5GE thiab LTE tsuas yog ob lub ntsiab lus ntawm ob peb yam uas tau siv los piav txog cov thev naus laus zis tom qab dab tsi ua rau koj lub xov tooj ntawm tes ua haujlwm. Ntau ntawm peb tau hnov txog LTE ntau xyoo tam sim no, tab sis 5GE yog ib lo lus tshiab qee zaum siv nyob rau hauv cov ntsiab lus ntawm 5G network.
Yog li, qhov twg koj yuav tsum tig mus rau yog tias koj tuaj yeem xaiv lub network nyiam? Puas yog ib qho nrawm dua li lwm tus lossis lawv tsuas yog cov nqe lus lag luam uas tsis txhais tau ntau hauv ntiaj teb tiag?
Kev Tshawb Nrhiav Txhua Yam
- AT&T lub sijhawm rau 4G LTE-A lossis LTE+.
- Kev txhim kho ntawm LTE.
- Peak rub tawm ntau dua peb zaug nrawm li LTE.
- Ib daim ntawv qub ntawm 5GE.
- Feem ntau yuam kev 4G.
- Kev txhim kho dua 3G.
- Slower than 5GE.
Txawm li cas los xij, nyob ntawm seb koj tham nrog leej twg, 5GE thiab LTE tuaj yeem suav tias yog qee qhov sib txawv, lossis txawm tias muaj qhov sib txawv. Lawv ob leeg siv los piav txog tus qauv uas hais txog tej yam xws li kev ceev ntawm lub xov tooj ntawm tes. Ib qho sai dua thiab tshiab dua li lwm qhov.
Ib txoj hauv kev los xav txog cov ntsiab lus no yog pom lawv ntawm qhov spectrum. 5GE yog ib qho kev txhim kho uas mus dhau qhov LTE muaj peev xwm. Tab sis ob qho tib si tseem siv niaj hnub no nyob ntawm qhov chaw koj muaj kev pabcuam hauv xov tooj thiab cov neeg nqa khoom uas koj siv.
Tus Qauv Tshiab: 5GE Yog Tiag 4G, Tab sis LTE Yog 3.9G
- Tseem hu ua LTE-A thiab LTE+.
- Nws suav tias muaj tseeb 4G.
- Hu tsis raug 5G.
- Daim ntawv tsawg dua ntawm 5GE.
- Kev txhim kho dua tus thawj 3G.
- Hu tsis raug 4G.
Ib feem ntawm kev txheeb xyuas hom network twg zoo dua thiab yuav ua li cas 5GE thiab LTE sib txawv cuam tshuam nrog kev tsis sib haum xeeb ntawm 4G jargon. Muab qhov yooj yim: 5GE yog daim ntawv siab tshaj ntawm LTE uas qee zaum mus los ntawm lub npe LTE + lossis LTE-A (rau Advanced). Nws nrawm dua thiab txhim khu kev qha.
Thaum nws tau tshaj tawm thawj zaug, qhov tshwj xeeb xav tau tias rau lub cuab yeej yuav tsum tau 4G-tshaj, nws yuav xav tau qhov kev rub tawm tsawg kawg ntawm 100 Mbps. Thaum cov tuam txhab tsis tuaj yeem ncav cuag qhov tsawg kawg nkaus, lawv tuaj nrog lub sijhawm los piav txog "yuav luag 4G" ceev; ib lub tshuab uas tab tom ua rau muaj tseeb 4G. Nov yog qhov uas 4G Long Term Evolution (4G LTE) yug.
Txawm hais tias nws zoo li 4G LTE yuav tsum zoo dua thiab sai dua 4G vim yog cov ntawv ntxiv, nws yog ib daim ntawv tsawg dua. Koj tuaj yeem xav tias nws yog lub teeb ntawm 4G lossis txawm tias daim ntawv siab tshaj ntawm 3G (nws qee zaum hu ua 3.9G). Nws zaum hauv nruab nrab ntawm ob.
Raws li LTE tau txhim kho raws li, lwm qhov kev siv zog los piav qhia txog cov thev naus laus zis tshiab: 4G LTE Advanced (tseem hu ua 4G LTE-A thiab 4G LTE+). Qhov twg nws tsis meej pem yog tias 4G LTE-A kuj muaj qhov tsawg kawg nkaus rub tawm ceev ntawm 100 Mbps, zoo ib yam li 4G. Yog li, technically, 4G LTE-A tuaj yeem suav tias yog 4G.
Yog li 5GE poob rau qhov twg? Ib yam li LTE siv los piav txog kev hloov pauv mus rau 4G, AT&T siv 5G Evolution los piav txog 4G txoj kev mus rau 5G. Lawv hu nws lub hauv paus thiab launchpad rau 5G. Koj tuaj yeem xav tias nws yog "pre-5G" network.
Lub tswv yim muaj los ua kom zoo li lawv lub network zoo dua li 4G network muab los ntawm lwm lub tuam txhab. Tsuas muaj ib qho teeb meem xwb: ob lo lus yeej zoo ib yam. 4G LTE-A=5GE. Thaum AT&T tso 5GE rau lawv lub xov tooj lossis tham txog 5G Evolution, lawv tau hais txog 4G LTE-A.
Muab tag nrho ua ke nrog cov lus saum toj no hauv siab tam sim no yooj yim dua: 5GE thiab 4G LTE-A yog tib yam, thiab nws tshiab thiab nrawm dua 4G LTE.
Kev Ua Haujlwm: 5GE Yog 3x sai dua
- 1 Gbps ncov rub tawm nrawm.
- 500 Mbps peak upload ceev.
- Latency under 5 ms.
- 300 Mbps siab tshaj rub tawm nrawm.
- 75 Mbps peak upload ceev.
- Latency under 10 ms.
Peb tau kawm tias 5GE tiag tiag tsuas yog hloov pauv 4G LTE-A, yog li cov lus nug tam sim no yog tiag tiag li cas 4G LTE+ thiab 4G LTE txawv li cas.
Muaj ob yam uas tib neeg feem ntau nyiam tshaj thaum nws los txog rau lub network hloov kho tshiab: ceev thiab latency. Zoo li txhua tus qauv tshiab wireless, txhua qhov kev rov ua dua tshiab coj qhov tsawg kawg nkaus ceev thiab latency yuav tsum tau, thiab hloov kho theoretical download thiab upload qhov siab tshaj plaws.
Tsawg kawg qhov kev xav, 4G LTE Advanced yuav tsum muaj peev xwm ncav cuag qhov nrawm ntau zaus siab dua 4G LTE (1,000 Mbps vs 300 Mbps rub tawm nrawm). Thaum muaj kev cuam tshuam, xov tooj ntawm tes load, thiab lwm yam cuam tshuam rau lub ntiaj teb tiag tiag rub tawm thiab uploads uas koj yuav tau txais ntawm ob hom network, LTE +, los ntawm kev txhais, yuav tsum tuaj yeem ntaus nrawm dua thiab qis dua latencies dua LTE.
5GE muaj lwm yam kev txhim kho tshaj li qhov tseeb 4G nrawm, zoo li kev sib txuas ntau dua. Kev hloov pauv tau yooj yim dua thaum koj txav ntawm lub xov tooj ntawm tes thiab lub peev xwm ntau dua rau cov neeg siv ntau dua txhais tau tias tsawg dua kev sib txuas.
Muaj peev xwm ntsuas los ntawm spectral efficiency. LTE's downlink spectral efficiency yog siab li 2.67 ntsis / s / Hz, thaum 5GE's yog 3.7 ntsis / s / Hz. Raws li rau uplink, LTE zaum ntawm 0.08 ntsis / s / Hz thiab 5GE ntawm 0.12 ntsis / s / Hz. Qhov siab dua qhov zoo ntawm no, yog li 5GE yog tus yeej meej.
Cov kav hlau txais xov zoo dua thiab cov chaw nres tsheb hauv paus kuj txhais tau tias 4G LTE-A tes hauj lwm tuaj yeem muab kev pabcuam zoo dua li cov laus.
Kev Txiav Txim Kawg: LTE Tsis Txaus Siab Zoo 5GE
Yog tsis muaj lus nug, 5GE (4G LTE+) yog ib qho kev txhim kho ntawm LTE. Peb pom qhov no nyob rau hauv nws txoj kev ceev thiab kev sib txuas kev ntseeg tau txhim kho. Tsawg latency thiab ceev tshaj plaws ceev txhais tau hais tias koj downloads thiab kwj sai dua.
Tsis zoo li 5G- uas tsis zoo ib yam li 5GE - koj tsis tas yuav tau txais lub xov tooj tshiab "hloov" los ntawm LTE rau LTE +. Koj lub xov tooj feem ntau yuav txhawb nqa ob qho tib si, yog li txuas mus rau lub network sai dua yog qhov yooj yim li siv koj lub xov tooj zoo li qub. Nyob ntawm tus neeg nqa khoom uas koj muaj thiab qhov chaw koj nyob, koj tuaj yeem siv LTE lossis LTE + nyob qhov twg txhua lub sijhawm.
