Kev sib ntaus sib tua rau 5G thev naus laus zis txoj hauv kev yog qhov tseem ceeb ntawm kev sib ntaus sib tua rau ntau zaus.Tam sim no, lub ntiaj teb no siv ob lub zaus sib txawv los siv 5G tes hauj lwm, qhov zaus band ntawm 30-300GHz hu ua millimeter yoj;lwm qhov yog hu ua Sub-6, uas yog concentrated nyob rau hauv 3GHz-4GHz zaus band.
Raws li cov yam ntxwv ntawm lub cev ntawm cov xov tooj cua tsis, qhov luv wavelength thiab nqaim beam yam ntxwv ntawm millimeter nthwv dej ua rau lub teeb liab daws teeb meem, kev ruaj ntseg kis tau tus mob, thiab kev sib kis ceev kom zoo dua, tab sis qhov kev sib kis tau zoo heev.
Raws li Google qhov kev ntsuam xyuas 5G rau tib qhov ntau thiab tib lub chaw nres tsheb, 5G network siv nrog millimeter nthwv dej tuaj yeem npog 11.6% ntawm cov pejxeem ntawm tus nqi ntawm 100Mbps, thiab 3.9% ntawm tus nqi ntawm 1Gbps.6-band 5G network, 100Mbps tus nqi network tuaj yeem npog 57.4% ntawm cov pejxeem, thiab 1Gbps tus nqi tuaj yeem them 21.2% ntawm cov pejxeem.
Nws tuaj yeem pom tias qhov kev pab them nqi ntawm 5G tes hauj lwm ua haujlwm hauv Sub-6 yog ntau dua 5 npaug ntawm millimeter nthwv dej.Tsis tas li ntawd, kev tsim kho ntawm millimeter nthwv dej hauv paus chaw nres tsheb yuav tsum muaj txog 13 lab kev teeb tsa ntawm cov khoom siv hluav taws xob, uas yuav raug nqi $ 400 billion, thiaj li ua kom 72% kev pab them nqi ntawm 100 Mbps ib thib ob hauv 28GHz band thiab txog 55 ib thib ob ntawm 1Gbps.% kev pab them nqi.Lub Sub-6 tsuas yog yuav tsum tau teeb tsa 5G hauv paus chaw nres tsheb ntawm qhov chaw nres tsheb 4G hauv paus, uas txuag tau nyiaj ntau heev.
Los ntawm kev pab them nqi rau kev siv lag luam, Sub-6 yog qhov zoo tshaj rau mmWave hauv lub sijhawm luv.
Tab sis yog vim li cas yog tias cov peev txheej spectrum muaj ntau, cov neeg nqa khoom bandwidth tuaj yeem ncav cuag 400MHz / 800MHz, thiab tus nqi xa xov wireless tuaj yeem ncav cuag ntau dua 10Gbps;qhov thib ob yog qhov nqaim millimeter-yoj kab teeb, kev taw qhia zoo, thiab kev daws teeb meem loj heev;qhov thib peb yog cov millimeter-yoj Cheebtsam Piv nrog Sub-6GHz cov cuab yeej, nws yooj yim dua rau miniaturize.Plaub, lub sijhawm subcarrier yog qhov loj, thiab tib lub sijhawm SLOT (120KHz) yog 1/4 ntawm qhov tsawg zaus Sub-6GHz (30KHz), thiab huab cua cuam tshuam qeeb.Hauv kev siv network ntiag tug, qhov zoo ntawm millimeter nthwv dej yuav luag crushing Sub-6.
Tam sim no, lub tsheb-hauv av kev sib txuas lus ntiag tug network tau siv los ntawm millimeter-yoj kev sib txuas lus hauv kev tsheb ciav hlau kev lag luam tuaj yeem ua tiav qhov kev sib kis ntawm 2.5Gbps nyob rau hauv kev kub ceev dynamic, thiab kev ncua sij hawm tuaj yeem ncav cuag 0.2ms, uas muaj tus nqi siab heev. ntawm private network promotion.
Rau cov tes hauj lwm ntiag tug, cov xwm txheej xws li kev tsheb ciav hlau thauj mus los thiab kev saib xyuas pej xeem kev nyab xeeb tuaj yeem muab kev ua si tag nrho rau cov txiaj ntsig ntawm millimeter nthwv dej kom ua tiav qhov tseeb 5G ceev.
