Key Takeaways
- FAA tau tshaj tawm cov lus qhia txog kev txhawj xeeb tias 5G cov kev pabcuam los ntawm AT&T thiab Verizon tuaj yeem cuam tshuam nrog xov tooj cua altimeters hauv dav hlau.
- Txoj kev sib txawv yuav ua rau cov nyiaj poob qis hauv kev ncua thiab kev sib txawv, qhia txog kev lag luam dav hlau.
- Kev lag luam hauv xov tooj ntseeg tias FAA qhov kev txhawj xeeb tsis muaj tseeb.
Yog Tsoom Fwv Teb Chaws Kev Tswj Xyuas Kev Nyab Xeeb (FAA) muaj nws txoj hauv kev, koj yuav tsis tuaj yeem siv 5G cov kev pabcuam los ntawm AT&T thiab Verizon txij Lub Ib Hlis 2022, raws li tau npaj tseg.
Hu rau qhov kev xa tawm qeeb, FAA thawj zaug tau sib cav tias 5G C-band antennas tuaj yeem cuam tshuam nrog cov khoom siv dav hlau tseem ceeb. Tom qab ntawd nws tau mus tom ntej thiab tau tshaj tawm ob peb nqe lus qhia txog kev tsim nyog (AD) xaj kom cov dav hlau hloov pauv lub davhlau raws li qee qhov xwm txheej, uas cov neeg sab hauv kev lag luam hais tias tuaj yeem raug nqi ntau lab daus las.
"Yog tias AD tau siv rau hauv qhov tsis txaus rau Airlines rau Asmeskas cov tswv cuab 2019 kev ua haujlwm, kwv yees li 345,000 tus neeg caij dav hlau, 32 lab tus neeg caij tsheb, thiab 5,400 lub dav hlau thauj khoom yuav raug cuam tshuam rau hauv daim ntawv ntawm kev ya davhlau qeeb, Kev hloov pauv, lossis kev tshem tawm, " xaus qhov Kev Tshawb Fawb Txog Kev Nyuaj Siab ntawm FAA's 5G Airworthiness Directive los ntawm Airlines rau Asmeskas, koom nrog Lifewire.
Txoj Cai
Lub Kaum Ib Hlis 2021, AT&T thiab Verizon tau pom zoo ncua kev lag luam tawm ntawm C-band 5G wireless kev pabcuam mus txog Lub Ib Hlis 5, 2022, tom qab FAA tau tsa kev txhawj xeeb txog kev nyab xeeb txog nws qhov cuam tshuam rau cov khoom siv dav hlau tseem ceeb.
Raws li hnub tshiab ntawm kev tshaj tawm mus txog, FAA tau tshaj tawm ADs hu rau kev hloov kho ntawm cov ntawv qhia dav hlau txwv tsis pub qee qhov kev ua haujlwm dav hlau nyob ntawm kev siv xov tooj cua altimeters thaum muaj 5G C-band wireless broadband signals.
Txawm hais tias tsis muaj pov thawj ntseeg tau tias muaj kev pheej hmoo rau kev nyab xeeb kev dav hlau, Asmeskas cov chaw muab kev pabcuam wireless tau yeem tso rau hauv lub ntiaj teb cov txheej txheem kev tiv thaiv ib ntus.
Nyob rau hauv nqe lus rau Lifewire, Carter Yang, Tus Thawj Saib Xyuas Kev Lag Luam, Kev Lag Luam Kev Lag Luam rau Kev Lag Luam rau Tebchaws Asmeskas, tau hais tias ADs los ntawm FAA txheeb xyuas kev txhawj xeeb txog kev nyab xeeb uas yuav cuam tshuam "kev cuam tshuam" rau lub teb chaws airspace system thiab pej xeem.
Cov ADs tseem ceeb hais kom cov dav hlau tsis txhob cia siab rau lub xov tooj cua altimeters thaum mus txog lub tshav dav hlau ze ntawm 5G C-band kav hlau txais xov thiab hloov pauv mus rau lwm lub tshav dav hlau. Cov tuam txhab lag luam rau Asmeskas ntseeg tias lub luag haujlwm los daws qhov teeb meem tsis txaus ntseeg nrog cov tuam txhab xov tooj.
"Qhov tsis muaj kev txo qis loj ntawm ib feem ntawm 5G cov tuam txhab kev sib txuas lus los daws cov teeb meem cuam tshuam yuav cuam tshuam loj heev thiab ua rau muaj kev puas tsuaj rau kev lag luam nyob rau lub sijhawm thaum cov khoom lag luam tau nthuav dav zuj zus," nyeem cov Kev Tshawb Fawb Txog Kev Nyuaj Siab rau Asmeskas.
False Flag
Michael Marcus, tus kws tshaj lij ntawm hluav taws xob thiab khoos phis tawj engineering ntawm Northeastern University thiab tus kws tshaj lij ntawm wireless technology thiab spectrum txoj cai, hais rau Lifewire hauv email tias qee lub radar altimeters yeej raug rau 5G hauv cov kab nyob ze. Txawm li cas los xij, nws tsis txaus siab los ntawm FAA cov lus teb.
"Vim [tus] FAA cia qhov teeb meem no tsis zoo, lawv nyuam qhuav pib sau cov ntaub ntawv ntawm cov qauv twg thiab lawv muaj pes tsawg," nws hais.
Raws li yav dhau los Associate Chief of the Federal Communication Commission (FCC) 's Office of Engineering thiab Technology, Marcus tau pom cov xwm txheej zoo li no yav dhau los.
Hu rau cov teeb meem uas nyob ib sab "zoo ib yam," Marcus tau taw qhia txog kev txhawj xeeb peb-xyoo-laus ntawm kev siv FM tshaj tawm qis dua 108 MHz thiab lub dav hlau Cov Cuab Yeej Cuab Yeej (ILS) saum toj no zaus.
"Qhov teeb meem tiag tiag yog seb cov neeg nqa khoom ntawm tes yuav muaj lub nra loj hauv kev daws qhov teeb meem no, lossis cov tswv ntawm qee cov qauv ntawm radar altimeters hauv dav hlau uas tsis ua raws li cov qauv kev tiv thaiv kev cuam tshuam tsim nyog," said Marcus.
Nruab nrab
Meanwhile, Airlines rau Amelikas Yang tau hais tias cov pab pawg tseem yaum kom FCC thiab FAA ua haujlwm ua ke ntawm cov kev daws teeb meem uas yuav ua rau kev nthuav tawm ntawm 5G C-band technology "thaum saib xyuas kev nyab xeeb thiab tsis txhob muaj kev cuam tshuam rau kev lag luam. aviation system."
Ib qho kev pom zoo sib xws tau qhia los ntawm Meredith Attwell Baker, Thawj Tswj Hwm thiab CEO ntawm CTIA, lub koom haum kev lag luam sawv cev rau kev lag luam kev sib txuas lus wireless hauv Asmeskas, thiab yav dhau los tus tswv cuab ntawm FCC. Hauv tsab ntawv tshaj tawm rau Lifewire, Baker tau hais tias nws tuaj yeem muaj kev nyab xeeb kev ya davhlau thiab kev pabcuam 5G muaj zog thiab ntseeg tau.
"Txawm hais tias tsis muaj pov thawj ntseeg tau hais tias muaj kev pheej hmoo rau kev nyab xeeb aviation, US cov chaw muab kev pabcuam wireless tau yeem tso rau hauv lub ntiaj teb cov txheej txheem kev tiv thaiv ib ntus. 40 lub teb chaws nyab xeeb siv 5G hauv C-Band thaum Lub Ib Hlis, "paub Baker.
Txhua yam nyob hauv limbo tam sim no, thiab nws tsis paub meej tias 5G C-band cov kev pabcuam yuav muaj pib txij Lub Ib Hlis 5, 2022, lossis yog tias qhov kev tshaj tawm yuav raug ncua ntxiv vim tias ob lub koomhaum tseemfwv qib siab sib tw rau ib qho- kev kho mob.
