I-advanteji ye-WIFI 6 ONT

Xa kuthelekiswa nezizukulwana zangaphambili zetekhnoloji yeWiFi, ezona mpawu ziphambili zesizukulwana esitsha seWiFi 6 zezi:
Xa kuthelekiswa nesizukulwana sangaphambili se-802.11ac WiFi 5, izinga eliphezulu lokudluliselwa kwe-WiFi 6 liye lanyuswa ukusuka kwi-3.5Gbps yangaphambili ukuya kwi-9.6Gbps, kwaye isantya sethiyori siye sanda malunga namaxesha angama-3.
Ngokubhekiselele kwiibhendi ze-frequency, i-WiFi 5 ibandakanya kuphela i-5GHz, ngelixa i-WiFi 6 igubungela i-2.4 / 5GHz, igubungela ngokupheleleyo izixhobo eziphantsi kunye nesantya esiphezulu.
Ngokubhekiselele kwimodi yokumodareyitha, i-WiFi 6 isekela i-1024-QAM, ephezulu kune-256-QAM ye-WiFi 5, kwaye inomthamo ophezulu wedatha, oku kuthetha ukuba isantya esiphezulu sokudlulisa idatha.

Ukubambezeleka okusezantsi
I-WiFi 6 ayikona nje ukunyuka kwamazinga okulayisha kunye nokukhuphela, kodwa kwakhona uphuculo olubonakalayo kwingxinano yenethiwekhi, ukuvumela izixhobo ezininzi ukuba ziqhagamshelane nenethiwekhi engenazintambo kwaye zibe namava oqhagamshelwano olukhawulezayo oluphezulu, olubangelwa ubukhulu becala MU- MIMO. kunye neOFDMA iitekhnoloji ezintsha.
Umgangatho we-WiFi 5 uxhasa i-MU-MIMO (i-multi-user-input multiple-output) iteknoloji, exhasa kuphela i-downlink, kwaye inokufumana kuphela le teknoloji xa ukhuphela umxholo.I-WiFi 6 ixhasa i-uplink kunye ne-downlink ye-MU-MIMO, oku kuthetha ukuba i-MU-MIMO inokuba namava xa ilayisha kwaye ikhuphela idatha phakathi kwezixhobo eziphathwayo kunye neerotha ezingenazingcingo, ngakumbi ukuphucula ukusetyenziswa kwe-bandwidth yenethiwekhi ezingenazintambo.
Inani eliphezulu lemithombo yedatha yendawo exhaswa yi-WiFi 6 iye yanda ukusuka kwi-4 kwi-WiFi 5 ukuya kwi-8, oko kukuthi, inokuxhasa ubuninzi be-8 × 8 MU-MIMO, enye yezizathu ezibalulekileyo zokwanda okukhulu umyinge we-WiFi 6.
I-WiFi 6 isebenzisa iteknoloji yeOFDMA (i-Orthogonal Frequency Division Multiple Access), eyinguqulelo eguquliweyo yeteknoloji yeOFDM esetyenziswa kwiWiFi 5. Idibanisa iOFDM kunye nobuchwepheshe beFDMA.Emva kokusebenzisa i-OFDM ukuguqula ishaneli ibe ngumqhubi womzali, ezinye ii-subcarriers Itekhnoloji yokuhanjiswa kwedatha yokulayisha kunye nokudlulisa idatha ivumela abasebenzisi abahlukeneyo ukuba babelane ngeshaneli efanayo, ukuvumela izixhobo ezininzi ukuba zifikelele, kunye nexesha elifutshane lokuphendula kunye nokulibaziseka okuphantsi.

Ukongezelela, i-WiFi 6 isebenzisa indlela yokuhanjiswa kweSimboli se-Long DFDM ukunyusa ixesha lokudluliselwa komphathi wesignali ngamnye ukusuka kwi-3.2 μs kwi-WiFi 5 ukuya kwi-12.8 μs, ukunciphisa izinga lokulahleka kwepakethi kunye nezinga lokubuyisela kwakhona, kunye nokwenza ukuhanjiswa kuzinzile.

Umthamo omkhulu
I-WiFi 6 yazisa indlela yoMbala ye-BSS, iphawula isixhobo ngasinye esiqhagamshelwe kwinethiwekhi, kwaye yongeza iilebhile ezihambelanayo kwidatha yayo ngaxeshanye.Xa uhambisa idatha, kukho idilesi ehambelanayo, kwaye inokudluliselwa ngokuthe ngqo ngaphandle kokudideka.

Itekhnoloji yabasebenzisi abaninzi be-MU-MIMO ivumela iitheminali ezininzi ukuba zabelane ngetshaneli yexesha lothungelwano lwekhompyuter, ukuze iiselfowuni/iikhompyuter ezininzi zikwazi ukusefa i-Intanethi ngaxeshanye.Idityaniswe neteknoloji ye-OFDMA, ishaneli nganye phantsi kwenethiwekhi ye-WiFi 6 inokwenza ukuhanjiswa kwedatha ephezulu, ukuphucula abasebenzisi abaninzi. ukukhenkceza, kwaye umthamo mkhulu.

Ikhuselekile
Ukuba ifowuni ye-WiFi 6 (i-router engenacingo) kufuneka iqinisekiswe yi-WiFi Alliance, kufuneka ithathe i-WPA 3 protocol yokhuseleko, ekhuselekileyo.
Ekuqaleni kwe-2018, i-WiFi Alliance ikhuphe isizukulwana esitsha se-WiFi encryption protocol WPA 3, eyinguqulelo ephuculweyo ye-protocol ye-WPA 2 esetyenziswa ngokubanzi.Ukhuseleko luphuculwe ngakumbi, kwaye lunokuthintela ngcono uhlaselo lwe-brute force kunye ne-brute force cracking.
ukonga amandla ngaphezulu
I-WiFi 6 yazisa itekhnoloji ye-TARget Wake Time (TWT), evumela ukucwangciswa okusebenzayo kwexesha lonxibelelwano phakathi kwezixhobo kunye neerutha ezingenazingcingo, ukunciphisa ukusetyenziswa kwee-eriyali zenethiwekhi ezingenazingcingo kunye nexesha lokukhangela uphawu, elinokunciphisa ukusetyenziswa kwamandla ukuya kwinqanaba elithile kunye nokuphucula ibhetri yesixhobo. ubomi.

I-HUANET ibonelela nge-WIFI 6 ONT, ukuba unomdla kuyo, pls uqhagamshelane nathi.
