuze siqede ukuphazamiseka ngokuphelele, ngakho-ke izingcingo eziphuthumayo kanye nezinkokhelo zeselula kuzoba lula.
Inqubo yokufaka yayimayelana nenhlonipho—yesibhedlela, iziguli, kanye nabasebenzi. Sasebenza ubusuku nempelasonto ukuze sigweme amahora amaningi, sasebenzisa amathuluzi athule, futhi sazulazula ezindaweni eziqinile nezimanzi egalaji lokupaka ukuze sibeke amamitha angu-200 amathreyi ekhebula angangeni manzi. Yonke i-antenna kanye ne-node kwakufakwe ama-bracket ngokwezifiso ukuze kugwenywe ama-sprinkler omlilo namapayipi, futhi sahlola kabili ukuxhumana ngakunye ukuqinisekisa ukuthi akukho ukuphazamiseka kwemishini ye-MRI, ama-heart monitor, kanye neminye imishini ebalulekile. Ngemva kwezinsuku eziyi-7 zasekuseni kakhulu kanye nasebusuku kakhulu, saphetha ngaphandle kwezikhalazo ezivela kubasebenzi noma ezigulini—impumelelo kulolo hlangothi yodwa yazwakala njengokunqoba.
Kodwa inzuzo yangempela yafika lapho sihlola isignali. Yonke indawo efile yayingasekho: igaraji lokupaka, izitezi ezimatasa, zonke izilifti eziyi-10—isignali yayigcwele yonke indawo. Ukuhlolwa kwesivinini kubonise amazinga e-4G/5G azinzile ngaphezu kwama-80 Mbps, okwanele izingcingo zevidiyo kanye nokudluliselwa kwamafayela amakhulu. Okubaluleke kakhulu, abasebenzi besibhedlela baqaphele umehluko omkhulu: izikhathi zokuthunyelwa eziphuthumayo zehle ngo-50%, futhi izinkokhelo zeselula egalaji lokupaka ziye zaphumelela ngo-100%. Udokotela oyedwa we-ER wasitshela ukuthi, “Manje sengingakwazi ukuhlala ngixhumekile kungakhathaliseki ukuthi ngikuphi esibhedlela—leyo mizuzu eyengeziwe egciniwe ingasho umehluko phakathi kokuphila nokufa.”
Lo msebenzi awuyona nje impumelelo yesikhathi esisodwa; uwuhlaka lwezinye izibhedlela, izindawo ezingaphansi komhlaba, nezindawo zomphakathi ezimatasa. Yingakho senza lokho esikwenzayo—hhayi nje ukulungisa isignali, kodwa futhi sisekela abantu abasindisa izimpilo.
