Thawj Verizon C-Band Cov txiaj ntsig tshwm sim: Kev txhawb nqa, Tab sis FAA puas yuav tua nws?

Verizon's 5G network tuaj yeem ntes nrog T-Mobile sai heev hauv 46 lub nroog loj, tshwj tsis yog FAA thiab cov dav hlau kaw nws, raws li thawj qhov kev xeem tau los ntawm Verizon C-Band 5G tshiab.

Verizon tau caw ob peb tus neeg sau xov xwm thiab cov kws tshuaj ntsuam tawm mus rau Los Angeles siv sijhawm ib teev nrog C-Band ntawm LA Live kev lom zem koog tsev kawm ntawv. (Kuv raug caw, tab sis kuv ua tsis tau.)

Tom's Guide's Philip Michaels pom yuav ua li cas C-Band yuav txo qhov kev ntxhov siab ntawm Verizon's LTE network, siab kuv kuj pom thaum kuaj ntawm lub khw hnub so hauv Manhattan. Raws li nws, ib qho LTE nkaus xwb iPhone 11 Pro Max pom 34.9Mbps ntawm LTE Hauv qhov chaw uas Samsung Galaxy S21 Ultra tau txais 1Gbps ntawm C-Band.

Tab sis tau kawg, koj tuaj yeem tau txais cov nrawm nrog millimeter-yoj, ib yam nkaus; nws tsuas yog hais tias millimeter-yoj tsis npog ntau thaj chaw. CNet's David Lumb tau txais 458Mbps ntawm C-Band hauv elevator. millimeter-yoj tsis ua haujlwm zoo hauv tsev, tshwj tsis yog lub kav hlau txais xov nyob hauv chav nyob ze.

Tus kws tshuaj ntsuam Bill Ho hais tias nws pom qhov nrawm ntawm 649Mbps ib mais ntawm C-Band ntauwd, uas yog qhov sib txawv loj heev los ntawm millimeter-yoj kev ua haujlwm ceev ntawm 800 ko taw. Cov txiaj ntsig zoo li no zoo ib yam li kuv qhov kev sim ua ntej ntawm Verizon's 4G CBRS, uas yog nyob ntawm qhov sib xws.

Verizon tau cog lus tias yuav tshaj tawm C-Band thaum Lub Ib Hlis 5 thiab npog 100 lab tus neeg Asmeskas hauv 46 "ib feem kev lag luam" nrog C-Band thaum kawg lub Peb Hlis. Cov PEAs, uas qee zaum peb xa mus rau qhov tsis raug raws li thaj chaw metro, muaj ntau dua li thaj chaw metro. Ib qho rau New York suav nrog tag nrho lub xeev Connecticut, txawm li cas los xij, nyob deb nroog, thiab ib qho rau Miami suav nrog tag nrho lub quarter sab qab teb ntawm Florida ceg av qab teb, piv txwv li.

Qhov zoom no qhia qee qhov ntawm FCC's C-Band PEA daim ntawv qhia. Cov cheeb tsam uas muaj tus lej qis dua 51 tuaj yeem tau txais C-Band hauv 2022, tshwj tsis yog (hauv daim duab qhia no) #5, Washington DC, uas muaj kev siv tub rog ntau dhau ntawm cov spectrum. Lwm thaj chaw yuav tsum tau tos kom txog rau thaum xyoo 2024. Daim ntawv ceeb toom yuav ua li cas txhua cheeb tsam loj dua ib lub nroog, thiab feem ntau suav nrog cov xeev nyob sib ze.

AT&T tseem yuav siv C-Band rau xyoo tom ntej, hais tias nws yuav them 70-75 lab tus neeg Asmeskas nyob rau thaum xaus ntawm lub xyoo, tab sis nws tsis tau teem nws tus kheej kom ruaj khov raws li Verizon muaj.

C-Band tau txais kev txhawb nqa los ntawm ntau lub xov tooj uas tau tawm xyoo dhau los, suav nrog iPhone 12 thiab iPhone 13 series, Samsung Galaxy S21 thiab Pixel 5 thiab 6, tab sis tsis yog feem ntau cov xov tooj uas tawm ua ntej cov.

Kev pab them nqi tseem tuaj yeem dhau los txwv thiab kev tshaj tawm tseem tuaj yeem ncua sijhawm, txawm li cas los xij, vim tias kev lag luam huab cua kev sib ntaus sib tua tiv thaiv C-Band tsis ua tiav. Raws li tsab ntawv xov xwm tshiab ntawm Wall Street Journal, FAA tseem tuav txoj kab uas cov neeg nqa khoom yuav tsum tsis txhob tshaj tawm qhov tsis tau teev tseg ntawm lawv cov C-Band tes hauj lwm, lossis FAA yuav tshaj tawm cov cai. txwv tsis pub lub dav hlau tsaws nyob rau hauv huab cua phem. FAA thov tias C-Band 5G yuav cuam tshuam nrog lub dav hlau xov tooj cua altimeters, txawm hais tias nws lees tias European regulators tsis pom qhov tshwm sim. Cov thawj coj hauv dav hlau tau hais tias Chicago O'Hare, Atlanta thiab Detroit yuav nyob hauv cov tshav dav hlau cuam tshuam.

Peb mam li paub thaum ntxov xyoo tom ntej.
