Inzuzo ye-WIFI 6 ONT

Xa kuthelekiswa nezizukulwana zangaphambili zobuchwepheshe beWiFi, iimpawu eziphambili zesizukulwana esitsha seWiFi 6 zezi:
Xa kuthelekiswa nesizukulwana sangaphambili se-802.11ac WiFi 5, izinga eliphezulu lokudlulisela i-WiFi 6 linyusiwe ukusuka kwi-3.5Gbps yeyokuqala ukuya kwi-9.6Gbps, kwaye isantya sethiyori sinyuke phantse kathathu.
Ngokuphathelele iibhendi zefrikhwensi, iWiFi 5 ibandakanya i-5GHz kuphela, ngelixa iWiFi 6 igubungela i-2.4/5GHz, igubungela ngokupheleleyo izixhobo zesantya esiphantsi nezesantya esiphezulu.
Ngokuphathelele imo ye-modulation, i-WiFi 6 ixhasa i-1024-QAM, ephezulu kune-256-QAM ye-WiFi 5, kwaye inomthamo wedatha ophezulu, oko kuthetha isantya esiphezulu sokudlulisa idatha.

Ubambezelo olusezantsi
I-WiFi 6 ayikokunyuka nje kwamazinga okulayisha nokukhuphela, kodwa ikwaphucula kakhulu ukuxinana kwenethiwekhi, ivumela izixhobo ezininzi ukuba ziqhagamshele kwinethiwekhi engenazingcingo kwaye zibe namava oqhagamshelo oluhamba ngesantya esiphezulu rhoqo, okubangelwa ikakhulu bubuchwepheshe obutsha be-MU-MIMO kunye ne-OFDMA.
Umgangatho weWiFi 5 uxhasa itekhnoloji ye-MU-MIMO (i-multi-user multi-input multiple-output), exhasa i-downlink kuphela, kwaye inokuyifumana le teknoloji kuphela xa ukhuphela umxholo. I-WiFi 6 ixhasa i-uplink kunye ne-downlink MU-MIMO, oko kuthetha ukuba i-MU-MIMO inokufumaneka xa ulayisha kwaye ukhuphela idatha phakathi kwezixhobo eziphathwayo kunye nee-routers ezingenazingcingo, nto leyo ephucula ngakumbi ukusetyenziswa kwe-bandwidth yeenethiwekhi ezingenazingcingo.
Inani eliphezulu lemithombo yedatha yendawo exhaswa yiWiFi 6 lonyusiwe ukusuka kwi-4 kwiWiFi 5 ukuya kwi-8, oko kukuthi, inokuxhasa ubuninzi be-8×8 MU-MIMO, enye yezizathu ezibalulekileyo zokunyuka okukhulu kwesantya seWiFi 6.
I-WiFi 6 isebenzisa iteknoloji ye-OFDMA (Orthogonal Frequency Division Multiple Access), eyinguqulelo ephucukileyo yeteknoloji ye-OFDM esetyenziswa kwi-WiFi 5. Idibanisa iteknoloji ye-OFDM kunye ne-FDMA. Emva kokusebenzisa i-OFDM ukuguqula itshaneli ibe yinkampani ethwala idatha, ezinye ii-subcarriers Iteknoloji yokudlulisa idatha ivumela abasebenzisi abahlukeneyo ukuba babelane ngetshaneli enye, ivumela izixhobo ezininzi ukuba zifikelele, kunye nexesha elifutshane lokuphendula kunye nokulibaziseka okuncinci.

Ukongeza, i-WiFi 6 isebenzisa indlela yokudlulisa i-Long DFDM Symbol ukwandisa ixesha lokudlulisa le-signal carrier nganye ukusuka kwi-3.2 μs kwi-WiFi 5 ukuya kwi-12.8 μs, ukunciphisa izinga lokulahleka kwepakethi kunye nezinga lokudlulisela kwakhona, kunye nokwenza udluliselo lube luzinzile ngakumbi.

Umthamo omkhulu
I-WiFi 6 yazisa indlela yokufaka imibala ye-BSS, iphawula isixhobo ngasinye esiqhagamshelwe kwinethiwekhi, kwaye yongeza iilebheli ezifanayo kwidatha yaso ngaxeshanye. Xa kuthunyelwa idatha, kukho idilesi ehambelanayo, kwaye inokudluliselwa ngokuthe ngqo ngaphandle kokudideka.

Itekhnoloji ye-MU-MIMO yabasebenzisi abaninzi ivumela ii-terminals ezininzi ukuba zabelane ngetshaneli yexesha lenethiwekhi yekhompyutha, ukuze iifowuni/iikhompyutha ezininzi zikwazi ukuphequlula i-intanethi ngaxeshanye. Idityaniswe netekhnoloji ye-OFDMA, itshaneli nganye ephantsi kwenethiwekhi ye-WiFi 6 inokwenza uthumelo lwedatha olusebenza kakuhle, iphucule abasebenzisi abaninzi. Amava enethiwekhi kwindawo anokuhlangabezana ngcono neemfuno zeendawo ze-WiFi hotspot, ukusetyenziswa kwabasebenzisi abaninzi, kwaye akulula ukuyiqandisa, kwaye umthamo mkhulu.

Ikhuselekile ngakumbi
Ukuba isixhobo seWiFi 6 (i-router engenazingcingo) kufuneka siqinisekiswe yiWiFi Alliance, kufuneka samkele iprotocol yokhuseleko yeWPA 3, ekhuselekileyo ngakumbi.
Ekuqaleni kuka-2018, iWiFi Alliance ikhuphe isizukulwana esitsha seprotocol yokubethela iWiFi iWPA 3, eyinguqulelo ephuculweyo yeprotocol yeWPA 2 esetyenziswa kakhulu. Ukhuseleko luphuculwe ngakumbi, kwaye lunokuthintela ngcono ukuhlaselwa kwe-brute force kunye nokuqhekeka kwe-brute force.
ukonga amandla ngakumbi
I-WiFi 6 yazisa itekhnoloji ye-TARget Wake Time (TWT), evumela ucwangciso olusebenzayo lwexesha lonxibelelwano phakathi kwezixhobo kunye nee-routers ezingenazingcingo, ukunciphisa ukusetyenziswa kwee-antenna zenethiwekhi ezingenazingcingo kunye nexesha lokukhangela isignali, okunokunciphisa ukusetyenziswa kwamandla ukuya kwinqanaba elithile kwaye kuphucule ubomi bebhetri yesixhobo.
