Ibamba lenhloko ye-US National Oceanic and Atmospheric Administration (NOAA), uNeil Jacobs, uthe ukuphazamiseka kwama-smartphones e-5G kunganciphisa ukunemba kokubikezela kwesimo sezulu ngo-30%. Ngokombono wakhe, ithonya eliyingozi lamanethiwekhi e-5G lizobuya nge-meteorology emashumini eminyaka edlule. Ubalule ukuthi izibikezelo zesimo sezulu zazinemba engaphansi ngo-30% kunalokho esiyikho manje ngo-1980. UMnu Jacobs ukusho lokhu ngesikhathi ekhuluma kuCongress yaseMelika ezinsukwini ezimbalwa ezedlule.
Lezi zindaba kufanele zithinte izakhamuzi ezisezindaweni ezisogwini lwase-United States, njengoba zizoba nesikhathi esincane sezinsuku ezingu-2-3 sokulungiselela iziphepho ezizayo. I-NOAA ikholelwa ukuthi ukuphazamiseka okudalwe amanethiwekhi e-5G kungathinta ukunemba kwemizila yeziphepho.
Khumbula ukuthi i-Federal Communications Commission (FCC) yethule indali lapho ububanzi befrikhwensi obungu-24 GHz buzothengiswa buphele. Lokhu kwenzeke naphezu kwemibhikisho ye-NASA, NOAA kanye ne-US Meteorological Society. Kamuva, izigele ezimbalwa zacela i-FCC ukuthi ivimbele ukusetshenziswa kwebhendi yefrikhwensi engu-24 GHz kuze kube yilapho kwakhiwa uhlobo oluthile lwesixazululo senkinga.
Ingqikithi yenkinga iwukuthi ngesikhathi sokwakhiwa komhwamuko wamanzi, amasiginali abuthakathaka emvamisa ye-23,8 GHz athunyelwa emkhathini. Le mvamisa iseduze nebanga izinkampani zezokuxhumana ezihlose ukulisebenzisa lapho zisebenzisa amanethiwekhi okuxhumana esizukulwane sesihlanu (5G). Lezi zibonakaliso zilandelwa amasathelayithi ezulu, anikeza idatha esetshenziselwa ukubikezela iziphepho nezinye izenzakalo zesimo sezulu. Izazi zezulu zikholelwa ukuthi ama-opharetha e-telecom angasebenzisa isignali enamandla kancane eziteshini eziyisisekelo, okuzonciphisa izinga lokuphazamiseka okuphazamisa ukusebenza kwezinzwa ezibucayi.
Okunye okukhathaza izazi zezulu ukuthi i-FCC ihlose ukuqhubeka nokudayisa amaza ezinkampanini zokuxhumana. Sikhuluma ngamabhendi aseduze nalawo asetshenziswa manje ukuthola imvula (36–37 GHz), ukuqapha izinga lokushisa (50,2–50,4 GHz), kanye nokutholwa kwamafu (80–90 GHz). Njengamanje, iziphathimandla zaseMelika zidingida lolu daba nezinye izifundazwe, zizama ukuthola isisombululo kule nkinga. Kulindeleke ukuthi isinqumo ngalolu daba sikhishwe ngoMfumfu nonyaka, lapho kuzoba neNgqungquthela Yomhlaba Yezokuxhumana Ngomsakazo.
Kuyaphawuleka ukuthi indali ephethwe yi-FCC, esivele ilethe inzuzo elinganiselwa ku-$2 billion ekuthengisweni kwamafrikhwensi okwakha amanethiwekhi e-5G, isaqhubeka.
