WiFi yog WLAN thev naus laus zis raws li IEEE 802.11. Yog li ntawd, 802.11n yog lub npe WiFi 4. WiFi 5 thiab WiFi 6 kuj sawv cev rau IEEE 802.ac thiab IEEE 802.ax, feem. WiFi 6 yog tsim los ntawm WiFi 5, nrog rau kev ua tau zoo dua. Niaj hnub no, muaj ntau dua thiab ntau dua WiFi cov khoom siv hauv khw. WiFi 6 yuav dhau los ua qhov tseem ceeb nyob rau yav tom ntej. Tab sis tam sim no, vim muaj teeb meem kev lag luam, nws kuj yog ib qho nyuaj rau qee qhov kev lag luam los txhim kho lawv cov khoom los txhawb WiFi 6. Thaum qhov teeb meem tau daws lawm, WiFi 6 yuav npog txhua yam ntawm peb lub neej. Nws yog pom tseeb tias WiFi 6 yog superior rau WiFi 5. Hauv tsab xov xwm no, peb yuav qhia qhov zoo ntawm WiFi 6 tshaj WiFi 5.
Vim li cas WiFi 6 zoo dua WiFi 5?
1. Ceev
Piv rau WiFi 5, qhov siab tshaj plaws kev sib kis ceev ntawm WiFi 6 mus txog 9.6Gbps, uas yog peb npaug ntawm qhov ceev ntawm WiFi 5. Yog tias peb hloov 9.6Gbps rau qhov kev rub tawm ceev uas peb tau siv, nws yuav yog 1228.8MB / s lossis 1.2 GB. /s.
Nco ntsoov:
Qhov ceev peb tau hais ntawm no yog hais txog qhov ceev uas koj txuas cov khoom siv xws li xov tooj ntawm tes lossis khoos phis tawj mus rau routers, tsis yog qhov ceev hauv Is Taws Nem. Yog tias koj qhov broadband ceev tsawg, WiFi 6 tsis tuaj yeem txhim kho koj lub internet ceev. Tab sis WiFi 6 yog qhov sib txawv ntawm kev sib kis ntawm LAN.
2. zaus
Raws li rau zaus, WiFi 5 tsuas txhawb 5GHz, thaum WiFi 6 npog 2.4GHz thiab 5GHz. Raws li paub zoo, qhov kev pab them nqi ntawm WiFi teeb liab nqaim nrog nce zaus. Yog li ntawd, 5GHz sai dua 2.4GHz, tab sis npog thaj tsam me dua. WiFi 6 dual band, 2.4GHz kev pab them nqi rau thaj chaw loj, thiab 5GHz rau kev nrawm dua.
3. Ua tau zoo thiab latency
Piv nrog rau WiFi 5, qhov kev hloov pauv loj tshaj ntawm WiFi 6 yog nws qhov kev ua tau zoo dua qub thiab txo qis latency. Rau 802.11 a / b / g / n, lawv siv OFDM ua cov kev daws teeb meem loj. Txawm li cas los xij, WiFi 6 tau txhim kho nws mus rau OFDMA, uas tuaj yeem muab kev pabcuam rau ntau tus neeg siv ib txhij.
Qhov tseem ceeb tshaj, cov ntaub ntawv spatial ntawm WiFi 6 tau nce los ntawm 4 mus rau 8, qhia tias WiFi 6 tuaj yeem txhawb nqa txog 8 x 8 MU-MIO. Qhov nruab nrab latency ntawm WiFi 6 yog 20ms, uas yog 10ms qis dua WiFi 5. Yog li ntawd, nws zoo heev txhim kho efficiency thiab txo latency. Is Taws Nem tuaj yeem khaws ntau yam khoom siv txuas nrog routers ruaj khov.
4. Kev nyab xeeb
WiFi 6 txais WPA 3. Nyob rau xyoo 2018, lub koom haum WiFi tau tshaj tawm cov txheej txheem encryption txuas ntxiv WPA 3, uas tau hloov kho dua los ntawm WPA 2 yav dhau los. WPA 3 qhov kev ruaj ntseg tau raug txhim kho, tso cai rau kev tiv thaiv zoo dua ntawm brute force cracking.
5. Kev siv hluav taws xob
Hom kev ua haujlwm ntawm WiFi 5 yog tias thaum lub davhlau ya nyob twg ntaus ntawv xa cov ntaub ntawv mus rau lub router, lwm yam khoom siv tau tos tsis zoo kom tau txais cov ntaub ntawv. Qhov txawv, WiFi 6 tau qhia txog lub tshuab tshiab hu ua TWT. Qhov no txhais tau hais tias thaum ib lub cuab yeej ua haujlwm, lwm yam khoom siv yuav nkag mus rau hom kev pw tsaug zog, txo qis kev siv hluav taws xob thiab ua kom lub roj teeb lub neej ntawm lub cuab yeej.
