5G yog tiam tom ntej ntawm kev kub ceev wireless internet. Nws tshaj 4G nyob rau hauv kev ceev los ntawm tsawg kawg yog ib qho ntawm 10, thiab tseem ceev tshaj qhov uas cov neeg feem coob tau txais los ntawm lawv cov wired broadband kev twb kev txuas hauv tsev.
Thaum qhov ntawd yuav zoo nkauj, nws tseem nyuaj rau kev nkag siab tias qhov no txhais tau li cas rau koj thaum koj siv koj lub xov tooj lossis rub tawm ib yam dab tsi hauv tsev hauv koj lub computer. 5G sai dua li cas thaum nws los txog rau cov haujlwm tsis tu ncua xws li rub tawm cov apps thiab streaming tsos?
Nws yooj yim los tham txog yuav ua li cas 5G tuaj yeem hloov lub ntiaj teb, xws li ua kom muaj kev paub txog VR thiab AR, kev hu xov tooj holographic, sib cuam tshuam lub nroog ntse, thiab lwm yam. Txawm li cas los xij, kom nkag siab tias nws ceev npaum li cas, cia peb saib qee qhov ntxiv sib txheeb, piv txwv hauv ntiaj teb tiag.
5G Ceev: Dab tsi Cov Qauv Hu Rau
Rau lub network kom suav tias yog 5G, nws yuav tsum ua raws li qee cov cai uas tau teev tseg los ntawm cov thawj coj zoo li 3GPP. Ib qho ntawm cov kev qhia tshwj xeeb yog ceev rau kev rub tawm thiab rub tawm.
Muaj qhov tsawg kawg nkaus rub tawm tus nqi thiab qhov tsawg kawg nkaus tus nqi xa tawm rau lub network hu ua 5G network, txhais tau tias txhua qhov chaw nres tsheb 5G yuav tsum txhawb nqa qhov nrawm tsawg kawg qhov nrawm no:
- 5G peak download ceev: 20 Gb / s (gigabits ib ob), lossis 20, 480 Mb / s (megabits ib ob)
- 5G peak upload ceev: 10 Gb / s (gigabits ib ob), lossis 10, 240 Mb / s (megabits ib ob)
Nco ntsoov tias ob pawg ntawm cov lej no zoo ib yam, lawv tsuas yog siv qhov sib txawv ntawm kev ntsuas. Nco ntsoov tias cov khoom tsis zoo ib yam li bytes (cov ntsuas saum toj no tau sau ua cov khoom).
Hloov Gigabits rau Megabytes thiab Gigabytes
Vim tias muaj yim me ntsis hauv txhua byte, txhawm rau hloov cov 5G nrawm rau hauv megabytes (MB) thiab gigabytes (GB), koj yuav tsum faib lawv los ntawm yim. Ntau qhov kev ntsuas nyob rau hauv cov chav no tsis yog megabits thiab gigabits, yog li nws tseem ceeb kom nkag siab ob qho tib si.
Ntawm no yog tib 5G nrawm, lub sijhawm no sau hauv bytes tsis yog cov khoom:
- 5G peak download ceev: 2.5 GB / s (gigabytes ib ob), lossis 2, 560 MB / s (megabytes ib ob)
- 5G peak upload ceev: 1.25 GB / s (gigabytes ib ob), lossis 1, 280 MB / s (megabytes ib ob)
Yam tsawg kawg latency Requirement
5G kuj tseem muaj qhov xav tau latency yam tsawg kawg nkaus. Latency yog hais txog qhov sib txawv ntawm lub sij hawm ntawm lub xov tooj ntawm tes xa cov ntaub ntawv thiab thaum lub hom phiaj ntaus ntawv (xws li koj lub xov tooj) tau txais cov ntaub ntawv.
5G xav tau qhov tsawg kawg nkaus latency ntawm tsuas yog 4 ms, piv txwv tias cov xwm txheej zoo tshaj plaws tau ntsib, tab sis tuaj yeem poob qis li 1 ms rau qee hom kev sib txuas lus, tshwj xeeb tshaj yog kev sib txuas lus ultra-txhim kho thiab qis-latency (URLLC).
Rau qhov sib piv, qhov latency ntawm 4G network yuav nyob ib puag ncig 50-100 ms, uas yog qhov tseeb ntau dua li ob zaug nrawm dua li cov laus 3G network.
Qhov tseeb 5G Network Ceev
Cov kev ntsuas tau teev saum toj no yog qhov kev xav ntawm 5G nrawm hauv cov xwm txheej zoo tshaj plaws uas tsis muaj latency lossis cuam tshuam, thiab tsuas yog tias koj lub cuab yeej tsuas yog siv 5G ntawm tes.
Txhua 5G xov tooj txhawb nqa, yam tsawg kawg, ib lab cov khoom siv rau txhua square km. Download thiab upload ceev tau muab faib sib npaug ntawm txhua lub cuab yeej ntawm tib lub xov tooj.
Hauv lwm lo lus, cov neeg siv mobile tej zaum yuav tsis muaj qhov siab tshaj plaws download / upload ceev. Txawm li cas los xij, nws tuaj yeem tau txais cov kev ceev no yog tias koj siv lub siab, ruaj ruaj wireless nkag (FWA) qhov system uas koj tsis tas yuav faib cov bandwidth nrog lwm tus neeg siv.
Piv txwv li, UK peb tus neeg siv xov tooj ntawm tes tau ua tiav qhov nrawm nrawm 2 Gb / s rub tawm ntawm qhov chaw nkag wireless (FWA) ib puag ncig, tab sis Peb xav kom cov neeg siv ib txwm rub tawm tsuas yog 80 txog 100 Mb / s.
Hais tias, 5G ceev npaum li cas, tiag tiag? Yog tias koj xav sau npe tam sim no, koj xav tau dab tsi hauv internet ceev?
yam uas cuam tshuam rau kev nrawm
Hmoov tsis zoo, cov lus teb tsis ncaj ncees. Qhov tseeb 5G ceev yog nyob ntawm tsis yog qhov chaw koj nyob thaum koj nkag mus rau hauv lub network, tab sis lwm yam xws li kho vajtse koj siv, qhov ceev ntawm lub network muaj peev xwm, muaj pes tsawg tus neeg siv sib koom 20+ Gb / s, thiab hom kev cuam tshuam dab tsi ntawm kev ua si ntawm koj thiab lub xov tooj xa 5G.
Nrog Verizon, piv txwv li, uas yog ib lub tuam txhab thawj zaug tso tawm 5G hauv Tebchaws Meskas, peb tuaj yeem pom tias Verizon 5G Cov neeg siv hauv tsev nrog FWA tuaj yeem tau txais qhov twg los ntawm 300 Mb / s txog 1 Gb / s. Tsis tsuas yog Verizon's 5G broadband kev pabcuam lav zoo li no, cov neeg siv qhia tib yam.
Kev twv nrawm nrawm
Tshaj li cov ntaub ntawv peb tuaj yeem sib sau hnub no nrog 5G tes hauj lwm nyob, yog cov kev xav tau los ntawm cov neeg nqa khoom. T-Mobile, piv txwv li, hais tias 450 Mb / s yog qhov nruab nrab ceev uas tus neeg siv tuaj yeem xav tau; qhov no yuav tsum mus siab li 4 Gb/s los ntawm 2024.
Qee lub tuam txhab tau ntsuas 5G nrawm dua. Nyiv NTT DOCOMO ua tiav ntau dua 25 Gb / s thaum lub sijhawm 5G sim nrog lub tsheb txav.
Hais tias, nws tseem ceeb heev kom nco ntsoov txhua yam ntawm kev ua si uas cuam tshuam ceev. Nyob hauv tsev muaj peev xwm qee zaum txo qis ntawm qhov ceev, thiab txav mus rau hauv lub tsheb lossis txawm tias taug kev hauv txoj kev tuaj yeem ua rau muaj kev nrawm nrawm.
Dab tsi 5G's Wireless Ceev txhais tau rau koj
Zoo li peb tau hais los saum toj no, tsis muaj cov piv txwv, nws tuaj yeem nyuaj rau pom qhov koj tuaj yeem ua ntawm 5G network vs 4G network, lossis lwm yam kev sib txuas qeeb dua.
Xav txog qhov no: Koj rub tawm cov yeeb yaj kiab uas loj 3 GB, siv 5G, 4G, 4G LTE, thiab 3G tes hauj lwm. Ntawm no yog nws yuav siv sijhawm ntev npaum li cas los rub tawm cov yeeb yaj kiab ntawm ntau hom xov tooj ntawm tes (siv qhov nrawm tiag tiag, tsis yog qhov nrawm):
- 3G: 1 teev, 8 feeb1
- 4G: 40 feeb2
- 4G LTE: 27 feeb3
- Gigabit LTE: 61 seconds4
- 5G: 35 seconds5
Nco ntsoov tias cov lej no tsuas yog qhov nruab nrab xwb. Yog tias koj qhov kev sib txuas 5G tau mus txog qhov nrawm ntawm 20 Gb / s, tib cov yeeb yaj kiab tuaj yeem khaws cia hauv ib lub qhov muag, hauv ib pliag xwb.
Ceev 5G- Tiag?
Ntawm no yog qee qhov piv txwv ntawm nws yuav siv sijhawm ntev npaum li cas txhawm rau rub tawm cov ntaub ntawv sib txawv ntawm 5G network, piv txwv li qhov sib txawv:
- 1 Gb/s: Ob vib nas this los rub tawm 75-j.webp" />
- 5 Gb/s: Yim vib nas this los rub tawm ob lub caij nyoog ntawm Lub Chaw Haujlwm (ib puag ncig 5 GB) dhau ntawm Netflix
- 10 Gb/s: Txog rau 6 vib nas this los cawm koj tus phooj ywg lub tsev movie (8 GB)
- 15 Gb/s: Ib feeb los rub tawm 105 GB archive ntawm koj cov ntaub ntawv thaub qab online
- 20 Gb/s: Hauv ob feeb mus rub tawm Avatar: Tshwj Xeeb Edition (276 GB)
Tau kawg, tag nrho koj cov haujlwm hauv online tau nrawm dua ntawm 5G, tab sis saib cov ntaub ntawv loj heev, zoo li hauv cov piv txwv saum toj no, qhia tau tias cov khoom nrawm npaum li cas tuaj yeem ua tau ntawm 5G.
Koj tuaj yeem pom koj tus kheej seb lub sijhawm rub tawm yuav yog rau cov ntaub ntawv nrog Omni Tshuab xam zauv.
1) Yog tias qhov kev sib txuas 3G nruab nrab yog 6 Mb / s (0.75 MB / s), 3 GB cov ntaub ntawv (3, 072 MB) yuav siv sijhawm ntev li ib teev los rub tawm (3072 / 0.75 / 60).
2) Nrog qhov nruab nrab rub tawm ceev ntawm 10 Mb / s (1.25 MB / s), 3 GB movie (3, 072 MB) tuaj yeem rub tawm tag nrho hauv tsuas yog 40 feeb (3072 /1.25/60).
3) Muab 15 Mb / s (1.87 MB / s) nruab nrab rub tawm ceev rau 4G LTE, koj tuaj yeem rub tawm 3 GB cov ntaub ntawv (3, 072 MB) hauv tsuas yog 27 feeb (3072/1.87/60)..
4) Nrog 400 Mb / s (50 MB / s) rub tawm nrawm, 3 GB cov ntaub ntawv (3, 072 MB) yuav siv sijhawm dhau ib feeb los rub tawm (3072/50).
5) Piv txwv tias rub tawm ceev ntawm 700 Mb / s (87.5 MB / s), 3 GB cov ntaub ntawv (3, 072 MB) tuaj yeem rub tawm hauv 35 vib nas this (3072 / 87.5).
