Deciphering keeb kwm ntawm kev loj hlob thiab kev hloov ntawm Mobile Communication Technology Kev sib txuas lus yog dab tsi? (5)
5G: Muab faib ua ob pawg ntawm mobile Internet thiab Internet ntawm Yam, qhov ceev yuav ncav cuag 10 Gbps
5G, lub thib tsib-tiam mobile kev sib txuas lus thev naus laus zis, kuj yog qhov txuas ntxiv tom qab 4G. Tam sim no, cov kev xav tau thiab cov ntsuas kev qhia tseem ceeb (KPIs) ntawm 5G tau raug txiav txim siab. Lub ITU faib 5G daim ntawv thov scenarios ua ob pawg: mobile Internet thiab Internet ntawm Yam. Txhua lub teb chaws ntseeg hais tias ntxiv rau kev txhawb nqa kev txhim kho ntawm lub xov tooj ntawm tes Internet, 5G tseem yuav daws cov kev xav tau ntawm kev sib txuas lus wireless loj ntawm cov tshuab thiab txhawb kev loj hlob ntawm Is Taws Nem ntawm Tsheb, Muaj Is Taws Nem thiab lwm yam.
5G nthuav qhia cov yam ntxwv ntawm qis latency, muaj kev ntseeg siab, thiab siv hluav taws xob tsawg
Raws li qhov kev npaj tam sim no muaj kev txhawj xeeb, 5G txawv ntawm 4G, 3G, thiab 2G. Nws tsis yog ib qho kev siv wireless nkaus xwb, lossis ob peb lub wireless nkag tau tshiab, tab sis ntau yam kev siv wireless tshiab thiab cov thev naus laus zis uas twb muaj lawm. Muaj ib lub ntsiab lus dav dav rau kev daws teeb meem ntawm kev siv tshuab wireless (4G rov qab hloov pauv tshuab). 5G thov tau nthuav dav rau qhov chaw IoT.
Nws yuav tsum tau hais tias kev kub ceev yog qhov loj tshaj plaws ntawm 5G. Kev txhim kho tom ntej ntawm 4G tuaj yeem ncav cuag qhov siab tshaj plaws Internet ceev ntawm 1G, thaum 5G tuaj yeem ncav cuag qhov siab tshaj plaws ntawm 10G. Qhov no kuj txhais tau tias nyob rau hauv 5G network ib puag ncig, cov yeeb yaj kiab uas muaj cov ntsiab lus zoo tshaj plaws tuaj yeem rub tawm hauv 1 thib ob. Piv nrog rau 4G network, 5G network tsis tsuas yog muaj kev sib kis ntau dua, tab sis kuj nthuav tawm cov yam ntxwv ntawm qis latency, muaj kev ntseeg siab, thiab siv hluav taws xob tsawg thaum sib kis. Kev siv hluav taws xob tsawg tuaj yeem txhawb nqa IoT kev siv tau zoo dua.
Txawm hais tias tus qauv 5G tam sim no tseem nyob deb, xav txog qhov kev nkag mus rau lub davhlau ya nyob twg loj thiab cov ntaub ntawv yuav tsum tau coj los ntawm Is Taws Nem ntawm Tsheb thiab Is Taws Nem ntawm Yam yav tom ntej, nrog rau ntau yam kev paub txog kev txhim kho, qee qhov "yuav tsum tau nyuaj" txog 5G. tau dav paub ua ntej. Kev sib txuas lus wireless feem ntau yog hloov kho txhua 10 xyoo. 3G pib loj hlob thiab kev lag luam hauv xyoo 2000, thiab 4G pib loj hlob thiab kev lag luam hauv xyoo 2010. Tam sim no 5G tab tom kawm, thiab kev loj hlob hauv 2020 yuav tsum tau ua raws li txoj cai.
