Inzuzo ye-WIFI 6 ONT

Uma kuqhathaniswa nezizukulwane ezedlule zobuchwepheshe be-WiFi, izici eziyinhloko zesizukulwane esisha se-WiFi 6 yilezi:
Uma kuqhathaniswa nesizukulwane sangaphambilini se-802.11ac WiFi 5, izinga eliphezulu lokudluliswa kwe-WiFi 6 linyusiwe lisuka ku-3.5Gbps langaphambili laya ku-9.6Gbps, futhi isivinini sethiyori senyuke cishe izikhathi ezi-3.
Ngokuya ngamabhendi amafrikhwensi, i-WiFi 5 ihilela i-5GHz kuphela, kuyilapho i-WiFi 6 ivala i-2.4/5GHz, imboza ngokugcwele amadivayisi anesivinini esiphansi kanye nesivinini esikhulu.
Mayelana nemodi yokushintshashintsha, i-WiFi 6 isekela i-1024-QAM, ephakeme kuno-256-QAM ye-WiFi 5, futhi inomthamo wedatha ophakeme, okusho ukuthi isivinini esikhulu sokudlulisa idatha.

Ukubambezeleka okuphansi
I-WiFi 6 ayikona nje kuphela ukwenyuka kwezinga lokulayisha nokulanda, kodwa futhi iyintuthuko enkulu ekuminyana kwenethiwekhi, okuvumela amadivayisi amaningi ukuthi axhumeke kunethiwekhi engenantambo futhi abe nolwazi olungaguquki lokuxhuma ngesivinini esiphezulu, okubangelwa ikakhulukazi i-MU- MIMO. kanye nobuchwepheshe obusha be-OFDMA.
Izinga le-WiFi 5 lisekela ubuchwepheshe be-MU-MIMO (okuningi okuphumayo kwabasebenzisi abaningi), obusekela kuphela i-downlink, futhi engakwazi ukuzwa lobu buchwepheshe kuphela lapho ulanda okuqukethwe.I-WiFi 6 isekela kokubili i-uplink ne-downlink i-MU-MIMO, okusho ukuthi i-MU-MIMO ingaba nesipiliyoni lapho ilayisha futhi ilanda idatha phakathi kwamadivaysi eselula namarutha angenawaya, ithuthukise ngokwengeziwe ukusetshenziswa komkhawulokudonsa wamanethiwekhi angenantambo.
Inombolo enkulu yokusakaza kwedatha yendawo esekelwe i-WiFi 6 inyusiwe isuka ku-4 ku-WiFi 5 yaya ku-8, okusho ukuthi, ingasekela ubuningi obungu-8×8 MU-MIMO, okungesinye sezizathu ezibalulekile zokwanda okuphawulekayo izinga le-WiFi 6.
I-WiFi 6 isebenzisa ubuchwepheshe be-OFDMA (Orthogonal Frequency Division Multiple Access), okuyinguqulo eguquliwe yobuchwepheshe be-OFDM obusetshenziswa ku-WiFi 5. Ihlanganisa ubuchwepheshe be-OFDM ne-FDMA.Ngemva kokusebenzisa i-OFDM ukuguqula isiteshi sibe inkampani yenethiwekhi yomzali, ezinye izinkampani ezingaphansi Ubuchwepheshe bokudlulisa bokulayisha nokudlulisa idatha buvumela abasebenzisi abahlukene ukwabelana ngesiteshi esifanayo, okuvumela amadivayisi amaningi ukuba afinyelele, nesikhathi sokuphendula esifushane kanye nokubambezeleka okuphansi.

Ukwengeza, i-WiFi 6 isebenzisa indlela yokudlulisa i-Long DFDM Symbol ukwandisa isikhathi sokudlulisela senkampani yenethiwekhi ngayinye ukusuka ku-3.2 μs ku-WiFi 5 kuya ku-12.8 μs, ukunciphisa izinga lokulahlekelwa kwephakethe kanye nezinga lokudlulisela kabusha, nokwenza ukudluliselwa kuzinze kakhudlwana.

Umthamo omkhulu
I-WiFi 6 yethula indlela ye-BSS Coloring, imaka idivayisi ngayinye exhunywe kunethiwekhi, futhi yengeza amalebula ahambisanayo kudatha yayo ngesikhathi esifanayo.Lapho udlulisela idatha, kunekheli elihambisanayo, futhi lingadluliselwa ngokuqondile ngaphandle kokudideka.

Ubuchwepheshe be-MU-MIMO obunabasebenzisi abaningi buvumela amatheminali amaningi ukuthi abelane ngeshaneli yesikhathi senethiwekhi yekhompiyutha, ukuze omakhalekhukhwini/amakhompyutha amaningi akwazi ukungena ku-inthanethi ngesikhathi esisodwa.Kuhlanganiswe nobuchwepheshe be-OFDMA, isiteshi ngasinye ngaphansi kwenethiwekhi ye-WiFi 6 singakwazi ukudluliswa kwedatha okusezingeni eliphezulu, sithuthukise abasebenzisi abaningi Okuhlangenwe nakho kwenethiwekhi endaweni yesehlakalo kungahlangabezana kangcono nezidingo zezindawo ze-WiFi hotspot, ukusetshenziswa kwabasebenzisi abaningi, futhi akulula. ukuqanda, futhi umthamo mkhulu.

Kuphephe kakhudlwana
Uma idivayisi ye-WiFi 6 (irutha engenantambo) idinga ukuqinisekiswa yi-WiFi Alliance, kufanele isebenzise iphrothokholi yezokuphepha ye-WPA 3, evikeleke kakhulu.
Ekuqaleni kuka-2018, i-WiFi Alliance yakhipha isizukulwane esisha se-WiFi encryption protocol WPA 3, okuwuhlobo oluthuthukisiwe lwephrothokholi ye-WPA 2 esetshenziswa kabanzi.Ukuvikeleka kuthuthukiswa nakakhulu, futhi kungavimbela kangcono ukuhlaselwa kwe-brute force kanye nokuqhekeka kwe-brute force.
ukonga amandla engeziwe
I-WiFi 6 yethula ubuchwepheshe be-TARget Wake Time (TWT), obuvumela ukuhlela okusebenzayo kwesikhathi sokuxhumana phakathi kwamadivayisi namarutha angenantambo, kwehlise ukusetshenziswa kwezinti zenethiwekhi ezingenantambo nesikhathi sokusesha isignali, okunganciphisa ukusetshenziswa kwamandla ngokwezinga elithile futhi kuthuthukise ibhethri ledivayisi. ukuphila.

I-HUANET ihlinzeka nge-WIFI 6 ONT, uma unentshisekelo kuyo, pls xhumana nathi.
