Hauv 2018, WiFi Alliance tshaj tawm WiFi 6, lub cim tshiab, sai dua ntawm WiFi uas tsim tawm ntawm cov txheej txheem qub (802.11ac thev naus laus zis).Tam sim no, tom qab pib lees paub cov cuab yeej hauv lub Cuaj Hli 2019, nws tau los txog nrog lub npe tshiab uas nkag siab yooj yim dua li cov npe qub.
Qee hnub nyob rau yav tom ntej, ntau ntawm peb cov khoom siv txuas nrog yuav yog WiFi 6 enabled.Piv txwv li, Apple iPhone 11 thiab Samsung Galaxy Notes twb txhawb WiFi 6, thiab peb tau pom Wi-Fi CERTIFIED 6™ routers tsis ntev los no tshwm sim.Peb tuaj yeem xav li cas nrog tus qauv tshiab?
Cov thev naus laus zis tshiab muab kev sib txuas txhim kho rau WiFi 6 cov cuab yeej siv tau thaum tswj kev rov qab sib raug zoo rau cov khoom qub.Nws ua haujlwm zoo dua nyob rau hauv ib puag ncig ntau dua, txhawb nqa lub peev xwm ntawm cov khoom siv, txhim kho lub roj teeb lub neej ntawm cov khoom siv sib xws, thiab khav theeb cov ntaub ntawv hloov pauv ntau dua li cov neeg ua ntej.
Ntawm no yog ib qho kev tawg ntawm cov qauv yav dhau los.Nco ntsoov tias cov laus versions tau raug xaiv nrog cov txheej txheem npe tshiab, txawm li cas los xij, lawv tsis siv dav ntxiv lawm:
WiFi 6txhawm rau txheeb xyuas cov khoom siv uas txhawb nqa 802.11ax (tso tawm 2019)
WiFi 5txhawm rau txheeb xyuas cov khoom siv uas txhawb nqa 802.11ac (tso tawm 2014)
WiFi 4txhawm rau txheeb xyuas cov khoom siv uas txhawb nqa 802.11n (tso tawm 2009)
WiFi 3txhawm rau txheeb xyuas cov khoom siv uas txhawb nqa 802.11g (tso tawm 2003)
WiFi 2txhawm rau txheeb xyuas cov khoom siv uas txhawb nqa 802.11a (tso tawm xyoo 1999)
WiFi 1txhawm rau txheeb xyuas cov khoom siv uas txhawb nqa 802.11b (tso tawm xyoo 1999)
WiFi 6 vs WiFi 5 ceev
Ua ntej, cia peb tham theoretical throughput.Raws li Intel tau hais tias, "Wi-Fi 6 muaj peev xwm ua tau siab tshaj plaws ntawm 9.6 Gbps thoob plaws ntau txoj kev, piv rau 3.5 Gbps ntawm Wi-Fi 5."Hauv txoj kev xav, WiFi 6 muaj peev xwm router tuaj yeem ntaus nrawm dua 250% sai dua li tam sim no WiFi 5 khoom siv.
WiFi 6 lub peev xwm siab dua yog ua tsaug rau thev naus laus zis xws li orthogonal zaus faib ntau yam nkag (OFDMA);MU-MIMO;beamforming, uas ua rau cov ntaub ntawv ntau dua ntawm qhov muab ntau ntxiv kom muaj peev xwm hauv lub network;thiab 1024 quadrature amplitude modulation (QAM), uas ua rau muaj kev nce ntxiv rau qhov tshwm sim, kev siv bandwidth siv los ntawm kev siv cov ntaub ntawv ntau dua hauv tib qhov spectrum.
Thiab tom qab ntawd muaj WiFi 6E, xov xwm zoo rau kev sib txuas hauv network
Lwm qhov ntxiv rau WiFi "kho kom zoo dua" yog WiFi 6E.Thaum Lub Plaub Hlis 23, FCC tau txiav txim siab keeb kwm los tso cai tshaj tawm tsis pub tshaj 6GHz band.Qhov no ua haujlwm tib yam li koj lub router hauv tsev tuaj yeem tshaj tawm tshaj 2.4GHz thiab 5GHz bands.Tam sim no, WiFi 6E cov cuab yeej muaj peev xwm muaj cov pab pawg tshiab nrog tag nrho cov txheej txheem tshiab ntawm WiFi kom txo qis kev sib koom tes thiab poob cov cim:
"6 GHz chaw nyob Wi-Fi spectrum tsis txaus los ntawm kev muab cov spectrum sib txuas kom haum rau 14 ntxiv 80 MHz channels thiab 7 ntxiv 160 MHz channels uas xav tau rau cov ntawv thov bandwidth siab uas xav tau cov ntaub ntawv nrawm dua xws li cov ntsiab lus video streaming thiab virtual kev muaj tiag. . Wi-Fi 6E cov khoom siv yuav ua kom cov kab dav dav dua thiab muaj peev xwm ntxiv kom xa cov kev ua tau zoo dua hauv lub network. "- WiFi Alliance
Qhov kev txiav txim siab no yuav luag plaub npaug ntawm qhov bandwidth uas muaj rau kev siv WiFi thiab IoT cov khoom siv - 1,200MHz ntawm spectrum hauv 6GHz band muaj rau kev siv tsis muaj ntawv tso cai.Txhawm rau muab qhov no rau hauv qhov kev xav, 2.4GHz thiab 5GHz bands ua ke tam sim no ua haujlwm nyob rau hauv li 400MHz ntawm qhov tsis muaj ntawv tso cai spectrum.
