Qhov siab tshaj plaws theoretical ceev ntawm Wi-Fi network yog qhia los ntawm nws tus qauv Wi-Fi 802.11. Zoo li feem ntau cov khoos phis tawj sib txuas, Wi-Fi txhawb nqa ntau qib kev ua haujlwm, nyob ntawm tus qauv thev naus laus zis. Tam sim no, tus qauv ceev tshaj plaws yog Wi-Fi 6, lub npe uas tau muab rau IEEE 802.11ax wireless standard qhia hauv xyoo 2019. Tus qauv 802.11ax muaj ntau dua, tab sis qhov ntawd yuav sai sai hloov li ntau Wi-Fi 6 li nkag mus rau hauv kev ua lag luam.
Wi-Fi cov qauv tau lees paub los ntawm Lub Tsev Haujlwm ntawm Hluav Taws Xob thiab Hluav Taws Xob Hluav Taws Xob. Txhua tus qauv Wi-Fi raug ntsuas raws li nws qhov siab tshaj plaws theoretical network bandwidth. Txawm li cas los xij, kev ua haujlwm ntawm Wi-nkaus tes hauj lwm tsis phim cov theoretical siab tshaj plaws. Qhov tseeb ceev ntawm Wi-Fi wireless network txuas yog nyob ntawm ntau yam.
Ua ntej koj yuav ib lub router, paub meej tias nws ua haujlwm tam sim no ntawm 802.11 nrog rau ntau qhov kev rov ua dhau los. Cov routers qub, ntawm kev muag khoom pheej yig vim tias lawv tau siv, yuav raug ntsuas tsis siab dua 802.11n lossis ntxov dua.
Theoretical vs. Qhov tseeb Network Ceev
Tam sim no Wi-Fi tes hauj lwm txhawb ntau yam qauv.
Ib qho 802.11b network feem ntau ua haujlwm tsis tau nrawm dua li ntawm 50 feem pua ntawm nws qhov kev xav xav, nyob ib ncig ntawm 5.5 Mbps. Lub 802.11a thiab 802.11g tes hauj lwm feem ntau khiav tsis nrawm dua 20 Mbps. Txawm hais tias 802.11n tus nqi ntawm 600 Mbps piv rau wired Fast Ethernet ntawm 100 Mbps, Ethernet kev sib txuas feem ntau tuaj yeem ua tau zoo tshaj 802.11n hauv kev siv tiag tiag. Txawm li cas los xij, kev ua tau zoo ntawm Wi-Fi txuas ntxiv txhim kho nrog txhua tiam tshiab ntawm thev naus laus zis.
Koj yuav muaj ntau qhov sib txawv ntawm qhov tseeb thiab theoretical ceev ntawm feem ntau Wi-Fi tes hauj lwm tam sim no:
| Nyob zoo | ||
| 802.11b | 11 Mbps | 5.5 Mbps |
| 802.11a | 54 Mbps | 20 Mbps |
| 802.11g | 54 Mbps | 20 Mbps |
| 802.11n | 600 Mbps | 100 Mbps |
| 802.11ac | 1, 300 Mbps | 200 Mbps |
| 802.11ax | 10 Gbps | 2 Gbps |
kab hauv qab
Tus qauv kev sib txuas lus wireless txuas ntxiv yuav yog 802.11be (Wi-Fi 7), zoo li yuav ua tiav los ntawm IEEE hauv 2024. Kev xyaum, txawm li cas los xij, 802.11ax (Wi-Fi 6) tseem nce hauv av tshaj 802.11ac (Wi-Fi 5).
Txoj Cai Limiting Wi-Fi Kev Sib Txuas Ceev
Qhov tsis sib xws ntawm qhov theoretical thiab cov tswv yim Wi-Fi kev ua tau zoo los ntawm kev sib txuas lus hauv xov tooj cua, kev cuam tshuam hauv xov tooj cua, kev cuam tshuam lub cev ntawm cov kab pom ntawm cov khoom siv, thiab qhov kev ncua deb ntawm cov khoom siv.
Ntxiv rau, raws li ntau cov khoom siv sib txuas lus hauv lub network ib txhij, kev ua haujlwm poob qis vim tias bandwidth ua haujlwm li cas thiab cov kev txwv ntawm lub network hardware.
A Wi-Fi network kev sib txuas ua haujlwm ntawm qhov siab tshaj plaws tau ceev uas ob qho tib si, feem ntau hu ua qhov kawg, kev txhawb nqa. Ib qho 802.11g laptop txuas nrog 802.11n router, piv txwv li, kev sib txuas ntawm qhov qis dua ntawm 802.11g laptop. Ob qho khoom siv yuav tsum txhawb nqa tib tus qauv kom ua haujlwm ntawm qhov nrawm dua.
Lub luag haujlwm Internet Cov Chaw Pabcuam Ua Si hauv Network Ceev
Nyob hauv tsev network, kev ua tau zoo ntawm kev sib txuas hauv internet feem ntau yog qhov txwv ntawm qhov kawg-rau-kawg network ceev. Txawm hais tias feem ntau cov chaw nyob hauv zej zog txhawb kev sib koom cov ntaub ntawv hauv tsev ntawm qhov nrawm ntawm 20 Mbps lossis ntau dua, cov neeg siv Wi-Fi tseem txuas rau Is Taws Nem ntawm qhov qis qis uas txhawb nqa los ntawm cov chaw muab kev pabcuam hauv internet.
Feem ntau cov chaw muab kev pabcuam hauv internet muaj ntau theem ntawm kev pabcuam hauv internet. Qhov kev sib txuas ceev dua, koj them ntau dua.
Qhov tseem ceeb ntawm Network Ceev
kev sib txuas ceev ceev tau dhau los ua qhov tseem ceeb dua vim tias streaming video tau muaj koob meej. Tej zaum koj yuav muaj kev tso npe rau Netflix, Hulu, lossis lwm qhov kev pabcuam video-streaming, tab sis yog tias koj qhov kev sib txuas hauv is taws nem thiab lub network tsis tuaj yeem ua tau raws li qhov xav tau ceev tsawg kawg nkaus, koj yuav tsis tau saib ntau cov yeeb yaj kiab.
Ib yam tuaj yeem hais tau rau video streaming apps. Yog tias koj saib TV nrog Roku, Apple TV, lossis lwm yam kev lom zem streaming txuas, koj siv sijhawm ntau ntawm koj lub TV saib hauv apps rau kev lag luam thiab cov kev pabcuam hwm. Yog tias tsis muaj lub network nrawm txaus, cia siab tias yuav muaj kev ua yeeb yaj kiab tsis zoo thiab nquag ncua mus rau qhov tsis zoo.
Piv txwv li, Netflix pom zoo kom muaj kev sib txuas dav dav ntawm 1.5 Mbps, tab sis nws pom zoo kom nrawm dua rau qhov zoo dua: 3.0 Mbps rau SD zoo, 5.0 Mbps rau HD zoo, thiab 25 Mbps rau Ultra HD zoo.
Yuav Ua Li Cas Ntsuas Koj Lub Network Ceev
Koj lub chaw muab kev pabcuam hauv internet tuaj yeem muab qhov kev kuaj xyuas ceev hauv online. Nkag mus rau hauv koj tus account, mus rau nplooj ntawv txuas ceev, thiab ping qhov kev pabcuam. Rov ua qhov kev xeem nyob rau lub sijhawm sib txawv ntawm ib hnub kom txog rau qhov ntsuas nruab nrab.
Yog tias koj lub chaw muab kev pabcuam hauv is taws nem tsis muab qhov ntsuas nrawm, koj tuaj yeem siv ib qho ntawm qhov chaw kuaj dawb hauv internet ceev los ntsuas koj lub network ceev.
