5G yog lub xov tooj tshiab tshaj plaws uas tau hloov 4G thev naus laus zis los ntawm kev muab ntau yam kev txhim kho hauv kev nrawm, kev pabcuam, thiab kev ntseeg siab.
Vim 5G?
Lub hom phiaj tseem ceeb thiab yog vim li cas xav tau kev hloov kho network yog txhawm rau txhawb nqa cov khoom siv ntau ntxiv uas xav tau kev siv internet, ntau ntawm lawv xav tau ntau bandwidth ua haujlwm ib txwm ua 4G tsuas tsis txiav nws ntxiv lawm.
Rau siv, xav txog ntev npaum li cas peb tau siv 4G; thawj lub 4G network tau tshaj tawm hauv 2009. Networks hnub no (txog lig 2021) nqa ncig 300 npaug ntau dua li lawv tau ua hauv 2011.
5G siv ntau hom kav hlau txais xov, ua haujlwm ntawm cov xov tooj cua sib txawv, txuas ntau yam khoom siv hauv Is Taws Nem, txo qis qeeb, thiab xa cov nrawm nrawm.
5G Ua haujlwm txawv dua li 4G
Ib hom tshiab ntawm lub xov tooj ntawm tes yuav tsis yog qhov tshiab yog tias nws tsis yog, qee txoj hauv kev, qhov txawv ntawm cov uas twb muaj lawm. Ib qhov sib txawv hauv qab yog 5G kev siv cov xov tooj cua tshwj xeeb kom ua tiav qhov 4G tes hauj lwm ua tsis tau.
Lub xov tooj cua spectrum tau tawg mus rau hauv pawg, txhua tus muaj cov yam ntxwv tshwj xeeb thaum koj tsiv mus rau ntau dua. 4G siv zaus qis dua 6 GHz, thaum qee lub 5G tes hauj lwm siv ntau zaus, xws li nyob ib ncig ntawm 30 GHz lossis ntau dua.
Cov zaus siab no yog qhov zoo rau ntau qhov laj thawj, ib qho tseem ceeb tshaj plaws uas lawv txhawb nqa lub peev xwm loj rau cov ntaub ntawv ceev. Tsis tsuas yog lawv tsis tshua muaj cluttered nrog cov ntaub ntawv xov tooj ntawm tes uas twb muaj lawm, thiab yog li tuaj yeem siv tau yav tom ntej rau kev nce bandwidth xav tau, lawv kuj tseem muaj kev taw qhia siab thiab tuaj yeem siv sab xis ntawm lwm cov teeb liab wireless yam tsis muaj kev cuam tshuam.
Qhov no txawv heev ntawm 4G yees uas tua cov ntaub ntawv nyob rau hauv tag nrho cov kev taw qhia, muaj peev xwm nkim lub zog thiab lub zog rau beam xov tooj cua nthwv dej ntawm qhov chaw uas tsis txawm thov mus rau hauv internet.
5G kuj tseem siv luv luv wavelengths, uas txhais tau hais tias cov kav hlau txais xov tuaj yeem me dua li cov kav hlau txais xov uas twb muaj lawm thaum tseem muab kev tswj xyuas meej. Txij li thaum ib lub hauv paus chaw nres tsheb tuaj yeem siv cov kav hlau txais xov ntau dua, nws txhais tau tias 5G tuaj yeem txhawb nqa ntau dua 1,000 ntau yam khoom siv hauv ib lub 'meter' dua li qhov kev txhawb nqa los ntawm 4G.
txhua qhov no txhais tau li cas yog tias 5G tes hauj lwm tuaj yeem tshaj tawm cov ntaub ntawv ceev ceev rau ntau tus neeg siv, nrog rau qhov siab thiab qis qis.
Txawm li cas los xij, feem ntau ntawm cov kev ua haujlwm siab tshaj plaws no tsuas yog ua haujlwm yog tias muaj qhov tseeb, ncaj qha-ntawm-pom ntawm lub kav hlau txais xov thiab lub cuab yeej tau txais lub teeb liab. Dab tsi ntxiv yog tias qee qhov ntawm cov zaus no tau yooj yim nqus los ntawm cov av noo, nag, thiab lwm yam khoom, txhais tau tias lawv tsis mus deb.
Nws yog rau cov laj thawj no uas muaj kev sib txuas 5G muaj zog nyob qhov twg koj tuaj yeem poob qis mus rau 4G nrawm thaum koj taug kev ob peb taw deb. Ib txoj hauv kev no tau hais txog yog los ntawm kev siv cov kav hlau txais xov zoo, xws li cov me me hauv cov chav tshwj xeeb lossis cov tsev uas xav tau lawv, lossis cov loj loj nyob thoob plaws hauv lub nroog.
Raws li 5G nthuav dav, yuav tsum muaj ntau qhov chaw rov ua dua los thawb lub xov tooj cua kom deb li deb tau los muab kev txhawb nqa 5G ntev.
Lwm qhov txawv ntawm 5G thiab 4G yog tias cov tes hauj lwm tshiab tuaj yeem nkag siab tau yooj yim dua cov ntaub ntawv thov, thiab tuaj yeem hloov mus rau hauv qis zog hom thaum tsis siv lossis thaum muab tus nqi qis rau cov khoom siv tshwj xeeb, tab sis tom qab ntawd hloov mus rau lub zog siab dua rau cov khoom xws li HD video streaming. Qhov tseeb, raws li qee qhov kev tshawb fawb, 5G yog ntau npaum li 90 feem pua sib zog ntau dua li cov laus xws li 4G.
5G Yog nrawm dua 4G
Bandwidth yog hais txog tus nqi ntawm cov ntaub ntawv uas tuaj yeem txav tau (uploaded lossis rub tawm) los ntawm lub network dhau lub sijhawm. Qhov no txhais tau hais tias nyob rau hauv cov xwm txheej zoo tshaj plaws thaum muaj tsawg heev yog tias muaj lwm yam khoom siv lossis cuam tshuam los cuam tshuam rau qhov nrawm, lub cuab yeej tuaj yeem ua raws li qhov xav tau los ua qhov ceev ceev.
Los ntawm qhov kev xav ceev ceev, 5G yog 20 npaug nrawm dua 4GQhov no txhais tau hais tias thaum lub sij hawm nws coj mus download tau ib daim ntawm cov ntaub ntawv nrog 4G (zoo li ib tug yeeb yam), tib yam yuav tau downloaded 20 zaug nyob rau hauv ib tug 5G network. Saib lwm txoj hauv kev: koj tuaj yeem rub tawm ze li 10 cov yeeb yaj kiab ua ntej 4G tuaj yeem xa tawm txawm tias thawj ib nrab ntawm ib qho!
5G muaj qhov tsawg kawg nkaus download ceev ntawm 20 Gbps thaum 4G zaum ntawm 1 Gbps xwb. Cov lej no hais txog cov khoom siv uas tsis txav mus los, zoo li hauv kev teeb tsa wireless nkag (FWA), qhov twg muaj kev sib txuas ncaj qha ntawm lub xov tooj ntawm tes thiab tus neeg siv lub cuab yeej. Kev nrawm sib txawv thaum koj pib tsiv, xws li hauv tsheb lossis tsheb ciav hlau.
Txawm li cas los xij, cov no feem ntau tsis yog hu ua "ib txwm" nrawm uas cov cuab yeej tau ntsib, vim tias feem ntau muaj ntau yam cuam tshuam rau bandwidth. Hloov chaw, nws tseem ceeb dua los saib qhov nrawm nrawm, lossis qhov nruab nrab ntsuas bandwidth.
5G kev pab them nqi nce mus tas li, tab sis feem ntau tib neeg tej zaum tseem tsis muaj 5G-theem nkag mus tau txhua lub sijhawm, yog li nws tsis ncaj ncees los tawm tswv yim txog kev rov ua dua lub ntiaj teb tiag tiag. Uas tau hais tias, qee cov ntawv tshaj tawm qhia txhua hnub rub tawm nrawm ntawm 100 Mbps, tsawg kawg (Verizon qhov kev pabcuam hauv tsev 5G xa cov ntaub ntawv ntawm 300 Mbps txog 1 Gbps).
5G Ua Li Cas 4G Ua Tsis Tau?
Muab qhov sib txawv me ntsis ntawm lawv ua li cas, nws pom tseeb tias 5G tab tom taug kev tshiab rau yav tom ntej rau cov khoom siv txawb thiab kev sib txuas lus, tab sis qhov ntawd txhais tau li cas rau koj?
Lub network txuas ntxiv no tseem tso cai rau koj xa ntawv, hu xov tooj, xauj hauv internet, thiab tshaj tawm cov yeeb yaj kiab. Qhov tseeb, tsis muaj dab tsi koj tam sim no ua hauv koj lub xov tooj, hais txog Is Taws Nem, raug tshem tawm thaum koj siv 5G-lawv nyuam qhuav txhim kho.
Lub vev xaib thauj khoom sai dua, online multiplayer games tsis lag luam ntau, muaj cov yeeb yaj kiab du thiab muaj tseeb thaum siv FaceTime, thiab lwm yam.
5G nrawm heev uas txhua yam koj ua hauv Is Taws Nem tam sim no uas zoo li nrawm tuaj yeem tshwm sim sai sai.
Yog tias koj siv 5G hauv tsev los hloov koj lub cable, koj yuav pom tias koj tuaj yeem txuas ntxiv koj cov khoom siv hauv internet tib lub sijhawm yam tsis muaj teeb meem bandwidth. Qee qhov kev sib txuas hauv Is Taws Nem hauv tsev qeeb heev uas lawv tsuas yog tsis txhawb nqa txhua qhov kev sib txuas tech tshiab tawm hnub no.
5G hauv tsev cia koj txuas koj lub xov tooj smartphone, wireless ntsuas kub, video game console, ntse xauv, lub mloog pob ntseg virtual, wireless kev ruaj ntseg koob yees duab, ntsiav tshuaj, thiab laptop tag nrho rau tib lub router yam tsis muaj kev txhawj xeeb tias lawv yuav tsis ua haujlwm thaum lawv txhua tus nyob rau tib lub sijhawm.
Qhov twg 4G ua tsis tiav ntawm kev muab tag nrho cov ntaub ntawv xav tau rau ntau lub xov tooj ntawm tes, 5G qhib lub dav hlau rau ntau lub vev xaib siv thev naus laus zis xws li teeb pom kev zoo, wireless sensors, mobile wearables, thiab tsheb sib txuas lus..
Lub tsheb uas tau txais cov ntaub ntawv GPS thiab lwm cov lus qhia uas pab lawv taug txoj kev, xws li software hloov tshiab lossis kev ceeb toom tsheb khiav thiab lwm cov ntaub ntawv hauv lub sijhawm, xav tau internet ceev kom ib txwm nyob saum-nws tsis yog qhov xav tau tiag tiag. Tag nrho cov no tuaj yeem txhawb nqa los ntawm 4G networks.
Vim 5G tuaj yeem nqa cov ntaub ntawv sai dua li 4G tes hauj lwm, nws tsis yog tawm ntawm qhov muaj peev xwm cia siab tias yuav pom ntau cov ntaub ntawv nyoos, tsis muaj kev hloov pauv ib hnub. Qhov no txhais tau tias txawm tias nkag tau sai dua rau cov ntaub ntawv, vim nws tsis tas yuav tsum tau muab tshem tawm ua ntej siv.
5G Muaj nyob qhov twg?
Koj tseem tsis tuaj yeem siv txhua hom 5G tes hauj lwm nyob txhua qhov chaw koj mus (zoo li koj tuaj yeem ua tau nrog 4G) vim tias kev tshaj tawm yog txheej txheem txuas ntxiv. Koj tuaj yeem txuas rau hom nrawm dua hauv cov cheeb tsam uas muaj neeg coob coob, tab sis tsuas yog hom qeeb qeeb (lossis tsis muaj dab tsi) hauv feem ntau ntawm cov nroog lossis cov zej zog nyob deb nroog. Qhov no txhais tau tias, txawm tias koj muaj 5G xov tooj, muaj ntau qhov chaw loj uas koj tsis tuaj yeem tau txais kev pabcuam tom ntej.
Hnub tso tawm rau 5G tsis tau teeb tsa hauv pob zeb rau txhua tus neeg muab kev pabcuam lossis lub tebchaws, tab sis ntau tus tau muab rau ob peb xyoos tam sim no thiab yuav txuas ntxiv nthuav lawv cov tes hauj lwm mus rau yav tom ntej, txawm tias cov thev naus laus zis tshiab, xws li 6G, ua lawv lub xub ntiag.
