Qhov txawv ntawm 4G thiab 5G thev naus laus zis yog dab tsi?

3G - lub network mobile tiam thib peb tau hloov pauv txoj kev uas peb sib txuas lus siv cov khoom siv mobile. 4G networks tau txhim kho nrog cov ntaub ntawv zoo dua thiab kev paub ntawm tus neeg siv. 5G yuav muaj peev xwm muab mobile broadband txog li 10 gigabits ib ob ntawm qhov latency qis ntawm ob peb milliseconds.
Qhov txawv tseem ceeb ntawm 4G thiab 5G yog dab tsi?
Ceev
Thaum los txog rau 5G, qhov ceev yog thawj qhov uas txhua tus neeg zoo siab txog cov thev naus laus zis. Cov thev naus laus zis LTE siab heev muaj peev xwm ua tau cov ntaub ntawv ceev txog li 1 GBPS ntawm 4G tes hauj lwm. Cov thev naus laus zis 5G yuav txhawb nqa cov ntaub ntawv ceev txog li 5 txog 10 GBPS ntawm cov khoom siv mobile thiab siab dua 20 GBPS thaum lub sijhawm sim.

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

Cov nthwv dej millimeter muaj bandwidth dav dua piv rau cov zaus bandwidth qis dua uas siv hauv 4G thev naus laus zis. Yog tias muaj bandwidth siab dua, qhov nrawm ntawm cov ntaub ntawv tuaj yeem ua tiav siab dua.
Kev ncua sijhawm
Latency yog lo lus siv hauv kev siv tshuab network los ntsuas qhov qeeb ntawm cov pob teeb liab mus txog ntawm ib lub node mus rau lwm qhov. Hauv cov tes hauj lwm mobile, nws tuaj yeem piav qhia tias yog lub sijhawm siv los ntawm cov teeb liab xov tooj cua mus ncig los ntawm chaw nres tsheb mus rau cov khoom siv mobile (UE) thiab rov qab los.

Qhov latency ntawm 4G network yog nyob rau hauv qhov ntau ntawm 200 txog 100 milliseconds. Thaum lub sijhawm sim 5G, cov engineers tau ua tiav thiab ua pov thawj qhov latency qis dua ntawm 1 txog 3 milliseconds. Qhov latency qis yog qhov tseem ceeb heev hauv ntau daim ntawv thov tseem ceeb thiab yog li 5G thev naus laus zis yog qhov tsim nyog rau cov ntawv thov latency qis.
Piv txwv li: tsheb tsav tus kheej, phais mob deb, kev siv drone thiab lwm yam...
Kev Siv Tshuab Siab Tshaj Plaws

Yuav kom ua tiav cov kev pabcuam ultra-fast thiab qis latency, 5G yuav tsum siv cov lus siv hauv network siab heev xws li millimeter waves, MIMO, beamforming, device to device communication thiab full duplex mode.
Kev rho tawm Wi-Fi kuj yog lwm txoj hauv kev pom zoo hauv 5G los ua kom cov ntaub ntawv siv tau zoo dua thiab txo qhov hnyav ntawm cov chaw nres tsheb. Cov khoom siv txawb tuaj yeem txuas rau LAN wireless uas muaj thiab ua txhua yam haujlwm (suab thiab ntaub ntawv) es tsis txhob txuas rau cov chaw nres tsheb.
Cov thev naus laus zis siab heev ntawm 4G thiab LTE siv cov txheej txheem modulation xws li Quadrature Amplitude Modulation (QAM) thiab Quadrature Phase-Shift Keying (QPSK). Yuav kom kov yeej qee qhov kev txwv hauv cov phiaj xwm modulation 4G, cov txheej txheem Amplitude Phase-Shift Keying siab dua yog ib qho ntawm kev xav txog rau thev naus laus zis 5G.
Kev tsim qauv network
Hauv cov tiam neeg ua ntej ntawm cov tes hauj lwm mobile, Radio Access Networks nyob ze rau lub hauv paus chaw nres tsheb. RANs ib txwm muaj ntau yam nyuaj, xav tau cov khoom siv kim heev, kev saib xyuas tsis tu ncua thiab kev ua haujlwm tsawg.

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

Lwm qhov kev siv loj ntawm 5G yog kev sib txuas lus ntawm tshuab mus rau tshuab. Cov tsheb uas tsav tsis tau tus kheej yuav yog txoj kev yav tom ntej nrog kev pab los ntawm cov kev pabcuam 5G uas qeeb qeeb.
Cov ntawv thov Narrow Band - Internet of Things (NB - IoT) xws li lub teeb pom kev zoo ntse, cov ntsuas ntse, thiab cov kev daws teeb meem chaw nres tsheb ntse, daim ntawv qhia huab cua yuav raug xa mus siv 5G network.
Cov kev daws teeb meem txhim khu kev qha heev
Piv rau 4G, cov khoom siv 5G yav tom ntej yuav muab cov kev daws teeb meem uas txuas nrog tas li, txhim khu kev qha thiab ua haujlwm tau zoo heev. Qualcomm nyuam qhuav tshaj tawm lawv lub modem 5G rau cov khoom siv ntse thiab cov khoos phis tawj yav tom ntej.

5G yuav muaj peev xwm tswj tau cov ntaub ntawv loj heev los ntawm ntau txhiab lab lub cuab yeej thiab lub network tuaj yeem hloov kho tau. 4G thiab LTE networks tam sim no muaj kev txwv hauv cov ntaub ntawv ntim, ceev, latency thiab network scalability. 5G technologies yuav muaj peev xwm daws cov teeb meem no thiab muab cov kev daws teeb meem pheej yig rau cov neeg muab kev pabcuam thiab cov neeg siv kawg.
