Dab tsi yog qhov txawv ntawm 4G thiab 5G thev naus laus zis

3G - tiam thib peb lub xov tooj txawb tau hloov pauv txoj kev peb sib txuas lus siv cov khoom siv txawb.4G tes hauj lwm txhim kho nrog cov ntaub ntawv zoo dua thiab cov neeg siv kev paub.5G yuav muaj peev xwm muab mobile broadband mus txog 10 gigabits ib ob ntawm qhov tsawg latency ntawm ob peb milliseconds.
Dab tsi yog qhov txawv ntawm 4G thiab 5G?
Ceev
Thaum los txog rau 5G, kev ceev yog thawj qhov uas txhua tus neeg txaus siab rau cov thev naus laus zis.LTE advanced technology muaj peev xwm ntawm cov ntaub ntawv tus nqi mus txog 1 GBPS ntawm 4G tes hauj lwm.5G thev naus laus zis yuav txhawb nqa cov ntaub ntawv nce txog 5 txog 10 GBPS ntawm cov khoom siv txawb thiab siab dua 20 GBPS thaum kuaj.

5G tuaj yeem txhawb nqa cov ntaub ntawv siv ntau yam xws li 4K HD multimedia streaming, augmented reality (AR) thiab virtual reality (VR).Ntxiv mus, nrog kev siv millimeter nthwv dej, cov ntaub ntawv tus nqi tuaj yeem nce siab tshaj 40 GBPS thiab txawm tias mus txog 100 GBPS hauv 5G network yav tom ntej.

millimeter nthwv dej muaj ntau qhov dav bandwidth piv rau qis bandwidth zaus bands siv hauv 4G technologies.Nrog bandwidth siab dua, cov ntaub ntawv ntau dua tuaj yeem ua tiav.
Latency
Latency yog lo lus siv hauv network technology los ntsuas qhov qeeb ntawm cov teeb liab pob ntawv ncav cuag los ntawm ib qho mus rau lwm qhov.Hauv cov xov tooj ntawm tes, nws tuaj yeem piav qhia raws li lub sijhawm coj los ntawm xov tooj cua teeb liab taug kev los ntawm lub hauv paus chaw nres tsheb mus rau lub xov tooj ntawm tes (UE) thiab rov ua dua.

Latency ntawm 4G network yog nyob rau hauv thaj tsam ntawm 200 txog 100 milliseconds.Thaum lub sij hawm 5G xeem, engineers tau ua tiav thiab ua kom pom qhov qis dua latency ntawm 1 txog 3 milliseconds.Tsawg latency yog qhov tseem ceeb heev hauv ntau lub hom phiaj tseem ceeb hauv kev siv thiab yog li 5G thev naus laus zis yog qhov tsim nyog rau cov ntawv thov qis qis.
Piv txwv li: tsheb tsav tus kheej, kev phais tej thaj chaw deb, kev ua haujlwm drone thiab lwm yam ...
Advanced Technology

Txhawm rau kom ua tiav cov kev pabcuam nrawm nrawm thiab qis qis, 5G yuav tsum siv cov lus sib txuas siab tshaj plaws xws li millimeter nthwv dej, MIMO, beamforming, ntaus ntawv mus rau kev sib txuas lus thiab tag nrho duplex hom.
Wi-Fi offloading kuj tseem yog lwm txoj hauv kev pom zoo hauv 5G txhawm rau ua kom cov ntaub ntawv ua tau zoo thiab txo cov khoom thauj ntawm cov chaw nres tsheb.Cov khoom siv txawb tuaj yeem txuas mus rau lub wireless LAN thiab ua txhua yam haujlwm (suab thiab cov ntaub ntawv) es tsis txhob txuas rau cov chaw nres tsheb hauv paus.
4G thiab LTE cov thev naus laus zis siv cov txheej txheem hloov kho xws li Quadrature Amplitude Modulation (QAM) thiab Quadrature Phase-Shift Keying (QPSK).Txhawm rau kov yeej qee qhov kev txwv hauv 4G cov qauv kev hloov pauv, lub xeev siab dua Amplitude Phase-Shift Keying txheej txheem yog ib qho kev xav rau 5G thev naus laus zis.
Network architecture
Nyob rau tiam dhau los ntawm cov xov tooj ntawm tes, Xov tooj cua Access Networks nyob ze rau lub hauv paus chaw nres tsheb.Traditional RANs yog qhov nyuaj, yuav tsum tau them nqi tsim kho, kev saib xyuas ib ntus thiab kev ua haujlwm tsawg.

5G thev naus laus zis yuav siv Cloud Radio Access Network (C-RAN) kom ua tau zoo dua.Cov neeg ua haujlwm hauv lub network tuaj yeem muab kev siv internet ceev ceev los ntawm lub hauv paus hauv huab raws li xov tooj cua nkag mus rau hauv lub network.
Internet ntawm Yam
Internet of Things yog lwm lub ntsiab lus loj uas feem ntau tham nrog 5G thev naus laus zis.5G yuav txuas ntau lab ntawm cov khoom siv thiab cov cuab yeej ntse rau hauv internet.Tsis zoo li 4G thev naus laus zis, 5G network yuav muaj peev xwm tuav cov ntaub ntawv loj los ntawm ntau daim ntawv thov xws li tsev ntse, muaj IoT, kev kho mob ntse, lub nroog ntse thiab lwm yam ...

Lwm daim ntawv thov loj ntawm 5G yog tshuab rau tshuab hom kev sib txuas lus.Autonomous tsheb yuav tswj txoj kev yav tom ntej nrog kev pab los ntawm cov kev pabcuam qis qis 5G.
Narrow Band - Internet of Things (NB - IoT) daim ntawv thov xws li teeb pom kev zoo, ntsuas ntsuas ntse, thiab cov kev daws teeb meem ntse, huab cua daim ntawv qhia yuav raug xa mus siv 5G network.
Ultra Reliable daws teeb meem
Piv nrog rau 4G, yav tom ntej 5G cov cuab yeej yuav muab kev sib txuas ib txwm, txhim khu kev ntseeg siab thiab muaj txiaj ntsig zoo.Qualcomm tsis ntev los no tau nthuav tawm lawv 5G modem rau cov cuab yeej ntse thiab cov khoos phis tawj tus kheej yav tom ntej.

5G yuav tuaj yeem tswj hwm cov ntaub ntawv loj los ntawm ntau lab ntawm cov khoom siv thiab lub network tuaj yeem hloov kho tau.4G thiab LTE tes hauj lwm tam sim no muaj kev txwv ntawm cov ntaub ntawv ntim, ceev, latency thiab network scalability.5G thev naus laus zis yuav tuaj yeem daws cov teeb meem no thiab muab cov kev daws teeb meem zoo rau cov neeg muab kev pabcuam thiab cov neeg siv kawg.
