Raws xyoo kev tshawb fawb thiab kev tshawb fawb hauv Internet cov cuab yeej siv thiab cov kev daws teeb meem hauv tsev Broadband Internet zoo tshaj lij. Ua ntej, nws ntsuas qhov teeb meem ntawm lub tsev broadband sab hauv tsev zoo, thiab cov kev ua haujlwm uas ua rau lub tsev broadband nyob sab hauv tsev. Thib ob, tus tshiab sab hauv tsev pab them nqi kho mob cim los ntawm Wi-Fi 6 thiab FTTR (fiber ntau rau hauv chav).
1. Kev txheeb xyuas ntawm lub tsev broadband sab hauv tsev txawb teeb meem
Nyob rau hauv cov txheej txheem ntawm FTTH (fiber-rau-tsev), vim muaj kev cuam tshuam kho qhov muag thiab kev sib txuas siv kho qhov muag tau txais los ntawm lub rooj vag tsis tshua muaj siab thiab tus nqi yuam kev tsawg thiab Ua siab loj, uas ua rau muaj kev nce ntxiv hauv pob ntawv poob ntawm cov txheej txheem sib kis cov txheej txheem sab saud. , tus nqi poob.
Txawm li cas los xij, kev ua tau zoo ntawm cov rooj loog qub feem ntau yog qhov muaj txiaj ntsig zoo xws li tshwm sim, ua rau muaj kev sib tsoo thiab kev sib tsoo ntawm cov rooj sib tw. Cov rooj vag qub feem ntau tsis txhawb nqa kev sib tw, thiab qee qhov chaw sib tw qub Tus neeg siv kev kawm online. Tam sim no, tus Qub Ntse SNtwon Gateways uas tau raug siv rau 3 xyoos lossis ntau dua nyob rau hauv lub network nyob tseem nyob ib qho kev faib ua feem thiab xav tau hloov.
Lub 2.4GHz Nquag Band yog Ism (Industrial-kev tshawb fawb-kev kho mob) zaus. Nws yog siv los ua ib qho zaus band rau xov tooj cua xws li cov chaw siv hluav taws xob hauv nroog, nrog rau kev sib txuas lus tsis zoo, nrog qee qhov chaw pab thiab tsawg bandwidth. Tam sim no, tseem muaj qee qhov feem ntawm cov rooj sib tw txhawb nqa rau cov network uas nyob ib sab yog ntau qhov tseem ceeb.
Vim tias cov xim ntsuab thiab cov khoom ua tau zoo tsis txaus ntawm qee qhov rooj vag, PPPoe sib txuas muaj zog thiab cov nyom tau cuam tshuam rau cov neeg siv. Tom qab PPPoe kev txuas yog kis tau dhau los (piv txwv li UPLink cov ntawv txuas tau cuam tshuam), txhua lub rooj loog chaw nres nkoj yuav tsis sib xws thiab rov ua dua pppoe dialing. Qee cov tuam ntxhab 'lub rooj vag saib ib zaug li 20 vib nas this, thiab redial tsuas yog tom qab 30 tsis tau muaj kev kuaj pom. Raws li qhov tshwm sim, nws siv sijhawm li 10 feeb rau lub rooj vag mus rau kev pib ua pppoe replay tom qab mus offline, muaj feem cuam tshuam cov neeg siv kev paub.
Ntau thiab ntau tus neeg siv khoom siv lub rooj vag hauv tsev tau teeb tsa nrog cov routers (ntawm nohafter raug xa mus rau "routers"). Ntawm cov rhawv no, ob peb tsuas yog txhawb 100m wan ports, lossis (thiab) tsuas yog txhawb nqa Wi-nkaus 4 (802.11b / g / n).
Some manufacturers' routers still have only one of the WAN ports or Wi-Fi protocols that supports Gigabit network speeds, and become “pseudo-Gigabit” routers. Tsis tas li ntawd, lub router txuas nrog lub rooj vag los ntawm lub network cable, thiab lub network 5 lossis ceev dua los tiv thaiv kev cuam tshuam thiab feem ntau ntawm lawv nkaus xwb Txhawb 100m ceev. Tsis muaj ib qho ntawm cov rouches saud thiab cov khoom siv network tuaj yeem ua tau raws li cov kev xav tau hloov kho kev hloov pauv ntawm cov tes hauj lwm tom ntej thiab cov tes hauj lwm super-gigamps. Qee tus routers rov pib dua vim yog cov teeb meem khoom muaj txiaj ntsig zoo, cuam tshuam rau cov neeg siv kev paub.
Wi-Fi yog cov qauv tseem ceeb hauv sab hauv, tab sis ntau cov rooj vag hauv tsev uas tsis muaj chaw nyob hauv tus neeg siv lub qhov rooj. Txwv los ntawm qhov chaw nyob ntawm lub thawv tsis muaj zog tam sim no, cov khoom ntawm lub hau, thiab hom phiaj xwm tsev nyhav, WI-FI teeb liab tsis txaus los npog txhua qhov chaw nyob sab hauv tsev. Lub davhlau ya nyob twg yog los ntawm Wi-nkaus nkag mus, ntau cov nyom muaj, thiab qhov ntau dua lub teeb liab muaj zog, uas yuav ua rau tsis ruaj ntseg txuas thiab pob pob ntawv poob.
Nyob rau hauv rooj plaub ntawm sab hauv network ntawm ntau yam Wi-Fi cov teeb meem thiab cov teeb meem sib cuam tshuam thiab muaj kev cuam tshuam ntawm cov chaw uas tsis tsim nyog, ntxiv rau Wi-nkaus tus nqi.
Thaum qee cov neeg siv txuas lub router mus rau lub rooj vag, vim tias tsis muaj kev paub txog lub rooj vag rau lub network sib txuas, ua rau muaj kev sib tw ntawm cov chaw nres nkoj. Hauv cov xwm txheej no, txawm tias cov neeg siv cov ntaub ntawv xa mus rau cov kev pabcuam gigabes lossis siv cov kev pabcuam gigus, nws tsis tuaj yeem tau txais cov kev sib tw ua haujlwm uas muaj kev sib tw nrog kev ua txhaum.
Qee tus neeg siv tau muaj ntau cov khoom siv sib txuas nrog Wi-nkaus hauv lawv lub tsev (ntau dua 20) lossis ntau daim ntawv thov ceev tib lub sijhawm, uas tseem yuav ua rau muaj kev tsis sib haum xeeb thiab tsis muaj kev sib txuas ntawm Wi-FI.
Qee tus neeg siv siv cov chaw nres tsheb qub uas tsuas yog txhawb nqa ib zaug Wi-Fi-Fi-Fi-Fi-Fi-Fi-Fi-Fi-Fi-Fi-Fi-Fi-Fi-Fi-Fi kev cai lij choj, yog li lawv tsis tuaj yeem tau txais kev ruaj khov thiab nrawm.
2. Cov thev naus laus zis tshiab los txhim kho sab hauv tsev network zoo
High-bandwidth, cov kev pab latency xws li 4k / 8K High-Education Video, Ar / Kev Kawm Txuj Ci hauv tsev kuj maj mam ua rau Rigid xav tau ntawm cov neeg siv tsev. Qhov no tso rau yav tom ntej cov qib siab yuav tsum tau ua rau qhov zoo ntawm lub tsev broadband network, tshwj xeeb tshaj yog qhov zoo ntawm lub tsev broadband sab hauv tsev. Lub tsev uas twb muaj lawm Broadband nyob sab hauv tsev sab hauv tsev raws li FTTH (Fiber rau hauv tsev, fiber rau hauv tsev) yog qhov nyuaj kom tau raws li cov cai saum toj no. Txawm li cas los xij, Wi-Fi 6 thiab FTTR cov thev naus laus zis tuaj yeem ua tau zoo dua cov kev pabcuam ua kom tiav saum toj no thiab yuav tsum tau xa tawm ntawm lub nplai loj kom sai li sai tau.
Wi-Fi 6
Xyoo 2019, Wi-nkaus Alliance muaj npe hu ua 802.11ax Tshuab Wi-Fi 6, thiab muaj npe yav dhau los 802.11n thev naus laus zis wi-nkaus. Thiab Wi-Fi 4 feem.
Wi-Fi 6 qhia txog FDMA (Orthoe Furnity Faib ntau qhov kev nkag tau), multi-multo-internet ntau cov zis ntau yam kev nkag tau), 1024qam (QuadRRIDATURate amplitude Kev hloov kho, quadtrature golditive tshuab) thiab lwm yam tshiab thev naus laus zis, theoretical ntau download tus nqi tuaj yeem ncav cuag 9.6gbit / s. Piv nrog cov feem ntau siv wi-fi 4 thiab wi-fi 5 thev naus laus zis hauv kev lag luam, nws muaj peev xwm nce qib siab dua, muaj kev pab cuam qis dua, kev tiv thaiv dav dav thiab muaj zog me me. Tau noj.
FTTR Technology
FTTR yog hais txog kev xa tawm ntawm txhua qhov chaw sib tw onecing thiab cov khoom siv kho mob rau cov neeg siv khoom siv los ntawm Pon Technology.
Lub rooj vag fttr cac yog qhov tseem ceeb ntawm FTTR network. Nws txuas rau upward rau lub olt kom muab fiber-rau-hauv-tsev, thiab downward los muab cov chaw nres nkoj kho qhov muag kom txuas ntau yam FTTR cov kab ke sib tw. FTTR cov qhev mus sib txuas nrog cov khoom siv davhlau ya nyob twg los ntawm cov khoom siv titterway, thiab lees txais kev tswj hwm thiab tswj hwm ntawm FTTR lub rooj vag hauv FTTR lub rooj vag. FTTR tes haujlwm yog qhia hauv daim duab.
Piv nrog cov qauv ib txwm muaj xws li network cable network, thiab wireless network networking, thiab wireless networking, fttr networks muaj cov txiaj ntsig hauv qab no.
Ua ntej, cov cuab yeej siv network tau muaj kev ua tau zoo dua thiab bandwidth ntau dua. Lub rooj vag kho qhov muag ntawm tus tswv lub rooj vag tuaj yeem txuas tus neeg siv khoom ntawm tus neeg siv, thiab txhim kho qhov zoo ntawm tus neeg siv tsev hauv txhua qhov. FTTR network muaj ntau ntxiv rau kev sib kis bandwidth thiab ruaj khov.
Qhov thib ob yog zoo dua Wi-nkaus kev pab them nqi thiab siab dua. Wi-Fi 6 yog tus qauv kev teeb tsa ntawm FTTR rooj vag thiab ob lub rooj vag uas muaj peev xwm siv tau Wi-nkaus kev ruaj ntseg ntawm Wi-nkaus network thiab teeb liab pab cuam lub zog.
Qhov zoo tshaj ntawm Tsev Network Intranet cuam tshuam los ntawm cov yam xws li lub tsev network network, cov cuab yeej siv cov neeg siv khoom, thiab cov neeg siv cov lus qhia. Yog li ntawd, nrhiav thiab nrhiav qhov tsis zoo ntawm lub network network yog qhov teeb meem nyuaj ntawm lub network nyob. Txhua lub tuam txhab kev sib txuas lus lossis tus muab kev pabcuam hauv network muab nws txoj kev daws teeb meem feem ntau. Piv txwv li, kev daws teeb meem rau kev ntsuas qhov zoo ntawm lub tsev network intranet thiab nrhiav qhov tsis zoo; Txuas ntxiv tshawb cov ntawv thov cov ntaub ntawv loj thiab kev txawj ntse thev naus laus zis hauv kev txhim kho hauv tsev loj hauv tsev; Txhawb nqa daim ntawv thov ntawm FTTR thiab Wi-Fi 6 Technology thoob rau network zoo thiab ntau dua.
