Umthelela we-5G empilweni
Ubuchwepheshe be-5G, obumele isizukulwane sesihlanu samanethiwekhi angenantambo, buthembisa ukuguqula indlela esixhumana ngayo, esisebenza ngayo, futhi esiphila ngayo impilo yethu yansuku zonke. Njengoba ijubane ledatha liphezulu kanye nokubambezeleka okuphansi kunezizukulwane zangaphambilini, ukuthunyelwa kwe-5G emhlabeni wonke kulindeleke ukuthi kulethe izinzuzo eziningi emikhakheni esukela kwezempilo kuya kwezokuthutha. Kodwa-ke, kanye nalezi zinzuzo ezingaba khona, kuvela ukukhathazeka mayelana nomthelela we-5G empilweni yabantu. Lesi sihloko sizohlola umthelela we-5G empilweni ngokujulile ngokusekelwe ocwaningweni lwesayensi olutholakalayo kanye nemibono eyahlukene emphakathini.
Kuyini i-5G?
I-5G ubuchwepheshe benethiwekhi engenantambo besizukulwane esilandelayo obunikeza isivinini esikhulu kakhulu sokulanda idatha, ukubambezeleka okuphansi, kanye nomthamo omkhulu wenethiwekhi uma kuqhathaniswa nobuchwepheshe be-4G. Lezi sivinini esiphezulu zisekela izinhlelo zokusebenza ezahlukahlukene zobuchwepheshe obuphezulu njengezimoto ezizimele, i-Internet of Things (IoT), kanye ne-telemedicine.
I-5G isebenzisa ububanzi bemvamisa ephezulu, okuhlanganisa ama-millimeter wave (mmWave) bands asukela ku-24 GHz kuya ku-100 GHz kanye nama-frequency angaphansi kwe-6 GHz, ukuze kufezwe amazinga aphezulu edatha kanye nezikhathi zokuphendula ezisheshayo. Lokhu kuvumela inethiwekhi ukuthi iphathe amadivayisi amaningi ngesikhathi esisodwa futhi isekele ukuxhumana okuzinzile nokusheshayo.
Amagagasi kagesi kanye nempilo
Ngaphambi kokuba siqonde umthelela we-5G empilweni, kubalulekile ukuqonda okuncane ngamagagasi kagesi kanye nendlela asebenza ngayo. Amagagasi kagesi awuhlobo lokukhanya ngaphakathi kwe-electromagnetic spectrum, equkethe izinhlobo ezahlukene zamagagasi anamaza okukhanya ahlukahlukene kanye namaza. Izibonelo zalolu hlobo lokukhanya zifaka phakathi amagagasi omsakazo, ama-microwave, ama-infrared, ukukhanya okubonakalayo, ama-ultraviolet, ama-X-ray, kanye nemisebe ye-gamma.
Zombili i-4G ne-5G zisebenzisa amaza kagesi ukudlulisa idatha. Kodwa-ke, i-5G isebenzisa amaza aphezulu, ebangeni lamagagasi angamamilimitha. Lawa magagasi mafushane futhi abuthakathaka, adinga imibhoshongo noma ama-transmitter amaningi ukuqinisekisa ukumbozwa okwanele.
Ukukhathazeka Ngezempilo
Enye yezinto ezikhathazayo kakhulu mayelana nobuchwepheshe be-5G ukuthi bungaba nomthelela ongakanani empilweni yabantu. Ososayensi nabacwaningi bafunda izici eziningana zalolu daba:
1. Imisebe Engakhiphi I-Ionizing:
Imisebe esetshenziswa yi-5G, njengobuchwepheshe bangaphambilini, imisebe engakhiqizi i-ionizing. Lokhu kusho ukuthi ayinawo amandla anele okwenza ama-athomu noma ama-molecule abe yi-ionizing futhi ayikwazi ukuphula izibopho zamakhemikhali emzimbeni womuntu. Imisebe engakhizi ibhekwa njengengeyona ingozi kangako kunemisebe ekhiqizing i-ionizing njenge-X-ray noma imisebe ye-gamma, eyaziwa ngokulimaza i-DNA futhi ibangele umdlavuza.
2. Ukushisa:
Omunye umphumela ongaba khona wokuvezwa kwamagagasi e-millimeter ukushisa kakhulu kwezicubu zomzimba. Kodwa-ke, izifundo zikhombisile ukuthi amandla avela kumaza asetshenziswa yi-5G awanamandla ngokwanele ukubangela ukwanda okukhulu kokushisa kwezicubu zomuntu. Ukuchayeka kula magagasi ngokuvamile kubangela ukwanda okuncane kakhulu kokushisa kwesikhumba, okunganele ukubangela imiphumela emibi empilweni.
3. Ucwaningo Lwesayensi:
Kuze kube manje, izifundo eziningi ezenziwe ngemisebe engeyona i-ionizing evela kumadivayisi angenantambo (kufaka phakathi i-5G) azikabonisi ubufakazi obuqinile bemiphumela emibi empilweni. I-World Health Organization (WHO) kanye ne-International Commission on Protection from Non-Ionizing Radiation (ICNIRP) bamise imikhawulo yokuchayeka ebhekwa njengephephile emphakathini jikelele. Amadivayisi namanethiwekhi e-5G aklanyelwe ukuhlala ngaphakathi kwale mikhawulo.
4. Imiphumela Yesikhathi Eside:
Nakuba kungekho bufakazi obanele bokuphetha ngokuthi i-5G inemiphumela emibi empilweni yabantu, imiphumela yesikhathi eside yokuchayeka okuqhubekayo ayaziwa. Izifundo eziningi zigxile ekuchayekeni kwesikhathi esifushane, ngakho-ke, kudingeka ucwaningo olwengeziwe ukuqinisekisa ukuthi ukuchayeka isikhathi eside akubeki ingozi empilweni.
Imibono Yomphakathi Nokwethuka
Naphezu kobufakazi besayensi obutholakalayo, abantu abaningi basakhathazekile ngezingozi zezempilo ezingaba khona ze-5G. Ukwanda kolwazi olungalungile ezinkundleni zokuxhumana kuye kwabhebhethekisa imibono yokwesaba kanye nozungu, okwenza isimo saba sibi nakakhulu. Isibonelo, amanye amaqembu athi i-5G ingadala izifo ezahlukahlukene, okuhlanganisa umdlavuza kanye nezinkinga zesistimu yomzimba, yize lezi zimangalo zingasekelwa ubufakazi obuqinile besayensi.
Izinzuzo ze-5G zezeMpilo
Nakuba ukukhathazeka ngemiphumela emibi ye-5G empilweni kuye kwaphakanyiswa kabanzi, lobu buchwepheshe bunamandla amakhulu okuzuzisa umkhakha wezempilo. Ezinye izinzuzo ezibalulekile zifaka:
1. Imithi yokuxhumana:
I-5G ivumela ukuxhumana ngevidiyo okuseqophelweni eliphezulu, okubambezeleka kancane, okubalulekile ekusetshenzisweni kwezokwelapha ngocingo. Lokhu kuvumela ukuxilongwa nokuxoxisana okukude ngesikhathi sangempela, okungathuthukisa ukufinyelela ekunakekelweni kwezempilo ezindaweni ezikude.
2. Ukuhlinzwa Kwerobhothi:
Ijubane kanye nokuzinza kwamanethiwekhi e-5G kuvumela ukulawulwa kwerobhothi okude okunembe kakhulu. Lokhu kuvula ithuba lezinqubo zokuhlinzwa ezenziwa odokotela ezindaweni ezahlukene zezwe.
3. I-IoT Yezokwelapha:
Amanethiwekhi e-5G asekela amadivayisi amaningi e-IoT yezokwelapha angaqapha izimo zeziguli ngesikhathi sangempela. Lokhu kungathuthukisa ukuqapha impilo kanye nokutholakala kusenesikhathi kwezimo zezokwelapha ezidinga ukunakekelwa okusheshayo.
Isiphetho
Ubuchwepheshe be-5G buletha isithembiso soguquko lwedijithali olunezinzuzo ezingakaze zibonwe. Kodwa-ke, ukukhathazeka ngemiphumela yezempilo yalobu buchwepheshe kudinga ukunakwa okukhulu. Ngokusekelwe ocwaningweni lwesayensi olukhona, abukho ubufakazi obuqinile bemiphumela emibi yezempilo evela emisebeni engeyona i-ionizing esetshenziswa ku-5G. Kodwa-ke, kudingeka ucwaningo olwengeziwe ukuze kuqondwe imiphumela yesikhathi eside yalokhu kuvezwa kwemisebe.
Okubaluleke kakhulu, izinzuzo ezingaba khona ze-5G emkhakheni wezokunakekelwa kwempilo, njengokwelapha ngocingo kanye nokuhlinzwa kwerobhothi, zingabhekana nezinye zezinselele zezempilo zanamuhla. Ngakho-ke, indlela elinganiselayo ecabangela izingozi nezinzuzo ezingaba khona, kanye nolwazi olunembile nolusekelwe ebufakazini, iyadingeka ukufundisa umphakathi ngalobu buchwepheshe. Ngale ndlela, singasebenzisa amandla aphelele e-5G ngaphandle kokubeka impilo nokuphepha engcupheni.
